Gaadi Inner tube.

[Saracenlad]

Can anyone help me to decipher the markings on my tyre so that I can buy the correct size Gaadi Inner Tube?
My tyre says :- 650B 27.5 x 2.3 (58-584).
I only understand 700 x 32.
Yes, I am a Luddite.

Do you have to have a Gaadi inner tube?
I always buy the brand Schwalbe.
Do a Google search for Schwalbe SV21 and Schwalbe AV21. One has a Presta valve and the other one has a Schrader valve so you could choose either as they are both the same size but different valves. Hope this is of some use to you.

Thanks for the reply. The Gaadi is a 2 ended inner tube and the ends Butt Up. I want it as a get me home rescue if I get a puncture. I just cannot understand the numbers on my specialized tyres. The thought of getting a puncture my Electric Assist Specialized scares me.

The Gaadi tube is the funny double ended thing. So I assume the OP wants to enjoy it's alleged benefits.

Yes. The funny double ended thing could be a life saver.

I await your report with interest. It would make life with an E-Bike much easier. But I keep ignoring the p word.

“The thought of getting a puncture my Electric Assist Specialized scares me.”

Going off on a tangent, I had been toying with the idea of “Breakdown cover / Cycle Rescue Insurance” for quite a while. Then one day last October I got a puncture and I had no repair kit with me.
That incident made up my mind and I signed up to ETA Insurance, Cycle Rescue Insurance which costs £24 for twelve months. I have not had need of their services so I cannot say if they are any good or not.

The key in your search will be adding 584 which is diameter in mm

buy the correct size Gaadi Inner Tube?
My tyre says :- 650B 27.5 x 2.3 (58-584).

Because these are double ended the extra (622-584mm) will not be an issue and this is rated up to 2.1 inches, so 2.3 at a stretch.

Let's take 650B 27.5 x 2.3 (58-584) to bits.

650B is a nominal wheel size. It's a stupid coded way of saying that you have a 584mm rim. Like 700C is annoying code for 622mm. Ignore it.

27.5 x 2.3 is a size in inches. The 27.5 is just annoying. It's the total diameter of wheel plus tyre. Who cares about that? Like the 650 in 650B. Ignore it. The 2.3 is the tyre size in inches. This is the first bit of info that's actually useful. This happens to be 58mm.

58-584 hooray! this actually means something. It means you have a 584mm rim and a 58mm tyre.

So I did a bit of googling auto translating and got to here https://shop.gaadi.de/GAADI-Comfort-16-29-Fahrradschlauch-AV-Schrader-37-57mm

It says (in German) The GAADI Comfort bicycle inner tube is suitable for permanent use and one tube covers wheel sizes from 16 to 29". That's impressive, I didn't know that.

So, as that is sized 37-57mm and you have a 58mm tyre, that's 1mm too small. But the next one up is 60-74, which is 2mm too big.

https://shop.gaadi.de/GAADI-Comfort-16-29-Fahrradschlauch-AV-Schrader-60-74mm

I think you could get either. The bigger one errs on the side of caution I suppose.

Provided you want a schrader valve, that is.

You could have just used the drop down on the website to pick their English language one .

Thank you so much for all of that. I should be okay to buy one now. Love this forum!!
