- Introducing the ultimate competition trials frame - the Clean K1 26"!
- Carbon fibre construction and plenty of advanced features make it stand out from the crowd.
- High modulus carbon fibre is hand laid throughout the frame to ensure it has the maximum strength where it counts, while keeping the overall frame weight low.
- Neat 116mm spaced dropouts are suitable for almost all bolt-in rear trials hubs on the market.
- The K1 uses a sprung tensioner (not supplied with frame) that bolts directly into an alloy carrier within the frame itself, allowing for even and consistent chain tension while always keeping your wheel in the same place!
- Unique to the K1 are it's integrated brake clamps - the frame acts as one half of the clamp, while the custom machined lower half bolts in place with tough M6 bolts.
- These mounts help improve frame and brake stiffness, and removes the stress riser of conventional 4-bolt mounts on the seat stays.
- 105mm brake mount spacing allows the use of the current generation of super wide 26" rear rims.
- Twin seat stays enhance brake performance further, and give more rigidity to the frame overall.
- Internal cable routing help keep the clean lines of the frame going, and reduce the chances of damaging your hoses in the event of a crash.
- A super wide (91mm!) bottom bracket shell helps improve rigidity of the front and rear triangles by reducing the need to bend the ends of the stays/tubes in to meet the BB.
- AS30 Press-Fit BB is compatible with any press-fit BB cups with a 46mm diameter.
- Designed to work perfectly with the Clean 3P BB30 Crankset!
- The lower end of the down tube flares out to match the full width of the BB shell, giving more support at this key area of the frame.
- The top and down tube merge into a large gusset to reinforce the head tube area of the frame.
- Like most modern trials frames, the Clean K1 uses a tapered head tube (120mm long) with an internal headset (see 'Compatibility' section below for more information).
- Satin finish is complimented by striking Clean water transfer graphics.
- Weight: 1.158kg (including brake clamps and tensioner mount)!
