can I swap out a bb30 crankset (force22 for compact force 22) without damaging the bearings?

If so what tools do I need, given that I am not pressing any new bearings in etc

Hi @apc. The swap should be very easy. You will need a 8mm Allen key to undo the bolt on the drive side. It's a self extracting system therefore the crank will come off on its own without the need of a crank puller. Once that's off you pull out the spindle and non-drive side crank arm. Lightly grease the new spindle on your compact crankset and reinstall all the washers and parts the way they came off the bike. Tighten to a recommended torque.

Last but not least you might need to lower and readjust the front derailleur to accommodate for a smaller chainring on the front.

Cheers.

...obviously you will need the bb30 version of the compact crankset, otherwise it won't fit.

unless you use an adaptor (e.g. Wheels MFG).

True, but that negates the benefits of having bb30. Nonetheless you're right, it can be done.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot
