    Bashwich - BBG Bashguards

    Not sure which forum this belongs to but I ride AM so I'll put it here.

    I'm in the process of converting to a 1x setup and am going to use a 32t ring in the middle of my stock crank. That said my plan is to create a "bashwich" - inner and outer bash guards. My question is, for the inner one, what can I use to determine if the inner bash guard will fit without hitting the frame/chainstay?

    Also I'm thinking of a bbg bash guard, but after my experience with homebrewed components...I was wondering what kind of reputation they have?

    BBG is a pretty solid company and product IMHO. Love my setup!! As for testing the inner guide clearance I just went ahead and bought it. For the money it was pretty cheap and paid off big.

    I think the people that have issues with the inner ring hitting the frame are HT riders. I have the same setup and overall pretty dang happy. Only real complaint about the company is you have to pay for shipping on each item...not over all shipping price. Their prices are cheap enough to not bother me though.

    Thanks for the feedback. I agree on the price/value ratio of them as well. I'll be putting this on a trek fuel ex8 from 2008 so I'd still like to confirm it'd fit...$18 bucks is $18 bucks

    God, I hated my bashwich. Worse than useless. The inner ring was so flimsy I could easily deflect it with one finger. So instead of keeping the chain on the ring, it would freely allow the chain to drop off the ring but then hang on for dear life when I tried to get it back on. Single worst component purchase I've ever made.

    I've got nothing against BBG. I used their regular bashguard for 6 months with no problems and recommend it to others. But the bashwich, no thanks.

    I'm trying not to do a chainguide...one of the reasons I went 1x is because of the removal do the front der and how that cleans up the seattube. Since my bike and I are not DHers I don't want an mrp or the expense of one....or some other guide thing clamped to the seat tube (since I don't have isgc mounts).

    More to your point, maybe ill get the 1/8 inner guard instead of the 1/16 if the 1/16 is too flimsy.

    Similar for me. I also have no ISCG and thought a bashwich might be the solution. Not so much. I ended up with an MRP guide and have not dropped a chain since. Couldn't be happier. But, as you say, they ain't cheap.

    I don't remember a choice of thickness for the inner guards. Maybe the 1/8 will work out for you. Good luck whatever you do.

    My bashwhich is a BBG Outer, and an old 34T chainring with the teeth ground off as the inner. The bike is a Chinese carbon 650b conversion. The chainring is a Homebrew 31T custom. As all of these components are 104 BCD, the unit is bound together with extra long chainring nuts and bolts. No problem with chainstay clearance.

    IME the bashwich is much more reliable holding the chain on than any guide I've tried. The parts are bombproof. Only con is not exactly quiet in use.

    Thanks...regardless I might be willing to take the chance on $36 worth of bash guards before I go the mrp route...

    You have to email the owner, Erin Badaracco. $6 shipping covers up to 3 bashguards. I've done this several times and each time he was really cool and helpful. Unfortunately the site isn't set up that way.

    As for bashwich fitting - just draw a line out from your little ring and make sure that there's enough space to match the bashguard. Bashwiches are a little bit shorter so the bashguard absorbs impacts.

    Cool, I have an email in to him for something else so I'll ask about this too. Did he just send you a custom PayPal invoice or something?

    i can fit the inner bbg on my '12 fuel ex 8. and it is not close to the chainstay.

    i didn't go with the bashwich because i would have had to grind on my crank and didn't want to do that.
    replacing the small chainring with the bash would still let the chain fall in between the middle ring and inner bash.
    if you grind the mounting tabs on the crank you can get the bash close enough and that won't happen.

    I thought Erin is a female

    I thought of using a bashwich converting a SS to 1x9, but as mentioned above I had problems because it's a hardtail. Now I'm thinking of using a Hope guide, simpler, less expensive, and less gaudy than an MRP, and it'll work with a bashguard. Something else to consider if the bashwich doesn't work out for you.

    I've thought of these, but aren't they a pain to adjust/align? It just replaces a spacer on the bb right? My thoughts would be that it's difficult to get the bb tight and keep this in the correct position.

    This is my experience with a bb mounted chain tensioner on my SS.

    I had an MRP 1X BB mount before switching to bashwhich. If it took a hard hit, the BB mount could be moved out of position. Which is why MRP came out with a seat tube mount, I suppose, for bikes without ISCG. But that is an expensive component. This is cheaper and foolproof:

    [QUOTE=jbsmith;9896453]What size is that inner chainring?[/QUOTE.]

