From 3 to 2 on an XC bike

Would it be possible to change from 3 chainrings to 2 on my 29er? I never really use my big chainring, and the extra clearance would help for the multitudes of logs that we have around here. What would it require? I have a bontrager race crank, and i dont know what the chainrings are. Do i have to get a bashguard? if i get a bashguard can i get one that is just a little bit bigger than my 2nd ring? I wanna get a bit more clearance, but i dont wanna spend a whole bunch of money. If i could get away with just taking off one ring, i would.


thanks
harris

If you don't want the bash guard buy some short bolts and just take off the outter ring

Yeah, just remove your big ring, buying a bashguard = optional. Shorter ring bolts are cheap at your LBS.

okay, so i take my big ring off, and get shorter bolts. and readjust the derraileur limits. which one? front or back? im guessing front. I read in MBA that if you remove your big ring, you can take out 4 links in your chain. might this be true?
also, if i were to go with a bash ring, what would you folks suggest?

thanks

You will adjust the outer limit on the front derailleur so you can't shift past the middle ring.

For a bashring, lots of people like the e.thirteen supercharger, but unless you're bombing rockgardens or shorting urban ledges, you may wish to go with somthing a little less, well...imposing. There's a wide variety of sizes and styles. Most shops should be able to get you any of these.
