SRAM Dub English/BSA Threaded MTB Bottom Bracket

Sram is an amazingcompany making quality parts. It fit perfect with new sram nx groupset

Easy peasy lemon squeezy install. Well built and comes w/ multiple spacers for different brand bikes. Used this to replace the threaded BB on my 2023 Stumpjumper Evo Expert, perfect fit/function and super smooth quiet bearings.

Producto original. Llegó rápido.

Producto orinal ya instalado y funcionando a la perfección

Fits as described. No problems. Spacers for T type transmission are included with crankset, so I didn’t need the special T type bottom bracket kit. This fit perfectly.

Great product

Well it took me a minute to get all the correct components This BB DUB being the final element. I gotta say I like it, a lot. One tool is a positive well two Alan wrench but crank removal & install far easier. Most important though this crank system is exceptionally SMOOTH!

Works as advertised. All parts appear to have durability as well as quality. The plastic ring used to properly gap the crank arm from the bottom bracket with a three or 4 mm screw is made out of plastic. That might be OK, but there are other options out in anodized aluminum.

SRAM Dub original fonctionnel et compatible

Excelente qualidade, fácil montagem e funcionamento como esperado, muito bom. Vem acompanhado com todos os espaçadores necessários. Sram Rocks

シマノクランクからDUB規格のクランクに交換のため購入。 セラミックベアリングではないですが、BBにセラミックは個人的に思っているのでこれで満足

SRAM engineered by cyclist for cyclist is there anything else to say? Future references and Newton meter (Nm) specs are as following : SRAM AM BB DUB BSA 68/73 ROADMTB ,73 ROAD WIDE (Model 00.6418.015.000) The recommended torque specifications are: Bottom Bracket Cup Torque: Torque: 54 Nm (40 ft-lbs) Tool Required: 46mm, 12-notch bottom bracket tool (e.g., Park Tool BBT-79.3 Crank Arm Bolt Torque (SRAM DUB Crankset): Torque: 54 Nm (40 ft-lbs) Tool Required: 8mm Allen wrench Correct BB Shell Preparation Procedure (BSA / Threaded) Clean BB housing using isopropyl alcohol 99.99 pure and clean paper towel or shop towel to clean out threads from the BB or BSA housing before apply Park Tool ASC-1 grease to the BB's & threads before installation. Best practice: Use a lint-free shop towel if available Paper towel is acceptable but may leave fibres—inspect threads afterwards Run the towel through the threads, not just the shell faces Use a torque wrench to avoid over-tightening, which could damage the bottom bracket or frame. 👍 Pros Lightweight and sealed Broad DUB crank compatibility Easy threaded installation Affordable compared to many aftermarket options 👎 Cons Bearings not serviceable Durability varies with riding conditions Spacer setup complexity Some riders report life span issues in harsh terrain 📌 Verdict The SRAM DUB BSA 68/73 bottom bracket is a solid, budget-friendly choice for riders running SRAM DUB cranks on frames with a 68/73 mm BSA shell. It’s functional, lightweight, and broadly compatible, though it’s not the most robust option if you ride frequently in wet/muddy conditions or want a truly serviceable unit. For most casual and trail riders, it represents decent performance for price; for more demanding use, consider a premium threaded BB with replaceable bearings.

More than a yr of use and no any problems
