Steilacoom RCX

The Thoroughbred of Cyclocross has arrived and you get to ride it. The Diamondback Steilacoom RCX will take you across the finish line, but you have to remember to stop. The fully butted alloy frame with a formed top tube for easy portage and an integrated head tube is sturdy enough for the abuse that Cyclocross brings and the carbon fork saves weight without loosing performance. Throw in the FSA Gossamer Pro Cross cranks and the Shimano 105 10-speed components and this pony is ready to run with the best of them. If you’re ready to take your riding to the next level mount up on a Steilacoom RCX.

Highlights:

  • Diamondback CX fully butted 7005 alloy Competition Cyclocross geometry with a formed top tube and integrated head tube
  • Easton EC-70X carbon fork with alloy steerer
  • Shimano 105 derailleurs and dual control 10-speed shifters
  • FSA Gossamer PRO Cross cranks, 46/36t
  • 20 spoke front & 24 spoke rear wheels with sealed bearing hubs and Equation CX20 alloy rims
