Glad to hear everyone's positive experience about Jtek - Bought mine from Peter White and it's still sitting in my part box two tandem shops refused to install this summer. They were not convinced. Oh well I'll try it on one of my single bikes. I have three touring bikes - two campy ergo/racing triple 50/40/26 and another 9 speed durace bar ends/110 Sugino AT 48/34/24 - maybe I've been lucky but none have broken on the road with their shifters - I have barrell adjusters on all three to deal with cable strech, I carry spare chain, spokes, and assorted spare parts - but nothing for shifter repairs. That being said I take my bar end equiped bike on my longer un-supported tours - and that just because of all the books I've read say they are more reliable because of fewer moving pieces. Again I haven't experienced any of these failures with ergo shifters.
