This is the third season of our custom collaboration series with CHAMPION. Thanks to your support, it has been a huge hit, becoming a popular item in both Tokyo and Nagoya. For this spring and summer, we are bringing you a message from Circles on a heavy-ounce T-shirt that is perfect for everyday wear.

Nerds recognize nerds.
I can say this with conviction: in any field or genre, the coolest people are the nerds.
I remember "nerd" being used as a derogatory term before 2000, but in this day and age, being a nerd is cool.

It is a title that can only be earned by those who love a culture so deeply that they have fully embraced it.
In any era, truly cool people always swim against the tide.

In an age where information is overflowing and everything is easily accessible, there exists a "digger" style that defies the internet metaphor of the "cloud" by daring to dig deep into the ground locally. Nerds are no longer just a cluster; they have become a distinct species.

In our industry, this species is known as the "Bike Nerd."

Circles is home to many such Bike Nerds, and their knowledge and experience are what give this shop its distinct character.

Yes, the bicycle industry is kept in motion by the devotion of these Bike Nerds.
This T-shirt is a tribute to the Bike Nerds we admire so much.
With 200% respect, we hope for the day when all of humanity can become bike nerds.

If that happens, the world will surely be filled with love and peace.
About the Body
The T-shirt body is made by CHAMPION. It is a short-sleeve tee with a dry touch, crafted from 100% sustainable American cotton produced with the environment in mind.
It features a relaxed fit with CHAMPION’s signature "Action Style" sizing—a slightly shorter length to balance the wider body and sleeve width. Thanks to the product-wash process, it has a lived-in feel from the moment you put it on.
