Still pretty fresh outta the oven, Ciamillo continues to tweak the Gravitas crankset. The Revision 3 design has longer pedal ends to make it even stiffer. The original design used a shorter alloy pedal end, but Ted Ciamillo said that didn’t provide the overall stiffness that the carbon tubes could provide.
According to Ciamillo, the original design’s sockets would yield to the force of the tubes and could end up wallowing out a bit over time because there wasn’t as much surface area supporting the carbon as he liked.
The new design provides 41mm of contact area, up from 25mm on the originals. The four pins that help secure the parts (two on each end) have changed from a hollow design to a two-piece, lipped design that better prevents movement and transfers forces better. These changes ended up effectively doubling the system’s stiffness.
Claimed weight remains exactly the same at 395g for a 172.5. The original design let the carbon tubes extend all the way past the pedal’s insertion point. The new one stops the tubes just before the pedal hole, offsetting the additional weight from the longer end piece.
It’ll be offered in anodized black and powder coated white, which will add a few grams (these are a 175mm and came in at a claimed 415g). Like his brakes, the ends are still anodized prior to powder coating.
The white ones shown here are a customer’s crankset, so they’re shipping now. Retail is $899, add $50 for white. They can also anodize any of the alloy parts, excluding spider and spindle, any color at no additional charge. Available in compact and standard in either BSA24, BBright or BSA Adapted 30 (longer 30mm spindle) and BB30.
