Short story: I'm currently in the market for a new frame because mine is too small.
I own an awesome wheelset - Mavic A319s with 32 spokes to a Shimano 3N80 dyno hub in the front, 105 hub with 36 spokes in the back. I'd like to keep it if at all possible.
After shopping around a bit, I *love* the fit of the 62cm Trek 1.x and 2.x series. Suckers are like a glove. I'm pretty sure my wheelset won't fit though... the rims are 25mm wide, and take a minimum of 28mm tire. Currently I'm using 28mm Conti Gatorskins. I'm planning on taking the wheelset to the store tomorrow to find out for sure.
If they don't, I'm torn between some options:
A - Get a Trek 1.x or 2.x anyways for the fit, and have the wheelset laced to rims that do fit. I'm reluctant to go with skinny tires... not because I don't like them, but because I don't have enough experience to know if I'd hate them toward the end of a long ride. Would they be too harsh for me personally? Not sure. They seem OK on a short test ride. Not worse, just different.
B - The Trek store suggested considering getting the Trek Ion (cyclocross) frameset instead. Naturally, they don't have one in my size built. This frame would have 6mm less BB drop, a 72 head angle instead of 73.9, longer wheelbase, etc. Other than the obvious road vs cx geometry differences in ride feel, the actual stack and reach, thus fit, would be nearly the same. Within 5mm. Not sure if I want this kinda ride, or a road feel. My current frame is a cyclocross with a 72 head angle. It's extremely stable to the point where I feel there is understeer on fast descents.
C - Get some other frame. I'd really hate to do this as I really want to test ride first. It's nearly impossible to find frames in my size built at stores to test ride. I *think* the reason I like the Treks so much is that they have a long 600mm top tube combined with a tall head tube (240mm on the 62cm) to match. I'm guessing the 60cm Salsa Casseroll would work. It has the same 600mm top tube. The head tube is 210, but likely the axle to crown distance is longer also because of the increased tire clearance. There's no dealers near me though, and I'd be buying it blind. That makes me VERY nervous as I can't handle another ill fitting bike.
Any advice / suggestions? Recommendations for a rim replacement with the same ERD as the A319 so I could reuse spokes? Right now I'm leaning toward buying a Trek, stripping it down to the frame, ebaying the components, then moving my current mostly Ultegra stuff over.
