Old dog; new tricks.

It doesn't take a seasoned veteran to recognize the ride quality of titanium. After all, the material is one of the old dogs of boutique frame construction because its strength-to-weight ratio surpasses every other ferrous frame material (even exotics like scandium) but doesn't come at the expense of a harsh ride. That's more or less what the industry collectively refers to as "ride quality," and it's long defined what makes a desirable frame. In the Alchemy Eros Di2 Road Frameset, that ages-old ride quality is updated with Shimano Di2 compatibility, bringing the frame material of our dreams into contact with the drivetrains of the future. If titanium is the old dog on the block, the Di2 Eros proves that it's more than capable of learning a new trick.

Titanium recalls the halcyon days of cycling's past (while reminding us why discerning perfectionists still insist on it), but the ENVE carbon fork and tapered head tube are decidedly modern touches. Stiffening the front end is the name of the game here, and it helps preserve a gap while pushing through on fast, sweeping descents and while hammering out of the saddle on a climb in order to get that gap. The Eros is Alchemy's first bike, and even though it has its own carbon wonder bikes, Alchemy stands by the Ti Eros as "a sleek work of art" that will "outperform any bike made from any material." The art part is obvious (Those too-clean welds!), but the Eros is surprisingly sharp under hard efforts.

The frame's other dimensions also speak to racing rather than noodling. Its reach and drop are every bit as aggressive as a typical World Tour GC machine, and Alchemy puts that race-minded mien to good use as a showcase for titanium's eager, springy responsiveness. The combination of geometry and material recommends the Eros as a club racer that isn't (too) afraid of the prospect of clipping a pedal in the final corner.

That's not to say the Eros isn't only a hard-as-nails race slayer. It's got some elegant design features that improve aesthetics (the Alchemy dropouts) and contribute to a stiffer drivetrain and a softer ride (also the dropouts). Obviously, they're sexy, and only contribute to the Eros' insistence on love; however, they also let Alchemy stack the stays in your favor by beefing up the chainstays and lightening up the seatstays. That keeps all the pain going from pedals to road instead of road to saddle.

In a final touch of slick bling, Alchemy finishes the Eros with S-curve seat and chainstays. We've heard people argue that S stays increase comfort, but we're convinced that the design choice is purely aesthetic. The physics just don't support the comfort argument. Having said that, though, the sinuous stays strike a remarkable figure amid a sea of increasingly exaggerated "aero" monocoque frame designs. Don't get us wrong, we're all for drag reduction and boosting efficiency through creative tube profiles, but the Eros' shapely gams are reminiscent of the Old World artistry that defined mid-century frame building—less about engineering software and wind tunnels than pure touch.
