UDH Hanger
WIN SL mountain bike frames come standard with a UDH hanger.
A unified mounting reference improves shifting precision.
In the event of a collision, the hanger moves backward to absorb the impact, sacrificing itself to protect the expensive rear derailleur and frame.
Universal parts make replacement easy and offer native compatibility with SRAM T-Type shifting.
Available in a variety of colors
