Is that going to look stupid? Is it unnecessary? I'm doing it whatever you say as the rims have been in my shed for years, I'm just interested what your opinions are.
Bikes are
modular. When I need to replace a part, I could get something that matches, or I can instead buy the very best-quality replacement within my budget. Aesthetics are not completely disregarded, but functionality is more important.
Surprisingly my rims actually match, but hubs don't; the spokes are different colours front & back. The drive-train features Ultegra BB, 105 chainset, and three levels of Campagnolo components for the mechs & shifters. Oh, KMC chain and
Ribble brakes.
Some may regard this with horror but its worked beautifully as a utility bike, a year-round commuter, and recently on Ride London at an average speed just shy of 19mph. I see no problem.
