Sorry, didn't read your request correctly. I had a good experience with Martin's in Boyertown. They installed the second update kit and figured out what the actual problem with the bike jumping out of gear was caused by (bad sentence structure....). Manayunk only threw parts at the problem and failed to install a significant portion of the update kit, even though they charged me the full hours for the install and the bike came back after 2 1/2 months in their shop with the same identical problem as it went in with. Supposedly they had their top mechanic work on my bike...I wouldn't recommend them under any circumstances.
