The SRAM PG-1170 11-speed cassette represents the pinnacle of road and gravel drivetrain performance for Force 22 and Red 22 groupsets. With its 11-36T variant, it opens new horizons for the demanding rider: extended range for steep climbs, smooth transitions across all terrain, and semi-spider construction that combines light weight, rigidity and absolute silence. Part of the PowerGlide family, this cassette embodies the WiFLi philosophy (Wider - Faster - Lighter) and stands as a benchmark for road, cyclocross, gravel and 1×11 single-chainring setups.

PowerGlide technical architecture and semi-spider construction

• Optimized semi-spider design: The 3 largest cogs (28-32-36T) are mounted on a forged aluminum spider, reducing weight while guaranteeing rigidity, perfect concentricity and silent transmission.
• PowerGlide II technology: Redesigned tooth profiles across all 11 cogs, with optimized shift ramps that eliminate parasitic flex and ensure ultra-fast, precise and virtually silent gear changes.
• Heat-treated high-strength steel: Cogs machined from hardened steel that maximizes lifespan under high stress (competition, long rides, intensive gravel use).
• Anodized aluminum alloy lockring: Laser-etched finish, featherweight and corrosion resistant, for reliable tightening and easy maintenance.

WiFLi performance and extended range

• WiFLi technology (Wider - Faster - Lighter): The 11-36T range offers a 13% wider gear ratio spread than an 11-32T, allowing you to tackle steep gradients in 1×11 (with 44T or 46T chainring) without compromising speed on the flat.
• 11 speeds, 11 perfectly spaced gears: Sequence 11-12-13-15-17-19-22-25-28-32-36T, designed to maintain optimal cadence in all circumstances — technical climbs, false flats, accelerations, sprints.
• 1×11 and 2×11 drivetrain compatibility: Cassette designed for SRAM Force 1, CX1 and Force/Red 22 derailleurs with medium or long cage equipped with X-Horizon™ technology (straight parallelogram). Also compatible with certain Shimano derailleurs (Ultegra 6800 GS, 105 5800) with fine B-screw adjustment.

Compatibility and system integration

• HG 11-speed road freehub body: Mounts on Shimano/SRAM HG 11-speed bodies (wider than 9/10-speed). Not compatible with XD/XDR.
• Recommended chain: SRAM PC-1170 Hollow Pin, compatible with Force 22 and Red 22, to fully exploit PowerGlide profiles and guarantee ultra-silent shifts.
• Packaging note: The 11-tooth cog is placed behind the cassette in the original packaging — designed to prevent any deformation during transport.

Primary applications

• Gravel and cyclocross: The 36T allows you to attack technical singletrack, steep dirt ramps and broken sections with generous gearing, while keeping a road single-chainring (44T/46T) for rolling portions.
• Hilly road and competition: Provides a comfortable margin for climbers seeking an additional gear without switching to a triple chainring, while staying within the light weight and responsive philosophy of road drivetrains.
• Bikepacking and long distance: Proven reliability on rides of several thousand kilometers, with superior lifespan thanks to heat-treated cogs and spider design that distributes stress.
• Intensive indoor training (trainers, Zwift): Used by many cyclists on Neo, Kickr, etc. to benefit from smooth and silent gear changes during demanding intervals.

Available variants

The SRAM PG-1170 range comes in several gear ranges to suit all rider profiles and disciplines:

• 11-36T variant (this specification): EAN 710845764349 / Weight 366 g / Sequence 11-12-13-15-17-19-22-25-28-32-36 — Maximum range for extreme gravel, cyclocross, 1×11 road, requires SRAM Force 1/CX1 medium/long cage derailleur with X-Horizon™ technology or Shimano equivalent with B-screw adjustment.

Usage and maintenance advice

• Installation: Use an appropriate cassette lockring tool and respect the recommended torque. Check orientation (small cog facing outward).
• Chain lubrication: Keep the chain clean and well lubricated to preserve PowerGlide profiles and maximize cassette lifespan.
• Wear and replacement: Regularly inspect wear on the most stressed cogs (11T, 13T, 15T). Replace the cassette as soon as teeth become pointed or shifts become hesitant.
• Optimal combination: Pair this cassette with a new SRAM PC-1170 chain and a SRAM Force 1 or CX1 derailleur to exploit 100% of the system's capabilities.
