They only shipped the wrong levers - my fitter tells me that the 40cm bars they do (and did) ship with my LHT are too wide for me - that I "require" 38cm bars and he has already ordered other bars for me.
It is good to know that the "twitchiness" was from the different style of bars, knowing what it is from does help. That means that I will be remaining in the "circle" drive at my favorite park until I can hold something of a reasonable straight line, at least with this bike. I don't think it will take that long - it may take longer to shift properlyIn the meantime I hope to graduate from the park soon with my Trek.
They did tell me at the LBS that there really are no shorter stems than what is on my LHT, so if I am reading you and OakLeaf correctly it is likely a factor of both bars and stem. That is helpful information. It is worth it to get that smooth rideI am looking forward to seeing what that gearing will do with THE hill in the park. Since it is geared to go loaded up a mountain side, it should make that hill much easier
(ok, so I need to force my hands off of the bars to the shifters, but I will get there)
