Sram PG-1210-B1 Eagle 12sp. cassette 11-50t.

Description

When the trail tilts upward and you don’t want to lose momentum, the right cassette makes a bigger difference than it might seem at first glance. The Sram PG-1210-B1 Eagle 12sp. cassette 11-50t gives you a wide gear range for long climbs as well as brisk transitions, while still delivering a reliable, “no-fuss” feel. It’s the kind of component you mostly notice when it keeps working just as well, ride after ride.

Main benefits

The SRAM PG-1210 Eagle cassette is built for MTB riding where steep climbs, flats, and technical sections alternate and you want to change pace smoothly without overthinking your gearing. With a range from an 11-tooth smallest sprocket to a 50-tooth largest sprocket, it’s easy to find a light gear for climbing and a usable gear for faster sections. A practical advantage is the replaceable “speed” sprockets for e-MTB—specifically the 11-tooth, 13-tooth, and 15-tooth sprockets—so when they wear out, you don’t have to replace the entire cassette. Compatibility with a splined freehub body makes it easy to use across a wide range of bikes and hubs from different manufacturers.

Technical specifications

The cassette’s technical designation is PG-1210-B1 Eagle, and it’s designed for a 12-speed drivetrain, typically in a 1× setup where a single front chainring is paired with a wide range at the rear. The gearing is arranged from an 11-tooth sprocket up to a 50-tooth sprocket, covering both climbing and faster riding on flatter terrain. For proper function, an Eagle chain is recommended, as it’s designed for precise 12-speed shifting. The cassette is intended for a Shimano HG11 freehub, which is a common solution on many MTB bikes and makes replacement easier without needing to change the hub.

Conclusion

SRAM PG-1210 Eagle is a durable MTB cassette for riders who want a wide gear range and long service life in real-world terrain. If you’re building or servicing a 12-speed drivetrain with a compatible Shimano HG11 freehub and using an Eagle chain, this cassette makes sense both technically and practically.
