Ive fitted these a few days ago and they have the fiddly friction fit, now ive noticed that on a portion of my pedalstroke i get what feels like a clunk or at least some play, when i actually wiggle the cranks they're stiff as anything and i know the bb is fine.

So am i right in thinking they're just bedding in and will need a bit of fine tuning?

Also do you or don't you grease the splines, mine was but tomorrow they will be thoroughly degreased.

Any thoughts?
The trouble with having an open mind, of course, is that people will insist on coming along and trying to put things in it.

  • I didnt have any bedding in period where I noticed any mechanical difference.

    Hope this helps
