This wheelset is built for fast training and racing with hills in mind. The Altamont Lite rims are tubeless compatible, 19.8mm inner width for that wider profile tire, and 25mm deep for added strength and a semi-aero benefit. Boyd makes great rims, period! For hubs we suggest a black color in either White Industries, DT Swiss or Chris King, but other hubs and colors are available. Spokes are black Spaim D-Lights, and laced 2 cross front and 2x non-drive, 3x drive side rear.
