    I am losing my shit waiting for these to actually be in stock. I have every other part. Several delays on other things but now still waiting for rims. I see that others are getting them and I have no idea why. What the hell is going on?

    First ride... I got them to seal today. I think they lost too much sealant yesterday while inflating so I added a couple of ozs to each tire and they are holding now... we'll see tomorrow.
    These pics show the tire at 25lbs which is too much, I will drop that tomorrow to see where the sweet spot is for me. It's been raining here so I didn't get to play around as much as I'd hoped. There is still some scuzz leftover from the sealant, but the rims look great.

I am 6'5" at 220 lbs, and was thinking I could drop to low to mid 20s psi.
    I'm 176lbs and usually riding with 40lbs of clothes, gear, food. I'm not great about measuring pressure, but I figure I'm around 20 psi +/-2 psi. I'd be pinch flatting every 5mins at 10 psi.

    +1 - same here - I ride rocky rooty trails. I run 20/22 psi in 2.4" tires so I'm probably a bit lower in the Knards, but I don't measure precisely.

    My GF could probably ride Knards close to 10psi.

    Can you post a pic of the Krampus with the all silver wheels?

    Also, if they are not clear coated wont they end up looking like shit in no time? Hazy and black oxidized smudges?

    I was going to wait until I got everything tweaked out and then post it on the Krampus builds thread.
    Dunno about the clear coat, I sure hope so... I would rather ride than polish!

    I thought I would update... a week or so in and I am very happy with the duallys. They hold air well, I haven't had to add any air. I have done a few 1.5'-2' drops and have had no burps.
    I think my original mistake while trying to get a good seal was too much air in the Knards (35lbs). Next time I would probably stop at 25lbs and let them sit to seal. I would still pump them up first without sealant to get them to pop on the rim but then use lower pressure with sealant.
    That's my take on it anyway, live and learn I reckon!

    My tubeless setup: One layer of gorilla tape and WTB valves.
    I put a tube in and inflated to set one bead, then had to use a compressor to get the other bead to pop. I put three cups of Stan's in each tire and inflated to 30psi. Did the shakey-dance and set each wheel on their side. Only one bead was very leaky on each tire. Then they were done. Super easy. If the pressure gets down to the middle single digits I can make the bead leak with my thumb so if you want to run low more safely I'd build up the rim a little bit.

    Tonight I built up a set of black 29er Dually rims on DT 350 hubs with DT Comp spokes and aluminum nipples. Knard 120tpi tubeless with Stan's tape.

    Compared to the stock Krampus wheels (RH rims, Surly front, Shimano M525 rear hub, DT straight gauge spokes and 27tpi Knards tubeless w Gorilla tape) the new wheels are 1025 grams lighter.

    What tension is everyone shooting for?

    Using the 604 ERD I'm getting a spoke length of 293 ish rear on both sides and 292 front non drive side (disk side) using CK hubs and a SS rear. 3x.

    Bump! Planning to lace these up this weekend, what tension levels should I shoot for? 110 or so?

    I did 110kgf on the rear DS, 100kgf on the front NDS. Don't want to go too high, that long flat fairly thin cross section would be prone to cracking at higher tensions I imagine.

    Think 293 for all would be ok?

    My eyes aren't good enough to read that...

    A few standard spoke length ?'s:
    -Did you measure the rims yourself?
    -Do you measure to the end of the nipple, or to the bottom of the slot in the nipple?

    Build the rim up? You mean with multiple layers of tape? How wide?

    Dually 26

    I'd post this as a review, but the Dually is not listed. I owned two Dually 26 rims briefly. They were returned to my LBS after I took the plastic wrap off and found several cracks in the outer wall. The photos show only a small area on each rim, there were more cracks around the circumference. Very disappointed. I hope this is a problem that Velocity can resolve, until then I would recommend checking your Duallys for cracks. I will probably wait until Stans 50 mm rim is available.

