  • No, you don't need 52 or more. No tourist ever needs 50-11, not even in a bunch going 50-55 km/hr. But the problem is the 34. There is more than flat and bergs, you have lots of parts around 2-5% and on those nor the 34, nor the 50 give a good chain line.

  • I agree! 36 works for me, but will still be interesting to compare the three different gearing approaches on the day.

    @modan took some snaps of this rear deraileur in the extreme positions to check that nothing rubs on anything else. Thankfully Jim at BC is a wizard and got it just right
