• Absolutely do it! Whilst my 96 and 94 bikes are 2.8 frames there'll be neglible differences, in fact at the rear I bet you'd get a 33c in there! First image is my 94 R900 with 700x27 Vittoria Pave CG's and the second my old 96 R900 with 700x28 Continental GP5000TL's. Both with modern wide carbon wheelsets.
