The 45 Foundation is a modern carbon road wheel in every way. Riders with inclinations toward racing and hard solo efforts or those looking for the road lost and forgotten will find the dynamic properties the modern road rider needs. Built upon over a decade of carbon wheel crafting experience, the 45 brings Enve’s knowledge and technology to the masses. Blended aero properties, tubeless compatibility, and pinch flat protection for the rider looking to test the waters on carbon wheel performance.

• Full carbon rim is optimized to further improve tubeless tire and rim reliability with a hookless bead design that allows for the precise rim dimensions required to achieve the best tubeless performance
• Wide hookless bead deign greatly reduces the likelihood of pinch-flatting by providing a blunt surface upon which to bottom out the tire, dissipating energy across a larger surface area and preventing tire damage
• Innerdrive mechanism features oversized 42mm steel ratchets positioned inboard and over the bearings, reducing stress on the axle and bearings while ensuring positive and reliable engagement
• Interchangeable ratchets (sold separately) allow riders to easily tune their rides for their personal performance needs. Whether it be maximizing efficiency, response, or reliability
• Molded Spoke Hole Technology offers a variety of benefits that ultimately result in a more durable and reliable carbon fiber rim and wheel
• 45mm depth and 21mm internal rim width, Aero Optimized design to support 25 – 28mm tires. For use with Tubeless tires only
