マルセル・キッテルさんのインスタグラム動画 - (マルセル・キッテルInstagram)「My first race ever was a mountainbike race in 2001 and I rode with a triple chainring. Fast forward to today and you can ride one chain ring with the power of two with @classified.cc. Incredible how bike tech advanced in those years and I’m really proud to be part of that journey with Classified. 💪🏼 #shiftyourthinking #classifiedmtb #rideclassified #mtb #mountainbike」4月5日 2時13分
