as i am getting a new tyre I thought i would try out the GRYP puncture kit that i have carried around under the seat for ages . I drove a screw into the tyre , removed it and let the tyre deflate, following the insuctions I reamed the hole out ready to accept the cord covered in adhesive, pulled the cord through the bodkin /needle but could I get the cord through the hole , could I fuck .so I would advise people not to buy one of these types ,I think gryp do have other types of puncture kits but this type from my experiance is rubbish .the typei am referring to comes in a carry-case with plyers, air cartridges ,reaming tool.core inserting tool and several cords coated with adhesive. do'nt buy this type
