Having just bought Shimano SPD clipless pedals, I need to remove my existing toe clip pedals. Can someone tell me which way I unscrew the pedals ?
I thought the guy at the pedal shop told me to unscrew the left pedal anticlockwise and the right pedal clockwise. But having just watched the relevant video on biketutor.com, they say the left should unscrew clockwise and the right clockwise. Can someone confirm the the correct way of doing it before I botch another simple job? Cheers.
OK, for the benefit of everybody, regardless of clocks. If it is a right hand screw thread (as most screws are) take your open right hand and point your thumb in the direction you want the screw to go (i.e. in or out). Now curl your fingers to make a fist. The direction you curl your fingers is the direction you turn the screw driver to make the screw move in the direction of your thumb.
For a left hand screw thread, you do the same thing but with your left hand.
On a bike, AFAIK, the only left hand thread is the left (non-drive side) pedal [Please correct me if I'm wrong]. Gas bottles are also left threaded which is important for the barbeque after the ride.
I teach this screw rule to my first year uni students all the time. I think it's fool proof. They seem to think memorising "Righty tighty, lefty loosey" is easier. Kids is stoopid.
i saw one of the TV home improvement shows the other day with a segment on replacing shower heads.
the presenter advised the viewing audience to remove the old head by turning the spanner clockwise ... as the vision showed him turning the spanner anticlockwise (a-c being correct to remove water pipe thread).
i wondered how many people were madly writing down the verbal instructions or downloading the program transcript and later stripping their shower head threads!
I'm a pretty simple guy *wife nods vigorously*, I turn the crank in the direction that I would normally pedal, then turn my Allen key and/or spanner in the opposite direction to that.
Me pedaling will always tighten the pedal.
Striving for mediocrity.
Oops. And rhs bottom bracket cups (on English BB cups at least)
Mandatory helmet law?
"An unjustified and unethical imposition on a healthy activity."
Put the spanner or allen key on, hold it still and spin the cranks backward to tighten, forwards to loosen.
Don't forget to flip or hang the bike first
...whatever the road rules, self-preservation is the absolute priority for a cyclist when mixing it with motorised traffic.

Be careful though... the guy in Biketutor.com has an American accent, so his advice will only be good for the northern hemisphere...
If water runs the opposite way down a sink in the southern hemisphere, it stands to reason that pedals will tighten the opposite way as well.
Hope that has cleared things up.

How many forum members does it take to advise a newbie how unscrew a pedal?
BTW, lisanne's advice works for me.
