700c vs 26"
If you'll pardon the question, I'd like to know what the difference is
between a 700c wheel and a 26 inch wheel. Does 700c mean 700 cm? |

Yes those are the 7 metre high wheels that you see out on the road, the clearance will not let them on many roads so you may not have seen many of them. They have to stay on the OD truck routes and have a high load lead and follow vehicle. See also http://sheldonbrown.com/tire-sizing.html -- PiledHigher |

The "c" stands for "clincher", that is, not for tubular tyres. They're bigger in diameter than a 26" but slightly smaller than 27" I don't know what the 700 actually stands for - I initially thought it was the diameter in millimeters, but that would make it bigger than 27" which they're not. |

The nominal tyre size ie. outside diameter around the tread. Cheers Peter |

700c vs 26"
As usual, Sheldon Brown comes to the rescue in explaining tyre sizes:
http://www.sheldonbrown.com/tire-sizing.html. 700c has a bead seat diameter of 622mm, 26" MTB wheels have a bead seat diameter of 559mm. So for approximately same width tyres on the wheels, the 559 wheel is about 6cm smaller diameter. For a road frame size smaller than about 54cm or so, using smaller 650c or 26" wheels in preference to 700c means the framebuilder has to make less compromises in fitting the frame and rider around the wheels.

What I don't understand is why don't the manufacturers tell us what it means instead of leaving it up to people like Sheldon to do it for them? Why do we have to guess? The makers ought to just tell us so we can make informed decisions.

Do you really care that 700c wheels have a bead diameter of 622mm? The tyre will have 622 on it (x whatever width it is). Do you want each tyre to come with a pamphlet explaining all the sizes? Car tyres don't, so why would bike tyres? |

Car tyres don't, so why would bike tyres? Yeah, but then a car tyre's dimensions are pretty explicit AND consistant. 205/60/15 is 205mm width, 60% of width as treadwall height and goes on a 15" diameter rim. You don't get 45cm rims. 4WD tyres can depart a bit from that but they, fittingly, use truck measurements. 26" and 27" wheels made perfect sense to me, but 700C confused me as well. I'm really still working on a "they is what they is" basis with them. |

Car tyres don't, so why would bike tyres? Do you think every town has a LBS? Or even one that is conversant about tyres? And what if I see a 700B tyre? What's the difference between a C and a B? Is the B going to be suitable for my rim? And what does the 700 refer to anyway? If you measure your rim it's nothing like 700mm. Does it convert to inches somehow? If I'm swapping my singles wheel with my clincher wheel how much effect will it have on my speedo? How the hell do I know if the manufacturers won't tell me! For a while Velocity were making wrong sized rims and insisting the tyre manufacturers were making bad tyres. How do we work out who's right? I just bought a Continental ultra sport that has 700 by 23C written on it, is that the same as a 700c? Will it have the same diameter as 700 by 25? If the outside diameter is different then why do they call it 700? These are things I like to know. Marty |
