Paradox77

Hey folks,

I went to my local stores and they don't seem to carry inner tubes that will fit my tires. So I guess I have to try and find it online however I am not sure which one actually fits? My tires are the Schwalbe Pro One 30-584. My current inner tube says Schwalbe No 12G Extralight 28/44-584/590 but I can't seem to find it anywhere.

New this this inner tube stuff (new to cycling) so forgive my ignorance.

Does anyone have any advice or recommendations?

Inner tube sizes are usually given as a range of widths for one particular BSD (bead seat diameter). In the case of your inner tube it appears that they are giving the width range 28mm to 44 mm for both 584 mm and 590 mm BSD tires.

Different tube brands will display the info more understandably than others.

If you went to a bike shop, did you not ask them what they had that would fit? If you went to a discount store with not any knowledgeable help, then what brand of tubes were you looking at? Maybe we can figure out what size range they make for your particular 30x584 tire.

Paradox77

They said they only had something a little bigger which is for mountain bikes that might squeeze in so I didn't want to risk that. I believe the PSI level is quite different between a road bike and a mountain bike.

As far as which brand of tubes, I don't have any preference, just what fits. Butyl tubes are fine for me. Thanks for chiming in.

Have you looked at any of the big box discount stores? Walmart, Target, Academy Sports or Dick's Sporting goods? (assuming you are in the USA).

Look for 26" tubes. Bell makes some in a 26" size for 1-1/4 to 1-3/8" tires. Your 30mm wide tires are only 1.75 mm smaller in width than a tube that specifies for 1-1/4" (31.75mm) widths. So maybe it won't be too big.

https://www.walmart.com/ip/Bell-Stan...1-375/17619563 Though this is only for Schrader valves. What is yours? Why it say 3 speed only I've know idea. I don't know why a tube cares how many speeds I have.

However if you aren't in a hurry for something right now, then just order them. But even on the Schwalbe site, I'm not finding those tires or tube size you state as being currently made. 20 - 44 is a pretty big width range to me.

This is the closest Schwalbe tube on their site I could quickly find.

Maybe some other members will have some better advice or know of where to get a more perfect size.

If your tires are 700x30, just get a tube like this:

https://www.amazon.com/Continental-7...91774867&psc=1

They fit 25-32. Anything that even fits up to 28 will work for 30s. I'd not go way past your stated tire size since you will more easily pinch them when installing.

I got a 5-pack of the Conti race tubes on Amazon for cheap. They work well and I also ride the Schwalbe Pros.

Canyon roadlight no? for some reason it seems Canyon has access to some schwalbe tubes nobody else has. My Canyon came with xtralight schwalbe tubes that are not listed anywhere.

Paradox77 just pony up for the exact fitment in a quality brand TPU and take all the advantages which come with it:

Paradox77

Yeah exact problem I have. I contacted Schwalbe and they say for me to contact Canyon....so annoying...

Paradox77

Damn that's expensive!! But thanks for linking it!

Wouldn't this stretch enough to fit a 30mm tire?

I think the OP hasn't said whether the bike is a Canyon or what. Someone suggested that it is earlier in the thread, though, and wasn't contradicted, so I did a quick search:

"To address this issue, Canyon introduced a radical new design for its 2XS and 3XS women's bike models. Instead of building the bikes around the typical 700C (622mm) wheels, the two smallest sizes use a new 650B (584mm) road wheel standard. This keeps the geometry and ride qualities in line with the larger sizes."

So it looks like the bike in question takes 650b (584-mm) tires (also known as 27.5" tires). (All those numbers correspond to the effective diameter of the rim.)

So the OP should search for 650b (or 27.5") tubes whose nominal width includes the width marked on the bike's tires. If the tube is marked as being usable with, e.g., tires marked anywhere from 28 mm to 44 mm, as listed in the opening post, then that tube should work fine. The closer to the width marked on the tire, the better, but a slightly smaller or even slightly larger tube will work.

Paradox77

Yes it is indeed Canyon. More specifically Endurace AL 2XS. All these numbers are totally confusing for me sorry. So what someone above mentioned this https://www.schwalbetires.com/SCHWAL...2B-26-10423223 should fit? Thanks for your input and insight!

Trakhak

Tell us what numbers are printed on the tire label. We can then tell you which tube(s) will fit best.

Sy Reene

He did in the first post. 30-584

Trakhak

Thanks. I fixated on the tube numbers in the opening post. So the tube needed is likely listed as 650b x whatever range includes 30-mm width.

Just did some searches; couldn't find any such tubes. All I can suggest for the OP is to ask a local bike shop to look through some distributor websites for the tubes. The Quality Bicycle Products website is where I'd start.

With butyl rubber tubes they'll expand to fill up the extra space. However the more they have to expand, the more they'll behave like a balloon if you do get a puncture. The less the tube has to stretch, the better. Then a puncture will be a slow leak instead of a rapid leak. I've sometimes just topped off my tire after flatting and rode the bike home to fix the flat. Maybe stopping once or twice to top off the tire with air or CO2.

Tubes that are too big might wrinkle or kink. If badly wrinkled there will be places where the tire won't be evenly supported by air pressure and you might feel that as a bump. Also the folds will rub on each other every time the wheel turns and wear a bad spot that will eventually be a leak.

Paradox77

Great insights and information. After an exhaustive journey of searching, I think I will try this one https://www.schwalbetires.com/SCHWAL...2B-26-10423223. It seems the most compatible. It might have to stretch a bit to fit 30mm but better than kinking like you said going with larger.

Iride01 

Paradox77 Thanks for the props. Just realize it's all conjecture on my part based on years of observation which is just circumstantial and anecdotal at best. <grin>

So YMMV.

If it does, let me/us know.

Did you not notice that the Pirelli I linked to is the *exact* fitment you need?

Since you’re likely unaware, let me make clear that the Pirelli TPU tube will provide better puncture resistance than butyl (particularly compared to an undersized, overstretched butyl tube), lower weight, lower rolling resistance, and enhanced safety (TPU does not tear and is less likely to suffer sudden deflation). The properly sized TPU will probably offer better pressure holding than an overstretched (and ergo thin) butyl tube.

While the Pirelli tubes are expensive, I did want to point out the benefits which come with TPU.

and they are patchable contrary to what some people think. I have patched my aerothan's 2X with park glueless with no issues. I think the secret is to carry some alcohol wipes and clean the surface.

terrymorse 

Do you rough up the surface of the TPU tube before applying the patch?

The instructions from RideNow include that step, but it hasn't seemed necessary (so far).

jadmt

no just clean it with alcohol and don't touch the surface to be patched with your fingers. also make sure you don't touch the stick part of the patch with your fingers. Schwalbe says to skip roughing up step in their kit. I have both the park and the schwalbe glueless and have used one of each and both have not leaked.

chaadster

Yeah, I’ve also successfully patched both Aerothan and RideNow TPUs with glueless patches from Lezyne and Park, using only isopropyl alcohol to wipe down around puncture.

Paradox77

I did and I responded up top. Since I am a total beginner, I am not sure if I should risk using such expensive tube. I believe putting it on wrong (like with tire lever), I could easily pinch flat it because of lack of experience and there goes $30+. But thanks for pointing out all those benefits. I had no idea TPU is more durable than tubyl tubes. I actually thought it was the opposite seeing the "thickness" of the tubes.
