Supercross Envy RS7 – Evolution for Your Revolutions

Supercross BMX chief, Smilin Bill Ryan, is always at the drawing board, designing and refining the next generation of what thousands of BMXers will ride in the next couple years.

Of course, we don’t hear about the bulk of his test subjects, which are part of the “refine” stage of his long-standing iterative process.

You know what? We may-just see them on the track, and not even know what we’re looking at; they are painted and stickered-up to look like current SX product…but be sure that the next-gen stuff is being track-tested so it is race-ready when the time comes.

Enter the Supercross Envy RS7, the next model in the evolutionary-line of Envy BMX Race frames.

Here’s what Bill told us about the evolution baked-in to the new model, via a release:

For last three years, while we have been working to perfect carbon BMX racing technology with the ENVY BLK, we have been making notes, taking feedback and listening to what the riders around the world have been saying about the ENVY v5. All in the pursuit of building you the perfect aluminum BMX racing frame. The RS7 is the result of that work, and incorporates the following seven evolution points:

The RS7 Aluminum BMX Race Frame by Supercross BMXEvolution #1 – New, wider, flared seat masts for better BB support and faster launching. You will see that all seatmasts from the Micro to the Pro XXXL use a new forming tool, each size optimized for rider weight and strength to maximize launch.

Evolution #2 – Refined butting profiles to maximize strength and stiffness while minimizing weight. Every Supercross ENVY RS7 gets new triple-butted 7005 ULR tube sets that use our own proprietary molds and dies, specific for BMX Racing. This allows the frame to be stiffer, stronger and lighter.

Evolution #3 – 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, so we have 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. So while it looks like a larger heavier head tube, it is actually a stronger and lighter head tube.

The RS7 Aluminum BMX Race Frame by Supercross BMXEvolution #4 – New dropouts. The new Supercross ENVY RS7 dropouts, are still 3D-finished on the CNC, and are now cold forged to increase the strength and durability. And while we were spending the money on the new cold forging die, we also changed the shape, ever so slightly to allow your chain tensioner to work easier by maximizing the contact patch on the end of the dropout for ease of use.

Evolution #5- 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 and the new threads are rolled rather than cut to increase the life of your frame by ensuring the threads have a longer life.

Evolution #6 – Enhanced tubing diameters, a few tube sizes have changed in outer diameters to ensure that the frame stiffness is enhanced, without adding extra weight.

Evolution #7 – This may be the largest of the changes, on Pro size and larger frames, we have always used a “lug,” on the BB. The chainstays are welded into the BB lug and the lug is welded to the BB shell. By doing this, we maximize the weld area over having two tubes connect directly to the BB. Now on the ENVY RS7, we have taken that concept to the next level by having the chainstays meet the BB shell at the widest point possible, and have now completely boxed in the chainstays with .058 7005 sheet aluminum so the BB area is now a larger box that we accomplished with the old lug style, and increased your launch out of the gate where it is now nearing the performance of the carbon fiber ENVY BLK.

And with that you have the new Supercross ENVY RS7. Available in 18 sizes to fit every rider, and eight stock colors to fit every aesthetic.

And if one of the stock colors isn’t striking your fancy, we still do custom anodize and powdercoat finishes to enable you to make your Supercross ENVY RS7, your very-own.

Thanks for all that detail, Bill. There sure is a lot of tech baked into that puppy.
