SRAM DUB BSA Bottom Bracket Cups | 68/73mm

Elevate your MTB cycling experience with the SRAM DUB BSA Bottom Bracket, the cornerstone of modern drivetrain performance and reliability. Engineered to be the single, unifying component that simplifies your setup, the DUB (Durable Unified Bottom Bracket) system is a masterclass in engineering. It is designed to connect your crankset to the frame with unparalleled stiffness and longevity, ensuring every watt of power you produce is transferred directly to the trail. This bottom bracket isn´t just a part; it´s a fundamental upgrade for any serious mountain biker looking to optimize their ride.

The core benefit of the SRAM DUB system lies in its perfectly balanced approach. By creating a single oversized spindle diameter of 28.99mm, SRAM has found the sweet spot between the lightweight properties of smaller spindles and the stiffness of larger 30mm systems. This results in a bottom bracket that is not only incredibly robust but also impressively lightweight, helping you shed precious grams without sacrificing an ounce of durability. For the dedicated MTB cycling enthusiast, this means a more responsive, efficient, and reliable ride, whether you´re climbing steep technical ascents or descending at high speed.

Durability is paramount in the world of mountain biking, and the SRAM DUB BSA Bottom Bracket is built to withstand the harshest conditions. It features exceptionally well-sealed industrial-grade cartridge bearings, providing a formidable defense against water, mud, dust, and grit. This superior sealing technology significantly extends the life of the bearings, reducing maintenance intervals and giving you the confidence to ride hard in any weather. The smooth, low-friction performance of the bearings ensures your cranks spin freely, ride after ride.

Installation and compatibility are made simple. This BSA version is designed for the most common threaded bottom bracket standard, making it a straightforward upgrade for a vast range of mountain bike frames. It seamlessly integrates with all SRAM and Truvativ DUB cranksets, eliminating the guesswork and compatibility headaches that often plague bike builds and upgrades.

Main Features:

* Features SRAM´s revolutionary DUB technology for a lighter, stiffer, and more durable system.
* Engineered for superior protection against the elements, ensuring long-lasting performance.
* Provides a rock-solid connection between the crankset and frame for optimal power transfer.
* Designed for seamless integration with the complete ecosystem of SRAM and Truvativ DUB cranksets.
* Utilizes high-quality sealed cartridge bearings for smooth, reliable, and low-friction rotation.

Specifications:

* Model: SRAM DUB BSA Bottom Bracket
* Discipline: MTB Cycling
* Crankset Compatibility: Enables the installation of all SRAM and Truvativ DUB cranksets.
* Bearing Type: Sealed Cartridge Bearings (Industry Standard)
* Frame Interface: BSA English Thread (1.37" x 24 TPI)
* Shell Width: 68mm / 73mm (Spacers included for a perfect fit)

RLA

So far so good. Seals seem to be great not to let dirt and water in, so should last for a long time. Spins well.

No problem

Sotaro

This bottom bracket fits my titanium frame perfectly. I thought about buying a bottom bracket socket and tightening it with a torque wrench, but the BSA30 tool worked just fine.

RAFAEL

It is a basic product and it fulfills its function but its durability is poor. The price is very good and that is what makes it worth it but as I say it does not usually last more than a year in good condition if you want it to be fine. I recommend it if you are not demanding and are looking for something economical

I'm glad Sram are trying to standardise a bottom bracket so we don't have to keep buying different products. Let's see how long this lasts. This BB is light, feels well made and bearings run smooth. I would recommend

No, despite being compatible with your frame´s threads, the bottom bracket will not be compatible with the Race Face which is 24mm. This only works with Sram´s DUB system. Cpts

Hello, I have doubts if this cup is suitable for a 73mm BSA thread bottom bracket, for a Sram GX Eagle 10-52 12-speed Groupset with single chainring. I have seen some others with the measurement of 73mm and I have doubts. Thank you so much.

Answer of JESÚS

Hello. If you have 73 mm, this is the one you have to mount. It´s the one you see for 68-73mm bottom bracket shells. All the best.

Compatibility in trek and giant

2022/05/17

Brandon C

Is this product compatible with a Trek marlin 6 or a Giant heel 2? This answer Postscript would be very useful for me, both bicycles have threaded axles but I want to make sure if they are compatible

Answer of Adam

I cant answer re the specific bike but do know that you do need to measure the size of the frame the bottom bracket fits both width and diameter. I have a 2006 specialised epic, I took the measurements and then searched for a bottom bracket to that specific size. its been in for about 18 months with constant use and its great.
