This is Sabine’s lugged commuter/tourer. It’s one of my favorite bikes. Lovely long point lugs, exquisite candy, 11 speed Ultegra on King wheels… delicious.
And here are some shots of just the frame set:
I also modified a Rivendell Atlantis for a Rohloff hub. David had been running the hub for years, but awkwardly; I cleaned up the install a bit, with long Campy dropouts to allow for chain tensioning, a tab on the chainstay for the Rohloff cable stop, new dropouts for the SON SL generator hub, and internal wiring. On a custom install we’d be able to avoid the torque arm with sliding dropouts, but we wanted to keep the Rivendell look so we compromised and moved the cable routing from the top tube/canti post to down tube/chainstay:
I was also reminded why we love steel. You’d think it would be self evident – we spend lots of time restoring old bikes, from a 1895 Rudge to a 1950’s Thanet to any number of 70’s and 80’s Italian steeds – but riding at Battenkill last weekend, I got a stick in the derailleur:
Note the screen shots from my Gopro below; after wrestling the derailleur out of the wheel, you can see how the cage is nearly vertical, ABOVE the axle. Then, I muscled it considerably to make it more or less in plane with the cassette. The cage was so crushed that the idler pulleys were fouled, but it shifted a little in back and the front der shifted fine. I was most lucky in that the chain wasn’t compromised, and was able to make it the 4 miles back to our car. Even with a replaceable der hanger, on an AL or carbon bike I’d be walking.
But once back to the shop, a dummy axle and hanger alignment tool made it all better.
A new derailleur and all is right with the world.
