Short, CNC-machined crank arms for Specialized's lightweight eMTBs with the SL 1.2 motor. They use the same SRAM DUB spline interface as SRAM cranks, so they go on and come off with an 8mm hex like a regular mountain bike crank.

Highlights

  • For the Specialized SL 1.2 motor: Turbo Levo SL Gen 2 (model year 2023 on) and Kenevo SL
  • SRAM DUB spline interface, the same as SRAM cranks
  • Built on 5DEV's CNC-machined R-SPEC Trail Enduro crank
  • Not for the first-generation Turbo Levo SL motor
  • 160 or 165mm, matte black or matte raw

Fitting

Fitting eCranks is a separate workshop service and isn't included in the price. The Tune workshop can fit them to your pedal-assist eBike and confirm your motor first. 5DEV says the stock cranks come off with an 8mm hex and its arms go on the same way as a SRAM crank on a regular MTB. Use a torque wrench and 5DEV's torque spec.

5DEV eCranks by motor

5DEV makes a separate eCrank for each motor interface. Its current eCrank range includes:

  • Shimano EP8 (5DEV says its EP8 cranks also work on EP801): R-SPEC EP8 eCranks and Titanium EP8 eCranks
  • Bosch, TQ, Avinox and the 2025 Specialized Turbo Levo 4: R-SPEC Bosch/TQ/Avinox eCranks and Titanium Bosch/TQ/Avinox eCranks
  • Specialized Turbo Levo and Kenevo, first three generations (Brose motor): Specialized Brose eCranks and Titanium Specialized Brose eCranks
  • Specialized Turbo Levo SL and Kenevo SL (SL 1.2 motor): SL eCranks with the SRAM DUB spline
  • Fazua Ride 60: ETOR eCranks

Options

Every option is the same SL arm; only the crank length and finish change.
