D'you reckon you've reached the point where it's starting to pay for itself financially? Would a derailleur set-up still be going strong?
Well you have to relate its cost to the cost of a reasonable standard setup with block, chains, chainrings and derailleurs. I'm sure that it will overtake it if it hasn't done so already but even if it didn't, it is just hugely worth it if you tour.
I remember on the first horrendous day of our Barcelona Lisbon tour (started south of Barca in Tortosa where we went by train) having to do 5,500 ft. and fifty odd miles in the heat, starting at 1.30pm, how I just click click clicked my way up the climbs while my friend Mick ground, crunched and effed his way up them. We are exactly equal athletes, or non-athletes rather, but now I had a batman, name of Rohloff. It was bloody brilliant.
I was cycling in very hilly terrain last week, in the middle of Brittany around Mur-de-Bretagne, le Faouet etc., and it was just a pleasure to ease my way up the hills in exactly the right gear all the way.