    Inner bash is 34T ring with teeth ground down. Chainring is 31T custom made by Homebrew. Outer bash is BBG 32T size. The crank is Truvative 1.1, which has no 64 bcd drillings for inner ring, so I had to work around that.

    I used to have a bashwich setup with a blackspire blackguard. I feel like it really needs a roller guide like a blackspire stinger to really be effective in technical terrain.

    I had a solid BBG bashguard and its truly a great product. i hit it against logs, concrete, steel pipes without major damage etc. plus it feels good to support a small company like that. Although, my buddy managed to annihilate his "oval" drilled bbg (i.e. rubbed the chain) but that was from smashing it into a concrete ledge during a failed bunny hop or something.

    Buy a used MRP 1x on Pinkbike for $20 like I did and call it a day. I even use it for DH days. The BB mount version works great when you tighten the BB cup enough. Oh, and the seat tube mount version is for 1x 'cross bikes or mountain bikes with press fit bottom brackets. Weighs a helluva a lot less and is a lot quieter than a bashwich.

    I had this issue. Went to Home Depot and bought some little plastic spacers to put with chainring bolts. This closed the distance and stopped the chain from dropping in that space.

    sorry but i can't figure out what you mean where did you put the spacers?
    i still have the brand new inner bash and wouldn't mind using it. don't need granny around me.

    They would go on the chainring bolt after it goes through. All you need to do it push the ring over a little to take up that void space. I'd go take a picture but I'm not currently using that set up.

    I had the same issue. I'm using a 2011 XT triple and there is just enough space for the chain to wedge between the chainring (middle position) and the inner bash. I purchased metal spacers (1 mm?) from a bike shop and placed them between the crank and the chainring, moving the chainring to the left closer to the inner bash. It's been several months and the chain has not wedged itself or dropped. I'm very pleased.

    Yes the BBG inter bash is flimsy and useless, I had to buy a second one and glued them together to make it strong enough to work.

    Works good with 32 tooth ring but any thing larger 34 or 36 you can still get chain drops over the inter guard.

    Gamut makes some nice chain guides for non-iscg bikes (Gamut USA Store), I am running their P30S on my other bike and works great.

    I think the inner bash is only designed to be a chain retention device. If you compare the diameter of the 32t outer and the inner, you will find the outer is larger. That's the one taking the impact. Although I believe BBG now offers the inner in a 1/8" as well as the original 1/16" thickness.

    You are correct regarding size. I think it's only meant to work with a chainring up to 32t.

    and that doesn't move it enough to drop in between the middle and outer bash?
    i swear i tried that, but maybe my spacer was too large

    I use a BBG bashwich on my Jamis Dragon. I works great. I use a Race Face crank with a 32 t middle ring. That said, a put a BBG bashwich on my wife's 13 inch framed homegrown and it simply didnt work. The chain fell inward many times. For the life of me I can't figure out why.

    I was concerned that might happen when I installed the spacers, but it's been fine. The chainring is pretty close to centered between the two bashguards. There is not enough room on either side for the chain to wedge itself. I did not measure the thickness of the spacer, but it was the thinnest one they have, maybe 1mm?

    From what you describe, your spacer is too thick. Try the next thinner one from your bike shop. Good luck.

    Just a guess, is the chainring as large or larger than the inner bashguard?

    Can I ask a couple of Q's:

    Is the bashwich you guys are talking about just two BBG bashguards on either side of the chainring or is it an actualy product from BBG?

    If it's just two plates, if I'm running a 32t, would i get two plates in size 32 or would they need to be a little larger to hold the chain on?

    When making a 'bashwich' from two plated (bash guards) - do you not just mount both of them plus the chain ring on the same tabs and use washers or similar to create the right amount of clearance between the chainring and the plates on either side?

    How well does this work in preventing the chain coming off ?

    Thanks

    BBG sells different sized guards with different bcd's. For a 32T chainring you would typically install 32T bash with 104 bcd as the outer and a 32T X 64 bcd as inner. Use the same nuts/bolts that fastened the big ring and granny you replaced. No need for bigger bash especially since the inner must be able to clear your drive side chainstay. Your granny was 22 or 24T so in many cases the 32T inner bash won't clear the chainstay. If it does you are golden; the chain will stay on your chainring reliably and cannot fall off inside or out. The only issue is sometimes the bashwhich can be noisy. Mine is.

