3Rensho Modeulo Katana Road

Posted on by

This is my “personal” 3Rensho, the one I bought specifically for myself and have spared no expense to restore.  As the article title states, this is a “Modeulo Katana” model, likely from the late 80s / early 1990s.  It has the signature lugs, webbed bottom bracket, 3Rensho “SuperEnds” dropouts, and the same aero fork crown as also seen on my handmade tribute pista.  The straight fork blades are a clue to dating its age, as it is likely inspired by the Colnago “Precisa” straight fork that strongly influenced bikes of the period. It’s built up with a mix of 8-speed Shimano Dura Ace 7400 and 7410 components, with about half of the parts original to bike.

Custom 3Rensho Cranks by La Vie Velo Classique

3Rensho pantograph (and photo) by La Vie Velo Classique

When you’re so close to perfection on a classic bike build, how do you “take it to the next level”?  The answer, my friends, are pantographed parts.  These are components that are custom engraved using a pantograph milling machine.  Usually the brand name of the bicycle is engraved, although sometimes a bicycle owner will also have their own name added.  It’s considered a “lost art” nowadays, making it nearly impossible to get new parts engraved.  Vintage examples are usually expensive, often costing two to four times the price of the same component without engraving.  Parts engraved with rare marques like 3Rensho command astronomical prices when they appear on the market.

That’s why I’m excited to have discovered La Vie Velo Classique!  Based in Hungary, master craftsman Ábrahám Zsolt uses a traditional pantograph machine to create new and beautiful works of art for vintage bicycles.  He recently made the above 3Rensho pantographed crank set for me, and I was blown away with the finished results.  The quality of his work is absolutely top-notch, and indistinguishable from original vintage examples.  Read on to learn more about La Vie Velo Classique and the lost art of “panto parts”.

3Rensho XR-7000

After three years, I finally finished my restoration and build of this 53cm 3Rensho XR-7000 bike.  I acquired it from Japan as a frameset, and discovered it was made under license  by Yamakuni.  Check out this prior article for the history and background.  I had the fork re-chromed, but left the main triangle as-is.  I bought a barely-used Georgina Terry Despatch from 1988, and stripped it for the 6-speed Suntour Cyclone 7000 groupset and the 24″ front / 700c rear wheelset.  I’m aware the 3Rensho catalog showed it built with a Shimano 600 group, but they also sold it as a frameset.  Cyclone was Suntour’s second-best group in the same way that 600 was a notch below Dura Ace.

The rear Araya rim had a crack in it, so I re-laced the hub to a brand new Araya RC-540 rim.  The stem is a NITTO S65 Crystal Fellow with NITTO RB-021 bullhorn handlebars, matched to the NITTO S66 seat post.  The 3Rensho saddle finishes off the build in style.  Read on for more photos and ride report!

A couple of months ago, I wrote a 3-part series on the subject of 3Rensho’s various forays into aluminum bicycles.  Their earliest product remains their most well-known, a collaboration with Sakae Ringyo to sell their Litage aluminum bike under the 3Rensho brand.  You can learn all about them in this article.  Today’s entry is a brief update to show off the finish build of the 3Rensho Litage I restored.  Read on for more details and photos!

3Rensho Carbon Bikes – SR, Aegis, and Araya

In my last two articles I showed how 3Rensho, a brand synonymous with the finest handmade steel bicycles, added aluminum bicycles to their lineup thanks to third-party manufacturers like SR and Yamakuni.  Now I’d like to take a deep dive into an even more esoteric corner of the 3Rensho story: carbon bikes.  This time around I am relying more than ever on 3Rensho’s catalogs, as it’s been extremely hard for me to find examples of these bikes in the “real world” that have been photographed and shared online.  I’ve identified three models so far: the SR Litage with carbon tubes, and two monocoque designs from Aegis/BIK and Araya.  Read on to learn more!

3Rensho Aluminum Bikes – Part Two: Yamakuni

Translation: “With a basic weight of 8.9kg, the 7000 series aluminum frame produces the lightness and stiffness required for racing.”

In the early 1990s, TIG-welding was rapidly eclipsing the “screwed and glued” method of aluminum bicycle frame construction. At the same time, aluminum frames were enjoying peak popularity among professional racers, being ridden to victories in the Tour de France and other major events.  This was the era of stiff, lightweight aluminum race bikes with extra-skinny tires, and 3Rensho was not going to be left behind.  Enter the Yamakuni 7000 bicycles, which would replace the SR Litage in the final years of 3Rensho.  Before we get there, let’s dig into a brief history of welded aluminum frames after the jump.

3Rensho Aluminum Bikes – Part One: SR Litage

In this multi-part series of articles, I’m going to explore one of the more obscure corners of the 3Rensho story: aluminum-framed bikes.  The 3Rensho brand is generally associated with steel-framed bikes of the highest quality, often hand-made and utilizing proprietary lug designs that make then instantly identifiable.  However, from time-to-time, aluminum frames with 3Rensho logos surface in online sales or fan pages.  This typically leads to a rambling debate about whether they are “legitimate” 3Renshos and who manufactured them.  I can say with 100% certainty that they are legitimate, as they appear in multiple 3Rensho catalogs that I’ll share here, as well as shedding some light on their background.

In this first part of the series, I’ll focus on the most common aluminum 3Rensho: the Sakae Ringyo Litage.  Read on for more info and photos!
