i got a radical idea for ya... ditch your bashguard.... i been riding without one for a year hit my fair share of rocks and logs with the ring and it is just fine!
someone gave me the tip when i was originally building my bike... the logic that swayed me was this: most BMXers don't use bashguards and they seem to be able to brutally hit ***** all the time with no ill affects.
you can buy bmx chainring bolts so it'll fit.
and if you do it, you'll save half a pound, and you'll probably never go back to needing one....
hell, you could probably even sell your bashguard to someone else who "needs" it.
