FSA releases 2017 MTB component details

Future-proof cranks, Di2-ready bars, wider wheels for 2017

FSA has just released details of its 2017 products. Here are some of the mountain bike components, including future-proof cranks, wider wheels and a dropper seatpost. Read on for the details.

One crankset for all standards

FSA releases their new mountain crank platforms with what they're claiming to be an industry first: a fully modular system featuring a built-in adjustable chainline for Boost and non-Boost configurations. User-interchangeable spindles, spiders and direct mount chainrings ensure compatibility with all current and future standards. Four different crank levels use this technology; the hollow carbon SL-K, hollow 6061 aluminum Afterburner, forged 6061 aluminum V-Drive, and forged 6061 aluminum Comet. 

On the high-end side, fsa's 495g (estimated) sl-k cranks feature hollow carbon arms with a uni-directional carbon finish and are available in 170mm and 175mm lengths:
