The strong crosswinds and demanding course at the Kona Ironman World Championships restrict the use of traditional disc wheels, while various time trial and triathlon courses also test a wheel's aerodynamics, stability, and efficiency. This ultimate testing ground for the world's top athletes gave rise to our Koi58 wheelset, designed specifically for elite riders. This is a triathlon/time trial-specific wheel that defies limitations, redefining speed in any condition, pushing speed, stability, and control to the extreme.
Full-Disc Rear Wheel
The full-disc rear wheel's unique integrated structure allows airflow to adhere closely to the wheel surface, completing the entire flow process in one go. Whether at high speeds or facing complex wind changes, this close fit ensures airflow stability, reducing wind resistance caused by air separation and turbulence, creating a smoother riding environment for the rider.
Lightness: Extremely Lightweight at 950 ± 30g
In competitive sports where speed and control are paramount, the DW-700CX28TL-R-ULwheels, with their ultra-light weight of just 950 ± 30g, are like a weight that takes the weight off a bicycle, allowing it to zip along the track with ease. When an athlete pedals, the lighter wheels have less inertia to overcome, allowing them to respond more quickly to their power output and achieve faster acceleration. This acceleration advantage is particularly pronounced during short sprints, allowing athletes to quickly accelerate, seize the lead, and leave their opponents far behind.
The DW-700CX28TL-R-UL dedicated rim is now available with a disc brake rear wheel. With an external width of 28mm and an internal width of 21mm, it's seamlessly compatible with 25c-40c tires.
From the gusty winds of Kona to the unpredictable nature of training rides, triathletes are constantly searching for equipment that helps them push their limits in the pursuit of athletic excellence. Koibike wheels are the ideal choice. Their exceptional stability allows you to navigate strong winds and challenging terrain with ease, while their ultra-lightweight design gives you a lighter feel and superior acceleration.
