Anybody have experience witht his fork? I've been looking for a 150mm upgrade for the Z1 FR on my Bullit. I do have quite a bit of climbing on most of my rides. Is this fork OK on climbs or should I find something with lockout? Is it taller then the Zocchi 66 150? Any info would be great. Thanks!

The largerst difference between the TPC+ damper and Intrinsic is that the compression circuit of the TPC does not have any elements which prevent bottomout. Intrinsic, like SPV, has an oil metering valve which begins to shut at the bottom of the stroke, so if you're taking big hits with the fork, you're less likely to bottom out the Intrinsic.BMW2006 said:

No, what that position sensitve piston does is provide pretty much no damping initially, or for the first 40 or so mm of travel, then the "normal" compression piston kicks in. It might be position sensitive, and in a sense it makes for some progression, but it doesn't really keep it from bottoming out, unless you increase the compression damping dramatically, and in that situation you'd have a pretty big "spike" as the fork's velocity changed drastically through the travel. It's not really bottoming resistance at all.XSL_WiLL said:

Yeah, that's a rad price. Jump on it. the cheapsest ones out there now are around 550 at AEBike.comBMW2006 said:
They were 425 around Christmas time, I should have got one then.

In addition to what Jm said, the Intrinsic does not have a pedaling platform. That's the whole idea behind the damper. There is a sping which kicks in at full extension, which keeps the SPV valve open, so you have no platform and full bottomout benefits.XSL_WiLL said:

The spring holds it open for longer than the original SPV air system, but it doesn't keep it open and eliminate the platform.MK_ said:
The platform is based on oil displacement rather than air pressure, this eliminates the "notchy" feeling which was the bane of the original system. There is no initial platform in the very begining of the stroke, as the suspension compresses, SPV kicks in harder, 1. allowing for pedaling platform 2. providing bottom out resistance near the end of the stroke.
My experience with riding these forks and having them apart completely contradicts everything you and Jayem have suggested about Manitou's damping systems.
The two of you are giving the wrong impression and under estimating them to an almost slanderous degree.

Could you be more descriptive?mattsavage said:
To my understanding the way SPV works is as follows:
The oil metering valve is closed at full extension and the force which keeps it closed is controlled by the pressure of the air in the chamber. It then is forced open by the flowing oil. As the fork compresses, oil reduces the SPV chamber volume, effectively increasing the force of air on the metering valve. At the bottom of the stroke, the air pressure is so high that the valve begins to close, resisting bottomout.
On to intrinsic, there is a spring which keeps the valve open at full extension. So I imagine after certain amount of compression, the spring is fully extended and the SPV works as usual. But you can call it platform or you can call it compression damping. Since the oil is flowing, the valve should be kept open, so it doesn't seem to me like it is a platform. At the bottom of the stroke, just like SPV, it resists bottomout.
Since you had the fork apart, can you comment on any type of additional compression/rebound shims on a piston?
I do not mean to spread misinformation. There is so little info about intrinsic that I am simply piecing the little info that I have into an educated (somewhat, at least) description. I would appreciate if you would reveal all you know about the damper to fill in the gaps.

You were right, I was partially wrong.MK_ said:
I see now what it was you were saying in your previous post. I completely misinterpreted it. I thought that 1.you were saying there was NO bottoming resistance with the Intrinsic system and 2. that there wasn't any sort of low speed compression damping.
There is low speed compression damping, it just shouldn't be refered to as a "platform" in the new Intrinsic. Alot of folks, myself included, throw that term around too loosely.
