So had a serious brown trouser moment on this evenings ride, heading down a decent long hill in a group at around 40ish... pulled out to overtake my buddy, and a large 4x4 overtook as well relatively close. All of a sudden the bars started vibrating and steering wobbling, thought I had punctured and desperately kept it in a line as I braked gently.
Managed to not take anybody out and stopped. But no puncture.
Is this something to do with the wind from the car? I was using cosmic carbones so fairly deep rims.
Really want to avoid that again was close to biting the tarmac and taking mates with me.
(only be road riding 1year/2500 miles so still a relative novice in group riding)
