Well, here's more fodder for the group.
From time to time, I've caught the bottom of my jeans in my chainring, even though I wear an ankle strap.
Unfortunately, there isn't much available in the way of chainring guards.
I did look at the Kool Stop Chain Disk, but it wasn't what I wanted.
So, I bought a 52T chainring off ebay for $9.99 and custom fit it to my 44-32-22 crankset.
With this setup there is no interference with the derailleur shifting to all three chainrings.
And I personally think it looks better than some plastic disc.
And it works great.
Oh, and for those who are curious about the grey PVC.
That's my DIY fool-proof chain jump stop.
No more granny gear chain hops.
