I have a nice high-end 29er Spinergy Xyclone wheelset with PBO Fiber spokes. Front hub is 100x15 and rear is convertible between 135QR or 142x12 (both included). These are NOT BOOST spacing. Recommended for use with 10, 9 and of course Single speeds. It was on my backup bike for a few seasons and used for fire road training to build my base endurance. I really like how quickly it helps me accelerate and maintain speed. This is due to the great Hadley hubs and lightweight PBO spokes, which suspend the rim similar to how a tennis racket is tensioned (strong, light, and compliant). Sale includes the thru axle, QR and three extra spokes. Have it posted on CL for $325, but will take less here if anyone is interested. I live and work in the Mission Viejo area.
