Compatibility Notes

Designed for 27.5 inch / 650B wheels only.
Best suited to tyres marked 27.5 x 1.95 to 27.5 x 2.125 or 50-57-584.
The rim must be suitable for an AV / Schrader valve.
Not suitable for Presta-only rims unless the rim has been safely adapted.
Always check tyre sidewall size, rim tape condition and valve compatibility before installation.

Durable Butyl-Style Rubber Construction

This tube uses practical butyl-style rubber, the most common material for reliable bicycle inner tubes. Butyl is popular because it holds air well, installs easily and offers dependable performance for everyday MTB, commuter and recreational riding.

27.5 / 650B Wheel Compatibility

The 27.5 / 650B size is widely used on mountain bikes, hybrid bikes, e-bikes and some comfort-focused commuter bikes. This tube suits common mid-width tyres used for trail riding, urban paths, gravel paths and mixed-surface riding.

50-57-584 ETRTO Fit Range

The ETRTO size range gives a more precise fit reference than inch sizing. A 50-57mm width range suits tyres around 1.95 to 2.125 inches wide, making this a useful tube for many 27.5 inch bikes.

AV / Schrader Valve Convenience

The AV valve, also known as Schrader or Auto valve, is easy to use with many floor pumps, hand pumps and service station inflators. This makes it especially convenient for commuters, families and casual riders.

48mm Valve Length

The 48mm valve provides practical pump access on many standard MTB and hybrid rims. It gives more usable length than shorter valves while still keeping the wheel setup neat.

Everyday Service Reliability

A fresh tube is often the quickest and most reliable fix for a puncture, slow leak or valve failure. It is a sensible spare to keep at home, in the car, in a ride pack or in a workshop service kit.
