Pros / Cons
Pros
- Torque sensor, smoother and better cooled than the TSDZ2 according to a review.
- Fits BSA bottom brackets of 68 or 73 mm.
Cons
- Rated 500/750 W, so not pedelec-conform.
- Original firmware offers fewer settings than the open-source TSDZ2 firmware.
- Retailer figures for power (250 W rated, 1200 W peak) and torque partly contradict each other.
