SQUIRE Challenger 260 lock, £19.99, www.squirelocks.co.uk

Squire’s Challenger 260 is a good all-round D-lock rated Bronze on the Sold Secure scale, providing decent security for your pub steed or runaround if you don’t want to spend three times more on a higher-rated lock. The 12mm steel shackle has 260mm of clearance, so there’s plenty of room to attach wheel and frame to something solid, and the screw-on bracket held the Challenger firmly in place while riding. Will see 
off opportunists and only be beaten by the best-equipped criminals.
