Lucky Penny – My Handmade 3Rensho Tribute Fixed Gear

Image

2

In the fall of 2015, I embarked on a project to build myself a fixed gear bicycle using a set of the famous 3Rensho Modeulo lugs.  The build is chronicled in this Bikeforums thread, where I kept a photo diary of the process.  At the time, I didn’t know this would be the last frame I’d build for several years.  I’ve been riding and loving this bike for years since then, but I never got around to photographing and writing about the finished product.  This is my favorite bike, and I finally have some great photos of it.  Read on to learn about the inspiration for the frame, the copper plating, and the build.

Restored 3Rensho Super Record Aero

I put this bike together in 2016, after I completed the restoration of the frame.  The restoration process is documented here.  The smaller of the two Super Record Aero frames sold quickly, but this larger one hung around for a while.  I came into possession of a Lotus Classique bicycle, which I stripped in order to build up this 3Rensho.

In addition to the stock Sugino and Suntour components, I added modern Tektro brake levers, and cork bar tape that was shellacked a dark brown.  I also added a 3Rensho pantographed stem I had at the time, to give it some extra flair.  It was sold soon afterwards.  I realized recently that I’d never published any photos of the built up bike, so click “Read More” to check out the full hi-res gallery after the jump.

The First Zunow Catalog: KYGM 1973

Last year I scored an original printing of Zunow’s first catalog from Yahoo JP Auctions. The catalog is for master builder Takeru Kageyama’s line of full-custom bicycles branded “KYGM” (pronounced “Gee-mu”).

It offers a window into the early days of the Zunow brand, when Kageyama-san was producing French-inspired randonneur, road, and touring bicycles. The catalog is in Japanese, which is a challenge for a non-speaker like myself. With the help of some translation tools and my experience with bikes & bike parts filling in the gaps, there are some interesting learnings to be had.

Modeulo Lugs: Yoshi Konno’s Gothic Masterpiece

Yoshi Konno, the visionary founder of 3Rensho, designed several bicycle lug sets over the twenty-year history of his company. His magnum opus was the Modeulo series, which incorporated traditional flourishes with a distinctly modern “aero” design sensibility to create a shape that still turns heads over thirty years after their introduction. Click “Continue Reading” below to learn more about the history and development of the Modeulo lug!

Vivalo Touring, Sportif and Road Bikes

I’ve always been fascinated by non-Keirin bikes built by Japanese frame builders who are famous for their track bikes. All of the most well-known builders of NJS track bikes began their careers in the late 1960s – early 1970s, when the bicycle touring craze was sweeping the world and Japan in particular. They apprenticed in shops that built road and touring bikes, and many of them built these kinds of bikes early in their careers. Touring and sportif bikes are often custom-made for clients, and are expected to include the kinds of beautiful details and high level of finish common with this kind of luxury item.

Shuichi Kusaka, the master builder behind the Vivalo brand, built a number of road, touring, and sportif customs. In the past 15 years, I have only seen a handful, and in this article I’ll be highlighting a few of these lovely bicycles. Read on to learn more!

3Rensho Rarities from the Cyclone Days

Have you ever seen a 3Rensho cyclocross bike? I had not, until I came across the bike pictured above, on auction at Yahoo JP auctions. I thought about throwing in a bid on it, but rather narrow-mindedly decided that a 3Rensho that doesn’t have the logo engraved into a seat stay cap or fork crown wasn’t a 3Rensho worth buying. Man, was I wrong! I regret it now, as I’ve come to learn that engraved logos do not a 3Rensho make.

I’ve been diving into the history of Cyclone LTD (the Yoshi Konno’s brand that later became 3Rensho) as I’ve been researching the provenance of the custom 3Rensho Super Record I recently restored. In the course of that research, I’ve dug up a few interesting rarities to share. Read on to learn more!

This 3Rensho Cyclone is one of the rarest and most valuable bikes I have ever restored over the past sixteen years of collecting vintage bicycles. The story began for me on the docks of Red Hook, Brooklyn, but the story of this bicycle goes back much further in time. After extensive research, I’ve confirmed it was made by Mr. Koichi Yamaguchi in 1978 for the NYC Bike Show. This article relates the story of how it came into my hands, the restoration process, and some 3Rensho history. All images in the article are hi-resolution – click them to view the large version. Read on to learn more and check out the gallery of photos.
