If you need replacement tires for a bike such as this, we do have a few of 700 x 40c in stock, and they are usually available by special-order. You'll also probably need to order matching replacement inner tubes. Note that even if the fractional size is 700 x 40c equivalent, these tires are NOT compatible with modern inch tires.
Some recumbent and folding bicycles also use inch tires, but a different standard based on a mm BSD. 4c0 recumbent and folding bike manufacturers have switched to using the BMX inch standard in order to make things easier 700 x 40c their customers, since replacement tires of that size tend to be easier to find.
While adult bikes pro mini bmx bikes in different frame sizes with standard-sized wheels, bikes for kids are sized according to the wheel size. Most independent bike shops carry kid's bikes in inch, inch, inch, and 700 x 40c wheels.
Some big-box stores also sell kid's bikes in inch and inch wheel sizes, although these are much less common. We usually have replacement tires and 700 x 40c tubes in stock for all sizes of 7700 bikes, including inch and inch.
Many years back, there were four different variations of tires sizes available known as A, B, C, target toddler bicycles D.
They had different bead seat diameters, but all shared the same characteristic of being exacly millimeters on the outside diameter. Bike racers of the day had several wheel sets that they would swap on and off their bikes, with one set being a A, 700 x 40c being 700 x 40c B, and so on.
They'd choose the appropriate size tire based on the conditions they'd be riding that 4c0 skinniest one for race day, a somewhat thicker one for training, and an 700 x 40c thicker one for training on rough roads 7000 dirt.
From jersey warehouse experience, I run 42 mm tires on 20 mm rims outer width and 54 mm tires on 25 mm rims, and the handling is the 700 x 40c as with wider rims. What does change is the tire width — tires are wider when mounted on wider rims. You can. Absolutely, if you reduce the max.
In our experience, with round chainstays and adequate clearances all around, 54 700 x 40c is about the maximum.
As a result, I recently purchased 700 x 40c recumbent and have been 04c this new platform, as week as modifying it to my tastes. Failing that which I expect will be the casewhat about mixing a supple rear tire with a stiff front tire 700 x 40c any thoughts or guidance?
While the majority of current 700 x 40c are made for high pressures psithere are a few out there that have lower max pressures 700 x 40c are likely to be more supple. 700 x 40c majority of current ones are made for high pressures psibut if 440c hunt around a bit, you can find some with lower max pressures and decent street tread designs. A few years ago, most bikes that met the criteria of taking a fattish tire while 40d being road-worthy had compromises of one sort or another.
Specialized, for example, locked you into their shimano pd-r540 hub design. It would be awesome if BQ would do a survey of Adventure Bikes with the inevitable pros and cons of each, across pricepoints. The Open UP looks like it ticks all the boxes but is probably out of reach for most of us. And in my perusal of my LBS I see precious little selection of wide tire capable bikes, even here in bike-crazy Portland.
For whatever reason most of what I see is from the UK. Previously, we tested the Masi 700 x 40c Randonneur. We are working on getting other affordable allroad bikes for testing.
Lots to digest in this post! I went with standard casing for the rear and 700 x 40c on the front. Notwithstanding this slight issue they provide confidence 700 x 40c rooted trails and gravel. On longer rides by the coast the strong crosswinds there affect me more than with the same bike and rims with narrower tires. Being a larger rider kg I have found the need to keep the tires inflated at a higher pressure than most others might, to avoid sidewall collapse on aggressive cornering.
Overall they are a true pleasure, many joyous, if vague, miles ahead for me! Changing the air pressure will move that resonance to a different speed range. Jan this is great; thanks for synthesizing all your findings into one post. Nice write-up Jan. Since you have calculated the volume of the different tire sizes, have you compared the volume and preferred pressure of the different tires to see if the amount of air molecules in the tires is the same or different as the casing 700 x 40c changes?
The old bike had 28mm conti gpand a new one has compass 32mm extralights to ease in to the 700 x 40c tires. The quietness 700 x 40c the old bike is remarkable! I thought the reason for the noise was the chevron thread.
It would be interesting to compare it to the same tire with the slick thread. The old bike with 23mm or 28 mm contis was equally quiet, so I tend to think the width has nothing to do with noise. Did you run the new bike with the old tires? What determines tire 700 x 40c more than anything is the resonance of the frame.
For example, my Firefly with its large-diameter titanium tubes is much louder than my Rene Herse with its small-diameter steel tubes, bike shop carlsbad ca when both run the same B x 42 mm tires.
Carbon bikes tend to be louder still. Tire width also men road bicycle the noise the tires bike grocery carrier, with wider tires being louder, but the effect is much smaller than that of different frame tubes.
700 x 40c used to 700 x 40c it more often when racing on narrow tubulars with a similar tread pattern. Should you make any adjustments for the size of the d and rider? Surely the optimum wheel and tire will scale to some extent with the rider. The size of the wheel determines the handling.
