A strong value trail bike suited to winch and plummet riding that gets better as trails get harder
Great geometry
Good tyres
Short travel dropper
Small rotors hold it back

Launched in August the Sonder Signal ST is essentially a steel version of their existing Signal Ti model - that's Ti = titanium of course. You can check out Andi's Signal Ti review here. In that review Andi's large test bike had a reach of 457mm. That was over a year ago now of course and things have lengthened ever so slightly to the current reach of 465mm on size large. On the size medium I have been riding that reach is 440mm. So it's not just the frame material that has changed over the last year or so.
