Karl Platt has been part of the SIGMA family for 15 years. “As a brand ambassador, I want to actively promote the SIGMA brand,” says Platt. “I have done a lot of cycling in my day and have lots of ideas for how we can improve biking for pros and amateurs. I am looking forward to integrating those ideas into new SIGMA products.”

Karl about the rox 11.1 evo

“The ROX 11.1 EVO combined with the SIGMA RIDE APP makes handling a lot easier, so I can plan whole tours or just the return leg! Its battery lasts for a very long time, so I don’t have to worry when I go for a long ride.”
