A locking skewer should offer the security of a lock combined with the convenience of a quick release, plus there’s no keys to loose or combination to forget and they’re quite pleasant to use. However, ours rolled over like the proverbial labrador puppy when faced with some heavy-duty pliers.
Available in the standard 100mm/135mm lengths the Lock 'n' Roll's black anodized finish looks classy while the Cro-moly rods have enough rigidity for successful pairings with wheels and forks up to and including suspension forks. Familiarise yourself with their operation, practicing locking/unlocking as the diagrams printed on the reverse could be more helpful. Grease them lightly before installing as usual; locking the skewers shut by turning them forty-five degrees. To unlock, raise the bike 45 degrees in the air and open the lever as usual. Purchase against the frame ends is generally very good and some off road singletrack sauntering couldn’t reveal any obvious problems with wheel retention.
In locked mode, attempts to prise them open with my hands proved reassuringly futile. However, a wander round the web suggested they were readily defeated using heavy-duty pliers or a magnet… The latter worked but I later discovered slight play in the skewer permitted this. Fully home and it wouldn’t budge but pliers demolished them in 48 seconds, freeing the front wheel Similarly holding the acorn end with pliers and rotating the cam also induced release. Configuring each so they open in a different position might slow ignorant, opportunist thieves to the point they go in search of easier pickings but regrettably the existing design is too easily overcome.

Our test set were too easily overcome using commonly available tools.
Tell us some more about the technical aspects of the product?
Alloy/resin and cro-moly skewers, locks by rotating the skewer forty five degrees and closing shut. Effecting release requires the bike raised 45degrees and opening the cam as usual.

Tell us how the product performed overall when used for its designed purpose
When locked the cam wouldn't open by hand regardless of how hard I tugged but lifting the bike forty-five degrees and the system allows normal, smooth release-almost as if by magic. However, a quick internet search suggested certain weaknesses, including the use of a magnet. This tactic didn't work but our front skewer rolled over in twenty-six seconds like the proverbial Labrador when attacked with beefy pliers.
Tell us what you particularly liked about the product
Novel idea, nice, smooth cam action.
Tell us what you particularly disliked about the product
Our test sample offered very little security.
Did you enjoy using the product? Yes, until the weaknesses became apparent
Would you consider buying the product? Not on the strength of our test set.
Would you recommend the product to a friend? No
Anything further to say about the product in conclusion?
The UK importer were very surprised by my findings and have requested their return for further testing so as to determine whether ours were simply a rogue set, or whether there is a specific weakness in the design.
