65rpm-does that means 65 revolutions of the pedals? As that seems quite slow. What does changing the sprocket do? When I watch the video of prestegne on youtube the Kalkhoffs on there seem to be being pedalled alot faster than 65rpm.
Someone I worked with used to have a cycle alarm. It didn't take long for people to notice, and in the end he had to take it off. He got fed up with idiots deliberately making it go off constantly.
I am new to this site. I think it is fine as it is though. Why do people have to keep changing things? I mean we all no what a mess Consignia made of the post office. Now Aviva is the latest!
How about getting an angle grinder to the bolt flats once you fitted them, no one can remove them then. You're buggered if you need to remove it though.