    got some 29" Dually built up at the local bike shop.
    before putting on some tape, found some dings, and don't think the bike shop is throwing around the rims. the way they looked, it was anodized afterwards.
    not good. also all the holes have sharp edges, ok, exacto knife out another half hour and then vacuuming the splinter. put the tape on, ok, 1,2,3 ; 1x in the middle, and 2 outside. that means more then 1 roll. the valve hole, had also sharp edges, and is really small, why ? ever seen the stans tubeless valves, this suppose to be tubeless ready , remember ,.... fix this. put on an conti MK II, loose, ok, lets see, airs up, but leaks, leaks the balls, did it 2x. using fenwicks goop. took it for a slow ride, had to constantly air it up. ok, take my maxxis , chunky monkey, that one seals up, even without goop, usually ride around 18psi with it. that one leaks too.
    how many layers does it take ? 20 bucks extra, come on, why.
    and no beadlock !? no, not even a straight shelf, tapers right off. not good.
    maybe good to get the tire on, especially off, in the most inconvenient time .
    at least one hurray, the the spoke holes, did not come in a straight line, a little offset spread, still not angled, but it's a start.
    have not tried a UST tire, like the wtb bronson, but what's the point, with that rim, want beefy 2.4,2.5 maxxis DH tires, conti trail kings , etc, maybe some lighter schwalbes, point is, tolerances need to be tighter. should'nt need 20 foot of tape, should work just covering up the hole.
    guess I'll buy some more tape by the bucket; have an minion DHR II waiting and TK coming. in comparison wtb tis is painless.
    - no shiny polished available
    - holes have sharp edges
    - valve hole to small
    - no bead lock
    - bead shelf, has no straight ledge
    - banged up and scratched out of the box
    - made in the USA sticker, would wait on that one, till you get it right
    - one more where it is pinned, sharp edge !?

    guess I got to get some steel wool by the bucket too.
    should invest in the dremel, to at least get the edge on the pinned section smooth.

    wanna try again, send me 2 build.

    one more, maybe measuring it, and put it on the label, so we get an idea , how many layers of tape. cheers , Rob

    We've been building to our usual 120kgf DS for what it's worth, haven't seen any problems thus far. Anything in the 110-120 range should be okay, I'd imagine.

    We've never clear coated our polished rims, and they've held up great in long-term testing. No more cleaning or maintenance than any other finish we've tried.

    My Dually & Blunt 35 both arrived yesterday and I'm bummed to say that mine have the same list of issues that Rob & Flying Squirrel report. I'll talk a better look at them tonight and see if I can make them work. Not too excited about having to send them back but that might be what I have to do...

    update:
    since I wanted to ride, I stuck a tube in the rear. with a fat tire and tube, it's no fun riding. since you still got to have it aired up enough , not to pinch-flat. so no points here.
    took the front to prep, scraped all the edges off the holes, and dings.
    got some kichen scrubs, steel wool, and the plastic pads, for the pan, went to town,
    and scrubed all the inside of the rim.
    dug out an maxxis DHR II, one of my new favorites, besides the chunky monkey,
    put a center layer on the rim, used soap water, on the bead, aired up with floor pump, getting strong arms by now,...
    no pops, leaks, argh, beads ok, still farts when pinched, what is that ? why ?
    major leak, around the valve !! took a break, refuel, get a heini, ponder.
    ok, time to fix that. measure, drill, alu, check, ok ready, drill 6.9mm rim out.
    argh, have to waste more stans tape, no,; drill through the tape, tapered degrate 30deg,
    used exacto knife to remove frazzled edges. back to mounting, pumping, soap water.
    got one pop, 50psi. no leak on valve.
    back to home depot, for some rubber tape, extra thick vinyl, low temp high grade.
    next, to use 0.9mm rubber tape, to create a bead-lock .
    oh, no sealant on the DHR II, usually use Fenwicks blue soup. for now I'll test without the goop. michelins wild'race, also hold air without it. but the roots, cut of stumps, and thorns, rip it to shreds. also at low psi, especially in the rear, it's just to wobbly .
    since the MK II 2.4 did not hold. also leaks on sidewalls, without stans.
    thinking, I'll go with the 1kg, wtb TCS AM vigilante to test further. they are UST tires, with extra heavy sidewalls. should fit the bill, in the rear. still want to get some TK II, 2.4 in BC protection to try.
    back to bead-lock, definitely want it, especially in the front, thought the rear will see a lot more torque and side pressure.
    give me a tickle, will order more rubber to test, cheers, Rob

    150 technical rocky miles on a pair of 29er Dually rims with Knards, ghetto tubeless. Almost all loaded bikepacking. I'm 180 lbs.

    Zero issues.

