10 years ago we created the first BMX Superframe, the Supercross S7. It was developed to be the Ultimate BMX Race frame, and it proved to be just that. Ultra-light, incredibly responsive, super strong, and pretty expensive. But it displayed that you can build a sub 3lb Aluminum race frame that will last for multiple seasons. This Superframe laid the framework for our ENVY line of race frames. 10 years later, we introduce you to the latest addition to the Envy line, the Envy RS7!


The Supercross ENVY RS7 utilizes our special blend of 7005 ULR Ultra Light triple-butted custom-shaped tubing that is a direct result of working with Easton® Tubesets for over a decade. Why 7005 Aluminum, you ask? 7005 has higher strength and yield than 6061 when properly aged and heat treated. Kind of a Superhero of Aluminum. Sound too good to be true? We thought so too, but after a decade of real-world testing, we can tell you that this frame is the real deal. Ultra stiff, yet incredibly light.


Now you Supercross fans will know that the 7005 ULR tubing has been used on all our ENVY Aluminum race frames for the last 10 years, so what makes the RS7 new? 

The RS7 is the next evolution of the original ENVY frame. So it shares many of the previous improvements while bringing a few of its own to the party.

Here’s a running list of the improvements made to the Envy line over the years, making the RS7 the best Aluminum Supercross frame to date!

For the Fastback specifically, we removed the V-brake post. This sleek rear-end aesthetic is actually how this RS7 variant got its name. We also beefed up the rear dropouts with more material to help handle the increased stopping power of disc brakes.



Other improvements that apply to all ENVY RS7 frames include:

Wider flared Seat masts for better BB support and power transfer resulting in faster launching. All seat masts from the Micro to the Pro XXXL are of a new forming tool. Each size is optimized for rider weight and strength to maximize gate start launch. 


Refined butting profiles to maximize strength and stiffness while minimizing weight. Every Supercross ENVY RS7 gets new triple-butted 7005 ULR tube sets that are our own custom molds and designed specifically for BMX Racing. This allows the frame to be stiffer, stronger, and lighter across various areas of the frame. 

Refined head tube shaping. This may seem like we are being overly critical, but we listened, and during travel, a few people stated they had problems with the airlines denting the head tubes on their ENVY's. We developed a new head tube that more closely mimics the shape of the ENVY BLK head tube and has thicker bearing race seats and walls. It may look like a larger, heavier head tube, but it’s a heck of a lot stronger and lighter than other head tubes. The RS7 provides the stiffest front end across our previous aluminum models. 


The ENVY RS7 also received updated dropouts. They’re still 3D CNC'd with backside releavement to reduce weight. the dropouts are now cold-forged to increase their strength and durability. While we were spending the money on the new cold forging die, we also changed the shape slightly to allow your chain tensioner to work easier by maximizing the contact patch on the end of the dropout for ease of use.


New Cold Forged Bottom Bracket Shells with cold rolled threads. We have always machined our BB threads after the final heat-treating process to ensure the truest and longest-lasting threads. But now we are using a new cold-forged BB shell with a tighter grain density to better handle the extra power you are putting out. The new threads are rolled rather than cut to increase the life of your frame and ensure the threads have a longer life.


Are you getting the idea yet? We take the Supercross frames you love and continue to refine them for an even better ride and longer-lasting frame over every generation!


This may be the largest of the changes. On Pro size and larger frames, we have always had the BB lug, where the chain stays are welded into the BB lug, and the Lug welded to the BB shell. By doing this, we maximized the weld area vs. having two tubes connect to the BB. Now on the ENVY RS7, we have taken that concept over the edge having the chainstays meet the BB shell at the widest point possible, leaving us with completely boxed-in chainstays with 7005 sheet aluminum. The BB area is now a larger box than what we accomplished with the old lug style and increases your launch out of the gate, where it is now nearing the performance of the carbon fiber ENVY BLK. The RS7 is the stiffest aluminum Supercross frame to date!


With that, you have the new Supercross ENVY RS7 Fastback. Available in 5 20" Pro sizes different sizes to fit all sizes of riders , 3 24" sizes Pro, XL and XXL and a Pro 26" Cruiser and 8 stock colors ( Pearl Black, Pearl White, Gun Metal Grey, Racing Red, Metallic Blue,  Hi Vis Yellow,  Matte Black, and Mirror Polished ) to make sure it fits your style. And if one of the 8 stock colors isn't what you want, we still do custom anodize and powdercoat to enable you to make your ENVY RS7 truly yours.
