QO Race SL ultralight carbon street bike crankset
Earlier this 12 months, new Spanish part firm QO arose from the minds that based Rotor a few years in the past. And bringing that very same drivetrain expertise, they debuted three light-weight Taiwanese carbon crankarm choices – street, gravel & MTB – with alloy chainrings, spiders & {hardware} machined in Madrid, Spain. Now they add one other new Race SL street crankset, optimized for extra weight financial savings. Their objective was to create a lighter crankset than Campagnolo Tremendous File, Shimano Dura-Ace, or SRAM Purple at aggressive pricing, whereas protecting common full-size chainrings to enhance drivetrain effectivity vs. counting on tiny, inefficient cassette cogs to avoid wasting weight.
The result’s a claimed 510g full crankset with 170mm arms and a 50/34T set of chainrings.
What’s new?
In comparison with the Race crankset which launched in early 2025, this new QO Race SL is claimed to weigh 112g much less. An enormous a part of that financial savings comes from a closely machined 7075 alloy 4x110mm spider and matching chainrings in comparison with the aero spider and strong aero outer chainring of the unique QO Race street cranks. The brand new Race SL chainrings keep on with extra standard cutout chainring shaping, however nonetheless get some aero dimples, after which intricately machined-out pockets on the bottom to avoid wasting weight.
However the rings & spider aren’t the one factor new. It additionally seems just like the carbon arms and alloy axles have been simplified a bit to avoid wasting much more weight. The QO Race SL crankarms bolt onto a regular DUB appropriate spindle, and now function the extra frequent Cinch interface for the spider, or doubtlessly direct mount rings. That does imply that the SL crankarms don’t function the 45-tooth OCP spline that’s on the opposite QO cranks (and Rotor cranks) to permit for locking of oval rings, so you’ll have to use this spider… or probably one of many many Cinch appropriate spiders or direct mount 1x chainrings already accessible in the marketplace.
