steel frames with thin tubes cannot be locked outside?
how thin are the thin steel tubes on high end bikes? if left outside, there are two concerns,
one, any scratches while locked to a biking post will weaken the metal over time, worst case senario the bike will crumple during a ride. solution, use a (LOL) toptube protector...
two, leaving your bike outside in the rain will cause it to rust, the rust will weaken the frame.
the reason i made this topic was because others said it was easy to crumple up high end bike frame while trying to steal them. the theif would lift up the bike itself and use it as a lever against the lock. on a walmart bike the lock will pop, on a good bike with thin steel tubes, the bike itself will crumple while the lock stays intact.
so the question is it is safe to ride these flimsy bikes. sure they might be light but i like to use and abuse my bikes, not baby them, they need to be able to take a thrashing and still get me to places.
