2023 Santa Cruz Megatower Carbon C GX AXS 29 Inch Mountain Bike Nickel

Season:2023

Brand:Santa Cruz

Code:58-22263-163-

The all-new 2023 Santa Cruz Megatower 3 Carbon C GX AXS is a downhill bike that goes everywhere. The Megatower’s big wheels, long travel, and tough carbon fibre chassis delivers the high-speed security traits of a downhill bike. Yet the relatively-steep seat tube angle and size-specific geo maintain the Mega’s mega pedaling ability—elevating its reputation as the perfect choice for big gravity rides and DH park laps.

Key Features:
  • Carbon C Frameset with Lifetime Warranty and Support
  • VPP Suspension with 170mm Front and 165mm Rear Travel
  • FOX 38 Float Performance Elite Fprk
  • RockShox Super Deluxe Select+ 230x62.5 Rear Shock
  • SRAM GX Eagle AXS Wireless 12-speed Drivetrain
  • SRAM Code RSC Hydraulic Disc Brakes with Avid Centerline 200mm Rotors
  • Santa Cruz 35 Carbon Bar
  • Burgtec Finishing Kit
  • RockShox Reverb Stealth/OneUp Dropper Post
  • Tubeless Wheels and Tyres

Glovebox

Place everything you need for a ride beneath the reassuringly high-quality latch and panel in the downtube, including your driving gloves. The Glovebox also comes with a Tool Wallet and Tube Purse, two refined pouches for keeping your essentials close to hand.

Steeper seat tube angle

The steep seat tube angle puts you in the right place to scale the steepest pitches to get to the wildest descents. Even better, it gets progressively steeper as the sizes get larger so everyone sits in the right spot.

165mm of VPP™ travel

A relatively-low leverage ratio not only makes setup easier but delivers a more damped, controlled feel across the travel range.165mm of travel comes standard, but if you choose to run a shock with a longer, 65mm stroke, you can bump it up to 170mm.

Proportional geo

The Megatower's chainstay length is matched to the frame size so every rider, no matter their height, gets the same balanced geometry.

Sizing Information

If you're on the cusp between the recommended height range of two sizes, the absolute best thing is to try to ride them both. At a minimum, check the stack/reach measurements on your current bike and compare it to the new model you are looking at to get an idea of a fit you are already comfortable with. If riding the bike is not an option, consider the following.


A larger size frame will be more stable, and will give you more room to move without upsetting the weight-balance of the bike. The larger size will put the front wheel further in front of you, which gives the feeling of security and conversely, it will require more significant body movements when you WANT to shift the weight-bias of the bike. Think hard about your riding style and how active/intuitive you want it to be vs stable and speedy. You'll need to work a bit harder to muscle the larger bike around.

Not all bodies at a given height are the same. If you have longer legs and a shorter torso than the average person your height, that may push you towards the smaller of the recommended sizes. If you're all torso and arms, most likely you'll want to size up.
