Clean K1 20” Carbon Fork

Clean K1 20” Carbon Fork

New Clean K1 20” carbon fork, in a new design that, thanks to the aluminium inserts for the dropouts, is compatible with 12 mm through-axles and also with standard front hubs (installing inserts available here).

Description and materials
- New Clean K1 20” carbon fork, specially designed for top-level trials riding.
- Updated design for a better performance and now compatible for both through-axle and standard hubs, simply exchanging the dropouts aluminium inserts.
- Developed and tested for months by Clean team riders Ion Areitio, Dominik Oswald, Sebastián Ruiz, etc.
- Inner structure is made of UD carbon fibre, whereas the outer layer is made of 12K carbon for a more spectacular finish, keeping high strength and stiffness and low weight.
- High modulus mono-block construction, which guarantees better properties than most carbon forks available.
- Features a tapered steerer tube, with 1 1/8” diameter at the top and 1.5” diameter at the bottom, for use with tapered headsets of said diameters.
- Furthermore, the steerer tube is made of carbon fibre and Kevlar, for increased toughness and stiffness, and also features an aluminium insert that erases the need for a star nut.
- 180mm long steerer tube, with integrated crown race system at the base, so you no longer need to install a crown race, since the bearing sits directly onto the fork.
- Features both 4-bolt rim brake mounts and Post Mount disc brake mounts.
- The 4-bolt rim brake mounts are integrated at the back of the legs, spaced at 91 mm.
- 160 mm Post Mount disc brake mount, neatly integrated in the fork leg.
- The dropouts are designed for 12 mm through-axle front hubs.

Includes
- The fork is supplied with aluminium inserts for a 12 mm through-axle front hub.
- Does not include inserts for standard front hubs (available separately here).

Compatibility
- The steerer tube in this fork is tapered, and it has a 1 1/8” diameter at the top and 1.5” diameter at the bottom, so it’s not compatible with those frames that have a standard 1 1/8” steerer tube. A tapered 1 1/8” – 1.5” headset or a headset adaptor must be used to install this fork.
