Hey I'm new to all this so just bear with me, but I was wondering if most cx cranksets were doubles and not triples?

runs doubles, probably most with a low gear of 38/27. If you need something smaller than that you might as well get off and run as that's going to be faster.
Single ring also an option...iml

usually a 42 or 44. Depends on your intended use of course, but a single ring can be a great racing setup. However, as DB said, a double with a fair range in back is the best for most folks/applications.

Me. 30/40/50 Campy.

Why? Because I like to train on the bike off-road, have the touring option, and whup the ass of MTBers as and when.

Purely for racing - no I wouldn't. But the extra weight really doesn't bother me...

I plan to do a fair bit of off road riding around here with the one other woman that races cyclocross seriously. (ok, there are a few, but we are the only mountain bikers that take/will take our CX bikes off road). I am running a triple XT crankset 22/32/42, XTR front derailleur, and 105 shifter (12-25 road cassette). Since I'm still waiting on a new stem, I have only ridden the bike around the parking lot, but the shifting was great. I will switch out to a double if I have problems with the triple.

So many great ideas, so little money .... I run a double and on some long climbs, I wish I had a triple.

I think you will find that a 42/12 is just not going to be a big enough gear on the road. You will be spinning that gear out, even on slight downgrades.

Just my thoughts. Good luck.

yeah 42/12 is no good on the road. I run a single ring up front but just switch it from 42 to a 48 if I want to do a road ride with the cross bike. The 48 is big enough to go pretty fast with on flats and when going downhill I just coast if its not big enough and with a 27 in back I can climb most hills except the REALLY steep stuff which I avoid on this bike. The 42/27 is pretty good for most fireroads and stuff if I want to ride it off road.

The bike won't be used on the road. Most of the CX courses around here don't have very long road stretches. I have a fairly high cadence (can go up to 125 rpm/min. comfortably thanks to some track work) and don't think I'll have a problem with spinning out during races. I have been racing a mtb for CX for 3 years with a 22/32/42 up front and a 12-34 in the rear. I mostly used the 32 and the middle range of the rear cluster. I'm a spinner, not a masher.

Plus, this bike will be seeing a fair amount of "real" mountain bike work when it's too nasty to get the race mtb icky. We have several 'cross bike friendly' trails in this area as well as a few hundred miles of fireroad in North Georgia.

I think I'll keep my triple :)
