A folding bead is the type of tire bead that allows the tire to fold when being removed from the rim. This characteristic is a key difference from tires with a wire bead, which are rigid and cannot be folded.
Understanding Folding Beads
The bead of a bicycle tire is the edge that hooks onto the rim of the wheel. Traditionally, this bead is made from stiff steel wire, making the tire rigid and unable to be folded or compressed significantly.
In contrast, a folding bead typically uses a different material, such as Kevlar or aramid fibers, which is strong but flexible. This flexibility allows the tire bead to be folded or rolled up, making the tire much more compact.
Why Use Folding Beads?
The primary advantage of a folding bead is weight savings. The flexible material used in the bead is lighter than the steel wire found in non-folding tires. For cyclists focused on performance, even small reductions in weight can be significant.
Example Usage:
- "I'm replacing my old tires with folding beads to save some weight."
This example highlights the practical application for cyclists looking to lighten their bike.
Where and By Whom Are Folding Beads Used?
Folding bead tires are particularly popular within specific cycling disciplines and among certain types of riders.
Here's a quick look:
| Area of Use | Target User | Key Benefit |
|---|---|---|
| Mountain Biking | Serious Cyclists Who Want to Save Weight | Reduced Weight |
| Road Cycling | Serious Cyclists Who Want to Save Weight | Reduced Rotating Mass |
As indicated, they are most used in Mountain biking and road cycling and most used by Serious cyclists who want to save weight on their bikes. The ability to fold also makes them easier to carry as spares on long rides.
In summary, a folding bead refers to a tire construction that utilizes a flexible material in the bead, enabling the tire to fold. This design is primarily favored by serious cyclists in mountain biking and road cycling for its weight-saving benefits.
