Handbuilt wheels with following components:-360 TubularThe 360 Tubular rim is a cornerstone of Zipp's heritage, and the 2009 version has an adapted shape to benefit from our findings from developing the 1080 and Sub-9. The changes have reduced drag at every angle in our test range while taking stiffness and braking performance to new levels. Such significant improvement is almost hard to imagine for a 394g, 58mm rim that has already won countless races from the Queen K to Alpe d'Huez, but we've made it happen.Wheels utilized in : 404Weight : 394gEffective rim diameter : 525mmAero Rim Width: 24mmRim depth: 58mmHole Count: 16/20OR-505 ClincherWe can't say enough about the 505 Clincher rim. Its M2CM construction can take the pounding of everyday training and the 58mm profile handles the pressure of competition with ease. If you're looking for the convenience of clinchers, the reliability of an aluminum braking surface, and a leg up on the competition, the 505 is for you.Wheels utilized in : 404Weight : 578gEffective rim diameter : 525mmAero Rim Width: 22.5mmRim depth: 58mmHole Count: 16/20Max tire pressure: 125psi-Rear Tune Mag 170 Hub:174 grams: few hubs can have a such weight with a top reliability.Available for Campagnolo 9 and 10 speeds and Shimano 8/9/10 speeds.Body : aluminium 7075 T6Cassette body : aluminium 7075 T6 shimano 8/9/10 speeds, Campagnolo 9/10 speedsAxle : aluminium 7075 T64 bearings3 spiral spring pawlsPawls track : titanium- Front Tune Mig 70 Hub :Body : aluminium 7075 CNCAxle : aluminium 7075 dia 17mm2 BearingsFlange Diameter : 37,5mmDistance flange / hub center : 35mmWidth : 100mmWeight : 72gUpgrading with Mig 45 and Mag 130, 150 or 160 is possible on request.Colors: black, blue, red, green, white, silver, goldSapim CX Ray black spokes are available (see category "Choice of Spokes" in the left column).
