Greetings, My VT3 is fitted with a Swinger SPV air shock on the rear. I'm curious to know how often I'm going to need to check the pressures. The shop set the bike up when I got it and wrote down the pressures they'd set, but when I checked it on the weekend, they were quite a bit lower than that. It's only had a little bit of riding since new......probably 50-60km of 'proper' offroad riding, plus a little bit of 'commuting' riding thrown in. Is this the sort of thing I should check prior to every ride? I inspect all the obvious stuff before every ride......tyre pressures, chain condition, brakes and such.
I'm actually getting some serious withdrawl at the moment.....my GF has been sick with the flu, so we haven't been for a ride in over a week!! Hate that :-(

With most pumps when you check the pressure, some air escapes into the chamber of the pump giving a lower pressure reading. Bit like the rule in science that says whenever you subject something to testing the results will always be skewed by the act of testing itself. Theres probably a catchy name for it but I forget.

The technical term for this phenomenon is, "Psssssss!" (For high pressure road tires, it's "THWAPP!!!"😉
