While out yesterday I hit a pothole, resulting in a loud cracking sound and my bars slipping down a little in the stem. I adjusted the bars back up, had a quick look round the bike, couldn't see any obvious damage so carried on.
A while later I became aware of an ominous creaking sound, worse when I was out the saddle.
Oh dear, cracked frame or forks? Damaged headset? Broken spoke? Loose bottom bracket?
Nah, none of the above. I just hadn't fully tightened the front QR before I left home.
So, not much fettling needed. Just be more careful next time.
