how long do you change your tyres and chain?
i know ppl will say when the tyre turns bald den go change. but due
to whether of singapore, tyre will have some crack lines. dunno
will it burst while riding....heard that even its not completely
bald, still haf to change.
as for chain....ppl said that the chain will get some sand stuck in
between...after sometime, the weakest link will snap off and might
get the chain stucked in the sprocket while riding.
