Heelo, I got an Abus X-Plus 54 and pitlocks for both wheels and seat. The pitlock for seat post is nice, but I donīt like the pitlocks in wheels since I fell they reduce the performance of the bike, Trek 7.3, I am not sure if I am right or being paranoid , but any way . since I can use the abus for rear wheel and frame. Does anyone know another security system for front wheel, I donīt want a second U-Lock, too much weight. Is there any small and secure locks sepecific for this?
