Hey Dave, it's been a minute. I'll jump in for sec with a quick thought. At first I was with @Mitch's zzz's. I mean, the trouble with over analyzing is that you better not skip over any contributing factor. It's easy to miss the target. Trying to pen out a calculated comparison seems in vain...
Any takers for used dust masks? Beggars shant be choosers. Barely any asbestos.
I hope I'm not too late to the party. I'm somewhat of an occasional pedestrian through this mill.
Dave, I was wondering if you would eventually run into skipping problems, but not this soon. Here are a few thoughts:
-Your chain "snapping off" both front and rear rings almost sounds like you could have a tight link in your chain. Possibly from an install?
-I would def run stainless or Ti...
The damage seems inconsequential.. but for liability sake o_O If you're interested in a Non-marred 1-1/8" steerer 29" fork - I have an old Reba with old standard QR dropouts and an Xfusion with a 15mm thu axle.
$50?
If interested DM me and we can work out details.
