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.

Tailored Chainstays

Higher

frames require longer chainstays. The result is a much improved climbing

capacity, which is relevant in large frames. After all, the centre of gravity clearly

shifts backwards with a tall rider, specifically at inclinations. Taller riders

also need more space since they usually have longer feet, and for the longer

cranks to avoid touching the chainstays with their heels.

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.

Triple Butted

"Triple

Butted" means triply 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. For best force distribution in the tube "Triple

Butted" tubes are also applied with different wall thicknesses at the ends.

F100mm

The travel of the fork is 100 mm.
