Yeah i remove the cranks, rotate and regrease, strip the pedals to check
bearings and regrease, check the bearing holder bolts and seat bolts on
my Muni. I do it less on ym trials but do also rotate the tyre to stop
getting a flat spot. Incidentally this is for splined cranks, if you
take square tapers on and off you'll eventually wreck them and the hub!

I mostly only maintain stuff if it starts making a noise, or not
working.

I grease the DMR pedals on my coker every so often, cos they've got a
handy little grease port to put grease in, otherwise they go clicky
after heavy rain.

If I stripped it down every 30 rides, that'd be once a monthish, I just
don't have the time. To be honest, I think doing maintenance when
you've not got problems isn't a good idea, cos doing the work can cause
problems.

Do they have a handy grease port to ease regreasing after lots of water
has got in through the handy grease port? :)

Why if you are rotating the cranks do you rotate the tyre aswell?
Surely if you rotate the cranks then you have effectively rotated the
tyre as the cranks line up with a different part of the tyre. Infact,
if you rotate them in the same direction then you will end up causing a
flatspot on your tyre rather than preventing one.

They have a handy allen key stopper that sits in the handy grease port
to stop rain getting in.

Explanation needed, as my trials has the modern KH cranks i feel the
need to rotate the cranks only infrequently, the tyre needs rotating
more than this so it needs to be done on its own sometimes. Obviously
if i was rotating the cranks i wouldn't do the tyre aswell. In any
case, I would only cause a flatspot if i rotated them the same amount
in the same direction, which is unlikely to happen.
