Clean Street 24" Frame

Clean Trials Street 24" Frame

High-end Clean 24” street trials frame. Designed to offer maximum quality and performance for 24” street bike trials.

- Extensively tested by the Clean Trials team
- Manufactured with high-quality aluminum tubing.
- Tapered head tube, compatible with semi-integrated headsets, with a top diameter of 1 1/8” and a larger 1.5” lower diameter.- The head tube features an opening to reduce unnecessary weight.
- The main tubes are welded to each other and the head tube with reinforcement welding, along with additional bottom plates to ensure maximum stiffness and strength in the front area.
- Threaded bottom bracket shell, 68 mm wide with a 1.37" x 24tpi thread, without bashplate mounts.
- Integrated Post Mount disc brake mounts on the left dropout, for 180 mm brake rotors.
- The dropout integrates a closed mount for a tru-axle and a mount for a double jockey wheel chain tensioner (not included with the frame). This system ensures the wheel is perfectly centered at all times.
- Includes 12 mm tru-axle inserts.
- Note: headset, bashplate, and chain tensioner are not included, available separately.

The 7 Key Compatibility Points

Below are the main details to consider when building up this frame:

- 1) Headset. Since the head tube of this frame is tapered, with a top diameter of 1 1/8" and a lower diameter of 1.5", it is compatible with semi-integrated headsets of 1 1/8" – 1.5".

- 2) Bashplate. This frame does not feature bashplate mounts. Therefore, it is recommended to install a ring-type protector on the crank.

- 3) Bottom Bracket. A standard threaded bottom bracket of 1.37x24T must be used for this frame, so both traditional and BB30 threaded bottom brackets (Clean, Try-All, Hashtagg, Bonz, etc.) can be used.

- 4) Rear Brake. This frame features Post Mount disc brake mounts, so a rear disc brake of this type must be used. Post Mount calipers are those that rest vertically on the mount, instead of laterally (as with IS calipers).

- 5) Chain Tensioner.  A double jockey wheel chain tensioner from Crewkerz, Clean, or one with identical dimensions should be used.

- 6) Rear Hub. This frame has a dropout spacing of 120 mm, and allows for the use of:

• 12 mm tru-axle rear hubs.

- 7) Fork. Since the head tube of this frame is tapered, with a top diameter of 1 1/8” and a lower diameter of 1.5”, it is compatible with tapered forks of 1 1/8” – 1.5”. If you wish to use a standard fork with a 1 1/8” diameter, an adapter ring can be installed on the lower cup.
