Specialized Butcher Control is a relatively cheap all-rounder, but you wouldn't know it from riding it.
While most cheaper tyres use slippery plastic compounds, the Butcher's 50a duro mix is tacky enough for ample traction even on typically lethal surfaces such as green rocks and roots.
It's fully tubeless-ready too, which is a real coup at £30, and helps give a smooth and supple ride that's a match for more expensive tyres in terms of moulding to mixed rocky, rooty terrain.
The 420/D1 casing is designed to be more cut/wear resistant than a standard cross-country carcass, but it's not as supportive as a fully armoured one. It's skinny too, so don't go low on pressure in rocky terrain. Performance is excellent for the price.
