11-Speed Drive Train

The

11-speed drive train is used in the racing bike & MTB area. The cassette has 11 gear

steps instead of the 10-speed cassette. This

primarily permits a finer selection of gears and improves efficiency to warrant

higher power output. 

Press Fit

The

press-fit bearing is pressed into the bottom bracket shell and not screwed, as

would be usual. The resulting force-lock fastens the bearing in the housing.

The press-fit inner bearing increases stiffness of the crank/inner bearing

combination, increasing the bearing's service life at a lower weight.

Double Butted

"Double

Butted" means doubly conified wall thickness areas with a flowing

transfer. The strength is sufficient at the centre of a tube and the tube walls

can be kept thinner there. The tube therefore is lighter but just as stable.

Tapered Steerer

Semi-integrated headsets with an inner diameter of 1 1/8 inch on top and 1.5 inch

at the bottom ensure best riding stability and excellent control head

stiffness. The stiffness of the fork profits from the more voluminous shaft,

and the forces are discharged into the frame better and with less strain on the

material through the higher-volume control tube.

Internal cable routing

Internally placed shifting and brake lines ensure not only a clean and elegant look, but placement through the frame also protects all the important cables effectively against outer influences.
