While I understand the frustrations with stylistic and grammatical errors in internet forum posts, the OP was clearly written and grammatically correct. Please hold on to your inner editor until the next person writes a punctuation-free post about how he "looses break function" whenever he squeezes his "break handles to write about their." You may have to wait five or ten minutes for this post, though.

Edit: To the OP - do search the 'stickys' at the top of the forum, try a search on "chain skipping," and be sure to visit SheldonBrown.com as that is the best source of bicycle technical information in existence. Then post back when you need some clarification.
