I have not yet completely ruled out going with the Gunnar Sport frame. Would use the same build package as I'm working on now. Maybe even go 650C wheels, if they feel there is enough clearance for a crankset with 165mm or 170mm cranks. But 700 would work. I would need to change out the fork for one that has a shorter axle to crown distance.

Would have to switch from disc brakes, but that's no big deal for me. Would still go with mountain bike stem, handlebar, cassette, derailleurs, twistshifters, crankset, etc.

The Sport 540 (54cm) frame has acceptable measurements for me, especially with a slighter smaller wheel.

I've looked at going this way a number of times.

With these cold, cold winter days, there is time to consider several options. This is actually a less expensive route than going with the Rock Tour frame. The Sport w/carbon fork is $950, which is $300 less out of the gate.
