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 pedaling ability—elevating its reputation as the perfect choice for big gravity rides and DH park laps.

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.
The Megatower is available in sizes small - extra extra large (S-XXL).
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.
FAQ's
Can I mount a chainguide on this bike?
Yes, this bike is equipped with ISCG-05 tabs for easy chainguide mounting. Our bikes come standard with the OneUp Bashguide V2 or the e13 TRS, but most guides that follow the ISCG-05 standard should fit.
Can I convert the Megatower to 27.5" MX wheels?
No, the Megatower is built exclusively for 29" wheels and tires front and rear. The geometry is not setup for any 27.5" front or rear conversions.
Where'd the chainstay length adjuster go?
Where the Megatower 1 had a single chainstay length that was user-adjustable, The new MT2 now has size specific chainstay lengths to optimize the geometry across the size range with no fuss or extra parts.
Can I run a dual-crown fork?
Nope, the Megatower is not designed for use with a dual-crown fork.
What is the recommended fork?
Our geometry is based off of a 170mm fork with a 42 or 44mm offset. We wouldn't recommend less travel than that, as the BB will get a bit low. Up to 180mm is fine if that's your preference.
What kind of headset does this bike use?
This bike uses integrated headset cups. The upper up is 41mm and the lower cup is 52mm. The SHIS name is IS 41/28.6 IS 52/40.For Chris King this is a DropSet.
Should I ride in the High or Low shock flip-chip setting?
You should definitely try both, but we typically recommend starting in High. This will make the bike more agile and easy to get used to. If your terrain is quite steep, give Low a try. This setting lowers the BB by 3.5mm, slackens the head angle by 0.3 degrees, and generally just biases your weight a little further back. The leverage curve of the suspension changes slightly as well: it's more progressive. The geometry changes combined with the slight suspension change will make you feel like you're sat further down in the bike. Great for steep gnar, not as good for flatter corners. It's easy to change, so experiment!
I want to change my rear shock. Any limitations?
The Megatower was built to be compatible with all shocks on the market, both coil & air. We haven't tried some of the smaller obscure brands, but it fits anything from Fox and Rockshox. The correct size is 230x62.5 with 8x30 hardware front and rear.
Can I make this frame have more travel?
If you change the rear shock to a 65mm stroke length (stock is 62.5mm) you do get more travel - 170mm. We felt 165mm was the best option to make the Megatower balance going up down and up again but if you want more, that's how.
What size tire will fit?
The Megatower is designed for 29" x 2.5" max
Does the Megatower use the SRAM Universal Derailleur Hanger (UDH)?
The frame is UDH-compatible, but comes with our own machined aluminum hanger. You can replace it with another Santa Cruz hanger or a SRAM UDH.
Should I get the coil shock or the air shock?
There is a difference in feel between the two, but neither is better than the other- just different. The air shock is more progressive than the coil, which allows for a slightly softer setup without worrying about bottoming-out. This will generally offer a smoother ride, but one that can still be ridden very aggressively and not struggle. The suspension will also have a "poppier" and more playful ride, as the air shock will try to get you out of the deep part of travel.
The coil has a slightly more linear feel/ less bottom-out resistance, which encourages a firmer overall setup. This offers the maximum mid-stroke support for berms/park riding/ pushing into turns. If you like a firmer feel, you will probably prefer the coil. If you set the air shock up to offer a similar feel in the mid-stroke, you may struggle to achieve full travel.
These aren't huge differences, but they are enough that we wanted to offer both. Obviously, the air shock offers the advantages of being lighter and easier to tune, so this will be the right choice for the majority of riders.
What can I store in the glovebox?
The Megatower comes with two bags - a tube purse and a tool wallet. You should be able to fit a superlight tube, a small pump, tire lever, and misc odds and ends in these two bags. For more information, take a look at our Glovebox Tech Page.
