ASR7 with dual crown (40 or boxxer), Ride reports?

[KrisRayner]

I've been contemplating a Van 36 180 for my 7 for shuttle runs. However I've noticed that the axle to crown height for a 180 fork and a 203 dual crown, like a Fox 40, is only a 5mm difference. Drop the 40 by .5" and it's mute point.

For those that have run a 40 on there 7, any problems you've run into? With the A-C height being so close I can't see it really being a problem for frame strength. Handling changes?

Man I have never seen one (ASR-7) setup like that, I know for your shuttle runs, you may not be worried about any weight, but the Fox Van is a great fork, and saves you that extra pound of the 40. Not to mention the extra overall bulk of the 40.

I would'nt knock it if some one did it, just seems a bit overkill to me. But hey there is always a first time for anything.

I'd run your idea past the people at Yeti before you try it. Dual crown forks tend to exert a larger force on headtubes than an equivalent A-C single crown fork. They'll pretty obviously say that it'll void your warranty but they might tell you if the frame is suitable for a dual crown fork or not.

I have seen a dual crown on many other AM frames, Nomad specifically. Honestly a single crown 180 coil like the Van or even a Totem would prove to be much more playfull and still plow!

I've seen d/c forks on the old style 575. This was 5,6, 7 or 8 years ago so they probably weren't 180mm forks. This doesn't answer the question but....

Bear Grylls drinks his own piss; doesn't mean it's a good idea... if you catch my drift.

Here's the picture that got me going on the whole thing.

I don't have a 7, but I have a Canfield One with a Boxxer, which seems like a similar bike: long travel trail/"all mountain" whatever that means.

I have the Boxxer WC, which is an air fork, and I gather not what you were thinking, but it's lighter than a Totem or 66, and as you noticed has about the same axle crown. I'm very happy with it, even though it's never been on a lift or shuttle (IOW I climb with it). There's only one place I've ever really noticed the limited wheel/bar turning, and that was easy to get around once I got used to it. I do need to think about my line a little farther down the trail than I was used to doing, but that's not a bad thing; I've probably gotten faster because of it.

I don't regret it at all, for what that's worth.

I've been thinking about this as well, i.e. Fox 40 @ 7" travel to balance out the ride. My 7 see's nothing but FR now, (i'm ditching the reverb to). I found the braking bumps/DH courses at Trestle put the Fox 160 well beyond its limit
