Steilacoom RCX Disc Complete Bike

Diamondback Bicycles knows a thing or two about wet, muddy, gnarled terrain — the exact breeding ground for mean cyclocross races. Born in the Pacific Northwest, Diamondback's Steilacoom RCX Disc sheds mud, transports easily, and crushes any rock or root in its path. And the best part is that you'll rock a cyclocross-specific bike that won't break the bank.

Its frame was built with fully-butted 6061-T6 Alloy. What's a fully-butted frame? Well, when tubes are joined in this manner, rather than featuring a continuous wall thickness, the ends of the tubes are given varying widths, which in turn, creates a stronger frame. And although it sounds counterintuitive to remove metal to increase strength, frames usually fail at the joints, and butted construction decreases the stress concentration factor in the joints. Less material equals less stress, which equates to more strength. The Steilacoom frame includes a formed top tube with a flat bottom that's designed for comfortable carries. Cables are routed on top in order to prevent them from digging into your shoulder. Meanwhile, the BB386 bottom bracket creates a light, yet stiff platform for acceleration.

Designed specifically for the Steilacoom, the fork is also designed to withstand the rigors of cyclocross' mud fields, staircases, and barriers. It features carbon legs and a tapered carbon steerer tube. The steerer provides enough clearance for larger tires and even fenders, in case you decide that you want to join a group ride or two. The carbon fork helps to shave weight while increasing strength and is exceptionally responsive.

The Steilacoom RCX is no slacker in the component department either. Shimano 105 10-speed is used for the derailleurs and shifters. Drivetrain duties are driven by a FSA 46/36t Gossamer Pro crankset with a BB386 for an exceptionally stiff pedaling platform. Rounding out the back is a 12-27t Shimano CS-4600 Tiagra cassette and a Shimano 105 chain. TRP Spyre Dual Piston Mechanical disc brakes ensure that you'll stop no matter what the conditions, especially with the 160mm front and 140mm rear rotors. Meanwhile, the cockpit is comprised of Diamondback's DBR handlebars, stem, and seatpost, with a WTB Valcon Race saddle topping off the post. And lastly, the wheelset features Diamondback's new DB Equation CX wheels that are cased in Kenda Small Block 8 700c x 32mm tires.

The Diamondback Steilacoom RCX Disc is available in the color Black and in the sizes 50cm, 53cm, 56cm, and 59cm.
