The Sonder Cortex bike impresses with its precise handling and stable frame, powering through rough terrain with nimble ease and reliable componentry.
We handed the Cortex over to Guy Kesteven for some real trail testing.
Cortex is a light, well-shaped frame that balances instant familiarity with extra confidence on faster, rowdier trails. Add an easy to set up fork, decent stop, go and finishing kit rolling on sturdy wheels with a properly surefooted front tyre and you’ve got a great package for the price.
