    Upgrading from Tiagra to Ultegra R8000

    I am upgrading from Tiagra to Ultegra R8000. I am planning on doing all the work myself. The only part I am doubting I can handle is the removal of the BB71-41 bottom bracket.

    Would it be advisable to replace the bottom bracket (3 years old) at this time?

    Unless it's giving you a problem, there is no need.

    Echoing goodboyr, it's not obvious what you would gain from this expenditure. Replace things as they wear out or cease to operate properly.

    Regards the BB, age means nothing. If you didn't ride the bike for three years then there wouldn't be a reason to replace. If you rode 10K miles per year, then maybe it would be worn out already (or maybe not). If the BB turns smoothly with no wobbles, it doesn't need to be replaced.

    You'll need an 11 speed compatible rear wheel.
    I work for some bike racers
    I've got some bikes, some guns,
    and a bunch of skateboards

    Thanks all for the input, no issues with the BB. Just wanted to make sure it wasn't a situation where the BB wears with he old crank such that the new crank would fit poorly.

    I have a 10 speed cassette and when I purchased the bike. Seller confirmed it was fully upgradable to an 11 speed cassette as that was always my intention.

    It is a giant defy advance.

    If it's a press fit BB and there are no problems with it, don't touch it! If it aint broke..............

    Not in the way you are worried about. Any wear issues would be evident with the old cranks not hidden by them.
