TSDZ2 110BCD Double Chainrings
Increased gear range by having double chainrings on your TSDZ2 mid-drive motor. Made in USA of aircraft grade T6 hardened and anodized aluminum. Choose between two sets of double chainrings depending on whether your primarily ride single-track trails or on the roads. 34/40T for MTB/Trails and 40/50T for Roads. These mount on the stock spider that comes with the motor. The larger chainring replaces the chain-guard ring.
You can use the double rings with a derailleur or just move your chain by hand depending on where you are riding. A smaller chainring is better for hills and single track trails whereas a bigger one is better for riding around town or commuting.
