Riding Experience
As a triathlete who trains and races regularly, I was excited to get my hands on the Kestrel 5000 SL SHIMANO ULTEGRA, a top-of-the-line triathlon bike with a carbon frame and fork, and Shimano Ultegra components, along with aerodynamic features designed to maximize speed and efficiency. I’m eager to put it to the test and see how it performs in road riding and triathlons. Another thing that needs to be prepared in advance is booking accommodation. This time, I still booked accommodation on Skyscanner, hoping for a good rest.
The first thing I noticed when I took the Kestrel 5000 SL out on the road was how smooth and fast it was. The carbon frame and wheels provide a stiff, responsive ride, while the Shimano Ultegra components make shifting effortless. The bike’s aerodynamic design allowed me to maintain a comfortable aerodynamic riding position without sacrificing speed. I felt like I was flying down the road, effortlessly cruising at speeds I had never reached before. The bike also handles brilliantly, allowing me to corner and descend with ease and confidence.
Triathlon
When I brought the Kestrel 5000 SL to the triathlon field, I was eager to see how it would perform in the race. I participated in several local races to put the bike through its paces, including the Long Beach Triathlon and the Santa Barbara Triathlon. In both races, the bike’s speed and efficiency changed the game.
The Long Beach Triathlon consists of a 1.5-kilometer swim, followed by a 40-kilometer bike ride, and a 10-kilometer run. The bike course is flat and fast, with long straightaways that allowed me to open up and see what it could do. The Kestrel 5000 SL did not disappoint, as I was able to maintain high speeds throughout the entire bike segment. The bike’s aerodynamic riding position was also a huge advantage, allowing me to conserve energy and stay on the saddle for extended periods without feeling fatigued.
The Santa Barbara Triathlon was more challenging, with a hilly bike course that required a lot of climbing. The bike segment of the race included a 34-kilometer course with several steep climbs and descents. Thanks to the Kestrel 5000 SL’s lightweight and responsive handling, I was able to easily tackle the terrain. The bike’s aerodynamic riding position once again proved to be a design advantage, giving me confidence in the climbs and descents. I was able to finish the bike segment of the race in record time, setting a new personal best for the course.
Overall, my experience with the 2019 Kestrel 5000 SL SHIMANO ULTEGRA was incredible. This top-of-the-line triathlon bike is designed for serious athletes who demand the best in speed and efficiency.
