Denver Nexus Guru

I am looking for a knowledgable Shimano Nexus mechanic in the Denver area. Any ideas? My 8 speed Nexus has started skipping/slipping in fourth gear. It sounds and feels a bit like the chain skipping a cog but it is in the hub.

Alas, finding a competent and experienced mechanic is the bane of IG hub users. A few months ago I was considering sending my hub to Harris for an overhaul, but shipping+labor was going to cost as much as a new hub, so in the end I decided to overhaul the hub myself. It was a success, mostly.

A few thoughts:

--Are you quite sure the cable isn't out of adjustment, even a tiny bit?

--I don't know if this applies to the Nexus, but with the Sturmey Archer 8-sp hub, cone adjustment is just as important as cable adjustment. If the cones have loosened a tiny bit, some gears will not register properly.

--The problem could be in the shifter, in which case the solution is a new shifter. I have heard the Nexus-8 twist shifters wear out pretty quick.

My guess is that the shifter cable is just enough out of adjustment (through stretching) to position you between the gears.

Check your cable adjustment per the green area on this sheet...
