Maybe you recall a man by the name Christopher Robin that I’d posted about before? During the long winter months, he spends his free time making bicycles in what most would consider sub-standard conditions using implemented tools and techniques. For his latest endeavor, he decided to construct a replica of Graham Obree‘s hour-record breaking track bike. In a word, the outcome is immaculate!
You have to check out the rest of the photos and a video below. It’s insane!
Here’s the text translated:
“I don’t know who is more foolish.
The fool or the one following the fool…
I suppose i am a bit of a fool.
I’ve spent nine months building this thing, and here i am in a car heading up to Falun to take it for a ride.
So yeah, I guess that probably makes me a bit of a fool…”
Christopher was kind enough to send a full parts break-down as well:
Frame: Carbon fibre with balsa wood core. Intergrated saddle (San Marco Roll´s modell) and seatpost. 70mm spacing between dropouts
Fork/ Handlebar: Carbon fibre mono fork with intergrated stem and handlebar. Handlebar width 30cm (at the widest)
Headset: Nylon glide bearings 24mm wide
Front wheel: Specialized tri spoke with modified hub
Rear wheel: Specialized tri spoke with casette tread, the cog is mounted backwards to get the chain line as narrow as possible. No lockring needed.
Bottombracket: Shimano Tiagra customized to 40mm width
Crankarms: Shimano Tiagra 170mm reshaped for a narrower q-factor
Pedals: Intergrated pedalaxel on Shimano shoes
Chainring: Custom made alloy 50t
Chainring bults: Dia comp alloy
Cog: Shimano Dura ace 13t 1 1/8 (now I have a 12t)
Chain: Izumi NJS 1 1/8

This is seriously amazing! Thanks for sharing Christopher!
