Here comes the new Clean K1 in various variants.

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.

You have the choice between:

Disc/HS + Fixed Hub + H/Bar+Stem
Disc/HS + Fixed Hub + Combo
Disc/Disc + Fixed Hub + H/Bar+Stem
Disc/Disc + Fixed Hub + Combo
Disc/HS + Freehub + H/Bar+Stem
Disc/HS + Freehub + Combo
Disc/Disc + Freehub + H/Bar+Stem
Disc/Disc + Freehub + Combo

(The pictures show a model with: Disc/HS + Fixed Hub + Combo)

All bikes come with the ultra-stiff and break-resistant Aero blade spokes as well as the lightweight Pro rims.
The outstanding details:
-Frame and fork build of High Modulus Carbon (also handlebar/stem Combo on option)
-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 (clean Freehub on option)
-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!
