Modular Mixed-wheel Madness
Powered by GG’s Modular Frame Platform, the MX Rally builds are our mixed-wheel option that combines progressive geometry with a playful spirit on our US-built bikes. Available on the Megatrail and Shred Dogg, 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.
Shred Dogg
As the most lively bike in GG’s lineup, the Shred Dogg turns the trail into your own personal playground. The 150mm fork takes the already capable ride and increases its downhill authority. Paired with the versatility of 130mm Trail Mode and 140mm Gravity Mode in the rear, it quickly evolves into a snappy and responsive pedaling platform, rendering it a true one bike quiver.
