im bidding on a hope one now with 10mins to go :cool:

i bought one recently for the fatbike and its been great, £17 new isnt bad either.
 
a hope clamp is the only clamo I have ever had that failed to stop the post from slipping - the hollow alloy bolt started to stretch!! I made the alloy 'nut' and am using a steel bolt and no problems whatsoever.
 
I missed out on a black hope clamp, settled for a basic £6 quick release instead, will see how it copes.
