PROGRESS Airspeed 33 Disc road wheel set 12 x 100 / 12 x 142 mm

Features: - NEW Patented HI-TG Nano Resin System with multilayer High Modulus Carbon. Resist heat and deformation of continuous braking up to 270ºC. We tested 380ºC at the video we show on our website “where is the limit” - Crashed wheels! In case of bad luck, PROGRESS supports you by offering replacement rims for half the regular price during 1 year after purchase. - AIR+PLUS High speed technology with optimized aerodynamic efficiency and less drag. Lateral wind is no longer a problem anymore thanks to the new 28mm wide U-shaped carbon rim. This design allows the use of wider tires without negatively influence on the wind flow, more tire volume, lower rolling resistance and better handling in crosswinds condition. The AIR+PLUS is successfully worldwide race proven and wind tunnel tested. (Check AIRBUS GST results) - Extremely durable hand built wheel. High durability and high precision. - Rod Hub’s with 12mm thru axles. - VEKTOR is our very strong aluminum hub for every day riding and almost free of any maintenance. PAL-TECH assures 100% parallel bearings for less friction. Aluminum free hub body with extra strong and classical 4 pawls system. - TLR Tubeless Ready We’re using most common rim bed design. Its advantage are excellent rolling resistance, fewer punctures and easy mounting tire. Specifications: Rims: - Available for Tubeless Ready - AIR+PLUS carbon rim U-shape design with excellent aerodynamic efficiency - ECS Reinforced at the spoke holes for high spoke tension. - Carbon UD matt finish with high resistant transfer graphics. - 3M Reflective O logo. Profile: - Profile: 33mm - External width: 27mm - Internal width: 19mm Hubs: - Vector Disc Center Lock hubs high precision machined in aluminum. - PALTECH 100% Bearing alignment with low friction. - 4 Pawls system and tool free maintenance. - Freehub body in aluminum Spokes: - PILLAR PSR double butted Straight Pull 24 spokes. - Hand Built with alloy nipples and secure lock. - Quick release/axles: 12x100/12x142 - Weight: Set Tubeless Ready: 1.420 gr - Limits: Recommended rider weight limit: 110 kgs - Recommended tire sizes: 23mm to 32mm Options: - Shimano HG freehub - Sram XDR freehub Technology: AIR+PLUS High speed technology: - When you race 40km/h your wheels are spinning double 80km/h, hard cross winds are capable to throw you from the road. - With our wheels lateral wind is no longer a problem anymore thanks to the extra wide and latest U-shaped design. - This design allows the use of wider tires without negatively influence on the wind flow, more tire volume, lower rolling resistance and better handling in crosswinds condition. 23 to 28mm tires are seating totally integrated into the rim shape and do not offer extra friction. - This shape has high aerodynamic efficiency in accordance to latest scientific findings from wind tunnel testing’s. - Comparing to regular V-Shape rims we reduced drag and crosswind drag coefficient by more than 30%. PSG (Perfect Spoke geometry): - Every Progress Wheel is designed for his specific operation purpose. Our choice of rim, hubs, spokes and lacing pattern isn’t just a coincidence. - We strengthen rims at every spoke hole on each rim we develop. The spoke hole and nipple seat is perfectly aligned with hub and spoke angle. - This creates a perfect spoke geometry which allows us to use high spoke tension by an evenly and equal tension distribution. Releasing excessive stress from spokes we get long-lasting and high performance on every wheel. Tire Width Recommendation: - For maximum aerodynamic efficiency on your wheels we recommend that the width of the tire does not exceed the outer width of the rim. Our AIR + PLUS rims are very wide with 27 to 30mm, opening the tire enough so that the tire and rim walls form a seamless line. - Clincher or tubular tires from 23mm up to 28mm are perfectly integrated into our AIR + PLUS rims.
