A new smaller rear cog combined with a smaller chainring reduces weight while maintaining climbing-friendly gear ratios
Adjustable rear dropouts enable precise chain tension and wheelbase tuning
THRU-TUBE seat tube design increases fit range to accommodate growing riders
Sealed cartridge bearings throughout for superior durability
High-volume Kenda Booster tires for improved traction and ride comfort
