I just got a bike from bikesdirect with an 8spd Shimano Nexus IGH, & I am having trouble getting it properly adjusted.
We have lined up the 2 yellow lines while in 4th gear using the shifting cable. When we shift gears & then come back to 4th, the lines are no longer aligned.
It also is not shifting smoothly. I can turn the shifter & the number changes, but the gear the bike is actually in does not change. If I turn it another 1 or 2 gears on the shifter, it may suddenly shift, skipping several gears. It also will not go into 7th or 8th gear.
Any suggestion on what may be wrong & how to fix it?
