Apr 26, - C to b conversion, Advocate Lorax, compass tires . medium Advocate Lorax, a bike designed around C x 38mm tires, and an already adept gravel bike. If not, you'll have to decide whether it's worth the trouble.
This page covers sizes in common use as of its writing, and a number of older sizes. Sutherland's Handbook for Bicycle Mechanics3rd through 6th edition, covers dozens of additional, antique sizes. Better bike shops have a copy. The traditional sizing systems are based on a measurement of the outside diameter of a tire.
This would usually be measured in inches 26", 27", etc. Unfortunately, evolution 700c 38 tires tires and rims has made best bikes for long rides measurements lose contact with reality.
Here's how it works: Let's start with the 26 x 2. This size tire is very close to 26 inches in actual diameter. Some riders, however were dissatisfied with these tires, and wanted something a bit lighter best vintage road bikes faster.
The 700c 38 tires responded by making "middleweight" tires marked 26 x 1. This same rim 700c 38 tires was adopted by the early pioneers of west-coast "klunkers", and became the standard for mountain bikes. A second number or letter code would indicate the width of the tire.
Inch-based designations sometimes tirrs the width in 700c 38 tires decimal 26 x 1. This is the most common cause of mismatches. Although these size designations are mathematically equal, they refer to different 700c 38 tires tires, which 700f NOT interchangeable. It is dangerous to generalize when talking about tire sizing, but I would confidently state the following:. If two tires are marked with sizes that are mathematically equal, but one is expressed as flat bar road bikes decimal and the other as a fractionthese two tires will not be interchangeable.
Competitive pressures have often led to lamps plus chandler az in width measurement.
Suppose you are in the market for a high-performance x 25 tire; you might reasonably investigate catalogues and advertisements to try to find the lightest available. If the Pepsi Tire Company and the Coke Tire Company had tires of equal 700c 38 tires and technology, 700c 38 tires the Pepsi was actually a marked as a 25, the Pepsi tire would ties lighter than the accurately-marked Coke This would put Pepsi at a competitive advantage.
In self defense, Coke 700c 38 tires retaliate by marketing an even lighter labeled as a This scenario prevailed throughout the '70's and '80's.
The tiree got so out-of-hand that cooler heads have prevailed, and tirds is a strong but not universal trend toward accurate width measurements. Maxxis Minion 26 x 2.

In addition, reducing the rim diameter allows a bike to maintain better handling characteristics and react more quickly 700c 38 tires rider input. With that said, B works for taller riders as well. Conversely, if a bike was designed around C x 45mm tires and you switch to B x 47mm, the gravel bikes 2018 bracket will likely be far too 700c 38 tires.
Here are five useful equivalents:.
Consider these 700c 38 tires reasons…. As tire size goes up, so does gearing. Not only is going to the smaller B diameter with large volume tires good for keeping low gearing, but it also keeps tiress roughly the same as what road riders are used to.
More air and rubber, same gear ratios.
700c 38 tires Toe Clearance, Low Overlap Toe overlap is a term for shoe interference from the tirrs tire, usually experienced at slower speeds when pedaling technical terrain or during maneuvers that require tight turning.
Most drop-bar bikes with 20 bike trainer tires 700c 38 tires have a little toe overlap, but there is definitely a point at which it can become a burden.
With the same diameter as a C x 28mm tire, a B x 48mm tire can provide tirres the goods without risking excessive toe overlap.
There are a few other inherent advantages to moving from 700c 38 tires best buy oceanside ca B. For 700c 38 tires, shorter spoke 700c 38 tires make stronger wheels.
By virtue, smaller wheels should be stiffer, too, which means more responsive pedaling. In addition, smaller rims and wheels mean less metal was used to make the rims and spokes, which should translate to a tkres wheel. Smaller wheels and tires free up more room for seat bags and handlebar bags too. And, last but not least, they make packing a bike easier for travel or shipping.
Before the current 700c 38 tires of new B production drop-bar bikes, B was largely relegated to small frame builders, randonneuring enthusiasts, tinkerers, and folks interested in converting older road bikes to get some of the big tire secret sauce. The most common and appropriate B conversions involve a C bike built around mm tires. For this project, we used a size medium Advocate Loraxa bike designed around C x 38mm tires, and an already bike accessories set gravel bike.
But the Lorax maxes out at 40mm tires in C and more volume was needed. This leads us to the first factor to consider before tackling a B conversion: If your bike was designed 700c 38 tires such a tire, or a mm tire, B conversion might be appropriate. And, even if you have a bike designed around C x mm tires, it is still a possibility, but bottom bracket height and tire width clearance might be issues.
Either way, there are 700c 38 tires few preliminary details to evaluate:. Brakes are most hardline obstacle when switching from C mm to B mm wheels. To establish the required brake reach, measure 700c 38 tires reach with the original C wheels and add 19mm. The widest point in a B x mm tire is about mm from center of the rear axle. Bike tire valve stem repair Lorax has 63mm, which left a comfortable 8mm on each side of the tire as breathing room.
But, what about the actual numbers? What makes a BB height short enough that pedal strikes and cornering will be an issue? All four are specced with 47mm WTB Byways. One thing to remember with wider tires is that they have more tire drop—more deflection under load.
