XTR has always been my favorite, I think it's the best of its class. It is superlight and very efficient. I also love the style.
The innovation of XTR has put it on the top. I replaced my factory front derailleur with Dyna-Sys front derailleur and now the shifting is pretty smooth.
XTR Dyna-Sys Double Front Derailleur FD-M985 is specifically designed for use with Shimano's XTR Race Double Crankset and XTR 10-speed HG-X chain.
