Nagasawa Special NJS Track with Suntour Superbe Pro

In December of 2021 I wrote about a Nagasawa track bike I restored.  It was actually my second Nagasawa; this article is about my first one.  I acquired it in early 2017 as a lucky eBay find; only $800 complete!  Based on the serial number, it was made in 1984, and I think it had been repainted at least once in its life, since the paint was in excellent condition.  It was built up with cheap parts which I quickly discarded, opting instead for an all-Suntour Superbe Pro track build.  I also had an additional challenge: I don’t ride brakeless fixed in the streets, but I also did not want to defile one of Nagasawa-san’s forks by drilling it for a brake.  Instead, I purchased a fork from a different NJS bike that had already been drilled, and which used the same fork crown and dropouts as the Nagasawa.  I acquired new decals and sent it off to Allan Wanta, who did a marvelous job matching the pearlescent yellow paint of the original.  Read on for more info on the build, plus a cool interview with Nagasawa-san from 1983!

3Rensho Modeulo Katana Road

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 Litage Aluminum Complete Build


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!

Italian Steel in the Eighties: The Gios Compact

The Gios Compact debuted in 1986, and has since been considered by cyclists and collectors to be one of the best frames Gios ever produced. The most revolutionary technical innovation introduced by the Gios Compact was its adjustable dropout system.  The wheelbase can be lengthened or shortened by 8mm, to create an aggressive hill-climber or a more sedate roadie, depending on the terrain and the rider’s preference.  This example from 1987 was recently restored in my shop with a period-correct mix of Shimano Dura Ace and 600 components.  Read on to learn more about the Gios Compact and the Gios story.

Nagasawa Special NJS Track with Dura Ace 7500

The Nagasawa marque sits at the apex of Japanese Kierin bicycles, recognized worldwide for impeccably designed and executed frames, each hand made by master builder Yoshiaki Nagasawa. This particular Nagasawa, built in May of 1985, came to me as a frameset by way of Yahoo JP auctions. It has a 53cm seat tube (center-to-top) and a 54cm top tube (center-to-center). It has a beautiful, but hard to photograph deep green / blue paint scheme with rainbow sparkles and yellow highlights. I built it up with a period-appropriate Shimano Dura Ace track group set. Read on to learn more about this bike and the back-story of Nagasawa bicycles.

59cm IRO Mark V

Another IRO Mark V rebuild / repaint project.  I love building up and selling these bikes, as they are one of the most solid, no-nonsense urban single-speed / fixed gear bikes out there.  They have the perfect geometry for city streets, and use high-quality steel in the frame construction.  For a fixed-gear under $500, it beats all challengers.

I got this frame as part of a trade, and I overhauled and refinished it.  Dismantled, cleaned out, and re-packed the headset and bottom bracket, added some shiny new silver deep-V’s, a Fuji Feather saddle, and a new cockpit with front & rear brakes with nifty pink housing.  Crankset is a Sugino RD 170mm with a 48-tooth Rocket chain ring, 16 tooth Dura Ace cog, KMC K710 chain, and MKS Stream track pedals.
