Rigid 29er/CX Flat Bars Bike

Quote

Cyclocross bike with flat handle bars?  Well, rider wanted a custom frame and fork with Cyclocross geometry, however, no drop bars.  The bike is going to be used half of the time on-road and half of the time off-road, primarily hardpacked dirt.  No long distance rides or bombing down steep mountain hillsides.  In addition, frame required to have lots of stand over, disc brakes and stand out from the crowd.

To achieve above objectives, we fabricated bent top tube and bent wishbone seat stays for extra stand over and desired aesthetics out of 0.035″ aircrcaft 4130 chromium-molybdenum steel alloy tubing.  Down tube, chain stays, head tube and braze-ons were supplied by True Temper, Columbus and Paragon Machine Works.  We prepared the tubes to run internal cable routing for cleaner lines.  As usual, Vicious Cycles did a great paint job on the frame and fork.

Frame was built with CX geometry.  We fabricated steel fork with 395 mm axle to crown measurement and 47mm rake with clearance to run WTB 40c Nano tires.  Currently, bike is equipped with Rolf Ralos XR 29er wheel set and Clement LAS 33mm tires.  Clement LAS tires allows speed on road and hardpacked dirt due to its file tread, and cornering on off-road due its small side lugs.

The bike’s drivetrain is a combination of Shimano CX50 (cyclocross) and Shimano Deore XT 10-speed (mtb) drivetrains.  Shimano CX50 includes crankset, front derailluer and two 46/36t chain rings.  Deore XT parts consist of 10 speed cassette, rear derailluer, shifters and disc hydraulic brakes.

Mission accomplished, and that’s why we do what we do…because we love it!  Thanks for checking in and enjoy the pictures.  Visit Chicagoathlete and Oldglorymtb for more coverage on this bike.

Stay tuned for more on our next Road/Gravel project.
