This is a single speed fully customized Gary Fisher Mullet. The only stock part on the bike is the crank. Everything else has been upgraded, including: Rockshox Argyle fork w/ 20mm Thru-axle, Bontrager King Earl wheelset, SS conversion kit, Shimano saint quad-piston hydraulic disc brake, 12mm thru-axle in the rear, Kenda K-Rad tires, Holzfeller Bars, Lock-on Oury Grips, Chris King Headset. It's a professional level bike for dirt jump, single track, freestyle, or even urban freestyle. It's very versatile and beefy. All of the upgrades alone are worth at least $1500, so this is a sweet deal. I don't ride much anymore as school has dominated my life. Contact me with any questions, I'm happy to answer.
