I'm letting go of my Rosco Bubbe from the 2022 batch. This is functionally essentially a Platypus frame as far as geometry, functionality and ride goes. It differs in that it is mostly tig welded, but is still a beautiful frame as to be expected with Rivendell! I am selling the complete bike for $2000. Cash on pickup in Cincinnati, Ohio, or buyer can arrange and pay for a local bike shop to pack and ship.

It's in very good condition with just a small scratch on the top downtube (see picture). I am selling it as pictured except I am keeping the saddle and Choco handlebars and Nitto stem for my Sam. There will be a Uno Advanced Project Adjustable Stem (31.8 mm) included. I am also keeping the bottle cages, rear rack, bags, bell, lights, computer, and SeatyLock that are in some of the pictures.

Most of the pictures show it with a Microshift Sword 2x11 setup with 31/48 chainrings and a 11-42 cassette. I have it currently set up as a 1x11 with a 42 Microshift Sword chainring (shown in last picture). Included will be the original Microshift front derailleur, thumb shifter and chainrings to easily convert it back to a 2x11 if desired.

It may be a little confusing between the pictures from various stages of experimentation and my description as to what is included, so below is a detailed list of exactly what you will get:

-Drivetrain: Microshift Sword FC-G7000-48 1x11 with 42 chainring and 11-42 Cassette. Also included are the original 31/48 chainrings (not currently mounted with 1x11 setup)

-Derailleurs: Shimano Deore rear and Shimano Altus front (not currently mounted with 1x11 setup)

-Shifters: Microshift 11 speed rear and 2x front (not currently mounted with 1x11 setup) thumbshifters

-Brakes: Tektro V-Brakes with Tektro Eclipse levers

-Pedals: State platform pedals

-Wheels: Velocity Cliffhanger rims, Shimano hubs, Soma Shikora tires

-Headset: Velo Orange

-Stem: Uno Advanced Project Adjustable Stem (31.8 mm)

-Seatpost: Uno Advanced Project

-Bottom Bracket: Shimano

Worth it for the head tube badge alone! 
Seriously, best badge going and a nice frame too.

Hi Chuck, 

I thank you for letting me know the make and model of your handlebar bag. I appreciate it. 

It is strange to see that the bag appears larger than it does. I have the same Ornot handlebar bag in white, blue and black. Your handlebars might be more narrower than mine. I have the Nitto Bosco Aluminum HT 58cm handlebars. 

Kim Hetzel.

As an alternative, I can arrange for packing and shipping within the CONUS for $2200.

Gotten a few nibbles but no commitments, so how about $1850 for the bike and you pick up in Cincinnati or arrange shipping (I can suggest local bike shops), or $2050 shipped to your door in the CONUS.

Picture of it configured how it will be sold. Only things not in the picture that you will also get are the two chainrings and the front derailleur and shifter from the original 2x setup.
