Sram DUB PressFit 92 (89/92) Bottom Bracket

Hello, I would need bearings with a 29 mm crank axle diameter and a width of 6.90 mm, do you have such a thing

Hello,

unfortunately we don’t have standalone bearings for DUB crank axles available, only complete bottom bracket cups:

Have a nice day.

Hello, is this the correct axle for a Specialized Epic Expert WC 2016? Everything is original – including the Sram cranks. Specs: cranks Custom Sram S-2200, carbon, PF30 spindle, 30T, 94mm BCD spider; bottom bracket Sram, PF30, OS press-in bearings, sealed cartridge.

Hello, 

thank you for your question.

Based on the specifications found, the following bottom bracket should fit your bike, since you do not have cranks with a DUB spindle:

Hello. I have this bottom bracket (https://www.koloshop.cz/press-fit/Shimano-Deore-BB-MT500-PA-stredove-slozeni-Press-Fit.html), can I use this bottom bracket so I can switch to sram dub cranks?

Hello, yes, that is the correct bottom bracket.

Hello, I bought the Sram DUB PressFit 92 (89/92) bottom bracket; the package contains two plastic spacers of different sizes. Could you please advise where they go?

Hello, the spacers are placed according to the width of the bike frame’s bottom bracket shell.

Hello, I have a bottom bracket SRAM DUB PF integrated/shell 41x92mm and cranks SRAM X01 DUB Eagle Boost Carbon crankarm, is it possible to replace the bearings with other ones? There is constantly an unpleasant creaking sound, which stops for a while after a service visit (probably cleaning), or do you have a tip to fix it?

Hello, press-fit bottom brackets are a bit of an unfortunate solution from bike manufacturers in this regard. Unfortunately, for the DUB spindle there are no other bottom brackets than Sram.

Can the bearings be replaced in this pressfit, or does the whole kit have to be replaced? Do you have those bearings in your range?

Hello,

with these types of bottom bracket cups, the complete set is always replaced.

What should I use when pressing it in to prevent unwanted noises?

Hello,

grease is used on the cups during installation. You can use the same grease as for bearings.

On my MTB Trek Procaliber 9.7 I have a GXP bottom bracket axle, the shell is 91 mm long,, the bearing width is 41-42 mm. Will this axle fit there? I’m thinking about switching to carbon cranks with a DUB axle.

Hello,

yes, this bottom bracket is the right one. However, you can’t fit your current cranks into it—only new ones in the future with a DUB axle.

Hello, I currently have an Aerozine PF2405 in the frame, will the axle be compatible?

Hello, 
 unfortunately it won’t; DUB PF92 has a larger bore than PF2405, into which Shimano cranks with a 24 mm diameter can be installed.

I’m switching to SRAM EAGLE DUB and I need a replacement for my current bottom bracket “SHIMANO BB-71-41A” (bike Superior XP 929 2017) — is this part correct, or which SRAM bottom bracket should I buy?

Hello,

if the bike has the original Press Fit 41 mm bottom bracket and you want to use cranks with a DUB spindle, you will need these cups:

Hello, I’d like to ask what material the cups on the Sram DUB PressFit 92 bottom bracket are made of? Plastic, steel, or aluminum?

Hello,

the cups should be aluminum, and in the middle there is a plastic tunnel.
