Ok this is the start of an archive of helpful fixes that I will build up as and when I find them out

Cannondale

1) Creaking/ Clicking noises from rear end.

Got a Creaking/ Clicking noise from the frame/ swingarm area of your Cannondale Prophet/ Rush, have you tried all the usual things that may be causing the annoying noise, such as the bottom bracket loose/ worn out, the bolts loose for the front chain rings, Suspension pivot bushes worn out, the Seatpost clamp not tight enough, Seat rail clamps loose? If the answers is Yes and you still have an annoying Creak/ Click then check out the swing arm at the bottom rear (side nearest the tyre) by the pivot, If there is one of the numbers in the table below printed on it you 'May' require a new swingarm. check out this link from Cannondales own tech section for further information and also helpful advice on general noise sources.

This was According the tech note, only on 2005 models But there is also general advice on the tech note for locating/ diagnosing noises on any age Prophet/ Rush or other?

2) Lefty Max 140 SPV, Top out metallic knock noise.

If you have got a knocking noise as the fork tops out after being compressed, try checking the pressure in the SPV chamber! Chances are that the pressure has dropped over a period of time, 30 PSI is supposed to be the minimum pressure that the chamber can run at but I found that this causes a light metallic top out noise after the fork has compressed and is returning to its full length. I weigh around 11 stone and have the pressure set to approx 50-60 PSI in the SPV chamber and 9 clicks back from fully wound in on the Rebound dial (be VERY cautious not to wind down the Rebound dial too hard when winding it in fully, only light action is req'd to turn the dial and you should stop once resistance is felt, then you should be able to feel light clicks every 8th of a turn or so of the dial) I found that from Min to Max of the rebound dial is approx 14-15 clicks MAX any more in either direction and you will probably have to remove the top cap of the Lefty and unscrew the rebound plastic threaded adjuster then refit the top cap ( here is the Shimano BB hollowtech II tool for the lefty top cap removal). Full Set up and Tech advice for the Lefty MAX 140 can be found by clicking this Cannondale Lefty MAX 140 Owner/Tech note link.
