Compulsive Bicycle Tinkerers Disorder. I've known for some time that I was going to redo the drive train on my recumbent. I've finally decided (I think) what I'm going to do.
My son says he has an Ultegra compact crankset that I can have. I already own a 9-speed 12/34 cassette from a failed project. Hopefully that combination will yield a gear that will get me up Jungs Station hill. Hopefully all that I'll have to buy are 9-speed Dura Ace bar ends, Paul's thumbies and a 9-speed recumbent chain. (Recumbents take a lot of chain.) I may have to do something different with the front derailleur.
Completing the project will also require shortening my steering riser by about 2" and extending it's clamp slot. Hopefully that will lower the handlebars so they aren't so much in my line of sight.
