Our size guide will be able to give you the best advice in getting the right size tube for your bike

There are three main valve tyres, Presta, Schrader and Woods. To make sure you have the correct type for your requirements please see our valve type guide and also double check the product listing to confirm your selection

Yes. Don't worry, we're here to help, simply see our Returns page for full details. Regardless if you have made a mistake, we're here to help get you sorted!

We wouldn't get very far over the years if we sent damaged items, lord knows where we'd even source pre-damaged inner tubes! However, there is usually a simple solution, make sure to read our Fitting Instructions page and this will answer this one before it happens!

Wo Wo Wo! Easy! Please see our 'Read Me' in the 'Puncture Protection' drop down menu, this will help!

You'll see that valve come in a variety of sizes, one solution is to measure your current valve or check out our valve guide to make sure you have the right valve for the job

Yes, you're correct! With quality tubes you have a stronger rubber so that will help, also their manufacture quality means less issues with breakages and also they don't loose pressure as easily as standard tubes, meaning more consistency and improved performance. Remember the adage, 'buy cheap, buy twice'.

We're constantly expanding our ranges to help as many riders as possible and if you can't find what you're looking for, please get in touch, we'd love to hear from you and hopefully we can get what you need (or we may already have it!)

Any valve cap is better than no valve cap, they keep the dust out of you valve and protected the internals. To go one step further a metal valve cap has the same benefits, increases pressure retention (incase of a leaking valve core) and look a dam sight better in our opinion if you like that sort of thing. So yes, they are well worth using.
