Overview

Why Do Cyclists Need a Presta to Schrader Adapter?

The MSW Presta Valve to Schrader Valve Adapter is the small, easy-to-lose piece of kit that solves a genuinely annoying problem: being stuck with a Presta-valve road or gravel bike when the only inflation source around is a Schrader-compatible pump or gas station air compressor. This brass threaded adapter threads directly onto a Presta valve stem, instantly converting it for use with any Schrader-compatible inflation device. It is small enough to tuck in a coin pocket or zip it into your seat bag and forget it is there until you need it.

Compatible with all standard Presta valve sizes found on road, gravel, and mountain bike inner tubes and tubeless valve stems. The machined brass construction provides a secure, airtight connection that does not leak under inflation pressure. Keep one in your kit bag, one in your car, and one at the shop. At this price, buying a few extras is a no-brainer.

Can I use this at a gas station air pump?

Yes. Thread the adapter onto your Presta valve stem and it will work with virtually any Schrader-compatible inflation source, including gas station air pumps, car pumps, and most floor pumps with Schrader heads.

Does the adapter work with tubeless valve stems?

Yes, as long as the tubeless stem has a standard Presta thread. The adapter threads on just like it would on a standard inner tube Presta valve.

Will this adapter leak during inflation?

The machined brass construction provides an airtight seal when threaded on securely. Make sure to snug it down by hand before connecting your inflation device for a leak-free result.
