Quarq’s road-power meter range extends to five crank-based units, with two further retro-fittable spider options. Beneath the range-topping Shimano four-bolt ring-compatible Elsa RS model are SRAM Red, Elsa R, and Riken R options. All of these share stiff and light carbon cranks, which limits their starting price, but the new forged aluminium Riken AL has changed that.
- Highs: Tough, robust and reliable performance
- Lows: Forged alloy is a bit heavy
The Riken AL is available in 130 BCD (bolt circle diameter) or 110 BCD sizes. It doesn’t come with chainrings, but accepts 10-speed Shimano numbers, and many other 10- or 11-speed rings – so you may be able to continue with those you already have. There are 24mm GXP and 30mm BB30 axle options too, with the latter costing a little extra.

The Riken AL is available in 130 BCD or 110 BCD sizes
We tested a Riken AL with GXP axle, 175mm cranks and 110 BCD, and fitted a single 38t SRAM X-Sync ring, but it’ll run two rings as well. The cranks, axle, spider and all hardware weigh 854g, or 924g including the ring, just 159g heavier than the carbon Riken R in 130 BCD format.
The weight difference between the Riken AL and SRAM’s non-power meter, carbon Force 1 crank in equivalent 1x setup is around 250g. But, the increased durability, scratch resistance and probable longevity of alloy evens things out.
