DAMN Riders - No rules, Just ride!

Rather than drilling a stud into the knob, they run a tapcon (hard cement screw) from the inside out. Then, they zip a ¼” nut on the outside. You have to line the inside to protect the tube from the screw heads but an old inner-tube works. One guy said he doesn’t even use the nuts as the liner and air pressure keep the screw in place but I would prefer the nut if it were me.

To me the advantage of this is you are not relying on the threads to hold the stud in the knob and it is secured both ways by the head and the nut. For $75 bucks worth of screws and a day in the garage I am would be inclined to try this, I already got plenty of old tires lying around. And plenty of extra blood in my system I didn’t have a lot of time to fully investigate how long this setup holds up; but I am sure the nay-sayers will be along to shortly…

But seriously, I think you could do this faster and cheaper getting a bunch of long #8 or #10 PK screws (self tapping sheet medal screw for you commoners) and running them through the knob from the inside. I'd be willing to bet $5 worth of screws, two Makita batteries, a 12 pack and one blood transfusion would get the job done. PK screws have the advantage of having a smooth head, lees chance to tear a tube and running them from the inside would prevent leaving spike strips on the trails. Heck, I've got a worn out tire, and a day to myself, maybe I'll get some screws and give it to Jay to try (No way am I loosing all my carefully hoarded blood mounting that thing on my bike.

How's your silencer/chain/swingarm clearance? Those side screws definitely look wide enough that I'd be replacing a silencer.
