New odyssey stampy video

I Think the biggest question is;
Did you use the "Bikeguide, I hold you forever true" code when buying the forks from Empire?

--- Quote from: skateparkrider on December 15, 2014, 10:17:51 PM ---I was stoked to see another Stampy test.  But was bummed it was another fork test.  I was hoping for something else, but I understand the reasoning for the second go at forks. 

Also..... this could be a little bit of the Coors Lite talking here.....  but C'MON!!!  Don't you feel responsible in the slightest bit to let people know what BMX products are designed in an inferior/dangerous way????  I know that sometimes you can stir up the shit pot too much to the point where you might fall in and then be covered in shit.....  So I do get it on one hand.  But on the other... at least you can get out of the shit pot, take a shower and not smell like shit after a few days.  Everybody else would be forever smelling of the stench that is doo doo.

Yep, we agonised about this, but BMX is way too small a pond to start taking a big dump in the middle...

The standard "industry" test setup for forks is: +-650N, with force set perpendicular to the fork, <25HZ, 100.000 cycles. Immagine attaching the front wheel to the wall, then pressing and pulling (only with 65kgs), few times a second, 100K cycles. Any entry level mtb 5us$ fork made of cheap steel should pass this test. Make no sense to test bmx forks this way.

Odsy setup looks good. Stampy jig with build resonable headagle, and force direction like real landings. Resonable 500-600kgs force. Love it.

G, it still weird to see so many competition forks snapped clean at the steertube. In real life I see them cracked mostly at the welds e.g. blades/steertube junction or sometimes dropouts. Not too many snapped steertubes around for the last few years. I hope the new forks are not too light/too thin in this critical point.

One more... G, I think I see different frequencies used [0:50-1:10]. I dont think the video is speed up... I'm guessing only. ?

dude...:
^^^^ yeah it is interesting where they broke. most of the time, ive seen forks break at the welds on the dropouts, or where the legs are welded to the steerer. ironically ive seen a couple of sets of old odyssey forks break off clean through the steerer, although i think it could have been due to a stray ball bearing from the headset rubbing between the steerer and headtube (there was deep grooving).

id like to see a test that puts vertical forces on the fork legs and dropouts as i think this is probably what causes failure the majority of the time from the impact of harsh landings, and right now also from smashing onto the peg for grinds. its gotta be hard to simulate actual riding forces though because theres sideways loads as well and a combination of forces coming from all directions, especially in the case of say an big 360 down some stairs
