Hi there.
I have a Dahon MU XL urban commuter bike. I've put perhaps 250 miles on it and really like it. I especially like the Nexus 8 hub: no deraillers, totally clean shifts, shifting while pedaling, shifting while sitting at a stop light.
Anyway, today I did a few tweaks to my bike (pedals, lights, etc). One other thing I did was to change the angle that the brake levers were mounted on the handle bars. The retailer had them too parallel to the ground, so I wanted to rotate them down about 35-degrees. To do so, I also had to loosen the shift lever set (Shimano SL-8s20). All I did was loosen the clamp screw, rotate, and re-tighten. Everything apparently went fine.
But what I now notice is that when I am in the low gears 1-3, and pedal hard from a dead stop, there is a slipping/popping/jumping noise from the hub. It's as if the gears are improperly engaged in the hub, and giving them load, pops them into a different space. For reference I'm 77kg and about 1.8m. It never did this in the past.
I checked the cabling to make sure everything is properly seated (it is). Checked that the cable was kinked or pulled funny or feeding weird (doesn't seem to be). I've made sure the two yellow lines are perfectly aligned during 4th gear by using the adjustment dial on the shift lever set. Regardless, the popping/slipping continues to happen.
This is really annoying me. I loved how bulletproof this hub was, but now it seems to be unhappy and unresponsive to the known adjustments. What should I do ?
Thanks
