Thomo Posted January 20, 2016 Posted January 20, 2016 Hi,Seems it's almost impossible to find a difinitive answer.What I have established is that true BB30 cranks won't fit 386EVO (86mm BB) because the spindles are too short.So what is the mimimum spindle length required.?Some BB30 spindles are apparently longer (Force 22), and 24mm cranks all seem to fit too with the appropriate adaptors.So just how long are these spindles.? Will a 109mm SiSL2 spindle/crank fit 386EVO.? Thx.
Spoke101 Posted January 20, 2016 Posted January 20, 2016 Just gone through this process. There is quite a lot of decent info out there on the net. I will see if I can dig it up again.Sram do make 2 different BB30 Cranks one with a 95mm and one with a 104.6mm spindle. So 104.6 is minimum length required, so your Cannondale Cranks should work. From what I have found out (done 2 bikes like this now) is that even if the cranks fit chain line can be a problem. This was with a Quarq powermeter and a Campag EPS Groupset where the crank had to be spaced so far out so that the spider didn't rub the frame that the Front Derailleur would not shift the chain into the big ring. FSA and Power 2 max make a number of compatible BB30 Cranks.
Thomo Posted January 20, 2016 Author Posted January 20, 2016 Thanks - appreciate the response.Agree - there is a lot of info on the net, but quite a lot of it conflicting too.Let's just say I've seen more nays than yays for SiSL2 on 386EVO which surprised me.
JA-Q001 Posted January 20, 2016 Posted January 20, 2016 Unfortunately I do not think your SiSL2 crank will work on the BB386. Frame manufacturers make use of the86mm BB in order to use larger tubes, thus taking up all the space. The SiSL2 cranks use a 3mm(?) spacer on the driveside when used with a true BB30, this spacer falls away with a PF30a. So meaning that the chainline would need to be pushed out and the crank can come into contact with the frame if you want to use a BB386 frame. I have checked and the closest larger BB that may be able to take a SiSL2 crank is the BBright, this BB width is 79mm, but is only extended on the NonDS, on the DS it has normal BB30 spacing.
Thomo Posted January 20, 2016 Author Posted January 20, 2016 Thanks for the feedback.But that's exactly what I meant with conflicting opinions.
Thomo Posted January 26, 2016 Author Posted January 26, 2016 Any thoughts on using a MTB spindle which I believe come in different lengths.?
madbradd Posted February 10, 2016 Posted February 10, 2016 Also a bit interested in this as I have a bb86 frame and all the new cranks other than shimano seem to be 30mm. My question is can you get different length spindles for different cranks? I see that there are different length ones for stages power meters.... but not sure why or whether you can use them on all cranks.

BB86 is 24mm specific as I understand it.I speak under correction, but think the Stages spindles you refer to are also 30mm.BB386EVO is 30mm but longer than standard BB30 cranks.

intern Posted February 11, 2016 Posted February 11, 2016 I recently got a Specialized with an OSBB; did some research as the 167.5mm cranks are shorter than anything I've used previously. Ultimately, I've kept the short S-Works cranks, but I did find this article very useful and suspect you will too: http://www.bikeradar.com/gear/article/complete-guide-to-bottom-brackets-36660/

Of course only applicable if I decide to get a Crank based PM rather than a Powertap Hub
