Trail bikes with under 140mm of travel are fun mountain bikes of choice. When it comes to carbon wheels pairing a bike with the right tool for the job is paramount. These trail bikes, or hardtail bikes, need a good selection of rubber, but also need to maintain their playful nature, and this is our answer. Bring on the 27mm internal width of The Faction. A carbon rim that punches well above its weight in overall strength, but rolls as you'd want on a trail bike. Lightweight and surprisingly strong!
