Recreational Cyclocross and Gravelbiking This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like :The Dirty Kanza". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

Crankset recommendations

I'm looking to replace my FSA Gossamer triple crankset with a CX-specific double. I'm looking for something in the $200-ish or less price range. I think I want an external bottom bracket unless someone can convince me I shouldn't want that.

I want this for CX racing, but I'm not particularly fast or powerful, and I'm not entire certain I could really distinguish Shimano Tourney from SRAM Red, but I want something nice. I've got Shimano 10-speed components on the bike right now.

It looks like the leading candidates are:

FSA Omega
FSA Gossamer
FSA Energy
FSA SL-K ($220 on eBay?)
SRAM S300
SRAM Rival
Bontrager Race

The only data I have two distinguish them are price, weight and gearing. I'd like to add your opinions and experiences to that.

I'd like to hear some input on the gearing choices. I like the idea of 46-36 better than 46-38, but I can see the advantages of the latter. I think I'd prefer 110-bcd because it give me the option of throwing on a smaller granny gear for road riding. I'm open to suggestion here.

I'd also like to hear some thoughts on crank length. I have 170mm cranks on all my bikes right now. I've used 175 before on a MTB-ish commuter and 165 on a fixie. I was considering 172.5 but I'm not sure what the advantages are.

So, talk to me.

You may want to add Chris King to your BB list for under two hundred. I use the FSA Energy Compact/Cyclocross (172.5) with the Chris King BB. I believe this to be a reasonably good compromise for road gearing also if you do long distance cycling over hilly routes.

How about something like the TruVativ Elita? I have one on one of my cross bikes and it's pretty nice. I had planned on replacing it when I got the bike with something more flash, but after riding it for awhile, I've come to like it. Not bad looking and you can pick up one with the bottom bracket for around $100.

I've had the Sram S300 crank with 38 & 46t chainrings on my bike for the last 5000 miles. It's been perfect. The chainring range with a 11-25 offers tight spacing from 15 to 33 mph.