    Just finishing building my Duallys. I'll be trying to make them go tubeless tonight or tomorrow morning with Knards. BUT, my current plan to build up a bead lip with super thin strips of tape, then go over the whole thing with a layer Gorilla tape. Maybe two layers if they won't inflate easily.

    I've got Velocity tubeless valves which fit with zero hassle.

    I have several hundred miles on a pair of 26er Dually rims. Used 25mm stans tape and have a Husker Du on the front with a Knard on the rear. So far everything has been flawless. They built up really well, set them up easily tubeless with a hand pump, 2 scoops of stans sealant and they have been holding air really well. I have done a couple races on them as well as hard riding and generally run 9-11psi with no burps or other issues. Any lower than that and I was running into issues with the tire getting floppy under hard cornering. I weigh in around 200lbs and ride pretty aggressively so I feel like I have given them a good test up to this point. So far I am very impressed with them.

    Is tubeless really worth it? I guess I just don't get it.

    Any report about 2.4" tires on Dually rims?

    I'd take a pair of Dually rims to go with a 2.4 Ardent rear and a Knard (or better a Dirty Wizard if it'll be available) front. All on a Canfield Yelli Screamy with Fox34.

    What do you think about it?
    I'm riding Ardents on P35 F&R, at now.

    My black Duallys built up super easy. True as hell, no fuss. Look great. I used Stan's wide tape with a 120tpi Knard on the front and a 27tpi Knard on the back. The front set up with a floor pump, but bubbled after rides for a few days near the bead. Good to go now.

    The rear wire bead was a pain in the butt. I couldn't get it to seal and had to take it to a friends house with a compressor and use a ratchet strap. Good to go, no leaking at all.

    Have had two real rides and several commutes with no issues.

    I was using some tubes I had laying around, admittedly heavy, but saved 1.2 pounds going to tubeless. Totally worth it. I would def. but the Duallys again. No complaints.

    Sorry for the delayed response. We've found 2.4's are perfect on a Dually... we've run as narrow as a ~2.3 with great success, as the Dually itself is around 1.8" wide. I say go for it, but I'm a bit biased.

    I've not seen either of you post since sharing the pics of the cracks in new rims so i'm curious how it was handled and resolved if so.

    I got a second opinion and we decided that the scoring that I found in the inner wall wasn't actually a crack. Maybe when drilling the rims, the bit dragged when they went from one hole to the next. I decided to live with the rest of the cosmetic imperfections. Hopefully they are only cosmetic. The wheels have been built but I haven't gotten to ride them yet and I haven't even mounted tires. I'm still waiting on the frame that they will go on (a Singular Gryphon). They do look awesome!

    ^^ Much thanks for the reply.

    Seely whats your thoughts pertaining to flyingsqrl and his issue? Has it been looked into and what was determined?
    Lastly if one were inclined to have the rims anodized would it be best to start with the polished versions?

    I took the Duallys back to my LBS and got my money back. I'm glad to hear that many others didn't have the same problem with their Duallys.

    update: useing dually with tubes, till I get an compressor, and build-up a beadlock.
    got the studded nicotine tires, great tires, but so loose on the rims, guess , those where not meant to be used tubeless.
    and 69tr6, , yes tubeless is worth it. not just weight, rolling resistance, but the snake-bite flats due lower pressure. buddy has a Krampus , and he got tired of all the flats.

    Sorry to hear about the cosmetic issues, but glad to hear you're giving them a shot. Hopefully we've got the production line dialed in now to the point where that's going to be behind us. Post back once you get a few rides on them, we're always eager to hear feedback on a new product. So far, it seems pretty favorable so I hope you'll have the same experience.

    From my own casual observations with non-tubeless tires it seems that the tire fit varies more with these higher volume tires -- seemingly more so than with "normal" volume tires. With tubeless tires, the success rate seems to be pretty consistent, however. Keep us posted on what you find.

    We got the rims back (not sure whose set it was exactly) but it does appear to be a flaw somewhere along the line in the manufacturing process. We discovered a gouge in a spoke hole on the *inner* rim which is less than desirable, but shouldn't pose a strength issue as the nipple primarily stresses the outer rim wall. My guess is it was during the drilling process, but it's hard to say with 100% certainty since we really haven't seen the issue since. There was also a scratch along the inner web that looked like a possible manufacturing flaw as well, again, not ideal but not something we'd see as a structural issue. In fact, I believe an employee snagged the gouged rim and built it up for himself. We alerted the factory to the issue, and have no heard of any similar defects since so we expect it was limited to a few earlier production rims.

