Dedacciai Strada's latest Ran frame puts the company's usual emphasis on sculpted styling on the backburner, in favor of a more engineering-centric design.

Though perhaps not as curvaceous or striking as other bikes in the range, such as the Temerario and Super Scuro, it's hard to argue with the Ran's claimed 810g frame weight.

Such a single-minded focus on maximizing material efficiency gives the Ran a familiar profile. This includes plenty of round-to-rectangular cross-sections, big chain stays, slim and compact seat stays and a tapered front end – all notably devoid of superfluous sculpting that might lend more style but inevitably add weight.

Along those same lines, Dedacciai Strada has given the Ran a tapered front end but in a slightly smaller 1 1/8in to 1 1/4in dimension that lends a smoother ride than the more common 1 1/2in lower steerer diameter.

Plus, the oversized bottom bracket is built around the press-fit 30 standard that allows for an ultralight, bare carbon shell. Up top is a slim 27.2mm seatpost that affords a smaller and lighter seat tube but also more comfort out back.

Dedacciai Strada has wisely built the Ran to work with virtually any current drivetrain, with battery mounts for both Shimano Di2 and Campagnolo EPS systems. It also has removable ports for internal wire routing, and bolt-on guides for externally running conventional cables.

Dedacciai Strada will offer the Ran in five sizes when it becomes available toward the latter part of this calendar year. Pricing is estimated at around €2,290 / US$2,600 for the frame, matching 325g all-carbon fork and integrated headset.
