This is a 17.5" (Medium) carbon 2013 Scott Spark RC 900; it's a pure XC racing machine. It's been updated with an SLX 1x12 drivetrain, an SLX 1x crankset, and brand-new ZTTO hydraulic disc brakes (installed 10/20/26). The rear shock is functioning well (remote lock-out works great) but it does bottom out prematurely; it's not an issue when you keep it in lock-out mode (racing mode). This is reflected in the price. It's hard to find a bike of this level with these parts for this price.
The highlights:
- 17.5" (Medium) Scott Spark RC 900 carbon frame
- Fox / Scott NUDE rear shock (100mm)
- Rock Shox SID front fork (100mm)
