What Makes the Problem Solvers Valve Extender Worth It?

The Problem Solvers Presta Valve Extender for Removable Cores is the clean, reliable solution for running deep-section rims with standard-length valves. Unlike basic extenders that thread onto an intact valve, this design requires a removable valve core, letting you spin off the core, thread on the extender, and reinstall the core through the extender for a secure, airtight connection. The removable-core design eliminates air loss at the joint and plays nicely with both tubeless setups and standard tubes.

At 70mm, this extender reaches through the deepest carbon hoops without issue, and the black anodized finish keeps things looking intentional rather than afterthought. Compatible with any Presta valve that features a removable core. A must-have for climbers, time trialists, and anyone chasing deep-dish aero gains without the headache of sourcing long-valve tubes.
