For the past five years I've been riding singlespeed about 95% of the time. I sold off all my geared rides except for the Potts and been satisfied with things as they were. Coming off a winter of next to no riding and a spring that's been pretty much the same, I decided it was time to gear up. An XT/Mavic rear wheel, XT derailleur and cassette and a Dura Ace shifter later, I'm once again amongst the geared. Never one to set my bikes up conventionally, I run BB 7 brakes front and rear, which are finnicky to set up on the slot drop Inbred and require the rear wheel to be set more toward the rear of the drops than front. Okay running SS with a bolt on hub and tuggnuts, not so easy geared with a QR. Due to the brake restrictions, the rear wheel can't be run all the way forward and I need to use the tuggnuts still. Two tuggnuts and a QR make installing and removing the wheel a bit of a pain in the ass (yes, I tried it with one tugg only and the wheel cocked under load) The extra width of the twin tuggies effectively (or ineffectively) shorten the skewer length so that it's threads are not completely engaged by the end cap. I haven't lost my rear wheel yet so it should be okay...I hope!
The pic is worth far more than my babblings.
