Took apart the kitsuma to change the stroke from 57.5 mm to 65 mm.

I used the same shimano bottom bracket tool to take the air spring body off the bottom eyelet that the double barrel uses. Then I put the 9.5mm shaft in my vice clamps, warmed up the eyelet body with a heat gun and removed the eyelet body, then the white plastic spacer.

This made the 57.5 mm shock into a 65 mm shock. If you want to make it a 60 mm stroke you will need a 2.5 mm spacer.

One interesting addition to the shock shaft was a 4 mm hex on the end of the shaft to be able to remove and reinstall the eyelet body onto the shaft without a 9.5 mm shaft clamp.

The shaft sealhead can be removed with a park pr2 cassette tool.

About to do the exact same stroke change to my Kitsuma Air. Can you point me in the right direction of the tool you used to remove the sealhead? I can't find the Cane Creek tool (BCD0344) anywhere. Something like this?

BB Tool HT II - Spanner Fitting
park pr2 cassette tool


This is the one I used.

If you are doing a kitsuma you don't need to clamp the shaft to get the eyelet off. The eyelet has provisions for a hex key on the end and you can unbolt the eyelet after heating it uo and releasing the loctite.

Really appreciate the response on this! The tool I am referencing is on step 2 of the guide below. I guess I don't follow how a cassette tool fits over the damper shaft and onto the splines of the sealhead.

The rest of the process seem fairly straight forward

thanks again!

You don't need to remove the seal-head. You need to remove the eyelet from the end of the shaft. Shaft clamps if you haven't got the through hole and eyelet bushing out.

Pretty sure it's not a cassette tool for the shaft, it's the bigger ISIS BB tool like the Fox X2.
