    RST F1RST Air 24"

    I see that the Scott Scale Jr has the new 24" RST Air fork. Hopefully we can buy this fork by itself soon. Or the Spinner Air, or Suntour Air. Anything please!

    Sounds good Nick, but would that be January or November? Any idea what retailers are the most likely to carry it?

    January 1, 2012. Not sure about retailer specific but Distributors can order them from us around that time or we can sell consumer direct.

    Scott's website list the "Fork: RST Capa T24, 24" which isn't an air fork.
    SCOTT Scale JR 24 - Bike Junior's
    RST

    Where are you getting this info?
    I'm tossing back and forth between the Specialized A1 and The Scott Scale - Air fork on the Scott could lean me toward the Scott.

    Yeah. $999 for a bike with rim brakes, just like the Specialized 24 I bought on CL for $40.

    Not quite. It's under 23lbs with 3 chain rings, air fork, XT derailleur, and light wheels. The specialized is about 27lbs. Light wheels would probably run another $300-$400 unless you score something prebuilt. The air fork...still in search of, but will likely be $300+, if ever found. Still cheaper to piece it together yourself for sure. I would definitely buy a used and modify (big fan of that for generic kid situations), but buying new and not having to modify, there aren't many choices out there for a weight weenie 24incher.

    Rim brakes are quite effective, and have been used for decades with no issues unless you get it wet, but it dries quickly. If you're looking to keep weight down, and costs, rim is more effective than disc in that regard. Disc is 3x heavier at least, for the whole brake system. Top of the line v-brakes are cheaper than top of the line discs, for a cost comparison. I wouldn't hesitate to use rim for my kids, because I'm not going to take them into the mud. Cleaning my own bike, and all the laundry surrounding it and my riding gear, is a PITA already! Riding in the rain, they should do cautiously anyway, but discs will howl like mad in that situation, so it's a wash.

    SR Suntour can sell consumer direct if your local dealer is unable to get the fork you are after. We do have a sizeable distribution chain here in the USA.

    I agree, the bike I'm building will be about $600-700 and a hell of a lot better speced than the Scott.

    Thanks Nick, I'll start doing searches come Jan. 1st. Not cheap, but it'll be handed down at least once...

    Nice price, a bit heavy though.

    Is the A2C correct on your web page? 481mm is taller than a 100mm 26" fork. Your XCT Jr is 416mm.

    Yeah, I was hoping it would be in the 1750's or so. Looking forward to something with low stiction and air tune-ability, hopefully this delivers.

    Not even close. Those wheels on the Scale RC are way lighter than any other 24" wheels you'll find. These would also be the wheels you want to transfer over to a 26 XS build.
    The rim brakes on that bike are excellent, I was very suprised how well they worked even winter riding in the snow & there very light. Don't forget your going to get a descent buck for a bike like that when you sell it.

    Actually incorrect, to make a 24wheeled XS26er you want disc hub because the rim brakes won't line up

    Nope, you just need adaptors like on this one.This is a 26" fork, I may just take the entire front end off this 24" bike a put it on a 26" XS when the time comes.

    Hopefully it is 418mm. If it is 481 I wouldn't even consider it as most 80mm 26" forks are around 455.

    Where'd you get those adapters? When I was looking, I didn't find any other than a custom bracket you have to make or have made. I'm going with discs, because it's an off the shelf solution.

    Most are just home made, its not to difficult to make them. I have a friend with a CNC machine, so he made this one for me.

    See for most of us that don't have friends that can machine something, it's cheaper to go disks.

    I'll draw something up and see what the machine shop we work with would charge to make it. Probably cost as much as the fork itself though...

    Two Tone you don't need a CNC machine to make these. Could probably start with this & minor mods.Xtracycle 26" to 700c Brake Post Conversion Adapter | | Bike Trailer Shop
    A couple of home made ones in here.Custom brake adaptor for V-brakes
    As you know kids bikes are tanks, so just a way to try and keep the weight down.

    Another alternative over a big arch is a post adapter. click here

    IIRC, these are for 650b rims on 26" forks. I've been thinking of running these inverted from the pic to run 24" on a 26" fork.

    Give it a shot and let us know how it works out.

    I used the Sinz version made for bmx bikes.
    http://www.sinz-racing.com/product/SBPE-01.html

    I had to invert them and modify a bit for 24" wheels on a 26" wheel frame. It turned out ok but the adapters only provide 16mm of positioning, luckily I had some old rockhopper v-brakes with enough adjustment to make up the difference.

    A design like this certainly will be cheaper to have machined.

    Already got the regular Spark 24. Upgraded the rear shock, will wait for the fork.. Would have been easier to find the Spark RC, or Scale RC, better wheelset and all, but I did not.

    Not sure how you fit that in $600.

    Of course, if I was counting parts that I moved over from bike to bike, some of my bikes are for free... That's what I tell my wife..

    Ordered Schwalbe Mow Joe 24's..

