RaceFace Cinch Axle w/Hollowgram?
Moderator: Moderator Team
Has anyone here taken a look at the RF Cinch axle, and compared it to the Cannondale Hollowgram spindle?
Based on pictures, they look very similar. Does the RF axle fit in a Hollowgram crankset?
I have a Stages/SiSL, and want to be able to swap it between my BB30 race bike and my BSA Santa Cruz TB LTC.

So the very obvious weight weenie question: Which one is lighter RF Cinch or Holowgram axle?
RF spindle is compatible w/ hollowgram Si. But the Q factor is pretty big. 171mm.

Always confuses me why this type of question seems to keep reappearing. How is it that nobody understands that there is no offset with a hollowgram spider on SISL arms? In simplest terms, this means when attempting to employ hollowgram crank arms in a non-BB30/PF30 application, while a longer spindle makes it possible to install the crank, all it does is push the chainrings (or chainring in the case of a 1X drivetrain) further away from the frame, thus further away from the best chainline?

Re qfactor, surely the 134.5 mm RF axle will present a smaller q factor than the 137 mm Cannondale axle for SiSL2 ?
Compared to BB30 on a Cannondale with a 132mm axle the RF option is only 2.5 mm wider ... Or am I missing something!?!

Answering my own question, the Q factor for Cannondale Hollowgram is rubbish now I look at the closely. Nice and light though!
May I add a question to this topic?
I am currently riding a Scalpel 29 with Bb30 bottombracket and SISL2 cranks.
I am thinking to switch to either a newer Scalpel, BMC Fourstroke or Scott Spark.
The latter two come with bb92 if I understand right. Since I not only like the crankset itself but also the powermeter installed I would really like to re-use the cranks.
The Spark comes in a version, that is equipped with a Cinch crankset from the manufacturer.
With the powermeter came spacers to move the chainring 3mm closer to the center of the frame if needed.
Do I understand it right, that in principle, it should be possible to simply swap the crankarms and adjust the chainline if needed?
Are there numbers how much the q-factor between hollowgram and cinch cranksets differ when they are installed on the same axle?
Cheers

Is your current Scalpel a 73mm or 83mm wide shell?
If 73mm shell, the current crankset is designed for a 49mm chainline. You will need your chainline 3mm wider on the Spark and Fourstroke and 6mm wider on a new Scalpel.
If 83mm shell, then the current chainline should be 55mm. That is the same as the current Scalpel and you would need to narrow it 3mm for the Spark and Fourstroke.
The SISL2 arms will attach to the Cinch spindle. You could also just slide your SISL2 spindle through the bottom bracket if it comes with a Cinch crankset. Either way you will need to play with spacers as the bottom bracket widths differ and the depth the cranks go onto the spindle probably differ.
In short, any option will work. But best to get the bike in your hands and have a few bb30 and chainring spacers on hand for trial and error.
