The Yasujiro Ultra’s frameset showcases JapaneseJapanese Steel classic bicycle design from Japan craftsmanship through full Tange Prestige tubing and lugged construction, effectively bridging the golden age of chromoly with today’s performance demands. After Yasujiro Tange founded his legendary tubing company in 1920, his family now honors him with a bicycle embodying everything their name represents.

Tange Prestige Cr-Mo Tubeset and Lugged Frame Construction

The Yasujiro Ultra’s frameset utilizes premium Tange Prestige Japan chromoly steel tubes, which offer exceptional strength-to-weight ratios. Furthermore, the lugged construction method provides superior joint strength while maintaining the classic aesthetic that steel enthusiasts cherish. Key specifications include:

  • Frame weight: 2170g (size 52cm with fork)
  • Traditional 1″ head tube diameter
  • BSA threaded bottom bracket shell
  • 39-49mm brake reach compatibility

Additionally, the lugged joints distribute stress more evenly than welded connections, thereby increasing longevity. For maintaining these precision steel tubes, the Park Tool FR-5.2 Cassette Lockring Tool with 5mm Guide Pin proves invaluable for routine maintenance, especially when servicing the BSA bottom bracket threads that define this classic frameset design.

Campagnolo Potenza 11-Speed Drivetrain Integration

The complete Campagnolo Potenza groupset delivers precise shifting through its Power Shift Ergopower levers, consequently providing seamless gear transitions. The drivetrain configuration optimizes versatility with these components:

  • 50×34 compact crankset (Tange T-6030)
  • 11-32T Campagnolo Chorus cassette
  • Front and rear Potenza derailleurs
  • 2×11 speed setup for 22 total gear combinations

Moreover, the wide-range gearing accommodates both climbing and flat terrain effectively. The Pedro’s Pig Pen II Bicycle Chain Cleaner works perfectly with the Campagnolo chain, thus ensuring the drivetrain maintains its smooth operation throughout thousands of miles on this steel machine.

Fork Design and Front-End Component Stack

The Tange Prestige chromoly fork complements the main triangle perfectly, therefore creating cohesive ride characteristics throughout the bicycle. The traditional front-end setup features:

  • Tange Seiki 1″ threaded headset
  • T-5330 stem with -17° angle
  • 26mm bar bore specification
  • T-4244 drop handlebars
  • Alhonga 43-57mm silver brake calipers

Subsequently, this classic cockpit configuration provides multiple hand positions for long-distance comfort. The highly-rated Park Tool HCW-16.3 Chain Whip and Pedal Wrench becomes essential when adjusting the threaded headset, which requires periodic maintenance on this traditional steel setup.

Wheel System and Contact Point Specifications
