Hallo Dirk, Try use a Star washer or loctite 243 Serge Dirk Bonné a écrit :
Hej Sten, It is good to hear I am not the only one. I'll have to check if there is a tolerance on the BB, although that doesn't worry me. Tolerance doesn't matter for the riding experience. Tacking the shell seems a little crude. I'll try clamping it down using a bolt and large washer, having the washer pushing on the shell, keeping it im place. Something like that anyway regards, Dirk On 03.08.2010 22:10, S.

This is the cours that the shell is unwinding itself during left-cornering. If you have plenty of hight you can built in a profesional bearing as used on mounten bikes. I did not have this, but leurned to live with it. You can give it a tack weld, but the clearens will stay.

It keeps getting loose, because the upper shell keeps unwinding (after 100kms I need to re-thighten it). I know there are others which use this solution. Am I the only one with this problem? regards, Dirk ============================================================ This is the Python Mailinglist //www.freelists.org/list/python Listmaster: Jürgen Mages jmages@xxxxxx To unsubscribe send an empty mail to python-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field. ============================================================-------------------------------------------------------------------------------- Geen virus gevonden in het binnenkomende-bericht.
