The Top End XLT has been re-designed to be lighter and faster with more control than ever. What's new? 

First off, the frame and fork geometry adjust so that every rider can use a fast and furious trunk-powered position. Control through the turns are even smoother with the new steering dampener. The XLT has newly designed ramped and pinned chain rings for unprecedented ease of shifting. The Top End S crankset incorporates new aluminum crank arms with a re-designed oversized bottom bracket spindle, which reduces weight but maximizes stiffness. 

The 27 speeds operated by Shimano Rapid fire hands-on-shifter/brake delivers smooth, repsonsive shifting and braking right at your fingertips, plus the easy-to-operate, no cable, virtually maintenance free, manual upper derailleur system takes the guess work out of the chain rings
