For the past week I have been driven insane by a creak coming from what sounded like the bottom bracket. The noise only seemed to occur as I pushed down on the left side at first. The lunch time MTB gang offered various advice and tools on Tuesday. On the ride home that night the noise came from both left and right pushes and really started to make me crazy. It got so bad I didn't need the bell to warn fellow tow path users of my approach.
I have had this symptom before, then I found the problem was actually with the seat post. Alas this time the seat post was not the cause.
Tuesday night the bike was on the stand. I couldn't feel any movement in the bottom bracket. And as I don't have the tools to remove it I decided that removing that would be my last resort. Besides, the pedals had plenty of play in them. So Tuesday night I stripped the pedals, re-greased them and put them back on.
Alas, the creak was still there and drove the lads mad again on Wednesday as they let me creak past, I'm sure they just wanted some peace and quiet.
Wednesday night the bike was back on stand and following advice from my friend Mark I took the chain rings off and set about cleaning greasing and refitting them. I also took the time to clean the chain and rear sprockets and jockey wheels. Put it all back together, using White Lightning on the chain.
Todays lunch time ride was sound! That is to say sound-less from the bottom braket at least.
I'm looking forward to a nice cycle in to work tomorrow, without the constant creak, creak, creak.
Top 6 'bottom bracket' creak suspects
- Seat rails, where your seat meets the seat post.
- Seat post clamp, where your seat post meets the bike.
- Loose shoe cleats (seems I missed this off my original post!)
- Pedals
- Front chain rings
- Bottom Bracket
Having gotten so close to the chain set I must admit to needing a whole new one... Cycling to work certainly isn't as cheap as I had first thought. But it is much, much more fun
