Product Details

Overview & Technology

SRAM's PG-1050 cassette uses PowerGlide II technology to deliver quick, reliable cross-gear shifts under load. Built with hardened steel cogs and precision-machined shifting ramps, this cassette is designed to give road riders the wider range of gears they need without switching to a triple crankset. PowerGlide II uses optimized tooth profiles and ramp geometry to guide the chain cleanly from cog to cog, reducing hesitation and chain drag during aggressive climbs or surges. The PG-1050's 11-36T spread provides the low gears needed for steep climbs while keeping close steps for cadence control on the flats.

Key Features & Construction

The PG-1050 is built from high-strength steel cogs for long life and consistent shifting. The 11-36T variant ships at approximately 299 g (11-32) and is carefully profiled with PowerGlide II ramps and pins to speed up shifts and reduce wear. Construction highlights: • Cog material: hardened steel for durability and wear resistance. • PowerGlide II ramped teeth for faster, more predictable shifts. • Precise tooth progression: 11-13-15-17-19-22-25-28-32-36 for a road-friendly cadence range.

Fit, Compatibility & Installation

The PG-1050 is a 10-speed cassette designed to fit standard Shimano/SRAM HG freehub bodies, making it a direct swap on most road hubs. It pairs with 10-speed chains and shifters—use a 10-speed chain for optimum indexing and wear characteristics. When used with a compact 34/50 crank, the 11-32 and 12-36 options provide a wider overall gearing range than many triple crank setups while retaining simpler front shifting. Installation follows standard cassette installation procedures: grease the freehub lightly, slide the cassette onto the splines, torque the lockring to spec, and check derailleur limit screws and B-tension for smooth operation.

Who It's For

The SRAM PG-1050 is aimed at road cyclists who want a wider gear range without changing cranksets—gravel riders and mixed-terrain commuters will also appreciate the low 36-tooth cog for steep climbs. It's a great option for riders upgrading an older 10-speed drivetrain who need reliable shifting and long-lasting cogs at a value-oriented price point. If you ride hilly routes, carry loads, or want the cadence control of closer steps on the flats while still having low gears for ascents, the PG-1050 is an efficient, durable choice.

Frequently Asked Questions

Is the PG-1050 compatible with Shimano freehub bodies?

Yes. The PG-1050 uses the standard Shimano/SRAM HG spline and fits most Shimano/SRAM 8/9/10-speed freehub bodies. No special adapters are required for common road hubs.

Can I use a 10-speed chain with this cassette?

Use a dedicated 10-speed chain for correct spacing and wear characteristics. 10-speed chains match the cassette's tooth width and ramp spacing for reliable, indexed shifting.

Will this cassette work with my compact 34/50 crankset?

Yes. When paired with a 34/50 compact crank the 11-32 and 11-36 options on the PG-1050 provide a gear range similar to many triple setups, giving lower gears for climbs without changing your crank.

Can I mix PG-1050 with 11-speed SRAM or Shimano components?

While the cassette will physically fit common 11-speed freehubs with adapters in some cases, indexed shifting requires matched-speed shifters and chains. For consistent shifting performance, use components matched to 10-speed systems.

How durable are the cogs and what maintenance do they need?

Cogs are made from hardened steel for longevity. Regular drivetrain maintenance—cleaning, degreasing, and replacing the chain before excessive wear—will extend cassette life. Replace the cassette when you notice poor shifting or chain skipping under load.

What tools do I need to install this cassette?

Install with a standard cassette lockring tool and a torque wrench or adjustable spanner. A chain whip is recommended for safe removal. Follow torque specs on the lockring and check derailleur alignment after installation.

Buying Guide

When choosing a cassette, match the number of speeds to your shifters (this is a 10-speed cassette) and confirm freehub body compatibility. Consider your terrain: choose a wider range (like 11–36T) if you ride steep hills or carry loads; choose tighter steps (like 11–28T) for sprinting and fast group rides. Materials and weight matter: steel cogs provide durability and lower cost, while lighter alloy or titanium options reduce weight at higher price. For the best performance from the PG-1050, install a new 10-speed chain and follow proper torque and derailleur setup procedures.
