Cork Handlebar Grips
Descrição
The bicycle handlebar grips are made with agglomerated cork, elegant and very comfortable. A good alternative to conventional bicycle handles.
You could not find a better natural material than cork, as it guarantees a comfortable ride, it is a bicycle handlebar grip that absorbs shock from road irregularities, thanks to the properties of cork. A perfect bicycle accessory for daily commuting, a piece that adds a natural design detail to your bike.

What cork is made of?
Cork is made up of suberin cells in the shape of a tiny pentagonal or hexagonal prism, a complex fatty acid filled with a gas similar to air, which occupies around 90% of its volume. It has an average density of around 200 kg/m3 and low thermal conductivity.
Chemical composition of cork:
* suberin (45%) - main component of cell walls, responsible for cork elasticity;
* lignin (27%) - insulating compound;
* polysaccharides (12%) – components of the cell wall that help define the cork texture;
* tannins (6%) - polyphenolic compounds responsible for color;
* ceroids (5%) - hydrophobic compounds that guarantee the impermeability of cork.
Main characteristics of cork:
Lightness
Cork is a very light raw material, weighing just 0.16 grams per cubic centimeter and floats.A cortiça é uma matéria-prima muito leve, pesa apenas 0,16 gramas por centímetro cúbico e flutua.
Flexibility/compressibility
Each cork stopper is made up of around 800 million watertight cells. Between them there is a gaseous mixture that allows compression to approximately half its width, without loss of flexibility and decompression and return to the original shape. This is called elastic memory. Cork is the only solid that, when compressed on one side, does not increase in volume on the other. This feature allows it to adapt to variations in temperature and pressure without compromising its integrity as a sealant.
Impermeabilidade
Thanks to suberin and ceroids, it is practically impermeable to liquids and gases.
Imputrescibility
Cork is highly resistant to humidity and, therefore, also to oxidation and rot.
Isolation
Cork is an excellent thermal, acoustic and vibration insulator. When transformed into corks, their insulating properties contribute to better protection of wines and spirits against temperature variations or contamination and against possible negative effects of storage and transport conditions.
In construction, it has clear advantages in terms of construction quality, internal air and comfort, and can be used for waterproofing infrastructures, foundations and subfloors, for acoustic and thermal insulation and for the final coating of floors, walls, ceilings, facades and roofs.
Recyclable and renewable
Cork is a natural raw material, 100% recyclable and renewable.
