Technology:

Double Time™:
This straight 4-jack design gives a chainring with 26 teeth 52 contact points. The result: a smooth 6.9 degree movement without reducing tooth size or offsetting internal geometry - for enormously high long-term durability.

Seeker™:
The flanges are 3D forged and machined for maximum strength and low weight. Since they are bent in the direction of the rim, the tensioned spokes are already completely correctly aligned. The result: fewer damaged spoke heads and better overall durability.

Side Swap™:
Switching the axes has never been so easy. Side caps without thread can be mounted and swapped out by hand and without tools. The symmetrical Side Swap™ side caps can be mounted on both sides. The left side cap is identical to the right one - so you don't have to check which cap belongs where.

Speedball™:
Only necessary settings have already been made at the factory. Every part of the ball bearing comes from exactly the same supplier, i.e. every bearing bore can be precisely matched to the raceway. With such a small tolerance range, the days where the clearance had to be adjusted after every ride are over.

Torque Caps:
Torque Caps strengthen the connection between the hub and the fork dropout by increasing the surface area that connects both. This creates a stronger and stiffer interface that provides better feedback and more control. This allows you to concentrate on the most important connection: The one between your bike and the trail.
