Tool needed for Hollowtech II bottom brackets

[rockyraccoon]

I've just got a new hollowtech crankset and bottom bracket to replace my current square taper type.

My local shop wants £18 to replace a square taper for hollowtech (just service, no parts included)

I know how to remove the square taper (done it before). Apparently hollowtech are even easier to install/remove so I'd like to do it myself.


Wondering now what tools I need.


I'll need this one, right?

Now, could I get away without this tool (spanner)

Just the first one should be fine, as long as you've got something to turn it with

You need the star shaped one for the non-drive side axle cover. They could have just made it so that a 2p piece could do the job but being big business...

The big spanner with teeth is needed to tighten up the cups without scratching them - you could just as easy use a very old fashioned BB tool (the half semi-circular spanner with a hook on the end) but it does scratch a bit.

The Shimano big spanners usually sell on eBay for £7 posted.

A 20p piece will undo the star

Ah well - there you go. These rich kids with 20p pieces lying around!

I have seen one once

My apologies - I thought the first tool was the same as an IceToolz one I have, which has one side which fit snuggly onto the BB cups to tighten them and the other side does the star shaped bit.

It looks like the small side of the Ice toolz tool will do what you want, this is only going on the photo mind.

The one I've got flips over so that one side does the star and one does the cups of the bottom bracket. It even has a hole to take an allen key if more force is required.

The Ice Toolz tool works very well with little chance of slippage and subsequent damage, although you should also be using a torque wrench to tighten the cap, and the crank bolts if you are going to do the job as well as the bike shop would!

CRC are selling both tools for £12. The job is easy I replaced one earlier in the year in less than 10 minutes from start to finish.

the other issue is "facing" the rims of the BB shell. This means getting them 100% parallel. The tool is expensive and plenty of scope for cock ups hence I would personally spend the £18.


I have the tool now for removal and refitting and it is easy

Add another £12 if it requires facing (£30 total).

I read about facing BB shell and I have to say it is a bit controversial subject.

Anyway, I'm going to take it to my LBS.

Better safe than sorry!

thanks

I don't think it is controversial at all with those employed as cycle mechanics, and especially those who have witnessed many prematurely worn outboard bearings.
