What accessories go with this?

Hi,

Does the price for this item include for the supply of the bottom bracket or will that need to be purchased separately?

Thanks.

Answers

Answer: 
The Dura-Ace crankset uses the Hollowtech axle which is 24mm in diameter. This makes it fully compatible with the PF-BB91 road bottom bracket as it uses the 24mm standard too.

The two items will work perfectly well together in an easy to install and set-up system.

Answer: 
To fit this chainset into a Press Fit 30 frame an adaptor will be required.

The adaptor will allow a Shimano threaded bottom bracket to be installed which will be compatible with this chainset.

Compatible with Cannondale BB30?

I currently have Cannondale SI compact carbon crankset (made by FSA) on my Cannondale synapse. The right crank threads where the pedal screws in have completely worn away & the pedal fell out!

is the 7950 compatible, or do I need to buy anything else to fit my bike? I've read the other questions & I am concerned that I may need to buy a BB adapter? Could you clarify for me.

I can't see that you sel spare crank arms for the FSA Cannondale SI compact carbon crankset, which is a pity.

Answers

Answer: 
No Shimano chainset will be compatible with your BB30 frame unless you purchase an adaptor.

BB30 uses a 30mm spindle diameter with bearings pressed into the frame whereas all Shimano chainsets use a 24mm spindle diameter.

To fit this chainset to your frame the adaptor below will be required.

Answers

Answer: 
The BB90 bottom bracket is compatible with Shimano Hollowtech II cranksets and should not need replaced.

As the '2008 Madone 6.5' has a 90mm Bottom Bracket shell, it must be ran on the BB90 bearing; which will be fine with the suggested crankset.

Answer: 
No; the 7950 compact chainset runs the 24mm axle for a Hollowtech II external bracket system. It is compatible with the Ultegra and Dura Ace Hollowtech II brackets, as well as aftermarket alternatives like Hope or Chris King.
