Am restoring an old Dawes Galaxy and considering getting rid of the original 27" wheels (aluminum Weinmann rims) and building up new ones on 700c rims, either using the original hubs (high flange, Sunshine) or maybe shelling out for some new ones (Velo Orange makes a 126mm spaced rear hub that looks nice) or some nice used ones (Campy maybe). Does anyone have strong feelings about the advantages or disadvantages of converting to 700c on an old road bike? Biggest advantage it seems to me would be greater tire selection with 700c, as well as a bit more clearance in the frame to run a slightly wider tire in the rear. Does it change the way the bike rides/feels? The brakes are long enough to reach 700c rims, I'm pretty sure. I suppose an alternative is just getting new 27" rims and rebuilding with those. Any recommendations or thoughts about 27" rims that are available for sale these days would also be appreciated. Thanks!
