Spare tube for Sduro Trekking 5.0

[kiltym]

Sorry for the ignorant question, as we are new to owning and having to fix bikes .

Got our first flat today, which we will repair, not a big deal.

But I think I would like to get a spare tube to carry as it is much each then trying to repair while in the middle of a long trip.

The tube states the following "Schwalbe" "No. 17" and 28". There are some additional numbers, but they were not printed well and in turn I cannot read them.

The presta valve is 30mm long, yet I only find 40mm+ when I look. Maybe I am measuring wrong...

So, my question is what do I order. When I look at Schwalbe 28" SV17 tubes, there are more numbers and choices then I understand.

widths, etc.

Is this what I need: https://www.amazon.com/Schwalbe-Bicycle-Presta-Valve-37-622/dp/B004Y6H0JK

Appreciate the advice as I realize this is a pretty basic question, but without the full part # legible I am a bit at a loss.

Also, what is difference between 28" and 700c? Are they the same, or not? Sure is a Euro/America thing.....

I always order my spare tubes directly from Schwalbe's website. They have good tubes so even if you don't have Schwalbe tires they are a good choice. If you put in your tire size at their website they should tell you what your tube choices are. I think they may require you order a pair however. Usually the tubes fit multiple tire widths. Schwalbe's site will also explain the various tire markings. 28" and 700c are the same. For best accuracy, look for the ETRTO size on the tire. For your bike, I found 42-622 on the Internet (if you have the stock Michelin tires). Go to Schwalbe's website as they explain all this:

Thanks for the replies. The tire has 700-40C on the side, and 42-622.

Based on that, I bought this tube (Continental), as it was much cheaper then ordering from Schwalbe.com. Seems to be fine quality based on reviews I found, but I guess time will tell once I use it: https://www.ebay.com/itm/New-2018-Continental-Tour-28-700c-28c-Presta-Valve-Touring-Bike-Tube/282786382257?ssPageName=STRK:MEBIDX:IT&_trksid=p2060353.m1438.l2649

That will work fine. I recommend you put the spare tube in a ziploc bag along with some talcum/baby powder. The talc makes installing the tube easier. Of course you will also need tire levers and a mini pump or CO2 inflator for emergency repairs. Not a bad idea to also have a patch kit and a tire boot as well.

Thanks, have all that, except the talcum powder trick! Thanks for the tip.
