Shimano Bottom Bracket tool for HollowTech 2 SM-BBR60 Ultegra or BB-MT800 XT
Description
These bottom brackets use a similar, but smaller interface than the standard 16-notch BB tool. This steps down a tool to fit them. Would work with most 'larger' bottom bracket tools. I have a cup-style one but others should be fine too. I printed in ABS with thick walls - print it as strong as you can. I designed this to remove a BB from a 2nd hand frame that I bought. Printed in ABS it got out a BB that had been in there for years. Don't know how much torque it transmitted but it was a lot. I was surprised a plastic part could work so well if I'm honest.
