650B Rims Technology
- Hookless Rim Technology : Hookless rim technology provides a more consistent carbon fiber structure at the rim wall. This enhances the durability of the rim and increases its impact resistance. It also provides better grip and sidewall support when cornering.
- Smooth Inner Wall: A specific, thinner, high-pressure air bladder is used to control the smoothness of the inner wall, and the inner wall air bladder can be extracted clean at one time without residue, which not only effectively improves the tightness of the carbon fiber yarn, but also makes the spoke cap and the spoke hole more closely combined.
- One-piece Layup Design : An one-piece layup design is used to increase fiber continuity and reduce the number of overlapping seams for better rim dynamic balance.
- Burp Free Technology : When installing the tire, the raised portion reinforces the bead, making it harder to drive into the center channel.
- Asymmetric Rim Profile : The asymmetric rim profile design significantly balances the spoke tension between the drive side and the non-drive side, resulting in a stronger wheel structure that lasts longer.

- Angle Drilling Technology: All spoke hole angles are tailored to the geometry of the hub. This allows the nipple to be pulled in a straight line with the spokes to reduce stress.
