Subject: RE: P2-SL Rear Cassette Fell off Every bike I have ever owned came loose a while after I rode it after purchase. I believe that it is just the normal break in of new parts. It requires an inexpensive tool to tighten it and often will show symptoms of somewhat decreased shifting or additional chain noise for a while before it gets really loose. Spend 2o bucks on the tools, check it every few rides and dont worry about it. |
