The world’s first time trial-specific shoe, the Bont Cycling Crono MK2 is the second generation designed to go even faster than its predecessor – the original deemed illegal by UCI for use in competition and sanctioned events because it was too fast! The Crono MK2 represents the pinnacle of Bont Cycling's performance-based lineup and is designed for pure unadulterated speed.

Aerodynamic testing has always been about the relationship between rider and machine but at Bont Cycling, the thought of covering shoes with a simple bootie or 'aero' sock felt like a solution to a challenge that demanded a better answer.

The Crono MK2 takes one of the fastest moving objects on the bike – your feet – and transforms it into one of the most effective air-slicing pieces of equipment you can acquire without stepping into a wind tunnel. Of course, the Crono MK2 is about far more than just aerodynamics and is backed by Bont Cycling's renowned power-transfer platform and pure anatomical design. The result is a product that utilizes more than 40 years of high-performance shoe manufacturing, feedback from the sport's very best athletes across every major discipline and blends it into one pair of seriously fast cycling shoes.

Every single element of the Crono MK2 has been built with aerodynamic gains in mind. From the revised toe box through to lace cover, heel cup, handmade 100% carbon fiber monocoque construction sole and even the heel guard, nothing has been left to chance. Finishing the package is our industry-leading 3.6mm stack height, proprietary thermo-moldable resin chassis and all while keeping the weight of each shoe under 300 grams.

Note: The Crono is built to order and ready to ship from time of order in 10-12 weeks.

    Fastest Shoes

    Posted by Koki Katakura on 25th Mar 2021

    I've been using the Crono Mk1 in non-UCI races. It was also a very fast shoe, However the shape was long and it could cause some resistance depending on the pedaling angle (the laces were good, though). After using the Mk2, I felt it was lighter, fit better, and had a larger allowable pedaling angle. The aero cover seals perfectly, and of course there is no need for heavy, hot shoe covers. I was able to win my age group in the 100km TT . Thank you very much.
