Which tools do I need to replace a bottom bracket

[jayonabike]

Shimano Ultegra, and is it an easy job? The winter has taken its toll and the BB is creaking. Still it's done over 3800 miles so I can't complain!

Thanks Ian, looks straight forward, so I just need to buy one of these

 

[ianrauk]

You do.. but I would get one of these instead and use with an adjustable spanner. Reason being, the one you linked to can bite into the Bottom Bracket splines. The one I linked to, there is less chance of that.

 

[jayonabike]

Ah ok, thanks. I take it the other side does the crank?

No the other side is a cassette removal tool.
To remove the crank you need one of these

Remembering that the crank nut only needs to be finger tight, not forced tight.

If you want to get the torque roughly right, use a spring balance fitted through the hole at the end of the adjustable spanner. Alternatively, with the Park Tool gizmo, fit it directly.

Edit: Sorry, cross post. I was referring to the BB tool, not the crank one.

3800, that's rubbish. At least they are cheapish.

That's all winter miles, this years and last.

Still a bit rubbish. Got 20,000 on my fixed BB and they take more strain (old fashioned square taper cartridge).

At least the Hollowtech is a doddle to change.

That's good to know, thanks again

I love the look of @ianrauk 's Lezyne tool, but Superstar Components sell a similar version with a 1/2 inch socket drive for £7.99. http://superstar.tibolts.co.uk/product_info.php?cPath=36&products_id=368

You'll need a preload nut tool as well, cheap as chips

and a 5mm Hex wrench to remove the crank pinch bolts
