Overview of KOIBIKE's 28MM Width Carbon Spoke Wheelset Series:
KOIBIKE's new developed 28mm outer width carbon spoke wheelset series offer a blend of lightweight performance, aerodynamic benefits and robust constuction, making it a popular choice for road and gravel cycling. The wheelsets are with clincher/tubeless compaibility, both disc brakes and rim brakes are available. The wider 28mm profile is designed to optimize aerodynamics with wider tires, typically in the 28c to 30c range, and provide a more comfortable ride.
With 28mm outer width clincher/tubeless designs, rim depths are available for 30/35/40/45/50/55/62mm, which are versatile for all kinds of cycling terrains from road, cyclo-cross to gravel, to meet different kinds of races, particularly for road cycling. The light weight and high stiffness carbon spokes also contribute to the wheelset's stiffness and responsiveness, while the wider rim allows for wider tires, which further enhances these benefits.
Building with the light weight and high quality 275 grams 20/20 holes hubs, making the wheelset running smoothly, faster and stable, the 3 grams carbon spokes also help to reduce the total weight significantly, all these factors make these wheelsets with light weight, high stiffness, aerodynamic and comfortable for high speed road cycling races.
