The Peak 4550 Evolution II is Princeton CarbonWorks' climbing-focused road wheel, built on lessons from the Wake 6560 Evolution II. It widens to 22mm internal and 32mm external while rim weight drops to 390g. The lightest build, on Tactic Racing TR01 hubs, weighs 1200g.

The tyre bed is hooked, non-drilled and tubeless ready. It takes tubed clinchers or tubeless tyres with no tape, and Princeton sets no tyre pressure restrictions. Princeton's position is that a hooked rim is the safest and fastest option for road riding, and that hookless designs bring tyre choice and pressure limits.

All rims are pre-balanced to match the included tubeless valves. Builds use Alpina Hyperlite spokes with Sapim SecureLock alloy nipples.
