I want to convert my singlespeed Fuji Track to use a new, high quality internal gear hub. The frame is steel and has a rear dropout spacing of 120 mm. I want to use normal (dual-pivot) brakes. I'd like to use a bar-end shifter, if possible. It looks like my choices (from www.hubgear.net/table.html) are:
1. Sturmey Archer SRF3 (118.9 mm OLD)
2. SRAM Spectro T3 (117 mm OLD)
3. Sturmey Archer XRF5 (119.7 mm OLD)
Am I am missing any possible choices? Which of these is considered the highest quality?
