Now Finished: Fox Factory Ask Us Anything
Did you ever consider doing an adjustable offset on the 40? (Like with a couple different axle bore locations)

Review: Atomik's BERD XC33 Wheels Use Spokes That Look Like String
Exactly! How am I supposed to jump my bike over the campfire after a few beers with these?

[Updated] Video: Aaron Gwin Teases New Downhill Bike
Hopefully something with more aggressive rearward travel and a sneaky idler just above the chainring :)

Great concept, but you went way too far with the HTA

Field Test: 2020 Rocky Mountain Slayer Carbon 90 - The One That Broke
@mountainsofsussex: spot on! I too never really considered the importance of the dropout dimensions and manufacturing accuracy until reading your comment. I wish pb would’ve posted more photos of the dropouts and hub cause I’m curious if they show any signs or wear or misalignment etc. I am tempted to show these pictures to the guys in our inspection lab and metallurgy lab here at work to see what they have to say (I work in automotive engineering and we deal with broken shafts/axles/etc like this all the time). With all that being said, and I do largely agree with your theory, it still seems possible to me that the pivot went first. Maybe not completely even, but maybe just cracked/deformed or even just flexed enough to give the axle/hub/dropout some misalignment which then lead to the axle failure. The whole pivot system could have a number of flaws, improperly pressed bearings, out of spec bearing seat, or even an over torqued pivot axle. One issue I see with a lot of these modern axle designs is that they do not utilize any sort of pinch bolt to hold the axle in place. Pinch bolts (such as on a fox 40 for example) are great because minimal torque on the axle itself is required, and the the pinch bolts hold it in place without needing to have a huge tension load in the axle itself. On top of that, you really never need to worry about an axle coming loose on you. I know they just got rid of them for simplicity for the consumer and manufacturing, but they do serve a good purpose. Either way, I know rocky will have the exact cause of this figured out quickly with today’s high tech inspection equipment and other metallurgical inspection, and I’m excited to see what comes of this.
