Inner Tube Set

A flat tire should not end the build.

The Projekt46 Inner Tube Set is a straightforward replacement or garage spare for riders who actually use their bikes. Heavy-duty butyl rubber and TR4 straight valve stems provide dependable air retention for street and trail use.

Why It Matters

Keeping the correct front and rear tubes on hand saves downtime and prevents a simple puncture from becoming a missed riding day.

What’s Included

• One front inner tube
• One rear inner tube

Fitment

Choose the 12"/14" or 14"/17" set to match your wheel and tire sizes. Confirm the tire-sidewall size, valve type, and rim opening before ordering.

Before You Order

Install without pinching the tube, seat the tire evenly, and inflate only to the tire manufacturer’s specification. Inspect the tire and rim for the original cause of the puncture before riding.
