    Hi

    Can anyone advise me on what specialist tools I need to service/replace a shimano bracket. My road bike and mtb both have shimano BB's and I would like to be able to service these myself to keep them in good condition.

    Thanks for any replies.

    If its Hollowtech

    Mind you, no real maintenance needed on Hollowtech BB's. Mine is over 7 years old and still OK.

    I would be fairly sure you need either a Park BBT-9 or if you prefer to use a socket set a Park BBT-19.

    It also has '' do not disassemble '' printed on both BB's aswell.

    A Mountain Bike? ...whats that? :D
    When you say you get 6 months, what maintenance do you carry out on the BB? I assume you simply replace it? Cups and all?

    Not much maintenance you can do really! Hardly worth trying to change bearings in them given that you can buy XTR BBs for about €35 these days! But you're right, the road bike's seem to last much better!

    This plus a 5mm Allen Key for the left crank.

    then onto Youtube and search for "Shimano Hollotech chainset removal"

    Depends on the cranks! Some cranks require an extraction tool! I need one of these for the mountain bike.

    The Park Tools website is a great resource and their maintenance book is a good purchase too!

    Agree, I'd buy a good set of Allen keys before spending any money on BB tools.
    then a chain breaker, tyre levers, track pump philips screwdriver...etc etc...
