PEAK 4550: A New Milestone in Performance Cycling Wheels

Exceptional Handling. Ultra Lightweight. King of the Mountain.

Princeton CarbonWorks announces their all new PEAK 4550, developed in conjunction with the top cyclists in the world; a lighter, stiffer, stronger, and more aerodynamic solution directly targeted at world tour and grand tour racing (and of course, ALL racing and riding…)

Available in every configuration, (tubular, tubeless ready clincher, rim and disk brake) the PEAK 4550 set weighs as little as 1071g in tubular rim brake guise, with standard tubeless ready clincher versions weighing 1297g for rim brake and 1348g for disc brake.

Princeton CarbonWorks PEAK 4550: A New Milestone in Performance Cycling Wheels

Exceptional Handling. Ultra Lightweight. King of the Mountain.

Princeton CarbonWorks announces their all new PEAK 4550, developed in conjunction with the top cyclists in the world; a lighter, stiffer, stronger, and more aerodynamic solution directly targeted at world tour and grand tour racing (and of course, ALL racing and riding…)

Available in every configuration, (tubular, tubeless ready clincher, rim and disk brake) the PEAK 4550 set weighs as little as 1071g in tubular rim brake guise, with standard tubeless ready clincher versions weighing 1297g for rim brake and 1348g for disc brake.

Development priorities were to create an all-around race ready wheel with exceptional aerodynamic characteristics and the strength and stiffness to transfer high wattages to the ground. The
performance characteristics of grand tour riding are perhaps the most difficult to synthesize in a single wheelset. Riders need a wheelset that is light and responsive for the climbs. On the descents, they need predictable and sharp handing. In the valleys, the wheelset needs to be aerodynamic and impervious to crosswinds. And above all of that, the wheels need to hold up to thousands of kilometers of full gas racing.

PCW’s standard non-drilled tire bed facilitates a stiffer outer rim and transfers some material away from the tire bed to other critical areas in the wheel, helping to keep wheel weight low while maintaining high stiffness values.

    Wheels are as advertised. Fast, light and seemingly impervious to cross winds. Only a handful of rides (rim brake set w/ Carbon Ti hubs), but I can already feel the magic. Looking forward to more rides. Team has been super responsive from a customer service perspective. Definitely getting another set on my next build. And they look amazing!

    I picked up a set of Peak 4550s (Carbon Ti) after riding for about 6 months on the Wakes 6560s. I have been able to put about 1500 miles on them and they are my preferred wheelset. They are easier to handle in winds and generally more agile. The trade off is about 5-15 watts of drag in the 18-25mph range. In similar rides with similar power output my average speeds are in the range of 0.2 to 0.5 mph less. Though, in rides with long climbs and descents, the difference in average speed is less. My Strava times have also been better on descents with the Peaks. They are easier to handle at speed, especially with swirling winds.

    If trying to decide between the two, I recommend the Wakes if predominantly riding on flats and high wind (swirling or gusting) is typically not a factor. For more varied terrain, especially with larger climbs and technical descents, the Peaks are a better choice. Either way the wheels have a ride quality that sets them apart from other brands. I highly recommend both.
