What an animal!....

Is it the Allen head thats stripped and not the internal threads into the shock?

If so get a dremel with a cutting disc and carefully cut a slot that you can use a flat head screwdriver in. That will get you going until you sort replacements with Troydon.

Side note. Trunion shocks are a terrible idea. In fact, blind threaded bosses are plain stupid when they can be avoided and standard bolts used. Thats a backwards step for Crestline.

Was hoping I could get one local or overnighted. If I have to wait for Crestline it will be a while. Not stoked on not riding.

Another dodgy option that could work is to get the next size up torx bit and hammer it in and undo, redo it up with that.

PS, No second bike? If one of my bikes isnt going i just pull the next one down and ride.........
 
Third, 4th and 5th options before using the first two options. There are some tapered allen head keys that can sometimes work when a standard one doesn't. If not available file down the next size up allen key into a tappered one and try that.

Next option there is a graphite type gripping compound you cant buy that helps grip worn screw heads ect, find some of that and try it. Its kind of like valve grinding paste.

I sold my "2nd" bike a few weeks ago and have a 181.2 arriving in 3-4 weeks. Bad timing. I might try your solution so I can still ride.

Take the other side out (non stripped bolt) and bring to your lbs and see if they can match it. Quick internet search seems like it might be a relatively standard trunnion bolt. If there’s an issue getting the stripped one out buy a good quality ez out bit, irwin makes good stuff.
 
Glad you got it out. I was going to suggest the torx trick too. If that didn’t work I would have suggested a stripped/brocken bolt extraction bit. And if that doesn’t work then you break out the dremel.

I absolutely hate aluminum bolts. It’s way too soft for Hardwear. Allen head especially regardless of the material. Torx are better but they still strip on occasion. Especially with some of the half sizes. Another really stupid option too.

Having said all that, if you strip an aluminum bolts/screw it’s better than stripping the insert threads.

I stripped some Aluminum hardware on my Ripmo and had to cut it off then use a tap to clean the steel threads back. 5 years going strong on that fix.

Yeah, and blind bosses are freaken stupid too. Those damn trunion shocks are a recipe for disaster. They are fiddly as fuck to get the fastener in and cross threading could happen real easy. Then you have screwed ya shock too.

It's one of my criteria of buying bikes. No trunion shock. Stupid, stupid.

That bolt is soft and tolerances seemed not great from the start. Mine is starting to round/has play after maybe 5-6 uses. Yes, I've used a torque wrench.
 
Glad I managed to get the bolt out. There were plenty of cuss words along the way, haha. I actually got lucky—while backing it out with an easy-out, the drill slipped and caught the bolt just right, which let me back it all the way out.
