I read posts on a forum where guys ride long distances (Audax) .... many bought them for Audax rides....

when doing an Audax ride, you have to have your card stamped at places such as School halls etc .... all you need is a lock to lock your expensive wheels/dynamo hub for a few minutes while you enter the hall

so this is perfect .... it's light and it's secure for a few minutes ... a thief will take another bike thats not locked

I will be getting one ... the guys who have recieved theirs from the Kickstarter project are well happy so far, but have only recieved theirs this week (in the UK) ... many had to pay a bit more for custom duties

however.... I would not lock my best bike in the city with this while I go shopping
