Hello it’s so nice to be again.
Not that I’m complaining, thoughts you. For instance, simply earlier than leaving for trip I obtained a bundle from the Previous Spokes House in Vermont. Not solely did it comprise these scorching canine roasting tongs:

However much more extremely it was additionally replete with Biopace [pronounced “BEE-oh-pa-chay,” and make that Italian hand gesture while you say it] chainrings:

Usually talking, the one much less fascinating part than a Biopace chainring is a yellowed pie plate. Nevertheless, because the biking world is aware of, I’m an avid Biopace proponent:

And now that the Previous Spokes House has lastly divested themselves of theirs, this formally makes me the world’s foremost dwelling repository* of Biopace chainrings, and I can solely assume a field of yellowed pie plates will quickly observe.
*[I mean sure, noted Biopace proponent Sheldon Brown probably had more than I do, but I shouldn’t have to remind you he’s no longer alive.]
Then once more, on nearer inspection it seems among the Biopace chainrings are bogus, and are the truth is Sugino’s tackle the idea, which they referred to as “Cycloid:”

[Just another Cycloid dressed like a PNS.]
So will I be utilizing these Biopace (and Cycloid) chainrings? You guess I’ll! Granted, I’ve by no means used a Cycloid chainring, and rumor has it that if you happen to combine Cycloid and Biopace chainrings on the identical crank your joints will seize and your knees will explode–although personally I feel that’s a lie and I think there’s most likely a synergistic impact that may launch me into supersonic speeds.
By the way in which, 45 seconds of Web analysis reveals that apparently Cycloid remains to be a factor, since as everyone knows elliptical chainrings did wind up catching on in spite of everything:
I can not wait to Tremendous Hill Climb.
