Dahon Bottom Bracket – Loose

Monday June 8, 2009

I think I’ve mentioned before, either here or over on the Dahon Forum, that my D7HG makes a ‘clunking sound’ when I pedal.  This has been happening more or less since I bought the bike but I finally worked out what it was last weekend when out cycling.

I had initially thought that it was related to the internal workings of the Nexus hub and the drive mechanism ‘catching-up’ with itself as I pedalled.  I left it at that and just lived with it.  But then, as I cycled recently, I thought more about it and looked at the bike as I slowly cycled along the flat.  Then I realised that it was the bottom bracket – the piece where the pedals attach to/through the frame – it was not loose (see photo below).  Not sure if this was an original assembly issue, pre-sale check issue or it had just come loose.

Anyway, I needed to tighten it up and didn’t have the right tool for the job so I headed to my new favourite bike site Dotbike for a BB lock ring tool.  Now the lock ring and bottom bracket are correctly secured and that should stop the clunking noise as I pedal.  I now need to get out and try  it, but that won’t be today.

I also grabbed myself an Ice Tools Spoke Wrench.

(Hmm, why do my bikes always look dirtier in photos than they do in the flesh?!)
