Cannondale Hollowgram SL crank weight?

[dawgcatching3]

I just purchased a Rize 2 as a lightweight trailbike frame, and it comes stock with a 68mm BB and XT cranks. I was considering removing the adapters and going BB30 (which is OK on the Rize, as it has an alloy BB shell, not carbon). Anyone weighed the Hollowgram SL cranks in 3x9 (probably 22/32/44) with the spindle? I am trying to figure out how much weight I can shed over the XTR cranks (797g on my scale with everything).

with everything.. (bolts, spacers, bearings, spindle etc) - probably around 600-625g or so depending on rings. My 2x9 with FRM 42t and all bolts is 575.

My LBS has a Rize Carbon 1 in the shop. Looks so sweet with a flat bar. If only my country would justify such a bike... The bike is pretty light, considering the travel it gives.

Please post pics when your build is ready!

Can i add granny to a double Hollowgram SI SL ????

Im searching the net for a 3x9 but i only found 2x9....

[Tiffster]

I think the double ones are labelled double for a reason - IE there 2x9 only.

you can change the spider for add the granny ring

and transform a 2 x9 in a 3 x9

And the light wieght of the Hollowgram SI SL is definaly going to be there..

But our trails we really need a granny thats why im hopping to get the crank with 3x9...

One more thing

When using a 2x9 (44-29), going up hill, the lightest, what would be the closest to when using a 3x9 (44-32-22).

[kenz76]

29-34 is similar to 22-26.
so riding 1-1 with double, feels like 1-3 with triple.

[Ladeira]

1-3 on a tripple isnt that bad... Maybe ill give it a try on a double

About weight savings can you guys tell me the difference of a double and a tripple?!

But is it working well to remove the adapter? Thinking of doing this on my SystemSIX that I don't have any warranty on.
