What does the C mean in 700C?
C Wheel Size Explained Now, you might be thinking what the “C” stands for — it does have a specific meaning. It’s derived from the French term “crochet,” which means “hook”. The C also shows that the wheel is meant for clincher tyres used on road bikes. The term “700c” is the tire size according to the French system. The “700” is stating the diameter of the bicycle tire and “c” is the width size of the tire. However it’s not 700 millimeters it’s 633 millimeters. Also, another common mistake is that often riders confuse “c” with centimeters.Will a 29 inch tire fit a 700C rim? While technically the same ISO size and inner diameter, most 29” tires won’t fit a 700C rim. C tires, so they can’t be installed on narrow road bike rims designed for skinny, low-volume tires.
Which is better, 23c or 25C?
Still, you seldom ever find 23C tires on modern motorcycles. C tires provide superior shock absorption for more comfort, lower rolling resistance because of a smaller contact area, lessen the possibility of punctures and pinch flats, and give overall improved stability in handling. While 23mm and 25mm tires were once the norm, you’re now more likely to see riders using 28mm, 30mm, or even wider tires, especially in certain stages of the Tour.Wider tyres, however, have a larger contact patch with the road, which increases rolling resistance and aerodynamic drag. This extra resistance means the engine has to work harder, consuming more fuel.
What’s the difference between 700x23c and 700x25c?
Tire width influences comfort and performance: 700×23 : thin and light, ideal for competition but less comfortable.Speed: There’s a trade-off between comfort and speed when choosing tire size. Narrower tires like 28mm can be faster but may not provide the same level of comfort as wider options like 32mm. Think about where you want to strike that balance.Here’s what this means for TT and tri: If your bike, and your wheel, is optimized for a 25c tire your fastest tire is probably that size. If your wheel and, ideally, the bike the wheel goes into is optimized for a 28c tire then the fastest tire is 28c.The size of a road bike tire is normally shown as the wheel diameter alongside the tire width – e. In this example, 28c refers to the tire being 28mm wide. Dimensions are printed clearly on the sidewall of the tire.
What does 700x23c mean?
French system’. The first number, 700, refers to the nominal diameter of the bike tire and is measured using millimeters. The second number, 23, is actually the width of the bike tire, again it’s measured in millimeters. Will 27. Rims Fit My 700C Bike? In most cases, yes—but there are a few things to check: Brake compatibility: If you’re using rim brakes, the brake pads must align with the new wheel’s rim. This usually limits the swap to disc brake bikes.The 23 & 28 denote different tire widths, not tire diameter. Both of these will fit the same diameter rim (700). However the 23c usually is installed on 19mm to 23mm wide rims. The 28c will fit on 19mm & 23mm as well, but can be installed on wider rims like 25mm.
What’s the difference between 23C and 25c tyres?
If you mount a 23C tyre on a narrow rim, it will shape into a rounded profile. This creates a more unbalanced aerodynamic package, compared a wider 25- or 28C tyre, when inflated on an appropriately sized rim. The Rule of 105 states that the rim must be at least 105% the width of the tire if you have any chance of re-capturing airflow from the tire and controlling it or smoothing it. One of the most interesting aspects of the Rule of 105 is that before 2001, nobody was tunnel testing with 21 or 23mm tires.Time was, only a few years ago, that pros raced on tubular tyres at around 23mm wide, pumped up to 100psi or more (that’s over 7 bar). But now, even in races on tarmac, it’s typical to see riders on 28mm or wider tyres, which are likely to measure up even wider on modern wide aero rims.
