Stages introduced their own carbon fiber crank arms at Eurobike last year, offering spindles for BB30 (Red22 and Force/Rival) and BB386 Evo (FSA) arms, using separate spindles to retrofit their cranks to those brands’ driveside. Now, they’re offering spindles to fit an OE version of SRAM MTB cranks that are wider than the standard, and a CINCH-style spindle to fit Race Face cranks.
For standard SRAM-equipped bikes, they have a new GXP compatible carbon fiber arm with power meter attached for $629. There’s a version for road and mountain bikes…
As for Boost, you’ll have to check clearance between crank arms and the chainstay since many bike brands are using Boost to spread the stays wider, putting them closer to the cranks. But for standard bikes, you now have another option to match carbon to carbon and add single-leg power measurement. They’re available in 165, 170, 172.5 and 175 mm lengths.