    I work from home so I can Ebay up on my other PC. I've been lucky to find under valued items on buy it nows.
    2 examples, the full BB7 set was only $60, normally auctions go much higher. Actually same guy the XT drive train was $60, since same seller saved on shipping
    The frame and fork were $175 buy it now, saw a frame alone auction up to $165 4 weeks later.

    And it will most likely end up closer to the $700 side of things.

    It's the new year! Hopefully I can find one of these soon... Almost pulled the trigger and built up some 24" disc hubbed wheels and went 26" fork.

    SR Suntour said they can do consumer direct @ $230 after the new year. Have you looked into that? Do they charge shipping and tax? Yeah, I know I could ask them, but I figured you did already and have that information.

    I'm a little confused with the Suntour fork. On their website it states that it has a coil spring but that the system is air?

    What does this mean? Is it a type, or is it like the fork I have on my mountain bike that has a steel spring in one leg and an air spring in the other leg for tune-ability?

    Also I note that the page states 165mm travel! Whereas below that it then states 65mm. I guess the spring statement may be a typo along with the 165mm. SR Suntour needs to proof read their webpages prior to publishing. It doesn't exactly inspire confidence in the product...

    It's a typo, if you expand the spec is shows 65mm, plus air spring in right side, negative spring in left. Also check out page 71 of the catalog. 1860g though, wish it was lighter.

    Yeah, existing over there isn't the same as over here.I suspect they are just working their way through the channels. As new part numbers they are probably fullfilling OEM orders like to Scott etc. K-man said that Ibex was going to add an air fork, so they probably order in some qty. direct from China/Taiwan. I don't feel like waiting, but I suspect some ebay sellers will have them in a month or two.

    1600g is OK, but I'd want to see one of those actually on a scale. Some of those taiwan guys have a bad habit of quoting weights without the steerer.

    If you're looking to save weight and get some tunability then an older 28mm chassis SID travel reduced to 60mm with a DIY v-brake adapter or better still lightweight 24" disc front wheel is still the best option.

    A mag21 with the long travel mod and some homemade brake boss relocation brackets makes an OK 24" fork, but XC71's SID fork would be much better for an aggressive rider.

    I'm currently looking at options to build my younger daughter a 24" bike and I think I will use a 28mm SID travel reduced to 60mm (or thereabouts), run a front disc with a spare a2z front hub, DT rev spokes and Alex ACE20 rim. Fork will be around 1300g and front wheel around 650g.

    Yep, you're right that that weight prolly doesn't include steerer. I'd love to see what your builds look like! I want to do similar, but to be honest by the time I researched spoke lengths, hubs and rims etc. my kids will both be riding 26'ers. I just want a moderate weight loss, but more importantly a tune-able air shock that has some damping and hopefully a bit of plushness. I just bought a used Juliana XS frame to build a 26 FS for my son (Need to apply blue flame stickers over the name before he sees!) so he can move off the 24" bike this summer. Have a Reba Race, discs and reasonable wheels. If the new fork will make the 24" bike reasonable I'm sure my daughter can ride trails just fine for a year, maybe two on it. I'd love it if my kids were out there killing it enough that the bikes were holding them back, but to be honest they aren't....

    I am more concerned about fork actually working well then just saving weight. Not sure about SID - and have not seen good examples for sale recently.

    I have scales on order so I'll be able to weight it. Why would you think this bike would be heavy?

    It the Specialized M4 alloy with a light Skareb fork. When I was looking at buying it, the guy weight frame, fork, BB and headset and it came in somewhere around 6 lbs.

    I have a really nice set of 24 inch wheels, that have light rims and hubs.

    Here's the link to the cranks I'll be using.

    Cool, thanks for the link to the shortened cranks. Building an XS Juliana for my son as he moves off the 24" bike and was wondering what to do about cranks. He might make 165, but it's nice to have options...

    I got the same cranks as linked, but in 145mm. I think 155mm is already in the XS 26" territory, just by scaling body size. I plan to run them with 24-36-bash chainrings.

    28mm SIDs are perfect for a kids bike (but too flexy for adults) and can be tuned to work well. Manitou R7 is a good option as well. Not as light as a SID, but the Manitou has a much better shimmed damper that is easier to tune for lighter riders. Manitou R7 can be had for around $300 new and sometimes much less.

    Really! Cool. What are you doing with those 15, selling individually or building bikes out of them?

    I've given up trying to get 24" forks. I have managed to pick up an old 26" SID 63mm which has an axle crown distance of 435mm only 15mm (~1/2") different from the sa suntour stock junk on the 24" hotrocks, so it shouldn't mess with geometry. Needs a rebuild which could be a challenge to get the bits - but as I only paid $15 for the forks it's no big drama if it doesn't work out - except for the fact the bike will still be stuck with a junk fork

    Received the Suntour fork today. Weighs 1868grams with uncut steerer. Cutting the steerer will save another 68 grams i hope. Sure will save 300 to 400 grams compaired with the old fork. Unfortunately i will see my son on August 28. So you will have to wait for a riding report.....

