Surly Instigator frame

Our review

Achingly heavy but anvil tough and long enough for all-round riding

While it’s no lightweight, weighing in at 3,280g (7.2lb), the Surly has the strength to finish whatever freeride madness you start.


The double-butted chromoly steel frame gets two big plate gussets behind the reinforced head tube, which can take a 100 to 130mm-travel fork.

The curved top tube gives ‘crown jewels’ clearance while ISCG, disc and removable cantilever brake mounts mean it’s ready for any braking setup. There are even two bottle mounts.

The massive right-angled CNC’d logo dropouts have secure, vertical slots and there’s an offside brake strut too, as well as space for up to 2.7in tyres.


The 23.6in top tube gives plenty of breathing space but there’s no missing the weight when you’re trying to get the bike moving, and you do need plenty of speed to translate into tricks once you’re off the ground.
