Bianchi CX + A Sheldon Brownian Eccentricity

Just wanted to drop in and show you a neat little trick.

At first this winter beater seems very normal.
A Tange Prestige Bianchi CX... single speeded.



If you zoom in on the front brake, though...



Well it's a cantilever converted to a v-brake !
I got inspired a few years ago by this page on Sheldon Brown's site



It works reaaaaally well and looks very nerdy.

RIP Sheldon Brown !!!

Actually Sheldon made a typo in his page.
It's a rare find, a World Class V-Dapter
From time to time a pair will pop on eBay.

Why would you want to? Just for the hell of it? (That's a perfectly good answer, BTW)

You know how you see those homebrewed projects where the bike has one gear pedaling forward and a different gear pedaling backwards? I think those work via two freewheels that ratchet in opposite directions. One of those backwards ones might do the job.

For fixed gear, left side drive creates a self-tightening -- rather than the usual self-loosening -- action during deceleration. It's actually not a bad idea. Yes, I know, the lockring is supposed to keep the cog in place, but a rear brake and left side drive would make the system about foolproof.

Sheldon was the best. He always responded cordially to my emails, and I was fortunate to get to meet him and take a tour of Harris about 10 years ago, while on a business trip to Boston. Shortly thereafter MS began to take its toll.

Retro direct bikes actually have two freewheels mounted In the same direction. Hence why they propel the bike forwards regardless of the pedaling direction.

And if the OP had a disc rear wheel, he/she could always get a 6-bolt on cog and run it fixed without worry of lockrings.

It's made for rear luggage racks, but I hacked it into that. So far so good, but winter will tell how well it works. In the mean time I have to find a better solution for the back. Those Ass Savers really don't cover anything.
