Description

A small alloy adapter that lets you mount a Presta-valve tube in a rim drilled for Schrader. Set of 4. Solves a common, annoying problem in 30 seconds.

Why it works

Closes the gap a Schrader-drilled rim leaves around a Presta valve. Schrader valve holes are 8.5 mm. Presta valves are 6.5 mm. Without an adapter, the valve rattles, leaks at the rim, and over time chafes through.

Lets you run TPU on a Schrader rim. Most TPU tubes (including all Eclipse TPU tubes) are Presta only. This adapter is what makes them fit a Schrader-drilled rim.

Sold in fours. Two wheels per bike, two bikes per garage. Or one set lasts a long time.

Best for

  • Older or budget rims drilled for Schrader where you want to run a Presta tube
  • TPU upgrades on bikes that originally came with butyl Schrader tubes
  • Backup parts for the box you keep in the garage

What makes Eclipse different

Eclipse pioneered TPU inner tubes in 2011 — and we build the small stuff that goes with them to the same standard. Every part is selected and tested to work cleanly with TPU and with the patented all-aluminum Eclipse valve.

All Eclipse TPU tubes are

  • Manufactured in Germany
  • individually water-tested and 24h pressure-tested
  • 100% recyclable

What is TPU?

  • TPU is known for its high elasticity, flexibility, durability, and resistance to abrasion, which makes it first choice in multiple sports applications, like bicycle grips and inner tubes. Eclipse TPU material can be stretched by over 400% before failure.

  • Modern TPU is a highly sustainable material which can be recycled and reused without losing significantly on its material properties, it's therefore poised to lead in future material developments
