Tube help

Hi ,
Love riding my bike out know very little about maintenance, part specification etc .
I have a carerra crossfire and my inner tube has recently burst usually I’d leave it in to the shop and they’d tell me what I need but can’t at the moment .i want to order a new one online but do t know what size it is.the inside tube says schwable no.19 28/29/27.5” and the outer tyre says 44-622 (700x42c-28x1 and 5/8s. also my valve is ”presto” . can someone please tell me what size my tube is and any recommendations of any good is websites is much appreciated!

Not use this brand so have no idea about quality
700cc is the wheel diameter and the 42 is the width of the tyre these are the most commonly used measurements the other numbers are just a different way of measuring the same thing

I see thanks for your help! I ordered 2 just now if you have any other suggestions of website or brands e.g continental it would be much appreciated

For example would this work?

 

[13 rider]

No that's for a tyre width 18mm to 25mm you want one were 42mm is within the range

 

[Dec123]

And what is deemed within the range sorry I’m new to this

 

[13 rider]

No problems tubes are made to fit a range of tyre widths the one you posted smallest 18mm biggest 25mm as yours is a 42mm it not in the range .the one I post was smallest 35mm to 43mm so your tyre would be in that range

Ah I see . So the 2 measurements I should be looking for is 35mm-43 (range) and also 28”?

28" An old fashioned way of saying 700cc just to confuse you
Didn't have to be exactly 35_43 as long as 42 is within any given range

Perfect and they’re the only 2 specificitions I should be worried about ?

Yes the 700cc /42 mm numbers are the mostly commonly used now so ignore all the other numbers

Hope everything goes ok . It's worth ordered a spare you wouldn't be the first person to trap the tube will refitting the tyre causing a puncture
