Factor VAM Disc Rolling Chassis

Factor offers the superlight VAM Disc frameset as a Rolling Chassis, which not only includes the Black Inc Carbon Integrated Bar/Stem system and Black Inc Carbon Seatpost, but also the 1475 gram Black Inc Thirty Disc carbon tubeless ready wheelset.

The research and development that brought the world the Factor O2 frameset design provided Factor's engineers with huge amounts of data and knowledge as they built a fantastic riding, sub 800 gram road race frameset that sacrificed nothing in the pursuit of wins and personal bests. So after a few years of incredible success for this smaller frame company, what did Factor do? How about going to back to the O2 drawing board, albeit with a head start, and create the VAM Disc frameset, with a new carbon production process, some different material technology, and a commitment to maintaining or improving the O2 across the board.

Enter the sub 700 gram VAM (Velocita Ascensionale Media- average ascent velocity), frameset. Unlike many superlight road framesets, the VAM was not only built to climb, but to dominate descents and ride like a dream. The cockpit set-up is pro-style low friendly with a new headtube and headset top cap/spacer system. Overall the geometry is incredibly close the O2, with the same Stack and Reach. Current O2 riders who desire the lightest version will find it all very familiar, aside from the approximately 10% reduction in frame weight. So what is different? VAM is manufactured with a completely new method of carbon compaction. Pressurization greater than normal allows the engineers to wring excessive resin from the various base carbon materials, therefore making the carbon stronger, lighter and more efficient.

As with all Factor frames, the VAM was optimized with a strategic layup of mixed modulus carbon that helps further define and augment VAM'S decisive handling and riding characteristics. The materials list is impressive as well with Factor adding TeXtreme®, Nippon Graphite pitch fiber, and boron fiber to their secret sauce. The combination of fiber and materials used in with the new compaction process combine to deliver the lateral and torsional stiffness required to keep the frame efficient and a perfect platform for power transfer, while resulting in a solid and sure feel when descending or sprinting. Boron fiber is not new to cycling, as several frame manufacturers have used in superlight frames, but Factor has used it primarily to reduce weight while maintaining proper lateral stiffness in the seattube, with no compromise in ride quality.

The 54cm disc model bare frame weighs in at 690 grams. Let that absorb for a second. The superlight platform is a perfect choice for building a complete bike that destroys the UCI minimum weight limit, yet can still be ridden in all conditions and situations. Even the tapered fork received the VAM treatment, looking slightly wasted next to the standard O2 Disc model. The essentially nude carbon, with the slight touches of a sharp red, looks raw, clean and light. This VAM Disc frameset comes as the Rolling Chassis version, so the Black Inc Carbon seatpost, and Integrated Carbon stem/bar are part of the package, along with the Ceramic Speed headset and bottom bracket and pretty awesome set of wheels. The internal routing system is compatible and friendly with both mechanical and electronic shifting systems. With the Rolling Chassis you receive the impressively fast and light Black Inc Thirty Disc Wheelset with it's 21mm internal, 30mm external tubeless compatible disc rim design, CeramicSpeed bearings, and 12mm thru-axle hubset- all at just 1460 grams. You'll need a braze-on front derailleur, and besides your choice of components, pretty much everything else is included, even an out front style 1/4 turn mount for the Black Inc handlebar, and bar tape. Finally, the disc frameset features Flat Mount hydraulic brake caliper interfaces, as well as 12/100mm front and 12/142mm rear bolt-on thru-axles, which are provided.

We'll leave the key closing words to Rob Gitelis, owner of Factor: “Historically speaking, bike brands have always struggled with the balance between maximizing profit versus developing the best bike possible. After over 20 years in the industry, I decided to throw out the rules and challenge Factor with one simple goal: to develop the absolute best bike in the world. With the VAM I truly believe we have achieved this goal, and I can’t wait for our customers to experience this bike.”

And frankly, neither can we. Whether you want to build your VAM with Shimano Dura-Ace Di2, SRAM Red AXS 12, or Campagnolo Super Record 12, Excel Sports is here for you.
