Hi
I'm getting a new bike that's setup for BB30. There are so many BB standards out there and I don't 100% get all the new standards (although I do understand how the old tapered BB's work!)
Does anyone know if [url= http://www.chainreactioncycles.com/Models.aspx?ModelID=28019 ]my current SLX cranks[/url] will fit onto a BB30 BB? I have a shimano BB (think its hollowtech 2) on the current bike.
Cheers
No, they definitely won't. Although I have seen adapters for sale (Planet X, IIRC), I've no experience of them. BB30 axle is a different size.
If you want to sell the SLX I'm interested 😉
They will fit but you'll need some adaptors or a bb30 to hollow tech bottom bracket. I've got a push fit 30 bb with wheels manufacturing adaptor cups. Buy carefully though its a minefield out there!
Thanks for the help,
Would like to keep the SLX as they've been solid! CRC have a great deal on those at the mo BTW!
thefallguy - you say its a minefield - is there any one in particular you'd recommend? Or has anyone else had experience with these adaptors?
get a KCNC BB30 adapter, it will work fine then!!

Thanks....but the road/cross country use only puts me off, this bike will take a fair beating, so want something reasonably solid
Get the SRAM BB30 to BSA adaptor cups http://www.tweekscycles.com/Product.do?method=view&n=3477&p=339198&c=215&utm_source=Google&utm_medium=Base&utm_campaign=Bottom%20Brackets&gclid=CL3tsoLGjrcCFbMQtAod5WoA-A
Screw BB into cups (don't forget the spacers as needed), then press whole thing into frame with a headset press. Easy.

Gee, that adaptor will not work on BB30, the description is wrong on their website, it is a PF30 to BSA adaptor only BB30 is different but uses the same sized bearings,
Anyway I have some Wheels Manufacturing adaptors for sale http://singletrackmag.com/forum/topic/hope-xc6-hub-xt-chainset-tdf2012-dvd-charge-tyre-other-stuff
these fit into the bearings on a BB30 or PF30 and reduce the diameter to accept a Shimano 24mm crank spindle
the bearings in it are fine, and are easily replaceable, i used one for a year, and the bearings were still running smooth. used both for road and MTB.
Sorry thought there was a choice of buying a BB30 one or a PF30 one. Yes - that won't fit.
Problem is those BB30 bearings don't last long - pressing in an adaptor and running a normal HT2 BB seems the most durable solution.
This looks right though:

Thanks for the help, starting to understand this a bit better now, it does sound like a pain!
I already have a decent HT2 BB so getting an adaptor to press into the frame sounds like a good idea
