keep rolling

These tubes appear to be very well made. I've not actually needed to use them yet. But I purchased them as a friend uses them a swears by them. He's not one to do that if a product is not of good quality and doesn't do what it claims to do. They are a bit expensive but if they keep you rolling it's a price worth paying.

Great tubes

Have had no issues with these tubes. The added weight is minimal for the reassurance of not having to spend the time repairing flats.

Why wouldnt you

Easy additional line of defence. Never a good time but especially at this time of year not the time to be roadside swapping tubes. Not infallible but will deal with most. Negligible compromise in weight for an invaluable provision.

Slime Tubes

In my first 60 miles on standard tubes I got a puncture. Put these on nearly 400 miles later no punctures. Admirably I haven't been on such "rough terrain" but still.Would recommend though maybe not if you're really into getting everything out of your bike as I think they do slow it down slightly rotation mass.Very helpful not having to change repair inner tubes the whole time!

Great

Been using these for a couple of years now and I've had no flat tires at all on my 5 day work commute I'm sure these have stopped many flats from happening. Its the only inner tube I'll use now.

Tyres Guide

What type of tyre do I need? 

It’s best to choose a bike tyre based on the type of riding you’re going to be doing.  

Road bike tyres 

Road bike tyres are identified by a smooth tread pattern and narrow width for speed and efficiency.  

Mountain bike tyres 

MTB tyres are much wider with chunky tread for added grip on off-road conditions.  

Hybrid/ commuter tyres 

These tyres will often blend characteristics from road and MTB tyres with added puncture protection for daily durability.  

Does tyre width matter?  

Thin tyres are fastest as they have low rolling resistance and are more aerodynamically profiled.  

Wide tyres are more comfortable and stable due to the increased contact patch with the ground.  

How to check your current tyre size? 

Take a look at the sidewall of your current tyres and you’ll see one or two sets of figures;

One is the traditional size like 700x28c or 27.5x2.2.  

The first figure is the tyre diameter (size). The second is tyre width. Note: road bike sizes are in mm, MTB sizes are in inches

The other set of figures you may see is ETRTO sizing like this 28-622.

The first number here is tyre width while the second number relates to wheel diameter.

Here is a comparrison chart for traditional and ETRTO sizing to help you choose the correct tyre size.

 18-622  700 x 18C
 23-622  700 x 23C
 25-622  700 x 25C
 28-622  700 x 28C
 32-622  700 x 32C
 37-622  700 x 35C
 47-622  700 x 47C

 54-559  26 x 2.1
 55-559  26 x 2.2
 58-559  26 x 2.35
  27.5" (650b) mountain bike wheels
 50-584  27.5 x 1.95
 54-584  27.5 x 2.1
 57-584  27.5 x 2.25
 29" mountain bike wheels  
 50-622  29 x 2.0
 54-622  29 x 2.1
 55-622  29 x 2.2

Will this tyre fit my wheel?   

Your new tyre must be the same diameter as your current one (to fit your wheel rim).  

Then, you need a choose a tyre which will fit your frame.  

Road bike tyres are generally 21 – 28mm wide 

MTB tyres can range from 1.5”-5” 

To make things complicated road tyres are measured in mm, while MTB tyres are in inches.  

How wide is too wide  

You want to leave at least 4mm clearance between your frame and tyres to prevent rub and allow for mud clearance. 

Measure the following areas on your frame: 

Fork crown (top) 

Brake calipers (make sure you squeeze them) 

Chainstays 

Seatstays 

Subtract 4mm and you’ll have the maximum width your frame can handle.  

What is the best type of tyre for daily riding? 

If you’re commuting, riding and training daily you’ll want a tyre with some form of puncture resistance. 

Puncture resistance often comes in the form of a harder or thicker rubber compound, or a protective layer running underneath the tread pattern.  

What are tubeless tyres 

Tubeless tyres do not have an inner tube. The tyre and rim of your wheel (you need a tubeless ready rim) create an airtight seal with the valve directly mounted on the rim. 

You can run these tyres at lower pressures for an improved ride quality. A bigger contact with the ground means you have improved traction when cornering. 

Tubeless tyres often come with liquid sealant that creates a seal that may heal itself on a small puncture so you can keep riding home.
