Clean X1 26'' Frame

Clean X1 26'' Frame

- Clean X1 26" bike trials frame from the prestigious Spanish brand Clean Trials, optimised to improve resistance and reliability and introducing some spectacular new finishes.
- 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 headtube has two large holes that remove unnecessary material.
- Each one of the main tubes is gusseted to the head tube in order to increase this critical area’s strength and stiffness.
- Threaded 68 mm wide BB tube, without bashplate.
- 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 frame incorporates rim brake mounts, machined from a single piece of CNC machining.
- 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.
- Both dropouts are open, with 116 mm spacing, and designed for standard hubs.
- Note: it does not include an axle insert, headset, bashplate 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. 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. As usual on most 26” frames, this frame doesn’t have bashplate mounts. Therefore, a bashring must be used to protect the freewheel, like the ones you can find in this section.

- 3) Bottom Bracket. A threaded BB with standard 1.37”x24tpi thread must be used, therefore any traditional or BB30 threaded BBs can be used (Try-All, Hashtagg, etc.).

In order to prevent the cranks from rubbing the seat stays, which may happen due to varying crank offsets for each model, it’s recommended to install a 127,5 mm or 128 mm wide bottom bracket.

- 4) Rear Brake. This frame has 4-bolt rim brake mounts, so be sure to use a rear rim brake of that type. The spacing between bolts holes is 100 mm.

- 5) Chain tensioner. A Crewkerz, Clean or similar sprung tensioner must be used.

- 6) Rear hub. Since this frame is designed for use with snail cams, the rear hub plus the 2 snail cams width must add up to 116 mm.

- 7) Fork. 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 (120 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.
