"The 33"-Road Bike Racing - compact cranks -two questions

1: theres no prohibition in ACA racing against compacts is here? theres acouple of HCs here that i feel more comfortable doing with a 34...

2: can i swap between a compact anda fullsize without swapping out my chain?

I fixed the spelling in your title (compct). If I'm presumptuous let me know and I'll put it back.

No prohibition that I know of and the chain might have to be shortened a few links.

Others will be more precise.

Yes and yes.

You're better off swapping your cassettes though. It's much less of a hassle than adjusting the FD.

thanks for the fix

i am both dyslexic and typing from a wireless keyboard that is starting to run out of batteries.

bad combo

what RTC said. You can swap the crank without replacing the chain if you're careful, but you have to raise/lower the front derailluer every time, and then adjust the cable tension appropriately. Which hill climbs do you have in mind? A compact isn't necessary for Evans... it's long, but not particularly steep...39/25 or 27 should get you pretty much anywhere in colorado, especially at race speeds.

Why would there be a prohibition against compacts? How could someone even think that it could be an issue?
