Princeton CarbonWorks Peak 4550 Evolution II

Light enough for the climbs. Versatile enough for every road. The Peak 4550 Evolution II combines Princeton CarbonWorks' variable-depth carbon rim profile with a lightweight, modern road-wheel design. It is built for riders who want one premium wheelset for mountain routes, fast group rides and long gran fondos.

What makes Evolution II different?

• 45–50 mm variable-depth rim profile balances aero ambition with a versatile all-road-racing character.
• 22 mm internal rim width and up to 32 mm external width accommodate modern road tyre setups; confirm compatibility with your selected tyres.
• 390 g quoted rim weight and a 1,200 g lightest quoted wheelset with Tactic Racing TR01 hubs. Actual complete wheelset weight depends on hub and configuration.
• Hooked, hole-less tubeless-ready rim bed designed for tubeless use without conventional spoke-hole rim tape. Always follow both tyre and rim pressure limits.
• Alpina Hyperlite spokes and premium hub choices.
