Crewkerz Jealousy Ultimate 2024 20" Frame

Crewkerz Jealousy Ultimate 2024 20" Frame

- Crewkerz Jealousy 20” bike trials frame, developed with state-of-the-art technology.
- 100% exclusive design, with every tube and reinforcement optimized for a specific function.
- This frame is a pioneer in introducing the rear thru-axle, an important leap that eases wheel installation and stiffens the frame’s rear end.
- 1 1/8” – 1.5” tapered, 120 mm long head tube, with multiple holes that help remove any excess material.
- The main tubes have variable curvature and thickness in order to achieve minimal weight with the highest strength possible.
- Triangular twin seat tube design, the stiffest possible configuration.
- The left seat tube has a hose guide with bolt on the inside.
- The BB tube is compatible with Press Fit BBs, and it’s welded asymmetrically to the down tube in order to maximize stiffness when pedalling.
- Moreover, it’s integrated into a robust joint with for the chain stays to prevent cracking.
- Does not have any bashplate mounts.
- The seat stays are joined together and to the twin seat tubes, which increases stiffness exponentially.
- Their contoured design optimizes stiffness and allows for enough tyre clearance.
- The right dropout is machined in a very robust 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 2 versions: 970 mm for riders up to 1.60 m and 1005 mm for riders over 1.60 m.

The 7 Compatibility Keys
Below you can find the main details you need to consider when building the bike around this frame:

- 1) Headset. Compatible with Integrated Headset 1 1/8" - 1.5". If you’d like to use a 1 1/8” diameter fork, you must install an adaptor for the bottom cup, available on our website.

- 2) Bashplate. This frame is exclusively compatible with the Crewkerz Mini Bashplate.

- 3) Bottom Bracket. Compatible with AS30 BBs like Crewkerz’s or Clean’s Press Fit 3P crankset.

- 4) Rear Brake. This frame has Disc brake mounts, so be sure to use a rear brake of that type.

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

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

- 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.
