does weather affect lubricants and fork/ammo's oil/air ??

Devastazione

The temperature has skyrocketed in a matter of 2 days in my place. We went from 10° C to 20° C in 48 hours sharp. All of a sudden one of my bikes,actually the one I use the most,started to make some squeaky sounds from the ammo area,something I've took care of a week ago when it was freezing just by resetting some unwinded bolts. Same for the ammo air,it shrunk a bit and I had to pump it up a little on both bikes. I mean,I week ago the garage where I store the bikes was freezing cold,today you can pretty much work in there just wearing a T shirt.
Given the carbon frames,it's the squeaky sound that concerns me actually...

I have no idea what you mean by ammo. But suspension can be effected by temperature. Seals can go hard/brittle. Viscosity of oil changes, air expands in hot weaher.

ammo is rear shock,sorry. . Just an italian-american contraction...

Gas expansion is more or less proportional to air temp. If you double the temp you double the pressure (however you have to measure in kelvin). So it is pretty negligible.

Especially as the shock will warm up as it moves.

oil viscocity (if you are running crap oil) is going to make the biggest effect, but still 10-20 is nothing.

I went from -20 to 30 in a couple of day (courtesy of a plane), once ridden for a few minutes the fork felt the same.

If the volume stays the same, the pressure will change in direct proportion to the temperature. Tyres, forks, shocks all need attention when the weather gets warmer/colder.
