Kids Bikes – Jason’s 26er and Polina’s 24er

It’s time to post a little write up on two recent frames that I built for my kids. My son is 11 years old and my daughter is 9, and it was time to upgrade their rides so we can ride together on our local mtb/gravel trails. They both participated in the design of their bikes, including color selection of the frame, racks and frame bags. Thanks to Andrew from ATM Handmade Goods for designing the frame bags for their bikes.

My son got 26er mtb from our Hunchback line with long seat stays and bent top tube, and my daughter – 24er Troika with curvy frame lines. Both builds are set up with Shimano XT drivetrains, Velocity wheelsets, hydraulic disk brakes and powdercoat finish.

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.

Oleg’s Cyclocross Bike

Oleg wanted to start cycling after his shoulder injury that made him almost quit one of his favorite sports, volleyball.  He asked me to build him a custom bicycle frame to make sure that the bike will have correct fit considering his past injury.  However, Oleg wasn’t sure what type frame he needed.  So, we started a conversation.  After learning what type of riding he wants to do, I suggested to him to build a Cylclocross (CX) bicycle.  CX bike resembles a road bike, but it has larger clearances for tires that allows to ride off-road, and slightly different frame geometry with a slacker head tube/seat tube angles and fork’s longer axle-to-crown distance.  After taking Oleg’s body measurements and then applying them in Bike CAD Pro, we agreed on the design and I started to work on the project.

I used light-weight True Temper’s OX Platinum steel alloy tubing to build main triangle and Columbus Zona tubing for stays.  His bike has internal routing and equipped with Shimano’s mechanical disc breaks and Shimano CX drivetrain.  In addition, I built for him a custom CX steel fork with True Temper’s fork blades, steerer tube and Paragon dropouts.
