These bars have been given to me by my local bike shop, (Lifecycle UK in Bildeston, Suffolk), to be sold in aid of our EAAA (East Anglian Air Ambulance). This is a something they do when they have old stock, or part worn parts that have come into their workshop, but they will not be able to use and are too busy to sell on ebay, as I do (I am retired, you see) I am a member of the local cycle club, (Cycle Club Sudbury.
These came in small bags labelled, as you can see, "Hunt Carbon". I believe these are shoes specifically for carbon rims whether made by Hunt or any other manufacturer.
I have several other bundles.
