I cannot decide between an Ultegra or a Ritchey Pro Cross crank. Anyone got any views on these? I know the Ultegra is a good reliable crank but I know little about the Ritchey although I love the looks.

Thanks

You didn't really mention what you are going to use it for (racing, trail riding, road riding, etc), but here's what I know.

The Ultegra crank normally comes with 39/53 chainring combination which can be kinda big for most cross situations, and is really big for trailriding. It can be done, but some smaller rings would probably suit you better. You can get smaller rings (38 small, 46 or 48 big), but that will add another $60-70 to the equation.

The Ritchey crank comes with 38/48 rings for about the same price as a standard Ultegra (~100-115) and uses the same spline pattern as the Ultegra (making BB choice a moot point).

Another option is to find a standard BCD mountain crank (74/110 rings instead of 130 for road). Leave off the small ring for weight savings (or run it for those granny gear situations), and you can get rings as small as 34T and as big as 54T in a 110 BCD. Some great finds can be had on eBay if you're patient.

I'm running an old RSX crank on my bike right now (picked up closeout from Nashbar about a year ago). Double chainring (36/46) w/ 110 BCD. Dimension used (still do?) make a 110 double crank, but I couldn't find it listed on bikeusa.com (the one place that used to carry it). I think it is probably still available through QBP if you check at your LBS.

If the RSX crank interests you, there is one on eBay now. Just do a search for "RSX crank".

No relation to the seller, just passing along the info (hence no url).

You should also check out the TA cranks available on schwab cycles - they have the 110 BCD and smaller rings. I'm thinking about getting a pair for my 'cross rig before next racing season.

Have them both on my road and xc. Never had any others so I can't compare. I've banged and gouged the cross cranks for years w/o problems. I have the older 110 BCD which allows me to run a 34/48 on the xc. Too bad they changed that. I think they are made by Sugino.

One thing about the Ritchey Cranks that I don't like is the way one of the chainring bolts threads directly into the crank arm. I snugged mine up and stripped it. The chainring bolt was so short that it was only contacting 2-3 threads in the crank arm whereas most chainring bolts contact 4-6 threads. I suspect they design them with integrated chainring bolt threads so that they can use less overall mass and keep the weight down. Really, though, it's an irritating problem because if I had just stripped a chainring bolt I could replaced it and I would still be riding the cranks. Mine are in the process of being warranteed.

Otherwise the cranks are great. Consider the Ritcheys, but replace the bolt right away!

I have the cross crank set up too. 38/48 and like the cranks. I have noticed that the crank arms are closer to the chainring than my other cranks and I can't run a mtb derailleur without it rubing on the arm when in the big ring. A non-triple road der works fine.

I also run the AC forged cranks mentioned on 2 mtb bikes and as a SS for the cx occassionally. I love them. Cheap, stiff and light. Use XTR or Ultegra/DA BB. I bought 3 pairs on ebay (new) with spider for average $45 each.
