Changing from 27 inch to 700
I have a bike with 27 x 1 - 1/4 wheels (630 mm). I am considering switching to 700's (at least at the back).
My understanding is that it is not recommended to switch wheel sizes on a frame because brake reach could be come an issue? Are there other pitfalls i could run into?
If i swap the back wheel for a 700 should I also switch the front if I don't what issues will I face? Thanks guys, hope this question made some sense.
