For anyone who's owned a Marzocchi lately...

With the new mag unified lowers, is there still really much of an effective stiffness difference between QR and 20mm thruaxle designs? Looking to possibly put one on a HT that will see both some trails/climbing and definitely DH/FR use...maybe a 04 Z1 SL.

Either that, or maybe the Manitou Nixon. Been really happy with my Shermans, so the Nixon with the TA and TPC+ is looking very appealing as a versatile fork, too. (although I'd have to go Rabie-style and peel off the horrendous metal plate decals on that thing...)

You can always run a BMX bolt-on axle with axle nuts instead of a QR, that gives you a more solid interface.

Comming off a shiver SC, my All Mountain 1 feels like the stiffest thing ever. It's definitely stiff enough for me, in the 130 or 150mm setting. The adjustments are just crazy, you can basically make it ride like a Z1 or Z150, ride as plush as a marzocchi or a little firmer to reduce brake dive and the such, lock it down with ETA, lock out it or simply "slow" it with TST, it's simply loaded with features, no spring changes necessary, etc.

All this, and the all mtn 1 is below 5lbs with a cut steerer (5.06lbs stock, amazing considering a 150mm fork weighed about 7lbs a few years ago). The coil nixon is only slightly heavier, but it only has 135mm of travel with the recall to keep it from slamming the tire into the crown.

The all mtn is amazing, it goes from feeling like a Z1 to feeling like I have a DH fork bolted to the front of my bike (150mm travel), it's not a big change in travel or geometry, but on the bike it feels like a huge change when you change the travel, and this fork easily excells in either travel setting. It's perfect on my foes FXR.

has anyone actually measured the clamping force generated by bmx axle nuts vs. a quality (shimano, salsa, hope, whatever) QR?

FYI (and yes, this is splitting hairs), the Nixon was reduced to 140mm instead of 135, and that's only for the first production forks made, starting sometime around mid november they're going to be going back up to 145mm.

:mumble: I WANT MY 5MM!!!!!

There's no comparrision, this is why BMX bikes use axle nuts and not QRs.

With a QR, there is simply not enough force to keep the wheel from slipping in the dropouts.

I think the bolt on axle VS QR debate really comes down to with a QR you are squeezing the fork against the hub with a 5mm skewer. With a bolt on you are pinching the the fork between two nuts on a 10mm axle. With a bolt on the only part of the axle that sees any stress is the area between the locknut on the hub and the outer nut you crank on to tighten the wheel, these few millimeters are in tension and the rest is unstressed. With a QR the entire skewer is in tension and the entire axle is in compression so imperfections in the material, processing defects and tolerances will have a bigger role in the actual performance of the system.

its more than the clamping force (or preload), its about the stiffness (axially, meaning stretching) of the QR rod vs solid axle. So say you have the preload of the axle vs QR exactly the same, the axle will still provide a stiffer setup, since it'll take a greater force to seperate the legs.

But will it go up against a Sicilian when DEATH is on the line?

where do you come up with this stuff? Did you buy a random quote generator from the Sharper Image or something?

It's my only defense against techno-babble and Internet ranting!

guess it beats trying to understand how and why stuff works the way it does.....

 

[MikeD]

I'm just kiddin', dude. Actually, I'm interested in it, and this is one of the few times the QR vs axlenut question has been addressed by people who I trust to know what they're talking about.

I think Korn was talking partially about my rant in the best steel HT thread, which was entirely quoted from Dr. Evil...anyhow, yeah, didn't mean to be hatin'.

I would like to hear from some more people who have ridden the forks I asked about, though, esp. because my front hub can't take a BMX axle. (although I suppose I do have an XR disc lurking somewhere in a corner of my dungeon...)

i dunno, i think your off my christmas card list this year.

its too bad, because i was going to use teeth whitening paper with inset hundred dollar bills this year...

Fine, you won't get a Channukah rock from me, either!

oh i get plenty of those, for some reason the Jewish kids in the neighbourhood hate my front window....

Of course, you take quotes out of movies that I disliked enough to forget everything about them except the name. Yeah you hit that nail on the head though.

If you can't find that hub in your dungeon I've got one I can hook ya up with.

Another product that increases stiffness on a QR is that setup from Ringle. Their front D-shaped hub with their bolt on axle,
and a Z1 lower, and it will be stiffer than Jm's stance on Boxxers.
