ProsPromptness of delivery
I ordered new tyres for my wife's bike over the Easter weekend . They arrived on the Thursday and by Friday they were fitted ready to go, with plenty of grip compared with the old ones i took off. Thank you for your prompt service and updating me with delivery times.

I am looking at these tyres for my Tern Link B7 folding bike which I mainly use off road on gravel paths. Is this a suitable tyre? I am a cycling newbie so learning as I go! I have been told the tyre size I need is 20" 1.5"
Are these the best or is there something else you could recommend?
Hello, as we require more information to help us with this matter please send us an email to [email protected] and let us know the ETRTO code on the tyre sidewall, this is a two-digit followed by a three-digit number which helps us confirm tyre compatibility.


I currently have 20

These will probably be fine, you may need slimmer inner tubes.

Can I use this with a wheel diameter rim to rim = 16 Inches

Schwabel Marathon 365 (20 x 1.5 inches 406 Why are Tyre sizes so varied by description. Time for some standardisation me thinks.
I see you have one Klickfix Item. I am looking for a 43mm extension for a handle bar mount???
Hi there,

There are many tyre sizes available, so the easiest way is to use the bead seat diameter, in the case of this tyre that is 406mm. We would need to know what the previous tyre is ideally.
