If you’re serious about riding through the winter, or racing in wet and slippery conditions then a pair of dedicated mud spikes will help enormously. There’s only so far you can push an ‘all-conditions’ tyre designs regardless of tyre pressure settings.
Here in the UK we can be running on sodden and greasy tracks from October through to March, and even beyond. A pair of mud/wet tyres are essential for staying upright in all but the most parched conditions.
Specialized have been in the tyre business for over forty years and as such offer a full range of both gravity and trail tyres at realistic prices for the privateer racer. They don’t cut corners either, with plenty of tech and development going into their rubber.
