Avian CR4 DB
1320 grams for 45MM, balance style.
Paint Free Rim
Same paint free rim like our flagship model. 28mm external width, 21mm internal.
Stable and easy to maintain by changing ratchet ring inside.
Ensuring similar tension of drive and non-drive side for stiffer riding feedback. Spoke is unlikely to loosen in 2:1 system too.
Blade spoke with 28mm rim for better aero performance.
Increase the stiffness and stability by changing spoke length and angle.
No external hole design. The continuous structure make the rim stronger and stiffer. Rim tape is not needed and thus saves another 50 grams in use.
Sapim Secure Lock
Secure Lock nipple prevents the self rotation of spoke in long use. Less likely to loosen and ran-out.
