Proterra Light TCS 2.0 wheels check all the boxes for a fast and light alloy wheelset. Available in 23 and 25mm widths, the rims utilize an open-cavity profile to minimize weight while proven 6069 aluminum alloy provides the strength and compliance that has become synonymous with WTB rims. Subdued graphics, alloy nipples, top-tier radial bearings and a responsive 6-pawl freehub with 5 degrees of engagement provide the look, sound and feel you expect of a high-end tubeless wheelset. Gravel-ready 23 and 25mm widths feature 28 spokes. Both configurations are laced in a 3-cross pattern. 23mm rim width is ideal for gravel cyclists using 700 tires while cyclists who prefer a high-volume 650 setup will be better suited by the 25mm width.
