I put a Marzocchi ZI Light ETA on my 5-Spot. The first one leaked oil and needed to be replaced...I have not put enough time on either to break them in.
So far I can tell you that it is better fork than either my the Fox Vanilla 125 or the Maverick DUC I had on there previously. Axle to crown on the Z1 light is a little long on a 5-Spot but is cancelled out by the ETA when climbing. With full travel coming out of a whoop-de-do uphill can make for a very light front tire , with the posiblity of washing out the front tire. So I need to attention to weighing the front tire. I have been running the fork in 6 inch mode, you can crank it down to 5 inches that the frame is designed for.
I am thinking that some of those fork suggestions above are jokes or people only want to go downhill on their bikes.
My vote Z1 Light.
