Bashwich - BBG Bashguards

[jbsmith]

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.

[Icey101]

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.

[jbsmith]

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?

[Antikid]

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.

What crank do you have?

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:

What size is that inner chainring?

[dwt]

[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.

[Antikid]

What crank do you have?

shimano m552 is the stocker on the fuel ex 8 and i also got the same results when i got a slx crank.

[jetta_mike]

I used to run this Envy inner bash....worked great and gave you the granny option when needed.

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.
