Sram Crankset Spindles Explained | GXP BB30 PF30 DUB

[@kidsafe]

The real reason why SRAM moved to a 29mm spindle is the same reason why Shimano is on a 24mm spindle instead of a 25mm spindle. Standard 680x bearing IDs come in 5mm increments. Using 29mm and 24mm spindles means you can place a Delrin tophat in between…that prevents galling between the metal spindles and hardened steel bearing races.

Good tutorial and excellent information really appreciate the content

[@cooltuque]

Since the ends of the spindles are the same between dub and pf30, am I right in understanding that you could change a pf30 spindle to a dub one and it would fit both crank arms? In the video you show that the spindle ends are the same and use a dub non drive side crank arm with a pf30 drive side crank. I have an old pf30 crank set and hoped to put it on my DH bike. For that I need the right spindle length (researching that now) and the dub width.

[@BlackWaterCyclist]

The issue with DUB is that the Nondriveside Arm is bonded permanently to the DUB spindle. If you can find a dub spindle somewhere that allows you to screw the Non drive side cranks on then yes you can swap to the DUB spindle. The only company I know that offered it was stages but their splines are clocked differently so you have to use their crank arm with the spindle and now they are out of business. I have purchased non drive side dub arms and spindles before for cheap and put a PF30 driveside crank arm on it for some cheaper builds.

GXP spindle is 22mm on the non drive side so it will not work with the Shimano BB. The drive side is 24mm and will work with the drive side Shimano BB but the non drive side, you need a GXP BB or an adapter sleeve that goes on the GXP 22mm spindle to make it 24mm.

Hi BC, thanks for this awesome tutoriell! A additional question about running a modern Quarq Dzero Dub Powermeter with a Sram red 11speed etap BB30/386 crank (8bolt): I heard Sram says officially that "its not compatible. it would fit but the chainring(s) would be ca.1.5mm offset". My questions: 1. is this correct? 2. If it's correct, what is the reason for this? (is the dub spindle 3mm shorter or longer? - I have no other explanation)? 3. What is yout thought on this combination? Thank you very much!!

[@BlackWaterCyclist]

I am sorry for the delay, just getting back into KZbin after taking a break. The DUB spindle is every so slightly wider than the older 30mm Sram spindles. I had a wider than normal T47 86.5mm BB (85.5mm is normal) on my titanium bike and I could run the dub cranks but not the 30mm cranks because they were too narrow. So putting the older Quarq on there will work. Just need to adjust your front derailleur properly. 1.5mm is nothing when it comes to front derailleur adjustment. If you are running 1x then it will not be an issue. Did you try it?

[@BlackWaterCyclist]

That is correct. You may have to add a few spacers if you have the newer Transmission crank which is the same width as the CL55 dub mtb cranks. Transmission/CL55 cranks have a 6mm wider spindle so you would need 3mm spacer on each side.

[@user-0xDEEDBEEF]

I currently use a sram gxp crank and Shimano bb52 and there's a wobble I think there's no spacers in there

[@iwamotomasanori754]

So,,, SRAM BB30 has longer spindle than the original cannondale BB30? then can we fit SRAM BB30 road crank to BSA or BB386 frame if we have proper BB? One anoter question is, In case of 8 bolt patterns, can spider interchangable between GXP and SRAM DUB or BB30 crank?

[@BlackWaterCyclist]

Sorry for the delay on this. I am just getting back to KZbin. Yes as long as you have the proper BB then it should work. The 8 bolt pattern is the same between all of them but the Dub spindle is about 1.5mm longer so if you put a Quarq or Spider that is 8 bolt off the older 30mm spindles onto the Dub, it will have your chainring sit outboard 1.5mm. Not the end of the world, especially if you are running 1x.

Hello, Do know if SRAM BB30 (30mm) spindle like Stages D Spindle would work with Cannondale SL or Cannondale One cranks? In short are SRAM and Cannondale BB30 spindles interchangable if they are correct length?

[@BlackWaterCyclist]

I am sorry, I am just getting back into KZbin. You are right that the spindle interface is the same between Cdale and Stages but the problem with stages is that they have clocked the interface differently so you have to use their non driveside crank arm. If you put a regular crank arm on it, you will have one arm at 12 o clock and the other at like 2 o clock.

[@lucianocaldas69]

Hi thanks for the video!! Do you know if the 8-bolt pattern used with powermeter is the same between GXP cranks and Dub cranks? I mean, a modern powermeter spider named for Dub cranks, with the 8-bolt pattern would fit in a GXP crank? Thanks!! Best,

[@BlackWaterCyclist]

Yes it will fit fine. The crankset width is almost identical between the DUB and GXP so chainline should still be good.

