Is a bike tube the same size as the tire?
The tube should match the tire size diameter closely. However, tires that are close in bead diameter may use the same inner tube. For example, an inner tube for an ISO 630 tire (27-inch) will also fit an ISO 622 (700c) tire.
What size tube fits a 700x35c tire?
Here’s the quick answer: Pick a tube that says 700 x [Width range], where the width range includes 35. For example, a tube that says “700×35-42” would be perfect for your bike.
Does inner tube width matter?
No, tubes and tires don’t need to match exactly. Tubes are made from butyl rubber which can stretch. Bike inner tubes will accommodate a limited range of sizes. Larger tubes may be more susceptible to getting pinched between the tire and rim.
How much does a bike inner tube cost?
The average price of a bike tube costs between $5 and $9. You can find tubes for as little as $2 and up and even some models beyond the $35. Specialized tubes and puncture-resistant tubes will cost more than traditional bike tubes.
How do they measure bike size?
Adult bikes are measured by their frame size. Most manufacturers now measure the frame from the centre of the crank axle, to the top of the seat tube. Most road bikes are measured in centimetres (cm), whereas mountain bikes are generally measured using inches (in).
Do bike tire tubes have to be exact?
Since tubes are flexible and stretchy, they’re typically sold in a range of widths. You just need to make sure the tire diameter for the tube is exact. While these are a few of the common tube widths you may see at stores and online retailers — like REI and Amazon — always go by what’s written on your bike.
Is 27.5 the same as 700C?
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.
What size is a 700C bike tube?
27-inch and 700C tires are close enough in size that the inner tubes are compatible; i.e. you can use a 27-inch inner tube in a 700C tire, and vice-versa. However, you can NOT use a 27-inch tire on a 700C wheel, and vice-versa.
Is 26 inch the same as 700c?
A 26 inch, or a 650c wheel is about 1 inch smaller (about 2 inches smaller with road slicks) in diameter than a 700c. Some people think that because 700c wheels are the ‘standard’ for road bikes, they must be better.
Is a 28 inch wheel the same as 700c?
The wheel sizes 28”, 700C and 29er or 29” all refer to the same rim size: ETRTO 622. 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.
Will a 26 inch tube fit a 700c?
It’ ll work fine. It ‘could’ work if the 700c tube diameter is similar to the 26 inch. Some 700c are quite small, and some 26 are very large. Another concern is the size of the hole for the valve stem.
Can I use a smaller diameter inner tube?
Yes, you can, as long as you don’t go more than one size smaller, or the differential is not too extreme. A 1.25 in a 1.5 is fine. A 1.25 in a 2.25 is likely to have issues with flats. Your LBS will have tubes.
What size inner tube do I need for 700x38c?
What bike inner tubes should I buy? When choosing an inner tube, you need to select a tube that has the diameter shown on your tire (in our case, “700”) and a width range that includes the diameter you need (“38”).