    For the anodizing, you can actually use either the Mill or Polished rim. I'm told the Polished rim will change the sheen of the anodizing process a bit and looks pretty sharp, but our standard practice is to send out the mill finished rims for anodizing.

    Dually's on my 616 tubeless with 45NRTH 26x4.0 Dillingers. No problems unless I go under 5psi with the setup. Tires have stayed on rim fine, just burping air at lower tire pressure.

    Been riding a set of Duallys since early December and no problems so far. Using a 26x2.8 tire and not tubeless yet. Built up on Deore xt hubs under a 1x9 steel hardtail.

    I have a set of Dually wheels on the way from Prowheelbuilder.com, they will be going on my Ogre frame. I don't think Knards will fit the rear, I am going to run Ardent 2.4's to start. Frame is being repainted, will post pics when done.

    26 & 29 Duallys

    I have a set of each here. one on the Singular has on One Smorgasbord rear/Chunky Monkey front. Both tubeless. The front barely clears the Reba Too close really. I have to look for a different sus fork. The Duallys on the Mukluk are tubeless with Fatback Sterling tires. No problems with that set up at all.

    Under 10 psi on a 3" tire? Wow. I'm lighter than you and can't get anywhere close to that without taking rocks into the rim.

    Are you riding snow or dirt?

    Im hitting the rocks,roots, dirt.
    I actually didn't care for the tire size until I bought a nice pressure gauge anddropped the psi- I think I might have been running 12 for awhile. That was the sweet spot. 12 rear and 10 front now I'm remembering.
    I normally run 25 on my race bike, 10 on the fatbike and 10/12 on my 29+

    I built an ECR with Duallys and 120tpi Knards and took it noodling in some mild chunk yesterday. I was thinking that I could have run less pressure until I got a couple burps at 12psi.

    I wish Bontrager would make their tubeless rim strips for everyone else's rims.

    Wow! Y'all must be skinny! I am still running closer to 17-18, course I am a big boy at 215-220lbs depending on the beers consumed over the weekend. I tried it around 15 and started worrying about the rims on heavy hits.

    ECR's now available ? what's the difference to Krampus ?
    how are those 120tpi Knards ? thinking they might be to squirreley for me 200lbs,
    the 27tpi knards have a wire, they might burp less.

    I'm running the Dirt Wizards on mine and keep them pretty plump for less rolling resistance. I don't measure the psi but even at high psi the wizards are still pretty soft and grippy.

    Nope, sorry, 26". The Duallys are taking a beating though since I'm a rather clumsy rider. "Point and Shoot" is my motto.

    I've been riding a set of 700c Duallys on my prototype Singular Rooster 29+, and they're fantastic rims. Tubeless setup was very easy, even with non-tubeless Knards.

    I've had good friends run the 26-inch version on their racing fat bike, and they worked well in that application. They aren't the ticket for deep, soft snow (where 80-100mm rims rule), but for most all other conditions, the weight savings is awesome (esp. given the reasonable price).New Velocity "mid fat" rim, the Dually-image.jpgNew Velocity "mid fat" rim, the Dually-image.jpg

    I just ordered the ECR frame set and only had to wait a week to get a large. I haven't tried the Knards on any other rims and they were tough to get inflated on the duallys but they roll well enough and grip like crazy for climbing!

    Would anyone know specific tire widths of an Ardent 2.4 on a Dually? I saw info here regarding the Dually not really changing the Ardent's profile but just wanted to make sure. I'm planning to use this combo for my rear, paired with a rabbit hole - knard combo on the front. Based on my own measurements I can fit a 62mm tire in my frame, so would the Dually - Ardent 2.4 combo fit? Thanks.

    My thoughts after more than 5000km.

    I published a long term review on my blog: Longterm review: 6000km on Velocity Dually 29? Rims | Off Route

    Most of it is my thoughts on running them tubeless, and how a got them to successfully/safely go tubeless.

    Take home message: the "tubeless-ready" claims by Velocity are bogus, but with a bit of creativity, they can be made ghetto-tubeless relatively easily. But so can Rabbit Holes.

