Final Indian Pacific Wheel Race Curve Belgie Build

Here it is. The final build for my continent killing Curve for the Indian Pacific Wheel Race. After months of planning, building, testing, tinkering, hacking, bodging, and annoying my mechanic it’s finally done.

Words and Images - James Raison

It has been built with comfort, sustainability, and reliability in mind. It’s not the lightest or the fastest bike in the race but I’m confident it’ll see me to Sydney. I'm stoked with the final result.

I’d like to thank:

  • custom 13-36 SRAM cassette - cog sequence: 13, 14, 15, 16, 17, 19, 22, 25, 28, 32, 36.

Pete put together a specific cassette to give me usable gears for the flat, and a big range on the climbs. He individually chose cogs from multiple cassettes and made sure they would all work together. The shifting quality is fantastic and there's no issues with chain slack. He's a wizard.
