SRAM DUB Bottom Brackets

Ready to make the switch to SRAM DUB? Kogel's ceramic bottom brackets have you covered with smooth rolling long-lasting ceramic bottom brackets for your mountain bike.

Kogel's SRAM DUB collection is built around the same bearings used in our bottom brackets for 30mm spindles and covered by the same Very Few Questions Asked, 2 year replacement warranty as all our products.

SRAM DUB Explained

SRAM DUB is a crank spindle standard for mountain bikes, introduced in 2018. In 2019 the road standards were added.

The crank spindle is designed around an axle diameter of 28.99mm and introduced to replace the two spindle types that SRAM offered in the past: GXP (24mm diameter with a stepdown to 22mm at the non-drive side) and BB30 (30mm diameter).

A Standard of One

SRAM claims that by reducing the diameter by 1mm, they had more room available to build sturdier seals, which makes for longer lasting bearings.

A fun detail is that the bottom bracket and crank system is actually built around a 30mm inner diameter bearing, with an outside diameter of 40mm. Not larger, but smaller than a stock BB30 setup.

WHY Upgrade/Replace Your Bottom Bracket

Even new bikes with new high-end drivetrains can, and usually do, ship with bottom brackets using steel bearings.

Even if perfectly maintained, those steel bearings just won't roll as smoothly or efficiently as our ceramic steel bearings.

Kogel Ceramic Bearings are:

  • More symmetrical (i.e. round) and built to stricter tolerances than steel bearings
  • More efficient for power transfer than standard bearings
  • And, won't deform, flat-spot, crack or get pitted

Beyond the basics of keeping your bottom bracket clean and maintained, perhaps the most important step is ensure your bike's best performance is using a bottom bracket manufactured with high-quality ceramic bearings.

RIDING ON BORROWED TIME

No amount of bearing grease can fix a cheap bottom bracket. It will never ride as efficiently as a ceramic-based bottom bracket. Over time the performance only gets worse becoming, literally, a drag on each pedal stroke.

DRIVETRAIN BLISS

Now imagine riding your bike with ceramic bearing components, feeling the silky smooth 100% power transfer from each pedal stroke to your rear wheel. Your crankset spins almost completely silent with hardly any effort. A feeling lasting for years, not months.
