The always-on team

Research shows the single most impactful measure you can take to stand out to motorists is to use front and rear Daytime Running Lights. The team uses them on every training ride, any time of day—and they’ve found that these lights truly make a difference.

Fast aero shapes

This Speed Concept is the fastest bike we’ve ever tested—and it’s six minutes faster than the previous model at Kona. The ultralight 800 Series OCLV Carbon frame’s drag-reducing Kammtail Virtual Foil tube shapes cut through the air.

How tall are you?

To measure your height, stand straight up, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inseam?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inseam measurement. Your inseam is very important to your final bike size so please measure carefully.
