Amazing contribution to cyclists.
I'm with you there, Ian: Herr Rohloff's design and product has greatly improved my Life On Two Wheels.
As for the Speedhub's limitations, it's horses for courses, I guess: The first really good bike I bought was a nice ti-framed light touring Eclipse, purchased in 2002/03. My frustration with the gearing (it had a T105 grupo) reached a figurative tipping point 3/4 of the way up the Foymount hill (12%) in the Madawaska Hills NW of Ottawa in late summer 2013, when I
just could not get bottom gear on my 12-36 rear cog-mit-24T low front ring.
Too much is enuf, sez I, and when I got home I followed up on a ref I'd heard to Rohloff hubs, and that in turn led me to Thorn Cycles and this forum. The rest is a much more cheerful and relaxed history of the last eight or nine years
I finally did sort out the gearing on the Eclipse, in 2018-19. I then enjoyed a couple of years of trouble-free day rides before selling the bike last year to part-finance my Mercury.
On the ref above to Rohloff service in Canada:
I've had only some slightly-less-than-routine issues to deal with (unable to remove my Raven's rear sprocket in order to flip same, in 2017.) But, Alan Wu of Spoke Wrench Cycles in Toronto was able to sort that out with no difficulty at all. Here's his contact info
