Enthusiastic positive review for Unior's Crank Saver kit!
So, genius that I am, I managed to cross-thread a pedal on my brand new Emonda and stripped the hell out of the crank. Right-hand side, too. I pulled it all apart and the thread was just unsalvageable. I hemmed and hawed about ordering a new 105 crankset (about $150) versus the $250 repair kit, but I decided to go with the kit as it has enough coils to repair both cranks 10 times, so if I manage to jack up any of my bikes ever again I can fix them too.
It was tricky to turn the tap handle with a leg locked in extension with no weight bearing, but I managed it. Park Tool's excellent guide and Unior's video were very helpful as well. 15 sweaty minutes sitting on the ground later, my crank has beautiful new threads and a steel coil that won't strip from a pedal. It's beautiful. I dunno why Park Tool wouldn't make or recommend a kit because this came out awesome and I couldn't be happier, plus I have idiot insurance for the next time I mess it up!
Just wanted to put this out there as I searched the forum extensively when I was debating what to do. Can't wait to ride again!

...a cautionary note: It is not impossible to get the repair rethread started into the crank at an angle slightly off from 90*. Don't ask me how I know this. You're much better off pulling off the crank arm you want to repair, clamping it in a vise with soft, non-marring jaws, and accomplishing the boring out and rethreading portion of your repair in this more controllable environment. Also, when installing the threadsert that Unior uses, it doesn't hurt to use some Loctite to fix it in place.
