Nothing. Absolutely nothing.
My singlespped bike is grubby after the Llandudno ride mentioned by @si_c and @Buck above but it wasn't the dirt that was bugging me ... There had been a minor rattle coming from the front half of the bike throughout the ride and after 105 miles of listening to it, I was determined to track it down and eliminate it.
I checked:
I was testing by lifting the front of the bike, dropping it, and trying to hear where the rattle was coming from. It is actually quite difficult to do that.
- Headset (No)
- Quick release (No)
- Stem (No)
- Brake levers (No)
- Cables (No)
- Bottle cage bolts (No)
- GPS mount (No)
- Separate computer mount (No)
- Front light (No)
- Valve, valve stem nut, valve cap on front tube (No)
Then I noticed that the rattling disappeared if I applied the front brake. At that moment a friend came round and asked what I was doing. I explained about the noise and showed that it didn't happen if I dropped the front of the bike with the front brake applied.
My deduction was that something was loose in the brake itself.
My pal bent down and listened to the noise and told me that he thought it was coming from the front wheel. I was convinced that he was wrong but swapped another wheel in and discovered that he was right!
I stripped the hub down, greased all the likely culprits, and reassembled it. The noise is history!
It is amazing how annoying a subtle noise can be. My hearing is not very good so I miss a lot of such noises but this was just loud enough for me to hear it when I was riding, especially over rough road surfaces.
We'd suspected that might be the cause in my case too. The pal in question once had a wheel with a bit of swarf trapped in the rim. You could hear it tumbling about inside the rim as the wheel rotated.I've come across 'chambered' rims (double wall rims) with bits inside the void, I wish I could find decent quality single wall rims still.
