Well, this is two stock Bennett KPs in one month. I think that I'll just start swapping out KPs when I order new Bennetts. It is the same kind of break--right at the splines. Luckily, this time, I was only doing 12 mph and didn't hit my head.

Can you post a pic of the broken pin perhaps a few close ups of the break itself?

Thanks

Actually, it looks just LIKE the previous broken KP.

These are the original pics posted from the first KP. I remember someone else stating that they, too, (ah, alliteration) snapped a KP in the same spot on the splines.http://picasaweb.google.com/jamesdsimpson/Broken

Jim, that's pretty wicked you've managed to bust two of these already. I'm glad you're okay because KP breaks--falls can really suck. it's worth taking up Aikido just to learn to fall in those split-second crashes Neutral

i'm dying to see your pump technique on video, as well as knowing all the particulars of your setup and typical riding terrain. i know from experience that riding over any kind of "cattle guard" type structure or sidewalk cracks with regularity contributes, but there could be something entirely new at play here.

where your pins are snapping is not a big surprise, but the fact it's snapping with this much regularity is, not having yet broken a front Bennett yet. whenever I've busted or seen pins busted, it's always been where a compromise to the bolt is made -- either threading, splines, or an area where the hangar was able to grind into the pin repeatedly.

my strategy here would be to pop out the stock pin, replace it with a grade8 bolt of the same or just slightly shorter length, that has a smooth shaft from the head of the bolt to where the threads start. I would put the bolt through the plate just like the stock was mounted, and use JB Weld to hold the head in place, letting it set for an overnight or two, then mount up like normal. This would be somewhat like the method samhell has used, but I would lean toward keeping the bolt's head and smooth shaft end in the baseplate end. if this makes no sense, I'll try to snap a pic sometime later.

Yup, killed mine in the same place as well. right at the splines, below the level of the baseplate. Replaced with a 2.5 grade 8 and haven't had a problem since. I won't run another stock Bennett bolt in the front again. Wish the company had an email address or phone number. I can't even tell them there is an ongoing problem. Smile

Yeah, I tried that one too. I even asked JP to find me one. He couldn't get ahold of them at the time either. But thanks for the effort. Smile

I figured that you would have tried that one, but threw it up just in case.
