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.
Can you use smaller size inner tube?
Can I use a smaller or bigger inner tube than the tire? An inner tube that is 10 millimeters or half an inch wider or narrower can be used as long as it matches the rim diameter. A 700×25 inner tube works in a 700X32 tire, but in a 700X45 could experience issues.
Does bike tube have to be exact size?
While your diameter measurement needs to be exact, your width measurement does not. Because inner tubes stretch, they typically come in a range of widths. For example, one of our most popular tubes is the 26 x 1.75-2.125” which means it fits a 26-inch diameter tire with a width in the range of 1.75 to 2.125 inches.
Can you put a 26-inch tube in a 24 inch tire?
Condensed answer: Most 24-inch bikes are too small and narrow to accommodate a 26-inch wheel unless the model is specifically designed for multiple wheel sizes.
Does tube size match tire size?
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 happens if you use a smaller inner tube?
Going with a smaller tube could save ~20grams of weight per tube. While the weight savings are nice, one drawback is the loss of tire pressure. Smaller tubes become stretched and don’t hold air quite as well. Some rides will say a smaller tube that is stretched will be more prone to punctures.
How do I know if my bike tube is too big?
If the tyre is a 700c x 23 or 25, then you should be OK. If it is anything larger than a 25, then you are pushing your luck a little, the tube is going to be very stretched inside that tyre.
How do I know what size tube my bike needs?
The best way to check what size inner tube you need is to look on the sidewall of your tyre. Tyre manufacturers print the size on the sidewalls, so look out for numbers such as ‘700x23c’ for a road bike, or ’26×1. 75′ which is for mountain bikes.
Can I replace Schrader tube with Presta?
You can put a Presta-specific tube in a rim drilled for Schrader valves, but it’s not advisable for anything more than an emergency fix. Tubes and tires tend to move slightly on the rim. In the wider Schrader hole, a Presta can move around enough that the rim will actually cut the tube at the base of the valve.
What size inner tube do I need for 700x40c?
Since the size of an inner tube can vary depending on the amount of air that you fill it up with, they are sold by a range of sizes that they will definitely fit. So if you have bike tires that are 700 x 40C, you need to get inner tubes which come with a size range of 700 x 35 c to 70 x 43c.
What size person fits a 24 inch bike?

What is the difference between 24 and 26 inch bike?
What is the difference between a 24 inch bike and a 26 inch bike? 26 inch bikes have more tire clearance and a longer wheelbase than 24 inch bikes, which makes them easier to ride for taller riders. 26 inch frames are typically lighter and stiffer in order to compensate for the larger diameter tires they use.
Can you put 29 inch wheels on a 26 inch bike?
Yes, it is possible to mount 29 inch (29er) wheels onto a modified full suspension 26” mountain bike frame. … In addition to this, while there are many potential advantages to 29er tires as compared to smaller mountain bike tires, you may not get all of the full benefits without using a 29er frame.
Will a 1.75 tube fit a 1.95 tire?
a 1.5″ tube will work in 1.95″ tires, but likely won’t last as long. Larger tires will cause more issues (don’t try 1.5″ tubes in 2.3″ tires if you want the tubes to last a ride).
What does 700x28c mean?
700x28c simply means the size of your bicycle tire, according to what’s known as the ‘French system’. “700” is the overall diameter of the bike tire, measured in millimeters. … The “c” is part of the old French system that classified widths of tires from “a” (being the narrowest) to “d” (which was the widest).
Will a 27.5 tube fit a 29 wheel?
They will both fit into 29, but at a stretch, literally. I’d not use it as a permanent fix, but as an emergency get you home with no alternatives, you’d probably be ok.
