Right in the middle of doing this job, my chain tool broke and I couldn’t get it all back together until I got a new one. And a new one was downtown OKC, having to wind our way past a huge construction mess where the bike shop was. So we got back home and I got the chain back on the bike. Then I had to change the routing, so I had to take it back off and put it on differently. Then I had to adjust the cable tension to match the indexing. And then I discovered that the cassette was worn on the two gears I use most.
So I’m waiting until an expected windfall arrives and I’m going to blow about $100 all at once on new parts: cassette, chain and shifters. And they will all match the new standard with Deore parts and 3×9 speed. And if I can still afford it, someday I’m going to get a Deore crankset (pedals and hanger bearings).
Gotta take care of my car, you know?