    Also, my crank is a Truvative 1.1, which has no 64 bcd drilling. So instead of a 32 X 64 bcd inner, I had to use another 32X 104 bcd. In order to install two 104 bcd guards and 32T chainring on 104 bcd spider, long 15mm chainring bolts required.

    I 'wedged' once with my bashwich, and it was not fun. Chain dropped off the inside while pedaling hard downhill in a rocky section, cranks stopped, foot unclipped, foot hit the ground, I did a somersault, then the bike hit me. Luckily, I had a good pair of gloves on and I missed bashing my cabesa (or other boney parts) on the rocks. Probably my fault - I was running the XT middle ring instead of a dedicated single-speed chainring. I've rectified that situation.

    Today, though, dropping off of a bit of a fast hill (no more than 1 foot) and immediately getting back on the cranks, the chain rode up onto the outer bash. Scared me a bit. I can't wait for MRP's AMG to hit retailers - IMO, this bashwich is just not good enough anymore.

    This is my creation. The inner bash is an old 34T ring with the teeth ground down. The outer is the bash that comes with Truvativ 1.1. No spacers. That chain does not pop off the 31T ring either side ever. Don't see how it could

    Looks good!

    Ordering a set of these for my bike. Hoping running the bashwich 32 guards with a 30 ring will keep the chain in place.

    So? It's not meant to take a hit - it's just to keep the chain jumping off to the inside. IMO, they work best with the outer bash being slightly larger so that it takes the impact from things.

    If they make it thicker/larger, it's going to interfere with chainstays even more - the reason some setups won't work with it already.

    I've been using the 32T BBG Basguard/bashwich with my 30T ring for more than half a year. Never lost a chain and never had any problems save for some light rubbing on the bashwich when I'm on the 34t cog.

    Ah, good to know. Which 30T ring did you go with?

    I'm using the Andersen Machining 30T cog. Just had to file a bit on the crank arms and it's been great.

    Nice to see someone else running this setup. I am looking at the anderson and the extralite 30t. Got any pics?

    So, like some others have said the inner BBG (I got the 1/16th thick version) is a bit two flimsy and the chain can (only did it once) wedge between it and the ring.

    So i'm now thinking I'll either get BBG's 1/8 version for the inner or grind down a ring. I'm concerned about clearance on the inner as it realtes to my frame.

    So for those of you that have ground the teeth on an old ring...my inner BCD is 64....where can I get a 64BCD ring that's large enough? I did a quick google search but didn't see much.

    Here's some pictures of the current setup...showing the space between the chain and the inner...and the clearance to the frame.

    I'm trying not to grind my crank down either to move the inner ring closer to the drive ring.

    I bought a second 1/16th inner ring and glued two of them together to make it one stronger inner ring, and its worked great so far.

    Just ordered the bashwich combo from BBG to use with an anderson 30 tooth ring. Any thoughts on adding an additional guide like a stinger?

    Interesting. And you're using a SS chainring too, right? Maybe a thicker inner will do it - a chainring with the teeth ground off will certainly be stiffer that even the outer BBG bash - and there is something undeniably awesome about going ghetto. That said, I've still lost confidence in non-cage retention systems after using the bashwich for well over a year - have am MRP G3 showing up this week. Perhaps the widget might be a bit stiffer though - I was looking at that before going BBG because of cost difference. I should take a photo of what my bashwich looks like now. Both sides are bent to **** (and not from use as a bash, either) - try to straighten it and it doesn't get much better. With the torque we put on the cranks, even if the chain derails toward the thicker outside plate, to me at least, it seems that a wedge can easily occur.

    My setup looked exactly like yours when I first installed it. There is enough room for the chain to wedge between the chainring and the inner bash. You'd have to try to be sure, but I don't think the 1/8" inner bash is going to solve your problem. Yes, it's stiffer, but it won't change the amount of space between the chainring and the inner bash. And you're going to lose another 1/16" of clearance between the bashguard and the chainstay.

    Grinding the crank will solve your problem, but it will permanently modify your crank. Plus, the chain may rub the inner bash when you're in first gear. I picked up a set of spacers from my LBS (~1mm?) and placed them between the chainring and the crank, moving the chainring further inboard (see post #26 in this thread). This closed the gap between the chainring and the inner bash without permanently modifying the crank. It's been several months and I have not had any wedges or drops.

