I am thinking of getting some diff cranks, I have now the TryAll front freewheel cranks for the tapered bottom bracket. And now finding that the right side (srocket side) The square hole is now rounding out, So i was looking and found the TryAll Isis front freewheel cranks. i know that i'll have to get a new bottom bracket and that's fine. But since i have not ever ran the ISIS cranks or ISIS bottom bracket, i was looking to see what the pros and cons are.... He is running a rear Chris King with fixed cog on the crank. Oh and i ride MOD Monty xlite and this thread for my Bro. Thanks.
