Strangely and coincidentally, this afternoon eBay sent me a notice of
items that might interest me, and there it was: a "Buy-it-Now" Miche 48 x 135 x 1/8 track 'ring at Ride-This.
My thanks to all of you who went looking through your stuff for me. Or plan to soon. I am\u2014temporarily anyway\u2014replete in the chainring area.

PS: I've been buying stuff from Ride-This for some time and I recommend them, they're good guys. I just forgot to check their copious listings this time. You'll probably do that too, when you reach my age.
