Why We Like The Santa Cruz Megatower C GX Eagle Transmission Reserve Mountain Bike

Whether we are looking for an all-out enduro race bike or a mini downhill bike, the Santa Cruz Megatower is an excellent choice when we need a ride that can do it all. With 165mm of VPP suspension, the Megatower lives to blast down the steepest of descents and is still efficient enough to climb back up and do it all over again. Size-specific chainstays ensure a balanced and stable platform for all frame sizes, and a new steeper seat tube angle, averaging 77.5 degrees, puts us in the perfect position to climb efficiently. The Megatower has a slack 63.8-degree head tube angle that instills loads of confidence when bombing downhill and keeps our front wheel out in front of us, which helps to keep us from feeling like we are going to go over the bars. Other notable features of the latest version of the Megatower include a Glovebox frame storage to keep all our ride essentials in the downtube of the frame and integrated downtube and chainstay protectors to keep our frame protected from rocks and chain slap. Additionally, a Shuttle guard on the top of the downtube allows us to through our bike in the back of our truck bed without worrying about scratching our frame, and the integrated rear shock fender keeps mud and dirt away from our shock for a cleaner suspension.

The GX Eagle Transmission AXS Reserve build of the Santa Cruz Megatower features quality components, an electronic drivetrain, and carbon wheels. The Carbon C frame is built to the same standards as Santa Cruz's premium Carbon CC frame but is slightly heavier to give us a reliable, stiff, lightweight frame. SRAM’s GX Eagle Transmission AXS electronic shifting provides the latest technology in the market today. It gives us flawless electronic shifting, a durable design, and the same huge gear range. Reserve's 30 HD carbon wheels and DT Swiss 370 hubs take this build sky high and give us a race-worthy wheelset that is durable, lightweight, and stiff. Another stand-out component is the RockShox Super Deluxe Select+ rear shock, which provides small bump sensitivity and keeps our back end locked down on the most technical of descents. A RockShox Zeb Select+ or Fox 38 Performance Elite, 170mm fork, handles the big hits in the front and has tons of adjustments so we can tune in to our riding style. Finally, Maxxis Assegai and DHRII tires supply loads of traction and bite on the rowdiest of descents, giving us the grip we need for high-level riding. When we are looking for an enduro race bike or just a bike that can handle days of huge descents and climbs at our local trails, the Santa Cruz Megatower is one of our top choices.

*Due to a high demand in the global supply chain and bike industry since the start of the pandemic, material weight and exact components are subject to change. We are working diligently to keep tech specs updated, and any adjustments will be of equal or better spec level. If you have any questions, reach out to a Gearhead by chatting online or calling 1-888-276-7130.
