Bikemag.com spotted this 7-speed cassette aboard Stevie Smith’s Devinci at the Fort William World Cup Downhill race this past weekend.

Moving the chain across it is a very short caged XX1-style derailleur with a horizontal parallelogram and the wide/narrow teeth on the pulley wheels. The knuckle’s emblazoned with the Blackbox logo and holds a clutch mechanism. Word is some of the athletes like a full featured wide range cassette, and some just want a wider range between cogs…but fewer of them. No official word from SRAM, but hit the source link for more commentary and quotes.

Is this compatible with my 7spd SunTour thumbies?

it’s basically an XX1 cassette without the 4 largest tooth cogs, so its spaced out from the driveside hub flange. so its a 7 speed cassette with 11 speed spacing

sam hill and aaron gwin were running the same setup.

Reminds me of Jeff Jones’ 6-speed setups.
