The HC1 is a very limited colorway release to commemorate Harry Clarke's outstanding 2024 season including a victory at the World Skate Games and the securing of the WDSC World Championship title.  Harry brought Rogue it's first world title in 2019 on the original Gold Slalom trucks and in 2024 he was nearly un-beatable in his pursuit to re-take the crown riding ZM1s.    
 
HC1s ship standard with Harry's personal bushing setup which differs slightly from the stock ZM1 offering by changing the front 73a Barrel for a 78a Cone, and the rear 95a barrel for a 93a version.  All other truck specs are the same as the regular production ZM1.
