Upcoming: Specialized demo after 2 years test.


We would like to show you and prove, that even though bike industry is so technologically advanced, the bike doesn’t have to have Carbon frame with 27.5 inch wheels, to look and ride well.

The test will be released soon.

The bike which you can see on photos below, is based on well known frame specialised demo, m-size in original and underrated paint job from 2013. This bike has gone through many modifications, which are so well composed together, you cannot notice it at first moment. The thing that gets to your eyes as non-stock part are tubeless Crank Brothers Opium DH wheels. The biggest modifications were made in suspension. Rock Shox boxxer has been updated with Charger damper which is a completely new damping system for boxer. The biggest drawback of Charger is the price: more than 1400 pln in Poland. The rear shock has been updated with push internal dampers which are about 1000 pln in Poland. The brakes were also changed to Avid Code R with cloud 203 and 180 rotors.


Owner of the bike is 25 years Old Artur Simon (Kubica), a member of BartBass GoodBike DH Team, who has few successes in career. He is a good representative of Elite category in polish downhill. Arthur is racing for 3 years in professional category, however he has been ridding downhill since 2008.
