On another note, your signature may need an amendment.

The cranks look fantastic! I don't have nearly the budget necessary to purchase a pair, but I'll enjoy the pictures for now.

Here's the email I received:

Gravitas Crank Spec Revision

70 gram mass reduction! (new test weight at 378 grams)


The Ciamillo Gravitas Crank is still in development and over the next few weeks we will continue to test the design and make improvements. However, we have recently made some radical changes to the core geometry and material which has allowed a mass reduction of an incredible 70 grams. Testing and tweaking was not expected to produce such huge mass reductions and we are excited to say that we are testing at 378 grams for arms, spider, and spindle. This new design is on track to be the lightest crank in the world.

If you haven't got your order in yet, please know that there are a few sets left at this special pre-order price. If you have reserved your set, thank you. We are progressing well with testing and expect to begin shipping in about 5 weeks.

FYI, that was from the email, I'm not particularly thrilled about that appearing as my quote because they're not my words.

Speaking on behalf of detractors I see. I sincerely hope the new Ciamillo cranks reaches production status and at that mentioned weight, but I also know how difficult it is to actually manufacture a crankset that light, let alone even lighter. As proven by Zero Gravity's earlier attempt, it's exceedingly difficult to release an ultralight, reliable crankset onto the market. But to say it'll be the lightest crank in the world is overly optimistic as well as unrealistic, which is also spoken from personal experience. What cranksets have you designed or made, Mario Jr.?

I think this thread has been a little confusing. The original post claims 454 grams but has no information on what that includes. What the 454 grams includes is very important in assessing how this crank compares to the competition. Later it is claimed that this weight includes a BB but no details on what kind of BB. All this is kind of fishy.

Now we are to believe that the crank is down to 378 grams and that it has lost 70 grams in approximately one week. That would assume that the original weight was without a BB. Sounds fishy.

Take a look at what forum this is on, it is called “Weight Weenies”. We are of course interested in more than just weight but to throw around misleading weights is just not going fly.

If the weight of the arms and spindle is truly at 378 grams, that is competitive with other light cranks but does not come close to some of the other lower weight competition. Both the THM Clavicula crank and the Ax Lightness crank weigh about 336 grams for arms and spindle. The M3 is about 370 grams but is more versatile and has more room for your ankles.

So this looks like a promising prototype and if the finished product is sold at a competitive price, it should be well received.

It is hard to see from the pictures the shape of the arms and if they give much clearance for ankles. It looks to me that the center of the crank sticks out and would be an ankle buster. But maybe we just need better pictures. I just think that this is not a good way to introduce a crank. Kind of half ass.

Wow, easy now. (I have actually moulded one out of paper maché that was pretty light. :wink: )

I just don't get the point of needing to show your (very nice BTW) crank as I'm sure there's even lighter cranks out there? At least my paper mache crank was, but there's a reason for that one not being produced, just as well as I suppose there's a reason your's isn't. Maybe too light?

Not sure if 70grams was saved this way but removing the material between the spider arms would save some weight. May even save a few more grams with a thinner spindle ID and boring holes in the spindle splines.

So, Mythical, how much for your crank, my fellow fiend, I mean friend? :twisted:
I have a wish list. :twisted:
But, no money. :(
Yet. :twisted:

Can someone answer a few questions.
1 , What BB's will be available ?
2, Can we have the total weight including BB ? No confusion then .
3 What sort of testing is being done i.e. climbing sprints out of the saddle etc etc?
4, Are the riders testing the cranks of various sizes?
5, I Climb always on my 53t. Is this crankset going to cope with climbing in the harder gears?

Thanks artray

ps prendrefeu .Im not stalking you I keep posting the next post to your's

Yes, I am optimistic. We have a new material and geometry for the core and we will be looking at further gains (mass losses). For some reason I find the greatest improvements post launch.. just to be clear, BB (bearings, or adapters as the case may be) were not included in my initial weight report and are not included now. And I did not say that this would be the lightest crank in the world, I said we are "on track to be" ... probably excitement about the results so far and the other changes I have yet to try. I am a bit overly optimistic and yes, there is a difference between being the lightest in the world and the lightest truly robust crank in the world .. the crank must be robust and light .. just like our Gravitas road calipers.

Laff. I'll have to show Christian this picture next time I see him and see if he remembers taking it.


Man, C-Fos looks a little like Cav there. I had to do a double take...
