2022 Vado Inner Tube size

[Decho]

I find tyre and tube sizes a bit confusing. My 2022 Vado 4 has 650b rims with pathfinder sport reflect 650bx2.3 tyres. I believe these are 27.5 size wheels? My 2020 Vado had 700c rims….29inch?
The 2022 Vado also uses the Schrader valve rather than the presta.
i like to carry a spare tube but not sure what size is correct…I bought the same size as my 2020 Vado but with a schrader valve but I now think this is the wrong size. Any idea what size I should use? Ive looked on the Specialized site but can’t find the info.

650b (French) = 27.5" (Inch) = 584 mm (ETRTO). Your 2.3" tyre (58 mm width) is identified as 58-584 by ETRTO (the latter is the only comprehensive and consistent system).

The matters are confusing with the ETRTO 622 mm wheels, because a 622 mm wheel is always 700c but:

• It is 28" for the tyre width less than 2"
• It is 29" for the tyre width of 2" and up (fat tyre wheels are bigger, aye?)

The ETRTO system leaves no doubt. The first figure such as 57 is the tyre width in mm, the second is the inner tyre diameter (rim size) such as 622: 57-622 and you know everything (it is a 700c, 29x2.25" tyre).

The inner tube must match the rim size, and is sold for a range of tyre width, for instance: (622 mm, 700 c, 28") wheel, 28-38 mm tyre width".

Presta (FV) or Schrader (Auto) valve has to match, too.

Thanks Stefan Mikes for that, I understand now….I think
it seems strange though they went from 29inch rims to 27.5 And also Schrader valves, which often seem to be fitted to cheap bikes(which the Vado most certainly isn’t!)
I haven’t as yet had a chance to do long range rides on my new bike because I’m going through Radiotherapy for Prostate Cancer at the moment, but am looking forward to seeing how it compares with my 2020, which was a fabulous machine…I only changed it because I wanted the bigger battery. I’m keeping my old one for now just in case!

Going for the 27.5" seems to be an intentional action to bring the Vado more into the SUV e-bike territory. It allows using wider, comfortable tyres. I'm surprised with the Schrader valve, too. At least it is easy to use a compressor at any service station!

I sympathise with you! Go on and fight the beast!

Thanks Stefan Mikes, indeed I am fighting like hell and full of energy and positivity!
I am determined not to let this cancer define me.

Yes, perhaps. On your recommendation I fitted Smart Sam Plus tyres to my 2020 and they are very good. Maybe I should look at putting these on my 2022? What Would be the widest tyres I could fit on my 2022 model? Maybe this has been discussed already, I will take a look.

@Decho: If Specialized said it should be 27.5x2.3", please keep to that size. It is optimal for your wheel rims, and with agreement with the TCD-w2 display. Also, the mudguards are the limiting factor. I do not know what is wrong with your stock tyres? Smart Sams are good but they increase rolling resistance a bit, making you unnecessarily slower (or using more watts from your battery!)

 

[Decho]

I would like to take my bike a bit more off-road, nothing too serious but forest trails which can be a bit rough in places here in Scotland. I’m wondering whether the stock tyres are robust enough for this?

Decho, I ride my big Vado in forests on Specialized Electrak 2.0 (29x2") tyres -- the Type Approved model for Speed Vado 6.0 -- which are slick, only these are made of soft, grippy but fast rolling rubber. I regularly ride in forests of my wide neighbourhood and guess what? They even cut through shallow sand!

The only crash I had on these tyres occurred when I was riding at pretty high speed through the forest, and the rear wheel slipped in a small muddy puddle (also because of the excessive power to the rear wheel!) Necessary to mention I used to experience crashes in the same big forest on Smart Sams.

I think people (including me) try to replace something good with something "even better". Not sure what surfaces you're finding in Scotland but I'd say try the stock tyres, ride carefully, and find out for yourself!

 

[Decho]

I will do Stefan Mikes!

Decho, a funny thing from the Saturday's ride:
Our mate was leading the small group over a "detour" he invented (to spoil my own route!) Damn him! He lead us into mud and deep ruts offroad. To avoid the "road", brother and I tried to ride a meadow along, which turned out to be a... marsh Thanks to my 2" tyres, I could survive (brother had 2.6" tyres, even better!) I needed no Smart Sams to ride there!

 

[Decho]

I am not very knowledge about tyres but I think what I was concerned about was how tough the stock tyres were compare to something like Smart Sams. Would they be more likely to serious damage? Also having bought my lovely mountain bike out in Fuetreventura which have wider tyres at a lower pressure I realise how much more comfortable the ride is when on rough tracks….and there are plenty out there!

Decho: You won't learn if you do not try. Now, it is a waste not only of money but also good rubber to replace tyres on a whim

Even if your Vado allowed wider tyres (which I doubt: the mudguards!), the rims are the limiting factor, too. Put too wide tyres on specific rims and the tyre will assume wrong profile, which is bad.

I see a variety of questions, addressing in order:

1. 650b rim size is interchangeable with 27.5 - if there is any actual difference, I don't know what it is.
2. tubes come in a size range - choose one which covers your tire size. I bought a "27.5 x 2.1-2.35" for my Vado 4.0 with 650b x 2.3" tires.
3. match valve type - schraeder or presta - to the rim. IMHO each has its advantages, but for this bike it doesn't matter
4. best wishes on the cancer treatment
5. stock tires seem just fine on my 2022 Vado 4.0 - maybe don't change tires until/unless you find the stock ones don't work for your own situation?

I like to buy a tube that does not go over the tire size so its easier to install.