There are so many variables here. Did you get it to work? With a shimano 24mm spindle it is easy to use an adapter but with GXP, you have to have the non drive side at just the right location bc it uses a 22mm Internal bearing and has to be placed in just the right location.

[@adamhindle9215]

GXP was bad, for engineering reasons (floating driveside bearing, no way to preload the bearings). BB30 was even worse and has rightfully died a long time ago. PF30 wasn't quite as bad but had tiny bearings so ate those for fun. DUB tried to solve that problem by shaving 1mm off the diameter, so basically the same and almost as bad. In summary bad, badder, not as bad, not as bad. Ultimately, avoid. Sram is doing some excellent things, in mtb and road, but cranks aren't one of them. Also when you say 'bottom bracket', in reference to the frame, then you should say 'bottom bracket shell'.

What about "DUB Boost", "DUB Wide" and "DUB SuperBoost +" spindle lenghts to address 52, 55 and 56.5mm chainlines. The spindles are etched with "DUB or DUB SL", "DUB Wide" and "DUB SB+" to I dentify them. I believe the "SL" stands for Standard Length" not "Super Light".

Hi Mike, the issue you may have is that yours is 3 bolt and all the newer Quarq D Zero power meters are 8 bolt. If you could find an older lightly used Quarq Elsa or Riken (both 3 bolt) then you would be good to go. Quarq claims you can't swap between arm lengths with the older Elsa/Riken or it will read higher or lower depending on which way you move on the arm length but honestly it will not be much of a difference. A few second hand companies make 3 bolt power meters like Xcadey or Power2Max that you could swap it with. Another option is to find a right side 8 bolt and a D Zero power meter but that will be hard to come by in your exact length. I hope that helps.

You can shim 24mm spindles on the axle. GXP is obviously a different animal. Sometimes the shim for the BB is too thick and they do not offer thinner ones and you need to shim on the axle.

[@CWBmtb]

Aluminum spindle is sooner or later going to wear and be trash. Switching to shimano because of this

[@BlackWaterCyclist]

I have had SRAM alloy spindles for years with no issues. The original PF30 spindles that were aluminum would have issues since they connect directly to the steel races of the bearings and would wear and cause clicking or creaking. The newer Dub are better because they use a plastic sleeve similar to shimano bearings so they do not have the wear like previous PF30 cranks. Shimano has had more crankarm issues than SRAM over the years. I would say SRAM have been more reliable than Shimano in the crankset arena though that is not the case in most parts with SRAM vs Shimano.

[@CWBmtb]

@@BlackWaterCyclist most of the spindles in the video already show some small amounts of wear. For people that ride a lot, it happens way too soon regardless of the amount of maintenance. Thats my experience and the same for many people I know that ride XC.

[@BlackWaterCyclist]

Sorry they did not have DUB wide when I made this video or at least it was very new. Dub Wide for road is a total of 5mm wider spindle. Everything else is the same. SO you have a 5mm wider Q factor and it moves the Front Derailleur wider by 2.5mm to give more room for larger tires. Wide for MTB does the same, just makes the spindle wider for more tire/chainstay/chainring clearance.

No one knows what the heck i am talking about because Sram didnt even have enough courtesy for people to put a different model number on the shorter-or-longer spindle, they both say PF-30. So it would seem no one on planet earth has a long spindle, Sram red 165mm 53/39 crankset, PF-30 OR GXP, new or used, for sale, so that i can match the rest of the components on my bike. Oh, and if my A1 derailleur goes bad, they want $800. It would seem Shimano arent the only greedy, inconsiderate ones, after all.(Hammerhead)

I do not like GXP. I do not like Sram's HRD (Hydraulic Road Brakes) I do very mike like their eTap/AXS two button shifters.

DUB is superfluous and unnecessary as the 30mm already exists, already has bottom brackets that exist and works just fine. I have two bikes with threaded English 30mm bottom brackets and there is nothing wrong with them. SRAM basically created a new size with all the complications that it creates for no apparent reason. The 'bigger bearing' claim isn't real. Just SRAM being SRAM, IMO.

Most 30mm bb’s have the cranks straight onto the races of the bb bearing, sram dubs are a 30mm Id bearings but with a plastic sleeve isolating the crank from the bearing. This will prevent galling on the axle. 30mm has its issues depending on the frames bb standard, especially bb86 which is why most have to use double row bearings to try and extend their life.

Worst crankset ever!
