Steilacoom RCX

  • Diamondback Competition Alloy Cyclocross Frame
  • DBCX Carbon fork for superior stiffness and control up front
  • Cantilever Brakes for the traditional crossbike setup
  • 10spd drivetrain to see you through your ride

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 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 RCX Fully Butted 7005 Alloy Competition Cyclocross frame with formed top tube and an integrated tapered 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 well with the frame is a DBCX Carbon fork that’s extraordinarily strong and stiff. With a carbon steerer and clearance enough for larger tires and fenders, this fork helps shave weight and provide strength up front for an exceptionally responsive ride.

Component pairing comes in hot and proper with a Shimano 105 build including cassette, chain, front and rear derailleur and dual control 10spd brake lever/shifters which are linked to Tektro CR710 canti’s to stop you on the drop of a dime. The FSA Gossamer PRO Cross crankset is standard as far as cross cranks are concerned and the BB386 technology offers a light weight and exceptionally stiff pedaling platform for the 46t & 36t double set.

New DB Equation CX23mm Wide Road cross rims are light and stiff and look amazing with white spokes laced to sealed cartridge bearing hubs. Kenda Small Block 8 700×32c tires create a grippy equation for any situation.

DBR drop bars and a DBR 3D forged stem offer precise and accurate steering while the DBR Performance Micro Adjust alloy Post (27.2mm) supports a WTB VALCON Race saddle for maximum comfort with race friendly size and weight in mind.

Whether you are looking for a true dedicated and capable cross bike for the season or are simply looking for an adept and stable commuter, look no further.

The 2014 Steilacoom RCX is blacked out and comes in four sizes: 50cm, 53cm, 56cm, 59cm.
