    Weight Saving 2x10 to 1x10 conversion - Scott Spark 10 Large
    Before: 22.36 pounds without pedals (10142g) - Great deal on ebay!!!




    After: 20.00 pounds sharp without pedals (9071g)

    White tires?! I know, I'm not really a fan either but at the same time I thing the only bike suitable with white is the spark...rc world cup...right? top of the line model...and found these for $80/pair brand new on ebay...I like the result. 435g/445g each one on my scale (Original tires were 606g each).

    Gripshift on the right (1x10) and Twinlock on the left. Much less busy cockpit and hassle free operation
    Grip**** XX White? yes....plastidip job.

    pulley set upgrade-14.5g/pair (original were old 22.5g) and carbon inner cage also upgrade. Original was 10.15g. New 7g

    MRP 36T 89.5g on my scale (spider with 26T/39T was 193g)





    So FYI: from were the saving is coming from:
    From Hutchinson/pair 26x2.15 (606g each) plus tubes (172g each) to Rocket Ron 26x2.10 plus tubeless valve 7g/pair - Total saving: 667.12g

    From 2x10 to 1x10 conversion:
    XX trigger left came out 96g without cable
    XX trigger right came out 92g without cable
    matchmackers out:23.60g
    XX Grip**** came in: 89.5g without cable
    XX front derailleur high mount clamp came out: 118.7
    cable plus housing (for rear shift) out: 31.1g
    From Spider 26/39 to MRP 36T: 103.5 less
    TOTAL weight saving from drive train conversion:
    Total before: 554g
    Total after: 179
    TOTAL: 375g

    just in case you want to upgrade your rear derailleur:
    From original inner cage plus orig pulley set to all new: 11.1g less

    Chain guide still to come: I will make one myself and will be under 30g all carbon,


    I hope you've enjoyed

    Has your chain come off without the chain guide? I have a similar setup with XO cranks with an MRP bling ring (28t). However I'm running a MRP Micro guide and wondering if it's necessary. I also have a Sram Type 2 RD.

    Can you post an "on scale" pic with pedals? I'm always keen to see ready-to-ride weights with digital proof, esp. in this subforum. :)

    Oh, BTW, great pics and I love the breakdown on the 1X weight savings. I realize it takes time to do that for us, so thx.

    Home made chainguide is ready: stainless bolt is heavy: Aluminum might shave about 8g....will?

    Pretty or not, its what your bike weighs. I always consider my bike weight with pedals, cage, garmin mount etc.
