Courage to use colour - we like that. With the Black Sin, Radon not only opts for large wheels but also for striking colours. The 8.0 model marks the entry into the 29er range with a carbon frame (1070 g) and offers an impressive spec for the money. The Formula brakes have external lever adjustment and you can rely on Shimano's XT with triple cranks. The bike lacks nothing, because instead of lockout on the handlebars, we prefer the Fox fork with triple adjustment (CTD). A practical development. The bike moves forwards, rolls fast and whizzes nimbly over the trails. It is superior to 26er bikes in terms of smoothness, even if it is hard and not very comfortable due to the system - a hardtail. Conclusion: If you spend more money on a carbon racer, it's your own fault.
