Description and materials
- Kit composed of a Breeth 20” carbon frame, carbon fork, headset and protectors.
- Featuring the new, top-of-the-range Breeth 20” carbon frame and fork, tested and developed for more than a year by Breeth and Breath team rider Zhao Xuan.
- The frame has Post Mount disc brake mounts and the fork comes with both 4-bolt HS rim brake mounts.

Main features of the Breeth Carbon 20" Frame
- This frame is made of ultra-light, high-quality carbon fibre.
- 100% exclusive design by Breeth, with special fibre layers configuration to optimize strength and stiffness in all riding conditions.
- Tapered head tube 1 1/8” top (41.8mm) and 1 3/8” bottom (49mm), 125mm long, for integrated headsets (without cups).
- Over-dimensioned main tubes in order to ensure high strength and stiffness.
- The BB shell features a 68mm-wide threaded aluminium insert, which is compatible with standard 1.37” x 24tpi threaded BBs.
- The frame doesn’t have any bashplate mounts, therefore it’s recommended to install a bashring on the crank.
- The stays have been optimized in design and dimensions to minimize flexion at the back of the frame.
- Features Post Mount disc brake mounts (for 160mm rotor), neatly integrated with the left stay.
- Chain tension can be adjusted via snail cam chain tensioners (not included).
- Horizontal dropouts spaced at 116mm.
- Features a small opening on the main tube and another one on the inside of the left chain stay, which allow the main hose to be internally routed easily.
- Note: this frame is only compatible with the Breeth 20” headset and Breeth Carbon 20” 1 3/8” fork (49mm). In case you’d like to install a 1 1/8” or 1.5” fork, you’d also need to use the corresponding adaptor.

Main features of the Breeth Carbon 20" Fork
- This fork is made of ultra-light, high-quality carbon fibre.
- 100% exclusive mono-block design by Breeth, with special fibre layers configuration to optimize strength and stiffness in all riding conditions.
- 210mm long, tapered steerer tube, 1 1/8” top (41.8mm) and 1 3/8” bottom (49mm).
- Moreover, the steerer tube combines carbon fibre and Kevlar and features a 2.5mm aluminium insert to increase strength.
- This fork comes with both 4-bolt rim brake mounts.
- The 4-bolt rim brake mounts are integrated at the back of the legs and spaced at 88mm.
- The dropouts are designed for 10mm diameter and 100mm wide axles, so most bike trials front hubs are compatible.
- Note: this fork is only compatible with the Breeth Carbon 20” frame and Breeth 20” headset.

The 7 Compatibility Keys
Below you can find the main aspects to consider when building this frame:

- 1) Headset. Compatible with the Breeth Tapered 1 1/8” – 1 3/8” integrated headset, included with this kit, whose dimensions are:
- Top bearing diameter: 1 1/8” (41.8mm)
- Top bearing width: 6.5mm
- Bottom bearing diameter: 1 3/8” (49mm)
- Bottom bearing width: 7mm

- 2) Bashplate. The frame doesn’t have any bashplate mounts, therefore it’s recommended to install a bashring on the crank.
Moreover, it’s highly recommended to install the auto-adhesive carbon protectors supplied with the frame to prevent damage from scratches and impacts.

- 3) Bottom Bracket. A 68mm-wide 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 specific crank offsets for each brand, it’s recommended to install a 127,5mm or 128mm wide bottom bracket.

- 4) Rear Brake. A Post Mount rear disc brake must be used. Post Mount brake calipers sit onto the brake mounts, instead of being bolted sideways (as is the case on IS calipers).

- 5) Chain tensioner. Snail cams must be used.

- 6) Rear hub. 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), then you must add 3mm snail cams 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 the Breeth fork supplied is 210mm long, which is more than enough so that you can cut it down to the desired length. In case you’d like to install a 1 1/8” or 1.5” fork, you’d also need to use the corresponding adaptor.
