If you're looking for a bicycle that you can ride daily without much fuss, and that you'll find yourself reaching for most often, then the BROTHER CYCLES ALLDAY is a very straightforward answer.

With the simplicity of a single-speed, the gentle ride quality of a chromoly frame, and geometry that's easy to handle in the city, this isn't a bike designed to compete on speed or flashiness. Instead, it has "just the right completeness" that naturally makes everyday commutes and detours more enjoyable.

This time, we're introducing an original complete bike that maximizes the appeal of the ALLDAY frame, built from eirin's perspective as a "tool for daily use."

Let's explain, step by step, why the ALLDAY is a "bike you'll want to ride every day."

This is an original complete bike, re-imagined from eirin's perspective as a "tool for daily use," built around the "ALLDAY" single-speed frame from London-based bike brand BROTHER CYCLES.

About the ALLDAY Frame

The ALLDAY is a single-speed frame designed with a strong focus on daily use, while retaining the simplicity derived from track bikes.

It features cantilever and V-brake mounts, as well as eyelets for front and rear fenders and racks, making it incredibly versatile despite being a single-speed.
Its design philosophy emphasizes continuous, natural use in everyday life, rather than showcasing "speed" or "stoicism."

The oversized chromoly frame isn't overly stiff, offering a smooth and gentle ride.
While not flashy, it possesses the solid "tool-like quality" that allows for a long-lasting relationship.

Concept of the Original Complete Bike

This ALLDAY is an eirin original complete bike built with the clear goal of becoming the "bike you find yourself riding most often," while maximizing the frame's appeal.

It's not a "special bike" adorned with high-end parts, but rather a configuration focused on being naturally chosen for everyday commutes, detours, and errands.

This philosophy is clearly reflected in the component selection.

For tires, we've opted for FAIRWEATHER for CX tire by CG (700x32C).
They offer a good balance of light rolling and a sense of security, not too narrow for mostly paved roads, and a size that allows you to ride confidently even on rough surfaces or uneven urban terrain.

Precisely because it's a simple single-speed setup, the tire choice prioritizes "rolling smoothly on any surface."

The crankset is a SUGINO XD2.
While not flashy, it's highly regarded for its stiffness and durability when pedaling, and it's less likely to go out of adjustment even with rough daily use – truly a "tool-oriented" crankset.

Additionally, a DIXNA chain guard is installed to reduce the stress of soiled pant cuffs and chain issues, which are inevitable with daily use.

The handlebars are RITCHEY NEO CLASSIC with a short reach.
While utilizing the operability and stability of drop handlebars, we've set a position that prevents an overly aggressive lean.

No component was chosen "to stand out"; instead, the criterion was whether it would accumulate stress over long-term use.

This ALLDAY is not a finished product the moment it's assembled.
We believe it's a bike that, through daily use, accumulation of minor scratches, and familiarization, approaches its ideal form for each rider.

Design and Ride Quality for Daily Use

The BB drop of 60mm, a slightly higher design, allows for responsive acceleration in urban areas with frequent stops and starts.
This geometry is also well-suited for urban rides like the grid-like streets of Kyoto.

The front center isn't excessively short, which means your toes are less likely to hit the front wheel, providing reassuring handling for city riding.

Furthermore, the frame's interior is rust-proofed, a subtle touch typical of BROTHER CYCLES, reflecting their consideration for riding in the rain and everyday use.

Combining the lightness unique to a single-speed with the gentle ride quality of a chromoly frame,
this bike offers a natural sensation of "riding without a second thought."

Summary | The Reason You'll End Up Riding This One So Often

The ALLDAY is not a bike for special occasions. Rather, it's the bike you naturally reach for on days with no plans, no specific destination, or when you simply feel like going outside.

Easy to ride, easy to handle, and timeless. It doesn't make a flashy statement, but it's reliably trustworthy in everyday life.

A bicycle that meets these criteria will, as a result, become "your most frequently ridden companion."

The BROTHER CYCLES ALLDAY quietly blends into the rhythm of your life, making the very act of riding a bicycle a little more comfortable.
