SUNCORD 406 Carbon Wide-Body 4-Spoke Bicycle Wheelset
š„ Designed specifically for wider 406 tires, this SUNCORD carbon 4-spoke wheelset combines aggressive styling, lightweight performance, and improved ride comfort.
With a 42 mm rim depth, 24 mm internal width, and 31 mm external width, the wide-body rim profile provides better tire support and helps improve shock absorption. It gives the wheelset a bold, muscular appearance while keeping the ride comfortable rather than overly stiff.

Compatible Tire Width:
Suitable for 1.25" to 2.1" tires.
Please confirm frame and fork clearance before installation.
ā
Lightweight Construction:

This wide-body version is suitable for the new BIRDY fitted with 1.25" tires.
Compared with the older narrow-rim design, the wide-body 4-spoke wheel offers better aerodynamic performance and improved tire support. The wider rim profile also helps enhance rolling performance, while giving the tire a fuller, more stable shape once installed.

For JAVA NEO fitted with off-road tires, the original front fork E-hook must be replaced with an extended E-hook in order for the bike to fold properly.
The extended E-hook is included free of charge with the wheelset and is not sold separately.
