Advice From Our Staff:
It’s not cheap, but this is one of our nicest power meters. It is highly accurate, stiff, lightweight, looks amazing and comes with a solid 2-year warranty. You can mount a wide range of both 2x and 1x chainrings to it, from Shimano to Carbon-Ti to ROTOR and more. In addition, with an option to order it with a 24 mm, 30 mm or DUB spindle, you can put it on almost any bike.
Options
Crank Arm:
- LOOK-SRM Carbon – These are the lightest crank arms offered (260 grams). There are two size options: 165/167.5/170 or 170/172.5/175. The crank arms each function in three lengths simply by rotating the Trilobe pedal inserts.
- SRM Carbon Composite – These carbon arms are still very light and stiff, but they weigh a bit more than the LOOK-SRM Carbon at 344 grams per set. However, they are also more affordable.
Lid:
- 9200 Lid – For Shimano 9200 chainrings
- 9100 Lid – For Shimano 9100 chainrings
- Flat Lid – For any other 110×4 chainrings
Spindle:
- 24 MM – For use with 24 mm Shimano bottom brackets.
- 30 MM – For use with 30 mm bottom brackets.
- 29 MM DUB – For use with DUB bottom brackets.
- 24 MM Titanium – For use with 24 mm Shimano bottom brackets (ultra-lightweight)
