Now 15 years ago I toured on a 50,40,24 triple, 13-34 rear,
but now the Rohloff does things so Much Better.


my Brompton has a 2 speed IG cank 54t, '21.6' (as it's a 2,5 reduction gear)

AW3 is used twice, as if a 6 speed ,

Rohloff does that too, with a 7 speed x2, but all in the same case.




in the 80's my AYH trip leader initiation , a fellow brought his TA double 50 28. 13-28 rear from UK,
.. it worked.
