Trek Superfly 9.8 SL Carbon 2015
If going fast is everything you’re looking for, choose the ride that powers Trek Factory Racing to the podium. Superfly is the pinnacle of cross country speed and efficiency.
Trek has done the research, and here’s what it tells us: 1) a bigger wheel is a faster wheel, and 2) one wheel size does not fit all riders. Conclusion: Ride the fastest wheel that fits. Trek has applied this idea to across there hardtail range, eliminating redundant 27.5 and 29 hardtail. Trek use the fastest 29 wheels on larger sizes (17.5 and up), and use better-fitting 27.5 wheels on smaller sizes (15.5 & 13.5) where riders may find it challenging to attain a proper fit on 29 wheels. No overlap. No redundancy. No more wheel size debate.
