With average trail tyre weights creeping north of 900g, Bontrager’s refreshed XR4 Team Issue really stands out. At 760g for the 29x2.4in version, it’s light enough to put a noticeable lift in your climbing, acceleration and general agility. Siped and sloped blocks in a 61a centre compound with 50a shoulders mean it rolls fast but you can still get maximum use out of a 200mm rotor even in filthy winter conditions without it losing the plot. The ‘Inner Strength’ protective layer adds puncture protection but also seems to increase low-pressure stability, and while it’s a tight fit to get on, tubeless sealing is excellent. That all makes for a tyre that you can ride with the consistently connected control of a kilo enduro tyre and not far off the same expectations in terms of survivability, but will still put a significant injection of easy-rolling speed into your ride. It’s a sound price too.
