Description and materials
- New edition of the revolutionary Clean X2 20” frame, now featuring multiple updates.
- The main modifications have been carried out at the front of the bike:
     · The down tube is completely new, and it’s been hydroformed, which allows the tube sections to be optimized in order to achieve the highest strength with minimal weight.
         · The head tube has a new design with different thicknesses that make it stronger but also lighter!
- Made from 6061-T6 aluminium alloy, with 7075-T6 machining in order to achieve the perfect balance between low weight and high strength.
- Features a tapered headtube, for 1 1/8” – 1,5” tapered headsets.
- Each main tube is gusseted to the head tube in order to increase this critical area’s strength and stiffness.
- The down tube joins the bottom bracket shell asymmetrically: instead of joining it at its centre, the BB shell is offset to the left. This allows for minimized frame flexion when pedaling, since the freewheel is now closer to the main tube.
- 91mm wide, threadless bottom bracket shell, designed to use a Press Fit BB30 bottom bracket (won’t fit other systems) and with mini-bashplate mounts for the new 2-piece Clean mini bashplate.
- Features 2 seat tubes instead of one, shaped like a triangle to increase strength and stiffness considerably.
- The seat stays are joined to the top tube with a gusset, similar to a brake booster, essential to avoid rear-end flexion.
- Contoured chain and seat stays provide extra clearance to prevent tyre or crank rubbing.
- The chain stays are joined together with a reinforcement tube that increases this area’s stiffness.
- Integrated Post Mount disc brake mounts on the left dropout, machined in one piece and designed so that the caliper is protected by both stays.
- Features vertical dropouts and uses a double-wheel sprung tensioner (not included with the frame). Thanks to this system, the wheel is always placed in the exact same position.
- With the double-wheel tensioner, you can adjust the chain tension directly and instantly, without needing to loosen the hub bolts or moving the wheel.
- The inner sides of the dropouts have large machined pockets that remove unnecessary material to save some weight.
- The right dropout has an space to install the chain tensioner, which is kept in place with an M5x16mm slave bolt.

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 has 4-bolt bashplate mounts on the bottom bracket shell. Due to the spacing between mounts, it’s compatible with the 2-piece Clean Light and Rockman bashplates (or similar ones). Not compatible with bashplates with different dimensions.

3) Bottom Bracket. A Press Fit BB30 threadless bottom bracket must be used. This means the cups are pressed into the BB shell instead of threaded onto it, using reference 6806-2RS bearings, as in the Clean bottom bracket.

4) Rear Brake. This frame has Post Mount rear disc brake mounts, so be sure to use a rear brake of that type. Post Mount brake calipers sit onto the brake mounts, instead of sideways (as is the case on IS calipers).

5) Chain tensioner. This frame features double-wheel chain tensioner mounts, so other additional tensioners aren’t needed.

6) Rear hub. Since this frame features double-wheel chain tensioner mounts, a 116mm wide rear hub must be used. In case you’d like to install a rear hub with 110mm spacing (common in most 20” bikes that use snail cams), then you must add 3mm spacers to each side of the hub, in order to result in the total of 116mm this frame requires.
Also, since this frame only has disc brake mounts, the rear hub must feature disc brake mounts too.

7) 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 (125mm 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.
