NEW XG-795 X01 DH MINI BLOCK™ 7-speed Cassette
The MINI BLOCK™ X-DOME™ 7-speed cassette is engineered for the optimized gear steps that downhill riders want. Featuring 10–24 gearing with two-tooth steps, this technology eliminates the need for double/triple shifts to get in the gear you want. And because it’s so compact, it’s also light—the lightest cassette in existence. Compatible with any XD wheel, MINI BLOCK™ X-DOME™ technology integrates flawlessly with your SRAM 1X™ drivetrain. With durable JET™ black finish, the cassette looks as tough as it performs—ride after ride.
- Larger jumps between gears eliminate the need for double/triple shifts to get in the gear you want. (10-12-14-16-18-21-24)
- Less cogs allow faster transition from starting gear to high gear. Half as many shifts to get from 24-10 versus a normal 10-speed 26-11
- Larger gear range, 10-tooth cog opens up high end and allows smaller rings for ground clearance
- Lightest cassette. Ever.
- More rear wheel clearance around spokes
- 2-tooth steps are safer in shifting than 1-tooth steps under big loads
- Currently fits any XD™ compatible wheel and driver body
NEW X01 DH X-HORIZON™ Rear Derailleur
The 7-speed X-HORIZON™ rear derailleur makes shifting smooth and reliable no matter where you ride. Engineered to maintain consistent chain gap across all seven gears, X-HORIZON™ eliminates vertical movement for faster shifting, reduced shift force and an end to ghost shifting. ROLLER BEARING CLUTCH™ technology and the 12-tooth X-SYNC™ pulley wheels hold the chain in place, reducing bounce and chain slap. And CAGE LOCK™ technology makes wheel removal and installation easier than ever. Paired with the X01 DH 7-speed shifter, X-HORIZON™ forms the backbone of X-ACTUATION™ technology—and that means completely smooth shifting action.
