    Which chainrings fit HollowGram SL cranks?

    I have a 2010 Flash with the HollowGram SL cranks. I am a little in doubt which chainrings it is I should get for the cranks as I can understand that only one type will be compatible. Can someone tell me if it is this set that matches the cranks:

    Thank you

    to make those chainrings work you'll have to get the SRAM XX Cannondale spider that fits the hollogram cranks just go to your Cannondale dealer and order it it's about $100 the spider those SRAM XX chainrings come on is a specialized for their crankset and won't worky on cannondale.

    Thank you for your reply.

    So if I want some chainrings that fit directly on the crank and spider I have (see picture), - what is it then I should get?

    yes the SRAM XX chain rings and the SRAM cannondale hollowgram spider is what you need because the SRAM chainrings are 120bcd

    I am looking to buy an extra set of chainrings, but in doubt if I can buy loose SRAM XX chainrings or whether it needs to be the set shown including both rings and the spider?

    Further, are there other brands of chainrings which fit on this setup?

    Thank you

    As for other brands, I don't know what else is out there. My understanding is that XX uses a non-standard bolt pattern. To buy standard chainrings you don't have to buy the two rings plus spider... You just need the chainrings due to the fact you already have the spider and the bolts. I think initially the main reason people bought the spesh spider and chainrings was 1. It was impossible to find thechainrings by themselves and 2. You needed specific bolts that you couldn't get separately but came with the whole package.

    Yes, you can buy just the chain rings. You could try Robert at r2-bike.de.
    Also he has new after market one's from FRM and soon to be Carbon-Ti in full titanium and carbon/Alu. I have order a set CARBON-TI carbon/Alu 42-26t.
    You could also ask Mattias from "Experimental Prototype" I have order some from him too.

    getting the individual XX chainrings is next to impossible i just bought the chainring and spider set up and eBayed the spider to offset the cost.

    rotor rings http://www.cart32hostingred.com/cgi-...odid=153391360 has em' for SRAM XX too.

    Part of the advantage of going to XX is the shifting. I'd be hesitant about using after market rings.

    Agree but Carbon-Ti have come up with something similar to help the fast/smooth shifting up front. Take a look.

    It might work but I haven't tried it (yet)
