Proterra Light i23 wheels check all the boxes for a fast and light alloy wheelset. The 23mm inner rim width provides the optimal tire profile for adventure road and gravel tires ranging from 30-42mm. Its open-cavity profile has been optimized to feature thinner walls that its bigger Proterra siblings while still remaining strong and resilient. Subdued graphics on a bead blast finish ensure these wheels won't clash with the colors of your dream bike. We didn't skimp on hubs either. Top-tier EZO bearings, a swift 6-pawl freehub and 3.7 degrees of engagement provide the look, sound and feel you expect of a high-end tubeless wheelset.
FEATURES:
- 23mm inner rim width with 28 spokes laced in a 3-cross pattern.
- 6069 aluminum alloy rim. TCS 2.0 tubeless-ready.
- Sapim Secure Lock 14-gauge alloy nipples minimize rotational weight while double butted 2.0/1.8/2.0mm J-bend spokes make replacement a breeze.
- Tubeless tape, Solid Strip and black alloy valves are preinstalled, making the wheels ready for tubeless tires the moment they arrive on your doorstep. The TCS 2.0 Solid Strip is a durable strip that lies beneath the tape, prevents it from sagging at the spoke holes, makes it easier to mount a tire and protects from puncture in the case of a broken spoke.
- Centerlock rotor mounts.
- Rear wheels are available with Shimano HG 11spd or SRAM XDR driver bodies.
TESTIMONIALS:
"The PNW provides the ultimate testing grounds for bike components, especially hubs. Mud, grit, rinse and repeat become the routine for 9 months out of the year. Nothing is safe from the intrusion of water, yet somehow my Proterra wheels have been trouble-free for the past year and show no signs of letting up any time soon. I'm confident they'll endure many more soggy miles and post-ride washes." - Tester Mark "Donny" Allison after thousands of miles.
