Clean K1.2 Carbon 26 Frame

Description and materials
- Clean K1.2 26” carbon frame, the evolution of the pioneering Clean K1 26” frame, designed and improved in Spain by Clean Trials.
- Developed by UCI World Champion Abel Mustieles.
- The main update comes from the 4-bolt rim brake mounts, now relocated over the seat stays to improve braking performance in respect to its predecessor, the Clean K1 26”.
- New dropouts spaced at 120mm, compatible with traditional and through-axle rear hubs by exchanging Clean’s hub inserts, available here.
- New graphics, with the outer layer featuring a 12K carbon finish.
- Made of high-modulus, ultralight carbon fibre: frame weighs just 1080g!
- Features a 120mm-long tapered headtube, for 1 1/8” – 1,5” tapered headsets.
- Twin seat-tube design, shaped like a triangle to increase strength and stiffness.
- The sprung chain tensioner mount is integrated onto the right dropout.

- Two pairs of dropout inserts, should you prefer to use a through-axle or a standard hub:
· 1x Pair of dropout inserts for a 12mm through axle.
· 1x Pair of dropout inserts for a standard hub.
- Does not include a headset, chain tensioner nor any other accessories, available separately at our website.

The 7 Compatibility Keys
Below you can find the main details you need to consider when installing different components on this frame:
- 1) Headset. Since the headtube on this frame is tapered, with 1 1/8” top and 1,5” bottom diameters, it’s compatible with 1 1/8” – 1,5” tapered forks. If you’d like to use a standard 1 1/8” diameter fork, you can install an adaptor for the bottom cup, as in the one supplied with Clean’s 1 1/8” – 1,5” tapered headset, available on our catalogue.
- 2) Bashplate. This frame, just like most 26” frames, doesn’t feature any bashplate mounts. You can install a bashring between the crank and freewheel instead, as those available at our website.
- 3) Bottom Bracket. A Press Fit AS30 bottom bracket must be used, like Clean’s X2 crankset.
- 4) Chain tensioner. This frame requires a sprung chain tensioner, so other additional tensioners aren’t needed. It’s compatible with chain tensioners like Clean’s X2, Clean X2 Pro, Crewkerz and those with identical dimensions.
- 5) Rear hub. This frame has rear dropout spacing of 120mm, and is designed to fit:
· A through-axle rear hub, like Clean’s X3 rear hub, by installing Clean’s through-axle inserts.
· A standard rear hub, by installing Clean’s standard hub inserts.
Also, since this frame only has disc brake mounts, the rear hub must feature disc brake mounts too.
- 6) Fork. The steerer tube on your fork must be long enough so that at least 2mm of it remain above the top bolt of your stem’s steerer tube clamp.
To ensure this, you must add the length of the headtube (120mm for this frame), plus the cups bits that sit outside the headtube, plus the headset spacers (if any) and/or dust cover sitting under the stem, plus the length of your stem’s steerer tube clamp. Once you’ve done this, you’ll be ready to know if your fork is long enough so that at least 2mm of it remain above the top bolt of your stem’s steerer tube clamp.
