I need to replace my 2004 Manitou Axel. I want to get a good used Zokes, but how can I tell if it is trashed or in good condition? What do I look for?

Other than testing the functionality of the fork, i.e. does the fork perform properly and do all the adjustments work (and it should be on a bike to do this), all you can really do without taking it apart is check the condition of the stanchions for wear or scratches (and even then you're only looking at the exposed part) and check for bushing play and the general condition of the exterior. Make sure the brake mounts, if threaded, that the threads are in good order. Making sure the steerer is not cut too short would be essential.

If it is a steel fork - the only way to fly in my opinion - I'd start by checking it's alignment by using a Park FFG-2* into the dropouts. This will indicate if it's bent. Unless it's been bent before. Read the instructions at the bottom of the following:

* Or other brand. Cyclus (Germany) also makes a good one. See BikeToolsEtc. for this and other brands -

Well, since he's going from a Manitou Axel suspension fork and wants a Marzocchi suspension fork...steel fork? Surly or what? Why?
