Ok, that's two words... Been on the bike for about 8 months and when I got the bike, I was told 'oil and typre pressure'. The last week or so, the handling on the bike has felt a bit weird. Went for a run along le boulevard today and I could tell something wasn't right. I was -12 recommended psi on the front and -6 on the back. Any noobs like me who haven't taken the time to check your pressure, do it.
