Can anyone tell me which tool i need to get the BB out of my Zesty??

Shimano Integrated bearings BB SMBB7141A. That’s what it’s listed as on the spec sheet..

Cheers.

One of these and a hammer:

I ended up just paying my local bike shop a tenner to remove and fit my new BB on my Zesty as the cost of the tools for the job worked out at about £50 when i looked

Bucko, did you buy the BB from the shop? Wondering if free/reduced cost fitting could be one of those places where a LBS might compete with online shops.

No I bought it from welovemountains online and had it fitted at my LBS. £10 is their standard minimum labour charge
