    Anyone see the new RF Next Cranks?

    pinkbike link

    425g for a set with a direct mount 28t chainring? That's nuts. My XTR 980 setup with a single 32t chainring is probably close to 600g or a bit less, so these are 175g lighter?!?!?!?


    Do want.

    definitely on the want list. love the versatility of having the option to go direct, single, double or triple (which i'll probably never go back to).

    I just picked up a set of RF SixC cranks for my Chili, debating on selling them and ordering the Next SL.

    Looks like they have a different interface between the cranks and the chainrings than SRAM does; so you can't use the MRP Bling Ring Chainrings or the Wolf Tooth Direct Mount Chainrings. Both companies will probably build chainrings that fit the RF cranks.

    My questions:

    1) Are the RF cranks lighter than the SRAM XX1 cranks? (XX1 cranks are cheaper than the X0 and are the same thing.)

    2) Which costs less?

    I can guarantee the SRAM cranks are cheaper. Msrp on my SixC cranks was $659.99.

    B, what config was that price for? the arms/bb and 3 rings?

    I think the PB article I linked shows the prices.

    "X0 with 175 cranks and [34T] bling ring = 538 grams." From this: Superfish 110 Conversion | ridingagainstthegrain

    You can save 29g on a 34T and add more "bling" by going with Sram Spiderless

    If you do a comparable setup (i.e. 28T) with the lighter Absolute Black chainring then you still weigh 499g* which is still a 74g more. On the bright side, this setup would ONLY cost around $400.


    *499g = 538g X0 with 34t blingring - 85g for 34t blingring + 46 abs black 28t ring

    Arms & 24/36/bash. BB is not included. I'm running a 1x10 with the Straitline guide so I didnt even need the rings or bash.

    From the PB article:
    ...use a 30mm diameter aluminum spindle made from an alloy that only recently became available for commercial use and claimed to be 20% stronger than 7050 alloy.
    More questions:

    1) What is this new alloy?

    2) Are there threaded BBs that support a 30mm spindle? (Most threaded BBs are 24mm I think.)

    It looks like you can't change out the single-ring option (maybe the others?) without taking the crank off? That would kinda stink compared to the move towards being able to swap out rings, in fact I got my 2nd ring in the mail on the way for my XX1 cranks I just picked up (and rode the last few days, nice cranks). I'm guessing the retail on these new cranks will be at least $1200?
