[#8374669]

So still trying to work out what to do on my carbon scalpel.

Something like [url= https://qwertycycles.co.uk/products/bb30-pf30-24mm-reducers ]These[/url] or [url= http://www.cannondalespares.com/Wheels-Manufacturing-BBright-and-BB30A-to-Shimano-24-mm-Crank-Shims/product_detail/3-42205 ]These[/url] what are the spacers for?
Ive ordered some Rotor BB30 bearings too.
TIA

What exactly are you trying to do? If its a bb30 frame you need bearings and circlips to retain the bearing the either a 30mm axle chainset and the correct spacers or the 24mm adaptors and then a 24mm chain set

If it's a pf46 frame you need the correct bb (bearings in a cup) then the same as above with the chainset

I think he wants to convert it to use threaded cups?

As in the photo and links guys!
I can only use the bearings that sit in the cups that are bounded into the frame, I can't fit the push fit bb's for that reason and have a spare xt crank that I'd like to use instead of having to buy a bb30 crank.
So was wondering if the converters in the links were much the same and why so many spacers?
Cheers

Any more help guys please...!
The bb30 bearings and circlips arrived today so need to decide on getting one of the converters or putting a wtd add for some bb30 cranks.
Cheers

He's asking about the shims folks.

I didn't need any, running a Shimano chainset in a Cannondale BB30 frame.

Cheers, guess they're for sorting out the chainline if needed?

Not sure if relevant but I used a FSA BB30 Threaded Adapter a few years ago and still going strong.

Pretty sure on my frame the bb30 bearing cups are bonded into the bottom bracket shell, if so I can't use a push in converter.

Used an FSA converter too. Like mentioned plenty of grease or copperslip or it will creak like a bas$%^&. Mine did
