Here comes the new Clean K1 in World Cup Edition
2017 Clean released the first carbon trialbike.
There were many doubter, if carbon works as frame material in trials.
Today nobody has any more doubts, that carbon frames are also the future in trials.
It is well known, that carbon is much more lighter than aluminium, but also the stiffness and strength of carbon is unsurpassed.
And yes, a carbon frame can also be repaired for an affordable price.
Here the differencies to the K1 model:
-Handlebar and stem from one single piece of carbon “Combo”
-New Clean Pro rims, ultralight and super stable
-Jockey wheels of aluminium with 10 tooth
-Aero flat spokes, lighter and increased security agains spoke break
-brake hose guiding threw seat stay and top tube with rubber sleeve at the head tube discharge point

-Frame, fork and handlebar/stem build of High Modulus Carbon
-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.
-freewheel and sprocket is interlocked, for easy change.
-Integrated chain tensioner: The requirement for vertical dropouts. The chain has always the perfect tension.
-Thru axles in front and rear for maximum stiffness. The wheel is still sitting on the same spot.
We strictly recommend the use of the Clean K1 frame protectors!