    The claims are not at all bogus. Use a tire that has a bead made for tubeless and you will not have problems. I set up some Specialized 2bliss ready tires with no problems a few weeks back and have had no issues. I wish Surly would come out with tubeless versions of their tires.

    Thanks for pointing this out. Other companies seem to choose to make their rims to cater to tubeless conversions, while we make ours to be compatible with actual tubeless tires. Surly tires seem to have the widest range of success and failure running tubeless. I've had reports of everything from one layer of Velotape or Stans, to 5 to 6 layers of Gorilla tape to screw it I'll just run tubes.

    Personally, I'm running the 26" Dirt Wizard and wound up using a layer of Velotape and then a layer of a thick rubbery tape. Even then I only got the tire to seat after wrapping it tightly with some of our packing wrap. It's holding great, but Surly tires have loose tolerances and certainly were not designed for tubeless applications.

    I have the Dually front with a Knard and Blunt 35 with a X-King neither or which are tubeless specific and I haven't had any problems in the 5 months or so that I've had this setup. Just using the Velocity blue tape with the valves. It was quite tough to get the Knard set up tubeless but the trick that I found is to air it up with the wheel laying on its side on a garbage can so that the Stans pools on one side then flip it over continuing to give it air. It took a good 10 to 15 minutes of keeping air on it with a lot of sealant lost before it would seal. Haven't had any issues though since.

    What kind of pressures are you guys running with your Knards and Dually's tubeless?

    I ran with tubes for about a week just to get them seating well and to help set the single strip of stans tape over the spoke holes, and they worked fine at about 10 pounds PSI with tubes in rocky terrain.

    I then just carefully took the bead off one side, pulled the tube and put 3 scoops of orange seal in. Did this over at my local LBS and used there air compressor and it sealed right up with a little leaking around the beads that went away soon.

    Problem is I can't even run the pressures as low as I was with tubes as I get small burps with sealant coming out.

    skylerd from your description it sounds like I need to build up the shelf a bit with some gorilla tape, how many wraps around the rim do you do? Do you leave a little room between the side wall and the tape or are you butting the tape right up to the sidewall?

    Thanks

    Really looking forward to the Maxxis Chronicle coming out as it looks to be a tubeless tire with sidewall protection.

    I've run mine tubeless with Knard, Nobby Nic, and Racing Ralph. The Schwalbe tires got on the bead seat better but still burp at higher pressures than I want to run (16psi). The Knards suck to get seated and are really too loose on the bead seat, IMHO.

    I anxiously await fat rims from Notubes and would have built this bike on Flows in the meantime if I had known.

    Yes, I say this in my review. I know that Surly tires are not tubeless ready. I'm referring specifically that I had to try to build a bead shelf out of tape. You'll notice that I'm the only person who has done that, and I seem to be one of very few people responding that has never had a tire burp. If you read my review, you'll notice that it's really positive...if that's what you're worried about.

    And it should be, I've thrashed around on them for nearly 6000km.

    I did read your review, quite carefully. What I am confused on is how a successful tubeless setup with a non-tubeless tire somehow makes our claim of tubeless ready "bogus."

    Problem is I can't even run the pressures as low as I was with tubes as I get small burps with sealant coming out.

    giantone from your description it sounds like I need to build up the shelf a bit with some gorilla tape, how many wraps around the rim do you do? Do you leave a little room between the side wall and the tape or are you butting the tape right up to the sidewall?

    Thanks

    Really looking forward to the Maxxis Chronicle coming out as it looks to be a tubeless tire with sidewall protection.
    We recommend going edge to edge with the tape, even for UST tire applications. If you're running non-tubeless tires, Gorilla Tape may work better than our thin stuff.

    Right. It's just the lack of bead shelve ridges that I'm referring to. I guess that makes them "almost tubeless-ready", requiring just a bit of modification. Seems that with the tape shelf, the risk of burping is way lower. The diameter is clearly correct for airing up tubeless-ready tires without full-width tape, the profile just might not be correct for keeping them there.

    If the Duallies had a bead shelf ridge, they'd be a 5-star product. It's what people want. It would probably be a lot easier to make rims with bead shelf ridges than to convince people that they don't need them.

