THM yes, can you even consider ax-lightness (especially in the US?

BTW, I believe Pez's post states 448g including the BB. Could be wrong though.

I like it 8) Colour options on the anodised part? Blue doesn't do it for me lol. That spider looks a little over engineered, plenty of meat could be removed from that me thinks? I'm assuming this has a Hirth joint yeah? Like Specalized, Campagnolo and my dearly departed Sweet Wings?

Looks nice, but the weight is about the same as the new Red BB30. Which go for ~$375 on eBay. And durability is still a big ?.

he mentions custom spindle lengths to change non-drive arm position. this would keep the chainline the same. no, i dont think it would be worthwhile either.

My Red 2012 bb30 crankset is 415g including bb, excluding chainrings and bolts.

With the hyper-sensitive shifting ramps of the new yaw-type SRAM rings and the 11 speed trimless shifters I wonder how well these will shift with their off-timed chainring spider?

The anti-drop pin on chainrings is also useless with this spider arrangement.

What other cranks are available at or below 450g for crank, BB, and spider at or below $1100? Thats a serious question BTW, as I'm not really up on WW cranks.


Not quite below 450g but close enough to not warrant paying double.

Vuma Quad BB30 setup with chainrings, bearings, spacers, etc. - 574grams

(Note: 50/34 chainrings as a pair weigh 129grams. Just the arms/spider/spindle weigh 379grams to put things in perspective)

Vuma Quad BSA cups setup with chainrings, bearings, spacers, etc. - 596grams

Impressive, Mr. Ciamillo, but not enough to get me warmed up to wanting one. Q-factor is once again too wide for my liking and I won't even mention how little ankle clearance it offers us duck-footed cyclists (which I am to a mild degree). They don't look half bad though. May these cranks come to the market and beget many happy costumers! :)

Regarding the orientation of the spider.. the spider is removable and uses the same spline as the arm. The spider was simply placed on the spline for the photograph in the wrong orientation.

Regarding the weight, it will come down .. significantly I think; but I am more concerned about stiffness and robustness than weight at this point. The crank is one of the largest losses of power transfer. Testing is going well and weight will come off but I am not concerned about the Vuma weight that much because I don't know if the push to achieve that weight ultimately resulted in its being discontinued.

Regarding the Q and chainline.. On BB30 frames, there is a large spacer on the non-drive side so to reduce Q I just need the customer to verify that with their existing setup, a reduction in Q would not cause a clearance issue with chainstay and I am happy to shorten the non-drive spindle and spacer. This will not affect the 43.5 chainline for the drive side at all.

I know we are about weight here and pushing the envelope is what I am all about but on this project robustness and stiffness are my first priorities. I love working with carbon and enjoy applying the products and processing advice given to me by the folks at TCR Composites.. I will share some of the manufacturing process on this project shortly.

Thank you for all the compliments on the design. I will post some pics on a bike soon.

Thanks for the info and early purchase offer.

Will there be a Quarq spider?

"The crank is one of the largest losses of power transfer"- I'd be interested to see data on this, both comparative and absolute.

I have a batch of spiders being run and will show the 110, 130, and 135 (all a little different).

I am working on the power meter requests too but Charles is right.. not yet.

Yep totally agree.
