Ok, let's be honest: Gravel bikes are a true style statement! That's why we designed the ACID GRAVEL – not just any luggage carrier, it's our super-stylish take on a functional piece of kit. The superlative in reliable load-carrying capability, its minimalist design means you'll hardly notice it's there. Functional understatement for all CUBE Nuroad, CUBE Travel Sport and CUBE SL road bikes from model year 2021 onwards.
