OnGuard RockSolid 8950 review: finally, the bike lock to stop opportunistic thefts?

Matt IschtBarnard Future
Our best overall angle grinder resistant lock the onguard rocksoild resting against a bike rack.

The OnGuard RockSolid 8580 is a Sold Secure Diamond-rated lock that is claimed to resist angle grinders making it ideal, in theory at least, for securing high-end road, gravel and electric bikes.

OnGuard may not be the most recognisable brand in bike locks, but it operates as a subsidiary of Magnum Locks, a large industrial firm that’s focused solely on security. This relationship gives OnGuard access to a broad range of expertise and manufacturing techniques. Leveraging this specialisation and advanced knowledge, OnGuard has developed what it says is "an impenetrable fortress against even the most determined thieves”.