    I have a set of Duallies I have been running on my FS bike. For tires I am some old 2.4 kendas that I had hanging around, the only reason I am using them is I wanted something more aggressive than knards. Still waiting for a 3 inch aggressive tire.
    I found the Duallies to work very well tubeless with thin tape, they have a good shelf that the tire sealed on before it popped onto the bead. I think surly tires suck I have several pairs of surly fat tires, the quality has no consistence. One tire will fit tight the other will almost fall off the rim. I think like stated before it a tire problem not a rim problem.

    I just had Angry Catfish, in Minneapolis, build a 29+ wheel set for my Mukluk using the Duallies. They are built around I-9 hubs, and use the 29x3 Knards, set up with tubes for now. The Duallies were cheaper than Rabbit Holes, but the added expense of the hubs (vs. Salsa hubs) more than offset the savings....

    I plan on using the bike to explore forest roads and trails and figured these would be better at covering distance than the stock Mukluk wheel set.

    So what's the most reliable tubeless setup for the Dually/Knard combo for aggressive riding? I built my Dually wheelset last week and just picked up some Gorilla tape today. Some say to use no tape, just sealant, some say 1 layer, some say 2 layers. Experience?

    You will need tape, no questions asked they simply will not work without it. I would suggest this stuff 3M Scotch Transparent Duct Tape, 1.88-Inch by 20-Yard (2120-A) - - Amazon.com It is slightly wider than you need so it will need to be trimmed down. Tape the entire flat area including bead shelf and you should not have any troubles. Gorilla tape will work but it is heavier and tends to soak up a bit more sealant. My experience was with a trouble free gorilla tape setup that only covered the spoke holes. It was fine but the gorilla tape ended up soaking up more sealant than I would have liked.

    For my 26er Dually/Husker (front), Dually/Knard (rear) I needed one layer of Gorilla tape to make the rim/tire interface tight enough to not burp. With just stans tape I peeled the tire off.

    I've seen the most variance in tubeless setup with Surly tires. I love my Dirt Wizards, but on the 26" Dually they were a very loose fit. Others have said theirs fit tight. Guitar Ted, in one of his reviews, mounted Knards easily with a single layer of Gorilla Tape. One of our wheel builders here wound up using 3 or 4 layers. So, all that to say YMMV. With any non-tubeless tire it seems to require some experimentation.

    That's what I was thinking. My Knards ( ) are a pretty loose fit. I am sort of expecting at least 2 layers, but wanted to see what others had done. I'll post up when I have time to convert and then again after the first ride.

    I've got a few more long rides in rocky terrain under my belt, never got around to building up the bead shelf, still have a single thin layer of Stans tape covering the the spoke holes and still using the original 3 scoops of Orange seal. I seem to be able to run lower pressures now than originally for what ever reason, maybe enough orange seal has bedded in around the bead. Last Sunday I ran 10 1/2 PSI in both the tires with no issues. These are 120 tpi knards BTW.

    Here I am starting to descend 4500 feet last Sunday

    Been running mine with the 27tpi versions since last October with zero issues. They were a ***** to get sealed but once I did they are great. I figured out it was best just to put in about 20 lbs of air and let them rest on each side for a few hours. I run about 12-14 lbs no problem.

    Any tubeless Dually experience with 29+ tires other than the Knard?

    Well, I spoke too soon. I changed out to 2 new Knards yesterday and have been trying for two days to get one of them to seal. Stan's is blowing out both sides and neither side will seal. It has been resting on each side for hours between flips and still will not seal. Grrr.

    My friends had the same problem with Duallys. If you can't get it to seal try a split tube.

    Thanks vikb,
    Not sure I understand, isn't the split tube method for the rims? The tape is holding up fine, it is blowing out between the tire and the rim.
    Thanks

    The split tube lets the tire seal against the split tube which is between the tire bead and the rim.

    See this post: Fatbike Tubeless | gypsy by trade

    You don't need any foam with your Duallys. I'd put some tape over the spoke holes [doesn't need to be air tight this is just for abrasion protection of tube.] then add split tube and tire. Finally trim excess tube that's hanging over edge of rim.

    OK Thanks for the tip. Weird, I haven't had a problem for the past year. I guess the Knard is wonky?
    Thanks

    The Dually isn't a good tubeless rim and the Knard isn't a tubeless tire. Combine the two and you have a total crap shoot for getting a seal. The split tube bridges the gap between the two and should solve your problems.
