I’m after a hardtail for quick local muddy winter rides , I fancied something like the sonder but am I barking up the wrong tree
Get a Sonder and some cheap 29er wheels with mud tyres. Bigger tyres in sloppy mud will act like a boat – your weight won’t be enough to displace the slop under the tyre to grip the harder stuff underneath, whereas a skinner tyre with less air and a smaller contact patch will cut through. When things start to dry out switch back and enjoy the benefits of masses of traction and float.
