Rim Features


  • This 38mm deep clincher rim is asymmetrical 2.5mm shape where the spoke holes are not centered, but placed out of the middle of this carbon rim, this gives the wheel a more even spoke tension between left and right and therefore a stiffer and longer lasting wheel. Offset rims have advantages with disc wheels and cassette hubs.
  • Wider rim system offers improved aerodynamics, better handling in crosswinds condition and faster riding.
  • U aerodynamic shape makes road tubeless rims lightweight but still stiff, keeping them stable in cross winds condition.
  • Super lightweight, rim constructed with premium Toray T700 & T800 carbon fiber, best strength to weight ratio with no expense spared.
  • Smooth Wall Tec. No folded prepreg during curing, smooth both inside and outside rim wall to reduce potential quality issues.
  • Carbon Strip Reinforcement. Use unique carbon strip to strengthen the spoke tension and stabilize rim structure and reduce the rim weight.
  • Angled spoke holes allows the nipple to pull straight in line with the spoke for reduced stress, this results in fewer broken spokes and nipples.
