Seths Pool Posted May 26, 2019 Share Posted May 26, 2019 (edited) Angekfire 2019 season opener- Awesome. the trails, so good my DH bike, not so good. Look at this shit! Landed off a jump and heard a loud snap. Thought I broke my frame and looked down to the shock just hanging in two piece. 2018 (new warranty replacement last August) Fox RC4 coil with 500lb spring. The Kashima inner shaft snapped in half! 🙄😳 2444F168-A6AA-4D4E-A8D4-796DEA9436A2.MOV Edited May 26, 2019 by Seths Pool Quote Link to comment Share on other sites More sharing options...
mack_turtle Posted May 26, 2019 Share Posted May 26, 2019 It would not surprise me if you are the first person to break a bike in this way. 1 Quote Link to comment Share on other sites More sharing options...
AustinBike Posted May 26, 2019 Share Posted May 26, 2019 Will a DHX Air 5.0 fit that frame? If so, ping me. Quote Link to comment Share on other sites More sharing options...

Seths Pool Posted May 27, 2019 Author Share Posted May 27, 2019 Pulled out 4th place/37 in open men at the angelfire 5 DH Race this weekend. Missed 3rd by .8 seconds. Bittersweet. Awesome time! 11 Quote Link to comment Share on other sites More sharing options...

RidingAgain Posted May 27, 2019 Share Posted May 27, 2019 On snapping things... Does this look fake? Just seems a little too clean... https://www.singletracks.com/blog/mtb-videos/watch-mountain-bikers-handlebar-snaps-mid-air/?fbclid=IwAR3IRzBRdZ1dCMcnidfsth4-tHtLp7iyTigmhzOzXVs4a7eqIdm-uL1SXDc Quote Link to comment Share on other sites More sharing options...
Nando Posted May 27, 2019 Share Posted May 27, 2019 You should seriously consider approaching some of these bike makers and offer your “factory pilot“ services Quote Link to comment Share on other sites More sharing options...
Seths Pool Posted May 28, 2019 Author Share Posted May 28, 2019 Just spoke to pivot- “Bikes with a suspension yoke - aka “wishbone linkage”, particularly the longer travel bikes such as the Pheonix DH bike and firebird are not recommended for coil shocks as the yoke puts heavy loads laterally on the rear shock which can cause failure” apparently it’s a “blurb” mentioned somewhere on their website. I haven’t looked for that statement yet though. So a big heads up for any of you running a coil on your bikes with a yoke/wishbone linkage system. I’m assuming this applies to bikes with simlar linkage designs outside of the pivot brand Quote Link to comment Share on other sites More sharing options...

Tree Magnet Posted May 28, 2019 Share Posted May 28, 2019 I suspect every bike manufacturer out there has a 'Buckner' clause hidden somewhere in their website. I believe this isn't the 'Has anyone every broken....?' thread that he's started. Quote Link to comment Share on other sites More sharing options...

I read it to mean that the shock would fail which is exactly what happened. What I don't totally understand is why it wouldn't also destroy an air shock? The same lateral loads exist but is the air shock just supposed to absorb these loads differently? Also, not recommending a coil shock on a DH bike sounds like BS. Is this just saying that no one should be running coil shocks on bikes with a suspension involving a yoke?

Also, not recommending a coil shock on a DH bike sounds like BS. Is this just saying that no one should be running coil shocks on bikes with a suspension involving a yoke? so the main shaft of a coil shock is a metal rod about 1/2" in diameter. essentially, the lateral rigidity and structural integrity all depends on that little shaft. that 1/2" diameter shaft isnt going to dissipate lateral loads and forces as well as the air shaft of an X2 air shock which is probably 1 1/2 - 2" in diameter. I just thought these bike manufacturers and engineers would be making these frames and linkages to provide all the stiffness independently from the shock being involved to help with stiffness.. since thats not why the shock is there. but that do I know. apparently this also voids the fox warranty. but I am now seeing that this is on their website - Quote Link to comment Share on other sites More sharing options...
Teamsloan Posted May 29, 2019 Share Posted May 29, 2019 Not only are many frames not designed to protect the shock from loads like this, but many have leverage ratios that are not designed for the linear spring rate of a coil and will actually blow through the travel too quickly. Some frame manufacturers are responding to the increasing trend of coil shocks and designing bikes with leverage ratios that will work for them or air shocks.Sorry you found out about all this the hard way!Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
ATXZJ Posted May 29, 2019 Share Posted May 29, 2019 (edited) Kona offered a coil for the yoke driven linkage on the 167 when it was first released. They also dropped it the following year. I have only read of one guy breaking a coil the same as Seth on the 167, and it was an xfusion. That design does sideload a bit as even the airshocks seemed to have seal issues.

AlienSP Posted June 21, 2019 Share Posted June 21, 2019 Really nice bike and stealth graphics. Running a Fox Float X2? I love the adjustability of that shock. Got one on my Switchblade. Quote Link to comment Share on other sites More sharing options...
