If you're into aluminum, you can't ignore Crewkerz!

The new frame comes in polished silver and brings some updates that contribute to stability, durability, and performance.

Here are the innovations/changes compared to previous productions:

- Optimized wall thickness of the frame tubes (The new hydroformed tubes provide a much more dynamic and efficient behavior!)
- Fully integrated headset (The overall height of the steering unit can now be kept up to 9mm lower than before).
- Carbon chain tensioner (With 9 teeth, 50% lighter, less resistance) -Hope Tech 4 brake lever
- Comes with Crewkerz Ultimate 20° stem ex-work
- New artwork
- Now also available with 970mm wheelbase!

By the way: Crewkerz is the only brand which gives a guarantee of one year on frame and fork.

Here a shortcut of the outstanding features which make this bike 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 with 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. Further on the freewheel is interlocked, for easy change.
- Wheels with threw axle: Both wheels are 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.
- Integrated chain tensioner: The chain has always the perfect tension and the wheel is still sitting on the same spot.
- Cause of the perfect construction the Crewkerz Jealousy frame has no need for any gusset.
