We first spotted WTB’s new Frequency UST tubeless rims at Interbike, and now we’ve got the full spec rundown and some photos.
Aimed at the custom wheel builder segment, they’ll be offered as rim only in 26″ and 29″ sizes and 19mm and 23mm widths. Weights range from 390g to 530g. As the icons below indicate, there are a lot of features to boast. Click through for details…
The rims use 4D drilling, which angles and aims the spoke holes to eliminate any bend or undue stresses on the spokes, pointing them straight at the hub. They’re designed to use regular spoke nipples and spokes, so they can be built to just about any hub with any traditional spokes. The rim bed has their “On-Ramp” shaping to help direct the tire bead into the UST socket.
WTB’s I-Beam construction has been around for a long time, and it’s here, too. Essentially, it’s a vertical wall inside the rim to help keep it laterally stiff.
The Unbendium Bulge is a bit of extra material on the sidewall to improve “torsional, radial and lateral strength.”
The rims retail for $75 to $80 each.
