Great product provides alternative to tubeless.
These lightweight tubes provide a great alternative to the hassles of running tubeless tires for summer. Good product, good price and delivered quickly.

Both the store and the Surly Fat bike tube gets a Thumbs up!
The Surly Fat Bike Ultra Light tube is a tad lighter than the standard Surly Fat bike tube and it fit and rides well. It replaced a standard tube that got a puncture. All good including the store.
