Piotrek from Poland has recently built up a custom 2014 NS Bikes Soda Slope bike which features a rear derailleur and some trail components. With few tweaks he managed to make a really cool mix of slope and trailbike which allows him to move between his favorite spots with ease.
Thanks to short travel, short chainstay and wheelbase the bike is agile and light. Piotrek uses it to shred the local trails with his friends and hits the streets or a bike parks to practice his favourite tricks in the evenings.
