  • So I currently ride a Tarmac in a size 58 (100mm stem), awaiting the delivery of a Cipollini Bond in size 56. Is it likely i will be able to make it fit me with a longer stem? The headtube is pretty tiny. Geos here

    There's only 6.5mm difference in reach, so that's not going to cause any real trouble. 100mm stem on a 58 is verging on short, 110mm on a 56 is right on the #tester_approved 5:1 ratio of frame size to stem length.

  • Will the 6.5mm difference in reach be affected by the different top tube lengths - 560, 582? 6.5+22 = 28.5mm, would that mean a 130mm stem as I have a 100mm stem on the tarmac? Also will the stack height play a part in this?
