I had thought for a second that SCS would live on for their road bikes, but it looks like the 2017 Venge is also 142 thru. I've heard mixed reviews on the effectiveness of the alternative hangers for thru-axle bikes like the Diverge that relied on SCS from the factory. Pretty sure my QR Crux with a new hanger will work fine with regular QR Disc hubs - which is the path I will be going down when I finally upgrade wheels.
It's basically a 135mm hub spacing w/ a 130mm effective cassette spacing (think proprietary hub, but "open" if anyone else wants to make them). If you want to run normal 135mm or 142mm (QR or thru) disc hub you need a new rear mech hanger, and your SCS wheels are no longer compatible. I've heard mixed reviews on the new hanger when it comes to thru axle bikes that were originally SCS, but I don't have that issue as I have an alloy QR frame. For instance apparently the thru axle non-SCS hanger doesn't actually move the rear mech, but just moves the thread end of the axle slightly inboard, meaning it no longer threads all the way in, and you may have to redish a new wheel to get it centered in the dropouts. The people worst bit by this are those that invested in fancy Roval wheels and the like for their SCS disc Tarmacs, Cruxes, etc. - those wheels are pretty much dead as far as moving them to future bikes is concerned without rebuilding on different hubs, or machining some custom end caps (hopefully these become a standard offering from S). Confusing thread on it here: http://forums.roadbikereview.com/specialized/scs-wtf-345626.html Article on it here: http://www.bikerumor.com/2015/10/19...-road-bikes-gain-thru-axles-but-theyre-weird/ Moving forward anyone w/ SCS should probably switch hangers and trash their old SCS hubs when building new wheels so that going forward they will work with future frames. Disc has really screwed up the whole "neutral wheels" thing. Now that your '17 Crux might work with your nice XC 142mm wheels, time for an industry wide switch to boost 148!
thanks for many words, but what does SCS stand for? Ok, ok I'll click something and find out. Well, I probably won't but you don't have to add anything for my benefit.
