Another way to get the brakes closer to the rim is to use V-brake clamp-on bosses and install them a bit higher than the original ones. V-brakes that allow you adjust the height of the pad work too.
If you know an experienced steel frame builder, you could pay him to cut the old V-brake bosses and weld a set of new ones a bit higher. Make sure that the person in question has the necessary experience to complete the task. Otherwise, your safety will be compromised. In some situations, it may also be possible to install caliper road brakes. This can only be done if the fork is rigid and has a hole for a fender.
The frame needs to have a mounting hole for a fender or a reflector too. This set-up is likely to have poor reach because the mounting holes on the fork and the frame are often too far above the wheels. Long-reach caliper brakes are the only solution.
As long as the new wheels have rotors designed for the calipers that you have, the installation process should be fairly straightforward.
In some cases, people even store two sets of wheels and swap them according to the ride ahead. The Over-Locknut Dimens ion O. The term O. The O. Standard road bikes with caliper brakes have a rear O. New rear road bike wheels designed for disc brakes tend to have mm O. If your rear wheel has mm O. When the O. In this case, the hub is a bit 5mm shorter than the requirement. Proceed at your own risk. A common advice is to put two 2.
In consequence, the cassette ends up behind in relation to where it would be if the hub had mm O. This has a negative effect on the chain line. Another option is to put a 5mm spacer on the non-drive side of the wheel. This method ensures a straight chain line because the cassette will assume its appropriate place. However, this method comes with issues too. First, the entire wheel gets closer to the chainstay of the drive side and may even rub against the frame depending on how big the tire is.
To fix this issue, the wheel will have to be re-dished re-centered. Note: Another downside of this method is that the axle protrusion on the non-drive side will be reduced by 5mm. Most quick release axles are designed to leave 5. When you add the spacers, the non-drive side will be left with just 0. You'll also find C tires on some European-style cruiser bikes.
The "" refers to the rough outer diameter of the tire, although the actual outer diameter will vary greatly, depending on the type of tire and tread pattern. And don't say "CC" unless you want to look like a complete newbie. Most high-performance road bike tires have a width of 23 or 25 millimeters, although some are as narrow as 18mm or as wide as 28mm. Cyclocross and touring tires range from 28mm to 38mm although the maximum width for officially-sanctioned cyclocross events is 32mm , and hybrid bikes use tires 35mm to 45mm.
You'll find the size printed on the side of most tires, e. Sometimes, the manufacturers will put the "C" after the width number, e. To make matters even more confusing, sometimes the size is printed on the tire as the width followed by the BSD, e.
Some older road bikes mid 's and earlier used inch tires; these were used on most of the "speed" bikes that many of us grew up with. These are NOT the same as the C tires found on modern road bikes.
Very few, if any, modern bikes are manufactured using the inch tire size, but replacement tires, inner tubes, and wheels are still available for those older bikes.
However, you can NOT use a inch tire on a C wheel, and vice-versa. Some time after the mountain bike boom in the mid's, somebody got the idea, "Hey, why don't we pick a tire size that's better suited to the way mountain bikes are used? The resulting tires ended up having an outer diameter of around 29 inches, so these bikes and the tires are now referred to as " 29ers.
Similar to inch mountain tires, 29er tires typically range from 1. By general agreement within the bike industry, the size of 29er tires is usually printed using the "English" measurements, e. Some time after the mini-boom of 29er mountain bikes occured, there were some people in the bike world who felt that the larger 29er wheel had some disadvantages. Whether these disadvantages are real or perceived is a matter of differing opinions, but regardless, detractors of the 29er felt that a "happy medium" tire size between 26 and 29 was needed to provide "the best of both worlds.
Only a handful of companies are making B bicycles, and the selection of tires is rather limited. Some small sizes of women's-specific road bikes use a tire size known as C. This size was also used on some triathlon bikes a few years back, but this is becoming less common.
Inner tubes made for narrow inch tires e. Create a free Team What is Teams? Learn more. How do I know if I can replace the 27 inch wheels with c wheels on my bike? Ask Question.

Yeah, you'd have to get new wheels.
And then you hope that the brakes will still work. Add a comment. Active Oldest Votes. Improve this answer. THAT would be extra work Believe it or not, that was something I considered with a past rebuild.
But you can't reposition where the front brake attaches and I was hesitant to jimi-rig an adapter for something crucial like the brakes.
You will probably need to drop your brake calipers. Despite fitting long-reach Tektro R calipers, the back wheel looked like this: There might have been another millimetre by fiddling, but not the difference I needed. Please ignore the dodgy-looking cracked tyre sidewalls Here's the drop-plate I made from 6mm of scrap aluminium bar. Fitting that with lots of copper grease and some solid bolts gives this: Curiously, the same brake on the front reached the wheel rim perfectly without any crafting.
I should have lowered it even more, but this way there's clearance for a mudguard someday. DanS DanS 1 1 gold badge 4 4 silver badges 8 8 bronze badges.
