Destroyed on Impact!
Was doing a few test drops in prep for a 7 stair jump. First drop went ok, but on the second one, all H### broke loose...to the tune of SIX BUSTED SPOKES! Lesson learned: Not a good idea to do biggish drops on a uni with a *Disc brake Hub*! They are narrower so the disc can fit, making it weaker than a regular, wider hub, which distributes impact to a wider area. Found out the hard way! Who knows, maybe it's an omen, telling me that people almost 61 should stop doing this stuff while they're still in one piece? ^_^

At some point the things we used to do become silly in hindsight.
But it's your hind to be silly with, if you so choose.

It seems like the feature you have blamed is not related to the problem that you have experienced!

I don't think the problem is the disk brake, I think the problem is the GoPro, Ask yourself this question, "If I didn't have a GoPro, would I be riding my unicycle off a loading dock?" But hey, at least you aren't parkouring off of rooftops.

Too much punishment for the parts. Though with spokes snapping it makes me wonder if it was the hub's fault.
Keep on riding, and push the limits as much as you want. No use listening to the people who don't appreciate your passion.

Yea, the Go Pro. No more "hey bubba hold my beer" to your one or two close by friends, but you don't even need someone watching anymore.

Off road Unis sometimes Have to lock up the wheel and Bounce over stuff.. a trials Technique..
A 20" or 24 x 4 fat wheel uni would be more forgiving..

Pretty damn stupid to be doing this at the age of 61. You should wait until you are at least 65 so Medicare will kick in and pay your medical bills. I'm 50 and with a $6,500 deductible, I don't dare do anything that could land me in the hospital. I can't wait for Medicare!

You just need the correct wheel, not a disc wheel that's dished to make room for the rotor. Oh, and 72 spokes and 4" tires wouldn't hurt either if you're going to do drops like that.

I've done so many drops, and many bigger than that without spoke breakage, but I usually use my 24" wheel with Large marge 65mm rim with non-disc hub, and Duro 3.0 width mountain tire. That uni is bullet proof and stays true no matter what I throw at it. This was the first - and last - time trying bigger drops on a 26er, with disc hub, which makes the wheel weaker in this respect, as I found out. 
The other factor contributing to the failure, at least with this uni set up, was dropping to flat concrete, without a down slope to roll out and distribute impact. But when doing a stair drop, there's more speed and momentum, so even though you land on flat, the forward momentum helps to give you a good roll out.
