It took about 20 minutes to re-run cables and get everything adjusted. It was so nice. This thing finally stops the way I want it to. That's a nice feature when you're hauling over 100 lbs. of cargo... or your children :)
While I had it on the work stand, I also took the opportunity to take some slack out of the chain. When I originally installed the IGH, I wanted to leave the ability to shift in the front so I could experiment with gear ratios. After realizing I only needed the middle chainring, I took the front shifter off long ago.
Get out there.
