M923XC ARCH BRIDGE CARBON RIMS
EXTREMELY LIGHT CROSS COUNTRY Carbon rims w/t Arch Bridge Design
It's as light as a feather, only 320g for the rim!!! But it's strong enough to tackle rocks and roots in your cross country races.
To achieve this goal, our team invented the unique arch bridge design from Chinese ancient stone bridge structure.
