If you’re wondering why both forks use 15mm, rather than 20mm, axles, it’s because 20mm axles don’t necessarily make for a stiffer fork. It’s the enormous clamping force the axle provides (equivalent to about 5 metric tons), pressing the legs against the hub, that provides stiffness to the system.
the best part came next tho...(DH Forum closes ANSYS to go get pitchforks and torches)
Yeah, the fox seems decent, if you can get the steerer pressed in straight...also, the damping curve is pretty wacky according to Vorsprung.I was gonna go with a Zeb for the weight savings, but that sounds like a sucker’s move (according to this author, of course)
Wait, I thought there should be no high clamping forces otherwise the hub bearings would bind and die in no time???(DH Forum closes ANSYS to go get pitchforks and torches)

No, hubs are not designed such that bearing races can pinch closer under load and bind up.Wait, I thought there should be no high clamping forces otherwise the hub bearings would bind and die in no time???
That's what Cannondale should have called the Lefty.I really don’t want a fork named “The Gimp”...
Could a freeze spray through the steerer help shrink it a bit?I looked at that, seems like it'd be damn near impossible to get the locktite in there. I'm still considering it, but we'll see. I'd like to stretch it out for at least another few months, but I may go to the bike park tomorrow too.
It depends a lot on the hub and is statically indeterminate, but the primary load path from clamping down should go through the hub axle, some additional load will go to the bearings depending on how much the hub axle compresses under that load.Wait, I thought there should be no high clamping forces otherwise the hub bearings would bind and die in no time???
As those forks are heavier it is probably not a 1:1 comparison. The axle area may be stiffer, but so was the rest of the fork. Perhaps back to back testing with the same fork with the switchable axle sizes would be the most enlightening.Go ride a 15mm 36 and and then a 20mm one directly after it on an off camber rooty track- if you can't feel a difference go sell your bike. I rode a '19 36 for the last 18 months and then made a return to a 20mm one this summer thanks to @buckoW and did a direct comparison ride on my home trail in completely similar conditions. The difference in line holding ability over off camber roots was just impressive. I just don't get it why Fox doesn't use it on every 36 and 38.
On fancy road wheels (e.g. Vision), where you can adjust bearing play with preloaders, they recommend adjusting the wheels while clamped in the frame.It depends a lot on the hub and is statically indeterminate, but the primary load path from clamping down should go through the hub axle, some additional load will go to the bearings depending on how much the hub axle compresses under that load.
Supposedly, the Lyrik is already a lot stiffer than the 36. Fox is kind of known for using dinky small crowns, so that may have something to do with it, vs. on the 38 they finally stiffened it up some compared to the 36.I'm wondering about that fore/aft stiffness.
RS only wanted to increase it by 2% over the Lyric, whereas Fox increased it a hell of a lot more. So that seems like a plus right? But what if RS only had to increase it by 2% to get close to where the 38 is now?
I'd think heating up the crown would be more effective, the aluminum crown is wrapping around the steerer and has a much greater circumference due to this, so due to it's rate of expansion, it should open up more. But perhaps a combination of packing the steerer with some ice or something and trying to heat the crown, I dunno. My usual trick for headset cups is put them in the freezer and heat up the head-tube with a hair-drier, then the cups go in pretty easy.That's what Cannondale should have called the Lefty.

That makes sense. Wonder if I could do that to finely center my brake rotors?On fancy road wheels (e.g. Vision), where you can adjust bearing play with preloaders, they recommend adjusting the wheels while clamped in the frame.
Both are 2019 36 Grip2 Factory 170 models, one a 650b and the other a 29" one. Guess which is which...As those forks are heavier it is probably not a 1:1 comparison.

That's makes way more sense.Supposedly, the Lyrik is already a lot stiffer than the 36. Fox is kind of known for using dinky small crowns, so that may have something to do with it, vs. on the 38 they finally stiffened it up some compared to the 36.
If you had to pick one fork, which one would it be?I've got time on both, and the Zeb feels a little stiffer overall (especially torsionally) than the 38. Midstroke support from the Zeb isn't as firm as I'd like it to be, but small bump sensitivity is really good. I'm still fiddling with settings on the 38, but the compression damping adjustment range is surprisingly narrow, and pretty light.
Have you tried this?That makes sense. Wonder if I could do that to finely center my brake rotors?
Its not that it's whacky its just that the hsc doesn't do much.Yeah, the fox seems decent, if you can get the steerer pressed in straight...also, the damping curve is pretty wacky according to Vorsprung.
According to Schwalbe, or according to the direction it makes sense for the side knobs to be angled?Is that tire on backwards?
AXS garage door opener, duh. I already told it on Vital.New generation ZEB? looks like new lowers with air pressure release buttons like on the FOX 38.

AXS ShockWiz?What’s that thing on top?
Roger Roger...I'm just seeing how many decades I can get out of that question in relation to schwalbe tires.
Because it still cracks me up. It's like the airplane movie. It's never NOT funny.
The one he's going to be a dick about?If you had to pick one fork, which one would it be?
