Wheel Split

A corratec bike with Wheel Size Split performes a lot better in flowy trails which have a lot of turns. It is far easier to lay the bike over into the turns, there is more room to move around on the bike and the acceleration out of slow speed turns and situations is great. The smaller rear wheel is marginally more agile and precise on technical trails. On bigger jumps the 27.5 rear wheel gives a little more clearance and there is less risk of the mid air butt buzzing which is heavily unsettling. By the way a unique point of the wheel size split: The 27,5 bike also manuals a lot easier, picking the wheel up and holding it into a manual is easier than with a 29″ rear wheel.

INTERNAL CABLE ROUTING

Shadow Edge Tube 3.0

New generation of the most stable and safest corratec E-bike frame

The bioinic structure of the battery cover provides superior grip when removing the battery. The lid, which is fully integrated into the frame, impresses with its flowing lines and ensures a clean look. The special designed ventilation slots provide the strong Bosch engine with sufficient fresh air and prevent it from overheating. This way the engine ensures maximum powert at any time. In order to increase the torsional rigidity of the down tube an additional bar has been integrated inside the frame. This feature ensures maximum control and safety, even on difficult trails. The locking mechanism, specially developed for the Shadow Edge Tube 3.0, reduces the cutout of the down tube thanks to its smart mounting and thus increases the torsional stiffness of the frame. The double safety locks the battery firmly in the slot and prevents it from rattling or loosening while riding.

650B Wheel Size

650B wheel Size is the new MTB standard. The 650B wheel is not a compromise between 26“ and 29“. It combines the advantages of 26-inch models (weight, torsional stiffness and agility) with the advantages of the 29“ impeller (increased smoothness, rollover behavior, increased cornering stability).

29" Wheel Size

Large wheels roll better. 29 inches require about eight percent less energy than the 26-inch version. The 29“ wheel takes longer to get going, but rolls easily and quickly over rocks and roots, which brings an additional advantage – more comfort.

Larger wheels roll over obstacles more easily. The ability of a wheel to roll over obstacles is proportional to its size. A 29" wheel, which is about 10% larger than a 26" wheel, can roll over 10% larger obstacles. The larger diameter wheels have more angular momentum so they lose less speed to obstacles and rough sections.

29" bikes tend to offer taller riders a more "natural" frame geometry.  

THROUGH AXLE

Through-axles have the advantage that they are larger in diameter than conventional 9 mm axles and thus are significantly stiffer.
