Sig. Rando (Frame & Fork Set) | A Modern Randonneur for Freely Traveling Japan's Roads

From city riding to camp touring. A modern all-road randonneur born for Japan's road conditions.

Smoothly cruising along paved roads on your trip, then turning down an intriguing side road to explore. The "Sig. Rando," crafted by Hiroshima-based bike shop Grumpy, was created for enjoying such freedom in cycling.

While inheriting the philosophy of traditional randonneurs, it has been redesigned to suit modern riding styles. With ample clearance for wide tires and numerous eyelets, it accommodates a wide range of uses, from city riding and long-distance touring to bikepacking.

Furthermore, it features a convertible design that supports three wheel sizes: 26-inch, 650B, and 700C. The flexibility to change the ride feel according to the season, travel style, and load capacity is also a major appeal.

The appeal of Rando lies in its versatility, not being overly specialized for a single purpose. It performs as a comfortable all-road bike for commuting and daily use, and transforms into a touring bike for camping trips on weekends.

The supple ride quality characteristic of chromoly reduces fatigue during long rides, and its stability when loaded with luggage is excellent. Since you can switch wheel sizes and grow with it over time, it's also recommended for those who want to customize a single bike to their liking.

Even if your travel style changes, it adapts its character to match. The Sig. Rando is a frame with such profound versatility, designed for enjoying Japan's roads.
