Had a quick question concerning mounting a bashguard. Have always wanted to try one so I figured i'd install this cheap one from Nashbar just to give it a shot.

http://www.nashbar.com/bikes//Product_10053_10052_174826_-1___

My question is when it ask's for dimensions for the guard (94mm and 110mm), obviously there is a big difference in size. Is that size the size of the Large chain ring you will be taking off to mount the bashguard or the size of the Middle chain ring you will be mounting it to.

Thanks guys

Neither, it is the 'bolt circle diameter'....or the diameter of the circle the mounting bolts would lye on.

110mm are standard MTB tripple ring 5 bolt cranks. 94mm is used on 5 bolt compact (smaller rings) cranks. 104mm is used on 4 bolt cranks.

BTW, if you want to support a 'little guy', these guys make a great product at a GREAT price: http://www.bbgbashguard.com/

Thanks a lot brother!

That website has some great info on it. Will definatley add to the favorite list. The formula for multiplying your hole distance by to determine you BCD will save a ton of time.

Definately like the look of the bashguards to the link you sent and always like to help out the smaller bike companies. Guarnteed for life is another plus

Thanks again.

That BBG site is great, I got my first one from them last year for only $15 shipped.
I'm getting another one soon for a different bike, I think they're up to like $18 shipped now.
Still way better then spending $40 for one with a big brand name on it.

a lot of bashs need special bolts, or short bolts, or long bolts.. or something weird. i got a raceface because it simply replaces the big ring without changing any bolts.
