Security policy

Here a shortcut of the outstanding features which make this frame to one of the best on the market:

Tapered Headtube (cone shaped): The bottom bearing has 1.5” to make this sensible are more stable and stiff.
AS30 Crankset: The frame has a big bottom bracket shell with 46mm diameter for press fit bearings, so it is possible to use a 30mm axle. This crankset forms almost a unit with the frame. Every pedal impulse is transferred precisely to the bike.
Threw axle: The rear wheel is fixed with a threw axle directly into the frame and fork. This results not only in high stiffness, but also mounting and demounting process occurs very quickly and the position of the disc to the brake caliper is every time exactly the same.
Integrated chain tensioner: The chain has always the perfect tension and the wheel is still sitting on the same spot. (Chain tensioner is not part of supply).
Cause of the perfect construction the Crewkerz Jealousy frame has no need for any gusset.
