Nope, same. A 6" 66 SL has the same a-c as a Z1. Unfortunately there are no 6" 66 Light or 66 RC2Xs available in the US as far as I know (I want one though).

You might want to double check your #'s
The new 66 has a 10mm lower axle to crown than the current Z-1's

I have a few differnt models here set with various amounts of travel

my 66vf2 set at 90mm has a 490mm axle to crown height

my z-1 set at 65mm has a 475mm axle to crown .

You do the math that's 10mm of differnce , this comes from the lower axle placement on the new 66 lower's

Now on to the fabled 6in coil sprung 66
They make a 7in 66vf2 , this fork can be reduced with one of our travel reduction kits to 6in very easily .

The new vf2 damping system is very similer to last years hscv cartriges , with the way the valves are designed . Acording to Zoke this is the system Ronnie and the tech guys have been waiting for !
Now with the external rebound and compression ajust you can tune this fork to feel better than last years 66rc .... NO JOKE !

MY 90mm version feels like a mini fox 40 or better !

Hope this helps !

Thanks for the input. Let me clarify what I am looking for. Right now I have an 05 Z1 FR1, 150mm. How will the 66 Light with 170mm of travel compare in axle/crown height when both are fully extended or unloaded (I am assuming the sag will be about the same for both)? From what I have heard it sounds like I can gain 20mm of travel with the 66 Light and change my basic geometry very little.

Yup
If you run the 66light it will only have a 10mm taller axle to crown @170mm
than your current 05 Z1 FR1 @150mm , this shoulnt change much on your bike and this could be taken up by adding a hair more sag as the 66 is just so buttery you can get away with 15mm of sag .

05 Z1FR1 150mm, a2c = 538mm
06 66 170mm, a2c = 555mm

to me, that is big change in geometry.
some people will disagree.
You will have to find out for yourself.

While descending the sag may feel similar but when on flat ground the taller fork will feel taller.When climbing the 170 would feel a lot taller because you will lose your sag but the Light has ETA so it will still climb well.

Sounds like a good choice,but it is about 2lbs heavier and i don't like bikes with more travel in the front than the rear.If you have a 7" bike go for it. If you have a 6" bike it will suddenly make the bike feel a lot heavier and slower-if you climb.

Thanks Krispy

After reading your post I'll probably stick with the Z1. I have a 6" bike (Uzzi) and did not realize the 66 Light weighs that much more. The trade-off doesn't seem worth it.

2 pounds?

I don't say that as a challenge, as I don't have the weights on anything but the 66SL, but I didn't realize that the 66 Light was that much heavier than the 5.7lb. SL. I thought the weight on the Z1FR1 was about 5.3lbs. I just didn't realize that there would be that much difference between the 66SL and the 66 Light. Does anyone have the exact numbers?

Marz says the 66Light ETA is 5.9lbs without steerer, 6.54lbs with. They've been pretty close the last few years with their weights. So that's basically a pound heavier than a Z1.

I may be getting one tomorrow (depending on if there was anyone home last week when I sent in my order form), other wise it will take a while. I'll try to remember to weigh it.

Z1 FR1 weight is 5.5lbs - I weighed mine with a pretty accurate scale before I put it on. Steerer tube was cut, but not very much - ended up being a little longer than 9".

I noticed they're almost always out from Christmas until after the first. Please check out that weight when you get it.

Actually a 6" 66 has a 535mm a-c while a 6" Z1 has a 538mm a-c.
