Most of the focus on rim specs tends to be on weight alone, often leaving the much larger effect aerodynamics has on speed and energy overlooked. The Radiant, based on the speedy Rolf Prima Vigor alloy rim design, feels considerably faster than other rims. With a 32mm depth, this rim is at least 6mm deeper than most of the standard competitors, giving you a stout and stable profile ready to charge through any headwind.
All Astral rims are Tubeless Easy: the rim profiles have been optimized for easy tire mounting with a deep center channel or "drop channel" and bead seat diameters dialed in for ease of inflation and secure mounting
These rims are drilled for external nipples, which makes truing easier as the tire, tube, and tape do not have to be removed.
This is the black with machined-sidewall rim brake version available in 20 and 24 spoke hole counts (disc specific version also available).
