Two bikes I would have back tomorrow;
Yeti ASR5C with SRAM xx1 and a Lefty; Hope brakes, Mavic wheels. Light fast and a blast.
Original Ibis Mojo with a Rohloff hub on the back. Not the best weight distribution but never faltered for 5 yrs. +38 degrees Celsius to -35C (Edmonton, Canada). 5 oil changes and one chain the only drivetrain maintenance. And Ibis were great - asked them about grinding a bit of carbon away to allow clearance for the Rohloff and they said the 0.5mm I needed was fine by them!
