A downhill bike that goes everywhere
Seriously. The Megatower’s big wheels, long travel, and tough carbon fiber 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 pedalling ability—elevating its reputation as the perfect choice for big gravity rides and DH park laps.
GloveboxPlace 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. |

Full carbon C and CC frame optionsWhile both versions of our carbon frames are made in our own factory, are just as strong and stiff as one another, and have a lifetime warranty, there are a couple of differences between the two. CC frames use the very best materials and production processes available, while our C frames add on a little more weight for a little less $. |
|
Steeper seat tube angleThe 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. |
|
170mm of VPP™ travelA relatively-low leverage ratio not only makes setup easier but delivers a more damped, controlled feel across the travel range. |
|
Coil and water compatibilityEven with a lower-link flip chip and the option to run large-body shocks, like a coil, you’re still able to fit a water bottle inside the front triangle. |
|
Sensitivity and constant tractionThe Megatower's low leverage ratio to provide a more damped, controlled feel at speed. Lower anti-squat reduces pedal induced firmness and provides excellent square edge bump absorption, which gives you a greater margin for error when taking blind risks on wild trails. |
|
Details matterThe frame details are completed with a neat mud flap that protects the rear shock, a rubberized downtube protector that shrugs off strikes, and tidy cable routing within the frame and swingarm. |
|
Proportional geoThe Megatower's chainstay length is matched to the frame size so every rider, no matter their height, gets the same balanced geometry. |
|
Full size rangeFrom size small to XXL, no one misses out on the Megatower. |

Frame Sizing
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.
Personal Preference - 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.
Body Dimension - 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.
