Fat Bike, Impaler
This bike was built with twin top tube, custom segmented fork, and custom rear and front racks. Impaler is a theme bike that was exhibited at Philly Bike Expo in November last year. The frame’s front rack was shaped like a spear, to give the entire bike the look of Vlad the Impaler.
The Impaler bike was built as an all terrain type of fat-bike and this particular build has the following:
•curved twin top tube/stays and seat tube
•short 16.7″ chain stays
•177/12mm trough axle dropouts
•custom steel segmented 142/15mm through axle fork
•Velocity Dually rims with I9 hubs and 4.0 Veerubber Mission tires, tubeless
•Shimano XT 11speed/Raceface 30t ring drivetrain and cockpit components
•Powder coat finish
•Custom frame bag made by ATM Handmade Goods.
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.
It’s been more than a month since Gran Fondo New Jersey race and here are few pictures from the 107 mile race on the Troika Road frame. It was a 7.5 hours unforgettable riding experience starting in Morristown, NJ going to the Delaware River and back with over 9,000 feet elevation… my longest ride so far!
Hope you enjoyed your summer and had your good share of rides and fun. I’ve been working on the road frame and fork that I wanted to use in the Gran Fondo NJ race, which is coming up next Sunday. The race starts in Morristown with an amazing route to the Delaware River and back. It covers 107 miles and has four challenging timed hill climbs with total climbing over 9,100 feet.
The frame and fork are done and bike is completely set up. I had a twenty mile ride on it and the ride felt perfect. I used BiceCad Fit advisor to design this frame. This application allows one to enter rider’s dimensions, which in turn gives an optimal bike size for the rider. So, every bike is different and is specific for a rider when I build the frame.
I utilized a True Temper, OX Platinum steel tubing for the construction of the front triangle. This alloy is double butted with tube wall thickness of 0.7-0.4-0.7mm. In addition, this is an air-hardening steel alloy, meaning it does not lose its strength after applying high heat during TIG welding.
The bike has a lively ride that offers a balance between road feel, stiffness and comfort. Double-butted tubing dampens some road vibration and offers good feel for the road surface below. This quality is what leads many riders to experience the sense that a steel bicycle is an extension of the rider.
The frame is TIG welded and has internal routing for shift cables and breaks. I built a segmented fork with 1″ steerer tube. The frame is powder coated and has custom Jen Green’s head badge. I installed a Sram Apex group set with white finish and ten speed drivetrain.
Check out some pictures of the bike and stay tuned for an update on the new Road Disc/Di2 project for my old friend, Dr. Eduard Burt, DC. He is an avid cyclist and a great health practitioner. Take a look at his blog for cyclists on how to lower neck and back pain here.