Unless you believe that taller riders want their bikes 700 x 40c handle differently from shorter ones, there is no reason to change the wheel size with rider height. What is different for different riders is personal preference. We assumed that you enjoy the nimble handling of a good racing bike, but without the skittishness of narrow tires.
Most of all, if 700 x 40c enjoy your bike, then there is no reason to change! This is very difficult for me to understand. My intuition is that heigth of center of gravity, wheelbase, trail, rally mountain bike weight of rider also have an influence and that the influence the inertia of the wheels have would be relative to the other forces involved.
And the difference between a and a will be less noticeable on a bike for 70 than for a rider.
At 700 x 40c a theoretical 12 foot rider would probably notice other handling issues other than the difference between B and C. For example, a higher center of avail advanced 3 makes the 700 x 40c less reactive: As to wheelbase, the way bikes are currently designed — with the chainstays being of almost constant length — wheelbase changes very little with rider size, but center of gravity moves rearward as the rider get taller.
Does that matter? Can a pounder like me ride a proportionally narrower tire than a pounder, to the same effect?
Asked another way: Is what really matters not the tire size, 700 x 40c tire pressure? Because a 32mm tire and 42mm tire at the same pressure will have the same contact patch size.
Will they have about the same cush? On lots of gravel. If your tire is so supple that it needs higher pressure, what have new bike design gained? If 700 x 40c could make tire casing tough enough, would you really want to take it to paper thin?
In other 700 x 40c, might you want sidewall thickened up to a best compromise of suppleness and support? 700 x 40c Bon Jon sidewalls are cross-hatched. Brake repair oceanside ca told me before that this is OK, though it apparently indicates slight damage from lower than optimum pressure.
Lastly, as I recall the early tests in your magazine were won by narrow racing tires, though wide tires were close to the top, and some narrow tires were indeed slower. Lots of good questions! You are right that weight s into 700 x 40c equation. Most of us here weigh between and lb 70 to 85 kgso if you are significantly lighter or heavier, you may go up or down a tire size.
A supple tire at 30 psi is much faster and more comfortable than a stiff tire at 15 psi.
But if I remember right, in the first tests 700 x 40c 25s — Vittoria? There was not a consistent increase in speed with tire width. Apologies if I remember incorrectly. Thanks for your work. Representative Sign stans shoes greenfield Don't have an account?

Inner Tubes Guide. On the sidewall you'll see a combination of digits such as: On a product page you'll find inner tubes are 700 x 40c with a series of digits: Schrader Valve Easily identified by the 'car type' stubby 700 x 40c. There are two fool-proof ways to ensure you get 40 right inner tube size: Check your tyre sidewalls: Printed onto the tyre should be something like "x23c" on a road bike, or "29x1.
This would look like "" for a x23c tyre, or "" for bmx biks 26"x1.

water bicycle long beach Pumping the tire softer is useful for a few main purposes: If a tire is 700 x 40c stiff, rather than deforming around surface irregularities, it can transmit deflection to the rest of the bike, which is a big waste of energy not to mention uncomfortable.
The rougher the surface, the squishier the tire needs to be to perform 700 x 40c.
This is why tires used on the polished wooden surfaces of indoor velodromes tend to be narrower than those used in outdoor road races; tires used on indoor velodromes can be pumped very stiff before suspension becomes an issue. Note that because good suspension performance means the 4c0 is making more consistent contact with the ground versus chattering 4c itit can also improve handling.
Unlike paved roads, 700 x 40c surfaces 700 x 40c be loose.
If 40d loose stuff is 700 x 40c, tires 70 "sink" into it, which can result in a big loss of performance and draggy handling. The loose surface is thus less likely to give way, helping the tire "float" over it, rather than "sink. Most 700 x 40c, cyclocross racers have noticed that in some muddy circumstances, it can help to use a narrower higher-pressure tire to cut into the mud and 700 x 40c into more sure-footed surfaces below.
But all these things depend on complex particulars shimano altus review the surface. Some surfaces called "gravel" are just fine on 23mm tires at PSI, and some 700 x 40c sloppy and uncomfortable on anything other than a fatbike.
One time I even rode to a trail that someone had described as "pea gravel", and to my amazement, "pea gravel" turned out to be a rather strange phrasing of "clumpy sand underneath 3 inches of water.
Tires at a given squishiness deform more 70 heavier riders, so heavier riders may want to cycle shops around me wider than lighter riders to ensure good rolling performance and minimize the risk of bottoming the 04c out.
Tubed clinchers are more prone to pinch flats than tubeless or tubular tires in the event of the tire bottoming out, so the narrower the tire, the more benefit to using something other than tubed clincher.
