Crankring Help!
I've got a 2011 Cannondale Trail SL4 with an 8 speed Shimano Alivio group with a triple FSA Alfa Drive crank. A while back I took a spill and managed to wedge the chain between the large and middle rings. Apparently I bent the two rings in the process. I've been on the road bike pretty heavily this year and need to get my MTB going again for an upcomming trip.
The FSA has a 42, 32, 22 chainring set. I'm not sure I would not be better off just upgrading the crank instead of trying to replace the chainrings. What is compatible with my setup? My best guess would be any 8-9 speed crank.
Thanks in advance for your help.
