When this arrived in the post we weren't quite sure what to make of it. It's basically the biking equivalent of one of those gizmos your gran uses to get the lids off jam-jars.
The idea is that if the lid on your CamelBak's Omega bladder has become jammed shut, the Slug will give you some extra leverage to wrench it open.
It's essentially a plastic handle with an S-shaped groove at one end that grips the turning handle on the lid.
Initial reaction in the BikeRadar office was 'why on Earth would you need one of those?', but some of the female staff members admitted they'd had problems with seized bladder lids, so maybe there is a market for it. And at £4.99, it's not going to break the bank.
The Slug is made by a new Lake District-based company, Xtreme Design Kendal, from recycled materials. XDK's Chris Gawith said: "I am well aware that some people have never had a problem with Omega lids getting stiff or seized, but I also know a lot of people who do ride very regularly, and know it's a little problem."
We'll put it to the test and let you know how we get on. Is this a product you've been waiting for all your life? Let us know in the comments box below...
