Modular Mixed-wheel Madness
Powered by GG’s Modular Frame Platform, the MX Rally build is our mixed-wheel option that combines progressive geometry with a playful spirit on our US-built bikes. Available on the Megatrail, the MX Rally builds deliver another layer of customization, allowing riders to experience the stability of a 29er with the maneuverability of a 27.5.
Megatrail
Designed to bookend GG’s most aggressive geometries, the Megatrail modular platform is the perfect fit for a mixed-wheel build. The 165mm Gravity Mode is the “lowest and slackest” configuration from GG. For trail and technical riding, the 155mm Trail Mode adds a slightly higher and steeper option.
