2018年6月17日 · In short - the 700x25C is a French nomenclature for tire size meaning tire diameter of 700mm and tire width 25mm and C is the width of the rim (A is very narrow, D is wide). Thus the number between "x" and "C" is the tire width in mm. For more information you can read a section on tire sizing on Sheldon Brown page.

2018年1月31日 · Given its a road bike this question is more about frame clearances than whether 28 is an acceptable replacement for 23. Your easiest option is to buy a single cheaper 28mm tyre and fit it, see how it goes. I have about 1mm of clearance at the brake bridge on my road bike with 28, its only barely enough... but it is just enough. –

2015年7月28日 · I have a cyclocross bike with Alex ATD 470 Disc rim with TCS (Tubeless Compatible System) currently mounted with Vittoria, Cross XN, 700 x 32c tires. However tires are a bit worn out and I want to be driving a bit off road during the winter.

2023年5月15日 · One runs 28-32mm, and the other 35-38mm. I'd much rather not have to worry about whether I'm carrying the right spare tube, or what size my patched ones are (not all brands label them permanently). I can't cover my gravel wheelset with the same tubes, unfortunately.

2017年1月2日 · Finally, the real answer: If you swap between 25 and 28 and set the tire pressures appropriately, most people (esp. non-racers) will not notice a difference in performance. The 28 will be a bit more comfortable since its running at a lower pressure. For a 50 x 11, at 80 rpm, you're looking at 28.5 (25c) vs 28.9 mph (28c).

2016年6月2日 · 700 x 25-32cc. Which I think is the one that I want. The picture of the box (not necessarily correlated to my choice in sizing) has the text. 20-622 > 25-630. Which again seems to confirm that this inner tube will be correct. Will the tube size mentioned above fit …

2011年2月15日 · 700 is the size of the wheel and tire which the tube is intended to fit. In this case, 700 means 700c, or ISO diameter 622mm rims. If you are unfamiliar with tire sizes, take a look here. 28/32 designates the min/max range of width of …

Fortunately though, this is changing and now many road bikes brag about being able to fit up to 700c x 45 mm OR 650b x 2.1" tires. – Paul H Commented Mar 18, 2019 at 21:17

2016年7月8日 · I can confirm 29er rims can be used with 700c tires, I have done it twice. I once assembled a dutch bike using a frame designed for 28" wheels using rims labelled for 29" mountain bikes, and 700c x 35 tires. The size is close enough to a 28" assembled rim+tire. However, a 28" tire has a bead 4 milimetres or such too big to fit a 622 rim.

2019年3月29日 · A 700 x 18-23c would probably work fine, especially if the tire is a "small" 25. Bicycle tire and tube sizing is a bit of a crapshoot - one manufacturer's "25" can be a a mm or two larger or smaller than another manufacturer's "25".
