My local tips are run by the same company and the county council sets targets for recycling. They sell anything that they can and making friends with the guys that sort the stuff can get them to give you the nod on decent kit. Recent finds include a marin shoreline trail frame, an M-Trax road frame with ex300 kit, and an carrera Kraken- complete.
legrandfromage is the king of the skip monkeys on here, some of the stuff he gets is incredible.
Condition is not great but you are not getting gear thats been looked after!
Cheers
