I'm getting ready to build a dynamo hub into a wheel. Initially I was going to use a frame that was made for 27", and then, along the way, found a better one, designed for 700c. I have a plethora of 27"rims at the ready. can anybody see any reason to not continue with the 27". the brakes on all of my current fleet have the needed 4mm adjustment available.
As always, thanks in advance.
