Bye bye, ring ring

To somewhere in town, 30 km. When I cleaned my chain two weeks ago, I knew it was a goner. At the bike shop today, bike shop man says "confirmed, gone case". He shows me how shot the transmission is, even replicating chain suck. I replace the casette, chain, and the big and middle chain rings; XT for everything. It takes some doing, but the XT rings eventually fit the LX crankset. Brake cables fixed; they are now silky smooth. The transmission sounds different, but seems finely tuned the first time round. What joy it is to ride a system that's in harmony. Still, that's a feeling. Time will tell tomorrow, with data as hard as a stopwatch.
