wow nice ride!
I love the thin tubing and the braze on front mech. How are the thumbies performing during mtb? I like the old school look of them.
Have fun, Frank
I really like the Thumbies. I have only ridden Gripshift and Rapidfire-type shifters when borrowing a bike or on test rides. My road bike is Campy friction and my old MTB was Suntour thumbshifters, so I am used to feeling
the shift and not just pressing a button and letting the derailleur do the work. I was also concerned about the large front shift on a 2x9 and I liked the idea of being able to trim the front so there is never any chain rub.
All that being said, unless you really have a thing for thumbshifters they may not be that great. They are not any better than other shifters for rear indexed shifting - they definitely work but I that is what I expected of Dura-Ace barcon shifters. I prefer them for the front, but maybe Gripshift works well and can be trimmed as well.
Also, I think many riders might find it strange to roll their thumb over the top of the bar - basically let go of the bar - to shift. I do not even think about because it is what I have always done. I never think about hitting a bump and my hand coming off, I just shift when I need to shift.
FYI, if you are thinking of using them - I did need to locate a non-Rapid Rise rear der for them to work the way I was used to as well. Supposedly 2007 XTR will be available in non-Rapid Rise, so this will not be an issue in the future.
They are light and they will be lighter after I my alloy bolts arrive.