    No not yet...its the stocker that came with the crank. The SS ring hasn't come in yet...but in looking at the one that is on my SS bike, it dosent look like it's going to take up that much (if any) of that extra space).

    Ha...I didn't fully understand your post (even though I read it like 3 times) until just now. So your saying that on your triple crank, you moved the middle ring closer to the inner bash - correct?

    Did you need to get longer bolts? And I'm also assuming I can use nearly any spacer that won't crush, so either the LBS or the LHS (local hardware store ).

    Yes, moved the middle ring closer to the inner bash using the spacers. Sorry if my previous post was not clear.

    I was debating about longer bolts. I did not use them because my spacers were thin and there seemed to be enough engagement of the threads. No problems so far. But that's up to you depending on the spacers you use. And yes, you could use the LHS as well. You just want something of the correct diameter. The LBS was easier, but I'm sure I paid a premium for four little washers.

    I may end up going this route as well. What did you glue them with? I was thinking of JB Weld and scratching up the surface really well - probably more like gouging with a nail to get a good bond.

    I just used a little bit of JB Weld to hold them together, the bolts also going to hold them together. The single 1/16th is just too weak and will bend and there is a chance for chain to get jammed, so get the second one.

    Got my BBG guards and 30T andersen ring installed today. Everything lined up well and didn't need any spacers. Other than a few bolt compatibility issues between the BBG and andersen parts, everything went fine. Now i'm just waiting on the blackspire stinger to show up before taking it for a ride

    I gotta say...

    Early in this thread a poster was pretty loud about the inner 1/16 bash being flimsy. He sounded a bit over the top. I discounted it.

    I bought it anyway. He is right. Doesn't work. First ride, first time pointing my TRc downhill, rough and fast terrain. The chain didn't stay on for a minute. Using a clutch XT and a Bioncon C guide too. Chain dropped, and jammed under the bendy 1/16 inner bash. It continued to do it on fast jumpy bumpy stuff. Broke the C guide too...Oh well.

    MRP guide is on the way. I am going that 1x guide and the clutch XT. I hope that is the ticket.

    I ended up using two inner rings j-b welded together. I had to open up the holes on the inner to fit over my crank bolt mounts so that the whole thing moved closer to the chainring and as a result would clear my frame. Here are some pictures...j-b weld residue looks worse in these pictures than it really does.

    The inner side with larger holes:

    For all you guys complaining about the 1/16" thick one, why don't you just get the 1/8" thick version and be done with it. Add a few thin washers to center the chain ring between the bash guards and it works perfectly. No dropped chains, no wedged chains between the inner bash and chain ring, and no flimsy inner bash. A well setup bashwich and Shadow+ rear derailleur just plain works.

    I was going to do that but I didn't have the clearance so I had to marry two 1/16 versions and widen the holes on the inner. I now effectively have what you recommend.

    Marcus, any update on the Stinger? Does your Butcher have a ISCG mount? I had to get the BB mount one and the chain rubs the mount slightly on the small ring and large rear sprocket. I bent it a little, but it could use a couple mm S bend in it.

    Yes it fits with no mods if you use the 1/16th inch inner guard. However like others I found that too flimsy. So you either need the 1/8th version and bore out the holes to fit over the crank mounting points (don't bore all the way through just 1/16 of an inch) or glue two 1/16th versions together and just bore out one of them.

    This assumes you're using the stock LX crank that came with the ex8.

    Well, the butcher does have ISCG05 mounts, but in my haste I ordered a standard ISCG stinger The stinger did come with an extra wheel so for what little i paid it wasn't worth sending back. I now have the correct one coming and should have it by wednesday and look to get a ride in by thursday, weather permitting.

    I was able to mock up fitment and it looks like I will have the same alignment issue as it seems to be 1-2mm too far outboard. Im not too keen on bending it so I'm going to lathe off some of the wheel and collar to move it inward a bit. I'll take some pics when it starts going together.

    Got it all together and took it out for a ride today. I'm happy to report the bashwich worked great with the stinger. Took it trough some techy rock gardens and some highspeed downhill sections with lots of washboard and chatter. Never dropped a chain.

    I did modify the stinger's roller using my booty-fab skills to move the wheel closer inboard for proper chain alignment.
