Hi Folks, I’m looking at getting a 165 mm crank for my big bike but I literally have no idea which one I need. I have a hope pressfit BB with a DUB adaptor. I have no idea what that means either. Is it this one? > **[Stages Power L - Stages Carbon BB30](https://saddleback.co.uk/products/stages-power-l-stages-carbon-bb30?variant=10822766690347¤cy=GBP&gad_source=1&gclid=CjwKCAiA0PuuBhBsEiwAS7fsNeLQ0KLD7d7m87PA8GjiCJwDuXzUui9jz50P2TNn6HjSDnaSTq9VORoC3AYQAvD_BwE)** > > Stages Power L - Stages Carbon BB30 DESCRIPTION The carbon Stages Power Meter L for 30mm is compatible with SRAM BB30 and RACE FACE NEXT SL (when fitted with the applicable Stages 30mm Spindle sold separately) The crank arm is compatible with 30mm... And if so, which of these adaptors do I need? BB Spindle Options not included: Stages Cycling spindles for 30mm are available in five options to purchase seperately: - : A) For SRAM Red 22 BB30 - : B) For SRAM Force 22, Rival 22, Force/Rival CX1 - : C) For 2015 model/year or newer SRAM BB30 mountain cranks with a 9mm driveside spacer - : D) For 2015 model/year or newer SRAM BB30 mountain cranks with a 15.5mm driveside spacer - : E) Race Face Next SL I am so confused. 😫 ---

If I am understanding you correctly - you have a PF30 bottom bracket for a DUB spindle. The DUB spindle is 29mm and the link you listed is for a stages crankarm for a BB30/PF30 standard 30mm spindle. Are you replacing your entire crankset or is your current X01 a 165mm and you are just trying to add power? ---

I wrote a long reply and then deleted it because I realized I completely misunderstood the situation. The bit that was worth keeping is: > I’ve never bought from these people since I’m in the UK, but if you’re US based then I think PowerMeterCity is well regarded for their product selection and especially for the kind of specific advice they will provide: [Power Meter Compatibility FAQ - Power Meter City](https://powermetercity.com/faq-category/product-information/) And even more specifically, this page: [I have a SRAM MTB crankset. What power meter can I use? - Power Meter City](https://powermetercity.com/faq/i-have-a-sram-mtb-crankset-what-power-meter-can-i-use/). It seems to say Stages BB30 crank arms can work with DUB cranksets **if** you also replace the spindle with Stages Spindle version G. As far as I can tell that also means you are changing from a 29mm DUB spindle to a 30mm one, which requires a 30mm bottom bracket. But since you say your BB has a DUB adaptor, it seems likely that if you remove the adaptor it is actually made for 30mm which would work with Stages Spindle G just fine. You’ll need to confirm that by going on the Hope website and figuring out exactly which BB you have though (and maybe even emailing them to confirm whether you need to change the configuration of spacers etc. when you remove the DUB adaptor.) ---

> [@JoPage](#): > > I have a hope pressfit BB with a DUB adaptor. I have no idea what that means either. Sram marketeers, in all their wisdom, decided a couple years ago to create another standard „DUB“ that has a 28.99(lol) mm spindle diameter oposed to the 30mm. If you‘re trying to replace your current crank with a shorter 165 crank you need to make sure that it’s got a 30mm spindle diameter or, since you already have the DUB adapter, you can get SRAM DUB cranks with a 29mm spindle diameter. If you‘re riding clipless pedals I‘d consider the new Assioma SPD. ---

I’m going to restore even more of my deleted post now that I’ve seen the price of Stages BB30 + Spindle G: it’s $635 on that website. Might be available cheaper elsewhere, but if that’s really what it’s going to cost you then it might be worthwhile looking into replacing the crankset entirely and getting a spider based power meter which will be more robust and give you total power (rather than just doubling your left side power): > [@alexfthenakis](#): > > This is what I bought and I think is the most direct ‘official’ option for you, but it seems like it might have been discontinued now that the new T-Type power meters are out: [PM-XX-1-B2 | SRAM](https://www.sram.com/en/sram/models/pm-xx-1-b2). It also looks like it only comes in 170mm so you’d end up having to buy the cranks, spider, and chainring separately in order to get 165mm (the cranks themselves do come in 165). > > I also looked at getting the entry level power option for the Transmission groupsets: [X0 Eagle AXS Transmission Power Meter Crankset | FC-X0-P-D1 | SRAM](https://www.sram.com/en/sram/models/fc-x0-p-d1). That will fit the same BB no problem, but I read that SRAM moved the chainline a bit further outboard (so the chainring is a few mm further to the right as you look down whilst riding). I’m pretty sure I saw people in forums saying they had fitted the new chainsets with the old rear derailleurs and shifting was absolutely fine, but officially I think SRAM says they aren’t cross-compatible. I wasn’t willing to take the risk so I got hold of the old version I linked above. > > You could also look at third party crank and spider options from the likes of Power2Max, Magene, and XCadey which are all well regarded but maybe don’t have the same kind of customer service support you’d get from SRAM. I don’t know enough about any of those options to suggest anything specific though. ---

Thanks folks, I’m UK based so will be buying over here. I was hoping it would be simple like it was for the XT crank on my other bike - literally whip the left arm off and put the new one on. Seemingly not, but thanks so much for all the help. The cranks on there are 165 mm at the moment. The G Adaptor is out of stock at the moment but they should have stock in about 3 weeks, apparently. I run flat pedals so power pedals are not an option. I can’t really afford to replace the entire crankset, although if I was going to go that route I would get the SRAM option there. ---
