My bikes tend to evolve and bits get moved from old frames to new etc, rather than buying complete new bikes.
But of particular note are;
My Inbred with Pace RC31 forks, it made me relearn how to choose lines and just how much difference suspension and fat tyres can make.
Turner Flux (TNT). It's meant to be an XC bike but on my first ever trip to Whistler it seemed more than happy in the Bike Park. Sure I wrecked my RS Reba forks in the process, but it's a frame that will take literally anything you throw at it as long as you can hang on. It really opened my mind to new riding possibilities beyond standard UK XC.
2008 Orange Five with Fox Van 32 QR15 forks and nice fat 2.35" Kenda tyres. This bike in this setup has blown me away, it just eats up any terrain and over the past couple of years the rate of progression in my riding has been huge. It's the ultimate skill compensator….until I find one with even more travel that is still rideable up hill 🙂
