3Rensho XR-7000 Lo-Pro Pursuit Funny Bike

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!

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 let’s 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!

3Resho Super Record Export Aero Road Frames – Complete Restorations

bluerensho1

In 2014, I acquired two San Rensho (also written as 3Rensho; “san” is Japanese for “three”) road frames.  One, pictured above, was a 53cm and the other 58cm.  While they came from different sources, they were both Super Record Export versions.  3Rensho, which translates to “triple victory,” was a highly regarded bicycle manufacturer from Japan in the 1970’s-90’s.

Founded by Yoshi Konno in 1974, 3Rensho bikes were made by a team of Konno, Koichi Yamaguchi, and Masahiko Makino.  While 3Rensho made both road and track bikes, they are most widely known for their track bikes which were custom made for Japan’s Keirin racing sport.  Tragically, in 1995 Konno was responsible for a drunken car crash that killed five people and left him paralyzed from the neck down.  3Rensho closed down shortly thereafter.

Despite this ignoble end for one of Japan’s most prestigious bicycle brands, Yamaguchi and Makino went on to great success building frames under their own names.  Yamaguchi has made frames for the U.S. Olympic Team, and continues to make custom frames as well as running his own frame building school in Colorado.  In addition, Cherubim Bicycles, founded by Yoshi’s brother Hitoshi, continues to create amazing bicycles under his nephew Shinichi Konno.
