How did Cannondale reduce the weight of the SI SL?

“Don’t pedal harder, pedal faster!” I was told by a Cannondale demo representative that Cannondale was able to reduce the weight of the SI SL by taking away some of the metal and mass at the end of the crank arm, beyond the pedal.

What’s the difference between the SI and The Hollowgram?

Standard crank puller and wooden dowel works. The Si isn’t a Hollowgram; The SL and SiSL2 are. Big difference between Si and SL is weight. As mentioned, the SL uses Hollowgram crankarms. Your crank will be a downgrade from what you currently have.

Why are SISL cranks called Hollowgram SI cranks?

The SiSl are hollow because they are formed with two pieces (clam shell). The walls are so thin that drilling them would not be healthy. Doing bike things. You do not have the required permissions to view the files attached to this post. Building up my first cannondale (caad9), and I picked up a pair of hollowgram si cranks.

What kind of crank arms does the SL use?

As mentioned, the SL uses Hollowgram crankarms. Your crank will be a downgrade from what you currently have. The 0PI spiderring rocks though. I’d swap that to your Si crank arms. The Si isn’t a Hollowgram; The SL and SiSL2 are.

What’s the difference between Hollowgram Si and Si SL?

Hollowgram would be the natural choice. But there are two versions to choose; SI Alu and SI SL Alu. Some who know the weight difference between these two crank arms? (Or know the actual weight of any of them)? I want to say the difference is 60 grams. The SISLs are around 580 grams with a 130 BCD and BB. Edit: I’m a jackass.

What’s the weight of a Cannondale Si chainset?

Cannondale’s range-topping SiSL2 has a sub-500g weight, but its prohibitive price limits its appeal. This new Si model forgoes the SiSL2’s CNC clamshell construction in favour of a patented 3D forging process, which allows it be lighter than the previous Si chainset without compromising its stiffness.

Which is the lightest Cannondale crankset in the world?

Cannondale’s engineers revised the Hollowgram crank design, enlarging the core pocket, trimming weight and retaining the cranks’ trademark stiffness. At a total system weight of 580 grams. The Hollowgram Si SL and BB30 system is the lightest production crankset on the planet. Moreover.
