Zipp’s ultimate aero weapon is faster than ever, thanks to their proprietary Total System Efficiency technology. With TSE, the 858 NSW Carbon Tubeless Disc-brake wheels features a tubeless and hookless rim profile for seamless tire interface and huge drop in weight. The wheel’s internal width is 23mm, ideal for running wider tires with lower pressures for decreased rolling resistance, and the Carbon Internal Reinforcement (CiR), creates a rim that is 10% lighter and just as strong as previous wheels. At the center of the 858 NSW is the Cognition V2 Hubset engineered with the Axial Clutch V2 mechanism for quicker engagement and lower friction as well as improved durability. The result is pure speed, especially for triathletes, time trial specialist, and any other speed freak.

Everything was great. Was waiting for the SL9 to release since the first leak. Going from a SL7 was night and day.
Also Sierra Bicycle Supply, was amazing. Will be shopping here plenty more. The service they displayed was top tier, from the order placing online all the way to the delivery.

Literally EPIC
Fast shipping and perfect frame set as described. It's literally the lightest built MTB I've ever felt. My wife will be smashing on it at this year at the Leadville 100. LFG Thanks guys!

Exceptional Wheels
The CLX III are exceptional I was a little apprehensive about buying them having ridden the Enve 4.5 but you feel less crosswinds and their lighter and spin fast. The spokes seemed to offer a lot of dampening vibration. Win win in my book.

After many years I wore out my derailleur gears. Since I ride on my wind trainer daily, I needed to get up and riding again. Riding us part of my cancer therapy. Replacing the gears was a quick and easy way to fix the problem. Cost was fine and the delivery was fast. Thank you.
Got this for my kids bike. He does XC racing. Has been riding in dry lose dirt, wet conditions. Lots of climbing and some downhill. He loves them. Shipped fast and in sexure packaging. I would definitely buy again.
Heard a lot of good things about this tires put them on my commuter. The roll much faster than the schwable energizers on it. Puncture protection only time will tell.
