I have a 2006 Lemond Reno I received as a project. It had the original components without wheels. I put on Velomax wheels. It does not shift well in the rear. It has Tiagra ST-4400 9 speed shifter, 105 RD-5501 long cage rear derailleur, 9 speed Ultegra CS-6500 12 – 25 cassette, and what I believe is a 9 speed chain. New cables and housing. When shifting from the small sprocket, when it gets to #6 it will skip to #7. No amount of adjustment on the derailleur barrel adjuster solves shifting issues one way or the other. Adjustment can solve that issue, but then it just makes shifting issues on other gears. Derailleur and chain hanger do not appear bent. I’m stumped. Any Ideas? Thank you.
