SRAM S200 Eagle B1 12-Speed 1x 32T DUB Boost Crankset

The SRAM S200 Eagle DUB crankset is a no-frills aluminum mountain crank with a 32T steel X-Sync 2 chainring, built to keep a 12-speed Eagle drivetrain running ride after ride. This version uses the standard DUB spindle and a 52mm chainline for 141/148 Boost hubs.

It is offered in 155, 160, 165, 170 and 175mm arms. The DUB bottom bracket is not included, so pair it with the DUB bottom bracket your frame takes.

Who It's For

• Mountain riders on 12-speed SRAM Eagle drivetrains
• Boost (141/148) bikes with a 52mm chainline
• Riders replacing a worn crank who value durability and simplicity
• Consider a different crank if your bike uses Super Boost spacing, a 55mm chainline or a Powerspline bottom bracket

What to Look For

• Spindle interface: SRAM DUB (standard width); bottom bracket sold separately.
• Chainline and spacing: 52mm, for 141/148 Boost hubs.
• Crank length: 155 to 175mm, all with a 32T ring.

Key Features

Aluminum arms. Simple aluminum arms keep this crank durable and serviceable for everyday trail riding.

DUB spindle. The 6061 aluminum DUB spindle uses SRAM's DUB platform, which SRAM says brings a uniform approach to fitment, better sealing, and forward and backward bottom bracket compatibility. The bottom bracket is sold separately.

Steel X-Sync 2 ring. The 32T ring mounts with SRAM's 3-bolt direct mount interface. SRAM states the steel ring delivers the same chain retention as all other Eagle cranksets.

Boost chainline. A 52mm chainline lines up with 141/148 Boost hub spacing.

Rider Intent Summary

• Biggest strengths: Eagle 12-speed compatibility with a hard-wearing steel ring on DUB.
• Tradeoffs: Bottom bracket sold separately; steel ring weighs more than aluminum.
• What makes it different: A straightforward DUB crank for standard Boost bikes, in five lengths.

Victory's Take

At Victory Bicycle Studio this is our go-to replacement crank for Boost trail bikes that just need to keep working. We confirm 52mm versus 55mm chainline before ordering so you do not get the Wide version by mistake.
