Clean X3 20" Frame

- Clean X3 frame from the prestigious Spanish brand Clean Trials, manufactured under the highest quality standards, with design and great improvements:

  • Integrated bearing installation, without the need to use cups.
  • Offset bottom bracket to minimise frame flexion when pedalling.
  • Enclosed dropouts designed for 12 mm diameter thru axle rear axles.

- 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” integrated headsets.
- The down tube is hydroformed, which allows the tube sections to be optimized in order to achieve the highest strength with minimal weight.
- The head tube has a Clean logo opening that eliminates unnecessary weight.
- Steerer tube designed for use with integrated bearings without the need for cups.
- Each one of the main tubes is gusseted to the head tube in order to increase this critical area’s strength and stiffness.
- 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.
- 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.
- 91 mm 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.
- Integrated Post Mount disc brake mounts on the left dropout, machined in one piece and designed to ensure top strength and durability.
- 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 a place to install the chain tensioner, which is kept in place with a M5x16mm slave bolt.
- Dropouts are spaced at 120 mm and designed for a 12 mm diameter rear thru-axle.
- Note: it does not include an axle insert, headsetbashplate or chain tensioner, available separately.

The 7 Compatibility Keys
Below, you can find the main details you need to consider when installing different components on this frame:

1) Headset. Use an integrated Clean K1 headset, where the bearings are directly inserted into the frame without the need for cups.

2) Bashplate. This frame has 4-bolt bashplate mounts on the bottom bracket shell. Due to the spacing between mounts, it’s compatible with Clean Strong mini-bashplate.

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 requires a double pulley chain tensioner, so it is not compatible with eccentric or other types of chain tensioners. It is compatible with the chain tensioner Clean X2, Clean X2 ProCrewkerz and those of identical dimensions.

6) Rear hub. 

This frame has a dropout spacing of 120 mm, and allows the use of:

  • Rear hub with thru axle, such as the Clean X3 rear hub, by installing the Clean thru axle inserts.


Also, since this frame only has disc brake mounts, the rear hub must have disc brake mounts too.

7) Fork. 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 here.

The steerer tube on your fork must be long enough so that at least 2 mm 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 (125 mm 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 2 mm of it remain above the top bolt of your stem’s steerer tube clamp.
