Bottom Bracket tools for Tiagra

Hi

I have an annoying clicking sound which is quite rhythmic (i.e. - as the pedals revolve). It started out just when out of the saddle/pushing hard while seated, but now happens more often.

I have already regreased the cranks and pedals. What tools do I need to re-tighten the bottom bracket?(As it shouldn't be at all worn, having only done about 500 miles.)

The crankset is a Tiagra triple, but I have no idea what type of bottom bracket that uses. Any help appreciated.


Thanks

    If it's pretty new it's probably got a hollowtech 2 BB.

    When tightening the left crank arm make sure the bolts are properly tightened and the pre load nut is not in tight, just snug as someone told me. Hopefuly unlike me your clicking will go away forever.

    Does it look like this:

    If so, then you'll need a Hollowtech II bottom bracket tool which you can find on most website or in most shops.

    If it is this BB the good news is that it is almost certainly the source of the noise and it's very easy to fix. Simply take it out, clean the threads (on the BB and the frame) and put it back again with a bit of grease. If you want to stop the noise recurring consider wrapping some insulation tape around the join between the BB cups and the frame to stop dirt getting in.

    Thanks all

    Yes Simon, that certainly looks like the one. I'll get myself a hollowtech II tool and see if cleaning it stops the problem.

    Will, just to check I've understood you - do you mean that the pre-tension nut that goes throught is just that, and that the crank is actually held by the bolts?

    edit: Probably won't get the tool til mid week - will riding the bike with the click in the meantime cause any damage?
    Thanks

    Nope, riding it with the clicking won't do any damage. You're right about the bolts too, the reason the cap is made of plastic and has a funny shaped bolt head is to prevent you from overtightening it...

    Stripped it down last night, regreased and replaced and no clicking this morning! Fantastic.

    Thanks again for the advice.
