Crewkerz Desire 20" Frame

The new version of the Crewkerz Desire 20" frame is ideal for those looking for a mid-range bike trials frame. Designed to be durable, it now uses a 12 mm tru-axle and features modern competition geometry.
It has been improved several times since its first version in 2018, ensuring reliable performance in Bike Trials.

Description and materials
- Made from 6061-T6 aluminium alloy, with 7075-T6 machining in order to achieve the perfect balance between low weight and high strength.
- 1 1/8” – 1.5” tapered, 125 mm long head tube, with multiple holes that help remove any excess material.
- The main tubes are joined to the headtube by two gussets that ensure higher strength and stiffness.
- Standard 68 mm bottom bracket tube, designed to use threaded bottom brackets with standard 1.37”x24tpi thread.
- It features mounts for a 4-bolt mini bashplate on the bottom bracket shell, compatible with the Crewkerz, Clean bashplate, and all other bashplates with similar dimensions.
- Curved seat stays help increase tyre clearance and also increase rear end’s stiffness.
- The chain stays are joined together with a little tube close to the BB tube, which increases rear end’s strength and stiffness considerably and also prevents it from cracking.
- Features Post Mount disc brake mounts, integrated with the left dropout and reinforced.
The right dropout is machined in one piece that also includes chain tensioner mounts for Crewkerz, Clean or similar sprung tensioners (chain tensioner not included).
- Dropouts are spaced at 135 mm and designed for a 12 mm diameter rear thru-axle.
- Available in anodized black, with Crewkerz Desire graphics in white and red.

The 7 Compatibility Keys
Below you can find the main details you need to consider when building the bike around this frame:
- 1) Headset. This frame uses a semi-integrated, tapered design headset (1 1/8’’ - 1.5’’), like the Crewkerz WAW, Clean …

- 2) Bashplate. This frame has 4-bolt bashplate mounts on the bottom bracket shell. Due to the spacing between mounts, it’s compatible with Crewkerz, Clean bashplate, and all other bashplates with similar dimensions.

- 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 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 mounts for double-wheel chain tensioners from Crewkerz, Clean, and other brands, so additional tensioners aren't needed.

- 6) Rear hub. A 12 mm thru-axle rear hub with 135 mm spacing must be used. In case you’d like to install a hub with 129 mm spacing, you’d need to add a pair of 3mm spacers.
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 catalogue 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.
