Overview
Why Do Aero Rim Riders Choose EVO Presta Valve Extensions?
The EVO Presta Valve Extensions solve a problem every deep-rim rider has hit: Presta valves too short to reach through a deep aero section, making inflation slow and frustrating mid-ride. The CNC-machined 7075 alloy construction gives these extensions the rigidity and dimensional accuracy needed to thread on cleanly and stay put under pressure. At 70mm, they add enough stem length to work comfortably with most mid-to-deep aero rims, and the sealed base design prevents high-pressure air loss at the connection point, a genuine engineering detail rather than a spec-sheet line item.
Sold as a pair in black, these extensions pair cleanly with aero dish rims on road and triathlon setups where a short valve would otherwise be unworkable. The precision alloy threading engages the existing valve core without slop or cross-threading, and the anodized finish holds up through repeated use and regular cleaning. If you're running 50mm or deeper carbon rims and tired of fighting a pump head at the valve, this is the fix. Compatible with standard Presta valves.

FAQ
Good questions
Get to know EVO
There's more to EVO than this one product. Our EVO page has the full EVO lineup we carry and more about the brand.
Visit the EVO page →What rim depth do these extensions work with?
The 70mm length works well with most mid-to-deep aero rims. For very deep rims over 60mm, measure your valve and rim depth together to confirm clearance before purchasing.
Do these work with tubeless valves?
These extensions are designed for standard Presta tube valves. For tubeless setups, longer tubeless valves are typically the better solution.
Will these leak at high pressure?
The sealed base is engineered to prevent high-pressure air loss at the connection point. Thread them on snugly and they hold reliably at road and TT pressures.
