Schwalbe 2 x 28" / 700c Inner Tubes 700x32c With Presta Valves

Product Information

Using our 700x32c measurement as an example, the first number is for the outside diameter of the wheel, including tread. The second number is the width of the wheel. Both of these numbers can vary depending on manufacturing issues, tire pressure, and even the tread itself. The tyres can differ, but the 28”, 700C and 29er are all the exact same rim diameter. The 700 markings will be followed by the width in mm, and the 28 or 29 markings will be followed by the width in inches. What does 700x35c mean? From our perspective, the reason doesn’t really matter. What actually matters is that tires that are ‘just about the right size’ will often not be close enough at all and will give you problems and opportunities-to-learn in the near future. The modern standard for road, cyclocross, and many hybrid tires is 700C. You’ll also find 700C tires on some European-style cruiser bikes. The “700” refers to the rough outer diameter of the tire, although the actual outer diameter will vary greatly, depending on the type of tire and tread pattern.

The flexibility of the inner tube material makes a difference too. Inner tubes are made from either synthetic butyl rubber or natural latex rubber. Latex is more flexible and thinner too, so if you want to reduce rolling resistance then latex is the way to go. According to Jarno Bierman at bicyclerollingresistance.com, you’ll save 4-5 Watts using latex inner tubes over butyl tubes. That’s probably not a difference you can feel, but it’s one you can measure with a stopwatch.

If you crouch down by the side of one of your bike wheels and take a look at the sidewall you’ll be able to get all the information you need – simple as that. READ THIS NEXT What Size Bicycle Tire Tube Do I Need? (Fast Answer) Do you also need a bike tire to go along with your tube?

The biggest factor will be whether or not your bike has room for the tires. If you’re going for a slightly narrower tire (but maintaining the diameter), you should be fine. Putting wider tires on can be more difficult, though, so it really depends on the bike’s geometry. tires are approximately 700mm in diameter and 32mm in width. Translated to inches, you’re looking at roughly 27 ½ inches by 1 ¼ inch. However, these are considered nominal measurements, meaning they’re a close estimate rather than an exact number. In addition to knowing the correct tube size and width for your bike, you’ll want to make sure you choose the correct valve stem (the part that goes through the rim and allows you to fill your tires). Shrader valves are the most common type on the market.

The simple rule here is to choose a new tire that says it is “700x38c”. It’s no more complicated than that. Even less complicated than choosing a tube! This is a common way for bike tube sizing to be listed. If you see a tube designation written this way, it means it can be used in any tires within 35mm-43mm wide. The 700 refers to the diameter of the wheel, so that number is firm depending on your rims.

Just as a 700C wheel is the same diameter as a 29” (29er) wheel, 650B shares the exact same rim diameter as 27.5”. 27.5”/650B rims have a bead seat diameter of 584mm, and 29”/700C rims have a bead seat diameter of 622mm. Latex inner tubes have been claimed to be more puncture-resistant, because the rubber is inherently stretchier. Whether that makes a difference on the road is debatable as a tube held in place by a tyre may not be able t stretch as much as a tube being pressed against a broken bottle in an advert. For everyday riding you probably don’t want fewer punctures to come at the expense of daily inflation anyway.A wrinkle to all of this is that thinner and lighter butyl inner tubes have become available in the last few years. Bierman tested a 100g butyl tube against an 80g latex tube, but you can get butyl tubes as light as 50g. Because they’re thinner, they have lower rolling resistance but won’t lose air like latex, but their increased fragility means they need more care in handling and puncture more easily.

Instead of measuring the outer edge of the tire’s diameter, this method measures the tire’s bead, which is the surface that attaches to the rim. This helps to reduce confusion and limit ambiguity about whether or not a tire will fit a certain rim. Of course, it is still a nominal approximation and subject to varying tire pressures and rim widths ( Source). Tire Size Chart

Tyre maker Challenge cautions against the use of latex inner tubes with carbon fibre rims. It says: “Carbon rims do not dissipate heat as well as aluminium and prolonged braking, such as on long descents, may lead to hot spots along the braking surface. This increased heat can damage the latex material leading to a failure.” Puncture resistance Sealants are a better solution. Preparations such as Slime contain small rubber particles suspended a liquid that dries on exposure to air. It’s pretty effective at sealing holes up to about 3mm across. However, it’s hard to squeeze a sealant through a standard Presta valve so sealant makers offer tubes with the fluid already inside. If you want to roll your own, then you want tubes with removable valve cores.
