Did a bit of a search but there wasnt anything very useful. Just a lot of spam. Does anyone have any real world experience here with disc locks, has anyone ever had one tampered with, or attempted to remove or cut and failed? Which is the best brand, not looking to go to a shop, looking to specifically search for a recomended brand and purchase via ebay. Cheers in advance peeps > also , anyone have experience with iPhone holders on the handlebars?
