If you want the best crank get a Hollowgram. If you can't get the SISL, the older SI will do. You should be able to find one for ~$300 on eBay. Not sure if this link will work, but here is one to completed listings: http://www.ebay.com/csc/i.html?_sacat=0 ... te=1&rt=nc" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;


To diverge from the topic for a moment, I'm just trying to figure this out: I always see lots of recommendations for the Cannondale Si SL crankset. Light and stiff, I get that. Am I right that it Cannondale specs it with the same chainrings that FSA uses on the SL-K that is snubbed so frequently?

Back to the question on hand, I'm guessing from the responses so far that a SRAM crankset will play nice with all the Shimano stuff on the rest of the bike.

The FSA rings are ok, it's the cranks themselves that are rubbish.

I use the Wheels Manufacturing adaptor with Dura Ace cranks now, works perfectly. Before that I had BB30 FSA cranks that broke.

I disagree with 54x11 and find the opposite (will wash my mouth out for defending FSA after this), in that their top line cranks aren't too bad.

Their rings though are really not much cop. Their BB even less so.

To be honest, I have no experience with the Hollowgram cranks that came with the FSA chainrings. All the Hollowgram's I have came with the Mk rings. Those aren't bad for weight:stiffness. However, you can always pick your favorite chainring to use with the Hollowgrams. There is a limitless number to pick from. You buy those cranks for the crank, not the chainrings that come on them.

I'm looking for a BB30 to Shimano adaptor. What is a good solution out at the moment?

I'm not sold on the Wheels-Mfg because of the way the load from the BB spindle is applied to "narrower" bearing spacing. Correct me if I am wrong here.

I'm typically looking for a PF-30 type solution which will work in a BB30 system.

Have Shimano produced a pressfit adaptor for BB30 in the 9000 group series?

I agree, the current FSA Cranksets both SL-K and K-Force Light quite good; finish, fit, and durabilty are a number of steps up from that of prior generations.

I find the shift performance of the chainrings to be good, but not so much the finish of the teeth, which causes them to be a bit noisy in the beginning

Logo's / striping are questionable

Praxis works has the best option for PF30/BB30 to Shimano http://praxiscycles.com/pages/conversion" onclick="window.open(this.href);return false;

Why the HT2 tool grooves on both the NDS and DS when installation only seems to use DS?

I agree with the Hollowgram suggestion.

I run older Si model Hollowgrams on two of my bikes and am very happy with them. I do have FSA rings on there, as that is what they came with. I think the FSA rings are fine and have had no issues with them.

I think I paid about $200 for the second one about a year ago.

I just installed the Praxis BB conversion in a Super Six. Very straight forward and they have some very nice bearings. When I run DuraAce, I have always found the shifting so complete with the Dura Ace crank. Now I have run many Hollowgrams with different version of chainrings, nothing comes close to the Dura Ace. Now the 9000 is so close to Di2 that I wouldn't spend the extra $$$ on Di2 again.
I would recommend the Praxis BB30 conversion, install the Shimano crankset and you are done.

If that's what you did, you might as well have gone proper BB30.

Come on people, post more.

I'm begining to think this ghastly thing is the best solution of them all -- solid and permanent:

What is the Pro peloton using for adapters? There used to be a good Pro-Tech thread going on this forum.

Hey guys,
Glad you're liking our BB30/PF30 BB for Shimano cranks. It will be OEM spec on a bunch of brands next year.
Let us know if you have any questions as we just wanted to make a proper BB and not just a plastic spacer.

Here's the spec page with explanation of our unique design.
