Ozonys Curve Hyd V8 20'' Frame

Description and materials
- New evolution of the most emblematic Ozonys frame, the Curve Hyd V8 20”!
- This edition features a totally new rear, featuring new dropouts and chain tensioning system now compatible with a double-wheel tensioner.
- The Post Mount disc brake mount has also been revised, repositioned and reinforced.
- The main tubes thicknesses have been revised in order to increase strength and stiffness even more.
- Keeps the 1 1/8” – 1,5” tapered headtube, introduced on the V7 version, which is joined to the main tube to ensure maximum strength. It’s CNC machined from one piece, 125mm long and features spectacular holes that help remove unnecessary material and give it a cool look.
- Thanks to the hydro-forming technique, which helps improve strength and stiffness while saving weight since less tube length is needed.
- Twin seat-tube design, creating a triangular-shaped structure over the bottom bracket in order to achieve the stiffest tube arrangement possible.
- Contoured seat and chain stays provide more than enough tyre clearance, but also help increase overall strength and stiffness of the rear end of the bike.
- New, CNC-machined vertical dropouts, with large holes that achieve the perfect balance between low weight and high strength.
- Uses a double-wheel sprung tensioner (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.
- Designed to use a 116mm rear hub.
- 160mm Post Mount disc brake mounts, CNC machined from one piece, with a large weld to reinforce this critical area.
- Features 4-bolt mini bashplate mounts on the bottom bracket shell.
- Includes its own Ozonys double-wheel chain tensioner, as well as plastic hose guides.

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. This frame has 4-bolt bashplate mounts on the bottom bracket shell. This means it’s compatible with Bonz Pro Light, Clean Light and those bashplates with the following dimensions:
         · Distance between front and rear holes: 39-40mm.
         · Lateral distance between holes: 43mm.

- 3) Bottom Bracket. A bottom bracket with standard 1.37x24T thread must be used on this frame, therefore you can install conventional and BB30 threaded BB’s (Try-All, Hashtagg, Bonz, etc.). In order to avoid the cranks from rubbing the seat stays, which may happen due to varying crank offsets for each model, it’s recommended to install a 127,5mm or 128mm 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 includes its own double-wheel chain tensioner, so other additional tensioners aren’t needed. Also, it’s compatible with the Clean X2 chain tensioner and those with the same dimensions.

- 6) Rear hub. Since this frame features double-wheel chain tensioner mounts, a 116mm wide rear hub must be used. In case you’d like to install a rear hub with 110mm spacing (common in most 20” bikes that use snail cams), then you must add 3mm spacers to each side of the hub, in order to result in the total of 116mm this frame requires.
Also, since this frame only has disc brake mounts, the rear hub must feature disc brake mounts too.

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