Ozonys Curve Short 26" Frame

Ozonys Curve Short 26" Frame

The main innovations of the new Trials frame Ozonys Curve Short 2025 are as follows:

• Updated geometry with more compact wheelbase lengths (1045 mm and 1055 mm), offering greater agility and control while maintaining the same hand position thanks to the optimised head tube angle.
  
  
• New yoke design (bridge connecting the bottom bracket to the rear stays), based on the Crewkerz model, for enhanced reactivity.
  
  
• Updated head tube, inspired by the Crewkerz Ultimate 2025.

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 integrated, tapered design headset (1 1/8’’ - 1.5’’), like the Crewkerz Integrated Headset 1 1/8" - 1.5", 
Clean K1.2 Integrated Headset 1 1/8" - 1.5"..

- 2) Bashplate. This frame does not have any bashplate mounts. Therefore, installing a bashring is recommended.

- 3) Bottom Bracket. Compatible with 91 mm wide AS30 BBs like Crewkerz’s or Clean’s Press Fit 3P crankset.

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

- 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 3 mm 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 26" 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 (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.
