Steilacoom RCX Pro Disc

  • Diamondback Competition Alloy Cyclocross Frame
  • Easton EC-90XD fork for absolute stiffness and control up front
  • Mechanical disc brakes for enhanced stopping power
  • SRAM FORCE 10 speed drivetrain for maximum performance

At home in some of the wettest, muddiest, gnarliest terrain in the world, we know a thing or two about what it takes to make a mean cyclocross bike: one that sheds mud, ports easy and crushes any root or rock in its path. We understand that a light and stiff platform—via BB386—equates to more acceleration and control while out of the saddle. We also know that a flatter top tube for easy portage and the right geometry are essential to winning any race.

The 2014 Diamondback Steilacoom RCX Pro Disc is the perfect embodiment of everything Northwest. It’s well-equipped to tackle any single track, mud field, sand pit, staircase, hurdle or inclement weather between the starting gate and the finish line. At the core is the DBR CX Pro Spec Fully Butted 7005 Alloy Competition Cyclocross frame with formed top tube and an integrated headtube. The frame is light and durable which is something that we look for in a cross bike. The formed top tube features a flat bottom for easy portage over any hurdle.

Paired exclusively with the frame is the Easton EC-90XD carbon fork that’s exceptionally strong and stiff. With a tapered 1.5” carbon steerer set up for 160mm Avid disc brakes, it’s race-ready.

Component setup comes in proper with an impressive SRAM build. 10spd 1170 cassette, chain, Force derailleurs and Double Tap shifters—this is a dream bike. The SRAM S950 10spd Carbon Monocoque Arm, Cross Crankset with BB386 technology, offers a light weight and exceptionally stiff pedaling platform. A 46t – 36t double ring set gets you up to speed efficiently and the AVID BB7 Mechanical Disc Brakes are sure to provide the much needed braking power in all conditions.

Easton EA90-XD Disc rims are serious, super light cross rims laced to Easton EA90-XD hubs and wrapped with Michelin Cyclocross Mud 2 700×30c tires. Gluttons for punishment, these wheels will see you through to your finish line.

The cockpit, outfitted with FSA K-Force carbon handlebars, stem, seatpost, and topped off with the WTB Silverado saddle, is laden with quality. You can admit it, this bike is a stone cold stunner.

Whether you are looking for a true dedicated and capable cross bike for the season or are in search of the ultimate commuter, we’re not sure how you could do better than this.

The 2014 Steilacoom RCX Pro Disc looks as amazing as it rides, and comes in four sizes: 50cm, 53cm, 56cm, 59cm.
