cannondale hollogram crank question

[ninjanoir78]

HI,

on my evo I have cannondale srm on sisl crank (2015) and The crank arms are 170, I would need 175 and I could have a brand new sisl2 arms but not sure if I can fit 2017 sisl2 arms on my 2015 crank? I think the spindle is different now ?

thanks

The arms will fit, the spindle has not changed in that you wouldn't be able to fit the new arms onto it.

I think the spindle is different now ?

The only difference in the spindle was sometime in 2013, Cannondale introduced a 109 mm road spindle that eliminated the bearing shoulder on the non-drive side of the spindle. Again this does not affect which Hollowgram crank arms, but if your spindle is 2013 or newer, then more than likely you already have one.

ok but my srm on my holoogram sisl is about from my super six 2014-15 and also i have a si hollogram crank for caad 12, and the spindle is different as you said. my srm has a kind of stopper and the new si no...

The lobed spindle interface for the crank arms is standardized and remains unchanged since Cannondale introduced the Hollogram technology.

I have a Hollogram SiSl2 crankset with 172.5mm arms, looking to go shorter with 165mm arms, does anyone know if 165mm arms are available for the Hollowgram SiSl2 crankset? Any suggestions for other options for arms to keep the crankset? Really like its looks and weight, not looking to change brands.

Thanks!

When I had to warranty my 165 arms they said they couldn't get replacement 165. I don't know if that's because they stopped producing altogether or do it in batches a few times a year. I recall that 165 isn't offered by itself but only on women's bikes or something like that.
