ConsNot as good as 30 year old ones I have.
Can't find these anywhere else, except on Ebay. Good price but unfortunately the quality is not quite there, or else the stock is old. They need to compress concertina- like when fitted but the plastic is too stiff. I had to heat it in hot water to soften it.
Perfectly designed for the job.

Just a bottom bracket plastic protector but nowadays these are getting harder to find...except if you go to SJSC. They are good for hard to find, older parts.

Does This Sleeve Fit Over A 30Mm Rotor Spindle With Bb-86?
26 Aug 2016
I have a planet-X with press fit bb-86's and a rotor crank.

I'm afraid not, this is designed for use with traditional cup and cone style bottom brackets.
