Evil Offering 151 Frame Only (V4) - DELTA System 151mm Trail/Enduro Chassis Carbon 29er Chassis - Internal Storage
The Evil Offering 151 Frame Only provides the blank canvas for building your dream aggressive Trail or Enduro 29ER. This is the latest version (V4) of the celebrated Offering platform, boasting a highly efficient 151mm of rear wheel travel controlled by the acclaimed, progressive DELTA System suspension linkage.
Constructed from a completely redesigned Unidirectional Carbon Fibre chassis, the frame maintains exceptional stiffness and durability while integrating modern, rider-friendly features. Crucially, the down tube now houses a secure internal storage compartment, allowing you to stow essential trail tools and snacks cleanly within the frame.
The geometry is modern and highly adaptable. The frame features a slack Head Tube Angle (HA), a steep 79.2-degree effective Seat Tube Angle (STA) for powerful climbing, and short 435mm chainstays for a nimble feel. The Rip Chip is integrated into the DELTA linkage, enabling quick, on-trail geometry adjustment between High and Low settings to perfectly dial in the handling for your chosen terrain and fork length.
The frame accepts a 205 x 60mm Trunnion mount shock (not included) and is ready for forks ranging from 160mm to 170mm travel.
With its threaded BSA bottom bracket and standard Boost 148mm spacing, the Offering 151 is designed for easy assembly and long-term maintenance.
