The wheelset consists of Alex alloy double-wall 48-hole rims, DB Slasher high-flange alloy hubs, and 146 stainless spokes, wrapped in DB freestyle 20x1.95” tyres front and rear. Comfort comes via a DB padded freestyle seat with a chromoly micro-adjust seatpost (25.4mm), while extras include an SST Ory 1-1/8” rotor and stainless steel oversized threadless pegs.
