Replacing worn-out chainrings on my SRAM Rival crankset
Seeking to tap the forum's collective wisdom on a repair project..
I've ridden my bike in all conditions-- Rain or shine, plenty of exposure to mud, sand, water spray, etc. After 6000 miles of this kind of abuse, my SRAM Rival crankset's chainrings are inevitably in pretty sad shape, with the "shark's fin" wear pattern pretty evident on the teeth, and the chain-skip symptoms to match.
So it's time for me to swap in some new chainrings and a new chain.
The stock SRAM Rival crankset on my bike is 50/34T with 110mm BCD and 5-bolt pattern. I'm thinking of taking this opportunity to replace the worn-out rings with a 52/36T combination to pick up a bit more speed on downslopes, and I found that FSA has 110mm BCD 5-bolt chainrings available in 52 and 36T (chainrings from FSA's Pro Road series).
My question: Are those FSA Pro Road chainrings compatible with my SRAM Rival crank's spider? And if they are, is it as simple as just bolting the new FSA rings onto the Rival crank's spider using the crank's existing allen-key bolts, or do I need to buy additional hardware?
Thanks for any answers!
