Have the J-tek shifter & Nexus red band on my BF NWT commuter with Salsa short & shallow handlebar - it all works well and has been reliable. Suggest installing a barrel adjuster on the shift cable to help take up the slack from cable stretching [it was a few hundred km before the stretching stopped] - this will help keep the hub's "green dots" properly aligned. Have about 2000 km of all weather commuting on the hub - no problems.
