Strummer Integrated Star Ratchet 60T – Latest Generation
Strummer Integrated Star Ratchet 60T comes with the latest materials and a more efficient and modern integrated system design. This system uses 1 spring, so when the freewheel operates, only one side of the mechanism moves. The structure becomes simpler, minimizing unnecessary friction, and is easier to maintain.
With 60 Teeth, engagement feels tighter and more responsive compared to lower tooth counts. Suitable for riders who want more precise power transfer, faster acceleration, and better control in technical riding conditions.
The integrated design also simplifies the installation and removal process of the ratchet, both for mechanics and users who are accustomed to doing their own servicing.
