Enduro MRA 2437 LLB: An ABEC-5 Angular-Contact Bottom Bracket Bearing Built to Handle Everything Thrown at It, Ride After Muddy Ride.

Your bottom bracket bearing is the unsung workhorse of every pedal stroke, and Enduro knows it. The MRA 2437 LLB is an ABEC-5 Angular-Contact bearing measuring 24mm x 37mm x 7mm with C3 clearance, purpose-built to handle the punishing lateral loads that chew through lesser bearings. Deep-groove design races packed with Grade 10 balls and loaded with 90% fill Mobilux NGLI 2 high-pressure waterproof synthetic grease mean this thing is ready for whatever the trail dishes out.

The Angular-Contact design is the real magic here. When installed correctly with the black seal facing in, every single ball in the bearing engages with the race, spreading force over a larger surface area to decrease friction, minimize wear, and squeeze more life out of each bearing. That is not something your stock bearing is doing. The dual-lip labyrinth LLB seals sit in a micro-groove to form a full labyrinth seal, locking grease in and keeping mud, water, and grit out.

This is the go-to direct replacement bearing for Shimano bottom brackets running a 24mm OD spindle. Weighing in at 30.99g and rated to a static load of 773lbf / 3.44kN, it is a small part that makes a big difference. The Enduro line is also available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD15 with ceramic or stainless balls for riders who want to step up further.

Why You'll Like It

Smash a rock garden on your Shimano-cranked rig and your bottom bracket is taking a beating with every pedal stroke, but swap in the MRA 2437 LLB and you will notice how long that silky smoothness actually lasts. The angular-contact design and Grade 10 balls mean your BB is not grinding itself to dust after a few wet rides, which is exactly what you need if you are the type to ride through anything. At 30.99g, it is a no-brainer upgrade that keeps your drivetrain honest all season long.