    Going to shave some weight of his bike with this fork and a Thomson Elite seatpost and Deore v-brake set (instead of a no-brand brake system which operates way to heavy for kids...)

    At last...next week I will meet my son and we can mount his new fork. So next week I will be able to share some expierences. I will take my scale along to weigh the fork with cut to fit steerer.

    @Axe: that is sh%^%$ that the seller never responded...

    WOW, that Spinner fork is really lightweight!! I have contacted the Spinner dealer in EU but he didn't have any 24" forks in stock....

    Does anyone have any experience tuning the RST F1RST Air 24"? My son weighs about 65 pounds and his fork often doesn't fully rebound. I realize that I can put more air in, but when I do so, then the shock doesn't have much travel. Increase the rebound more? Anybody know how to set up this fork for a lightweight rider?
    Thanks.

    Mine is in the mail, but when I install it I'll let you know if mine behaves similarly and if I have any ideas what to do about it.

    First report of the Suntour XC-R lo. I have cut about 10cm off shaving about 50 grams of the 18XXgrams (see former post). The fork works very well. Pressure set on 80psi and that ofcourse is depending on weight of the rider.

    With 80psi there is a real usable travel of about 2inches / 5cm. Better than the coil Suntour fork that came with the bike. The coil fork released only 1 inch on massive bumps. The coil had no sag were the airfork has a bit sag with the correct pressure.

    Overall my son is very happy with his new fork. He had very little issues with his wrists on bumpy sections.

    Thanks for the info on the fork set up. How did you set up the rebound and with 80psi how much does your son weigh? At this pressure can he compress the fork by pushing down on the handlebars or just when he hits large bumps.

    My son is 9 and weighs about 65 pounds and I'm running much lower air pressure with the belief (might be dead wrong), that he should be able to engage the shock by pushing down on the handlebars. To make this happen I'm using much lower pressure, but the fork sometimes sticks.

    Thoughts or comments are welcome by any and all to help me tune this fork.

    My son is 9 and weighs about 65 pounds and I'm running much lower air pressure with the belief (might be dead wrong), that he should be able to engage the shock by pushing down on the handlebars. To make this happen I'm using much lower pressure, but the fork sometimes sticks.

    Thoughts or comments are welcome by any and all to help me tune this fork.
    I don't know this fork specifically, but with most forks you set them to have about 25% sag. That means that with the rider sitting with their full weight on the bike (legs up, someone holding them, helps to do this in a doorway so they can hold themselves up) the suspension will go down and stay at 25% below the top of the travel. So, if it is an 80mm travel fork it will sag 20mm.

    Just an FYI for anyone with this fork. I have increased the air pressure to 55psi for my son who weighs 65 pounds and have completed eliminated the sticking problem. This is good but don't seem to get the full 60mm travel due to the higher psi. I'm going to keep tuning it while he gains weight and will let you know if I see any other improvements.

    Happy trails with you kids!

    The fork for my daughters bike is in, sitting on the workbench for the moment though. Hopefully get it installed next weekend and see how the tuning goes. Thanks for the info!

    I have missed your post, i'm sorry.

    I have not measured sag actually. I have put 100psi at first in the fork and went out for a ride. Since the fork did not give complete travel i have lowered the pressure. 80psi was just fine. There is a little sag and yes he can compress the fork just by 'rocking' the handlebar. At the end of the trail you can measure travel due to the dust collecting on the stanchions.

    I have no clue what weight my son is.......

    This post is useless without pictures. On the scale, preferably.

    I did get a manual with mine, and here is a scan of the recommended air pressure plus a quick xl conversion of kg to lbs. 80 psi is way too much. I'm running about 35 for my 45lb daughter. Threre is a bit of sticktion that the low pressure cannot overcome which does prevent the shock form extending it final 2-3mm, but that's really inconsequential as the shock should be sagged. Pics of the fork on the bike and weights coming Axe, sorry for the delay been super busy.

    I'm talking about the Suntour XC-R-LO 24 not about the RST First. Sorry to have the data mixed up.... The Suntour seems to need a higher pressure.

    I'm sorry, my bad. You stated that clearly.

    IF these forks are air/oil you might consider using thinner oil, if that's at all possible.

    What lighter oil does is move the whole response curve down to their weight. Then you should be able to raise the air pressure somewhat and get the fork working more like it was designed.

    The bad news here is the rebound will probably be a little quick unless the forks have an external adjustment for that.

    The RST does have external rebound, so that might be an option. We're pretty happy at the moment though.

    Fork weighs 3.7lbs (~1680g). About a pound less than the POS it replaced. It makes the bike feel light up front, and it actually works! Air spring is tune able to my daughters weight, and with both compression and rebound adjustments it's reasonable tune able.
