This 2021 SCOTT SPARK RC 900 Comp mountain bike is A 29″ carbon frame complete suspension cross-country bike with upper mid-range components. I am a NICA rider and have loved this bike through high school; it has been taken care of very well and washed frequently. Its only mechanical error is that the front lockout shifter is broken and needs a slight fix, but I have not gotten around to it. I'm selling it as is with that one defect; everything else is in perfect working order. And I would recommend it to anyone, especially high school racers,
