There's a first time for everything
Always grease the pedals after cleaning the threads.
Have lately got into the habit of cycling a lot with only top gear and bike weighs in at 25kgs, up hill as well
The pedals I use are cheap wellgo and need constant maintenance as they tend to wear quick.
Normally they have been ok and even when they develop slack remain some what quite.
On my way home a few days ago and noticed that there was a funny click clack from the LH pedal ever power stroke.
Stopped and checked pedal a little slack in the bearing but nothing unusual.
Carried on and it was back on a hill.
When I looked at bike I forgot about pedal noise, well actually couldn't find anything wrong so thought I would wing it one more time.
But at a late hour decided to take pedal off and dismantle.
Got spanner and went to undo..............all too easy, nipped up but not tight, more like Apollo bikes when you take them apart after little use abandoned in garden.
Tightened it up and that was that, next day no problem.
So, forgot to add that I normally use a pedal washer (standard 12mm washer opened up to slip over thread) it does sometimes deform.
So I deduce that my over bearing stomping on the pedal was / had loosened the pedal, maybe wasn't tight enough or the washer deformed some what.
Then the clicking noise and on releasing effort the pedal under went precession thus when I stopped the pedal was not loose?
Have to keep an eye on that perhaps better washer, reason for washer is to balance the pedal distance from the centre, about 3MM.
). Ten miles down the road the threads stripped. The pedal had not precessed as it would have normally. Fortunately the crank had enough threads in the back of it that I could carry on using it....
