    Lightest shift cable setup (Sram X.0)

    I have a sram x.0 rear trigger shifter and derailleur with stock shift cable and full length housing. I have to run full length housing on my frame so hopefully there will be room for weight loss with lighter parts.

    I am keeping the x.0 shifter and derailleur, but am wondering what small parts can be swapped out for lighter parts.

    I'm looking for info on bolts, springs, pulleys, any pieces of the shifter and derailleur.

    I've also seen info on powercordz, but to tell you the truth, I haven't understood everything about them yet. Are they the lightest shift cable? What's the lightest setup to make them work well (cable, housing, liner if needed, any special ferrules).

    Also curious to know how much weight I am looking at losing over the stock stuff.

    On the Xo trigger:

    Swap the bolt that retains the lever to an alloy or Ti one.
    Swap the clamp bolt to Ti or alloy
    Fit Powercordz


    Xo Rear mech

    Fit carbon jockey wheels
    Change cable pinch bolt to alloy


    All this should save about 30grams

    The lightest shift housing out there is made by Vertebrae in ceramics, but it's $140 for the housing, and more if you want a full housing setup. You pay for what you want.

    I'm running the same X.0 Trigger/rear shifter setup. Tiffster - where's the best place to get the alloy or Ti bolts for those and the carbon pulleys? How much of a weight savings would one see with those upgrades (without changing to the powercords)?

    jockey wheels:

    They save 20grams.

    Alloy or Ti bolts - get them dependant where you are in the world really... They save about a further 5 grams.

    but vertebrae is said to weight 52g/m, while alligator i-links are 27g/m...

    Do the carbon wheels hold up as well is the stock plastic wheels?

    They hold up better, carbon is tougher than plastic - no wear on mine yet...

    Do they shift exactly and just as quietly as stock?

    a bit better in my opinion, they have a tiny tiny amount of float which makes shifting a bit better for me. Definetly no louder than stock - probably quieter actually as carbon absorbs shock better.
