SimWorks making things for any spaces of in between. . . Nature and society remind us how much we still don’t know.

-Imagination & Creation of your life quality-

Human beings have lost many things so far that cannot be regained completely. We’ve noticed that the same thing is happening in our precious bicycle world. There was once a time when bicycles were locally built by hand welding together tubings — maybe those bikes were used by our own grandparents. Commute and transport relied heavily on bikes.Japan ev

entually became the most important place for bike manufacturing especially when people around the world started using bikes more recreationally. Times are different now.Manufacturing centers are found in other countries while companies in Japan receive their ideas and products massively without any hesitation. Has the Japanese bicycle industry lost not only their production power but imagination as well? We’ve realized that the reason is based on a lack of understanding through consumption. A radically different market can be seen here in Japan if we tap into our roots: make products by our own hands, increase lines on communication, and use the knowledge that we do have. Simworks has begun taking action to change the system against the trend of mass production. Our goal is to give our clients the highest quality of product and in the end life! We think it is necessary in order to guide the next generation. This is what we stand for and this is our passion we’d like to share with you.

Finally got to visit Allez LA!

私にとってはGSC/ GSC permently closed, but never fogotten. がクローズして以来のLA訪問。ようやくこのお店を訪れることができました。

つい1ヶ月ほど前にオールドロケーションから移転したばかりというお店には、GSCの頃を思い出させるような宝物がちらばっていながらも、今まさに新しく蒔いた種がこれからしっかりと実ろうとしている最中です。

広くなった店内ではセールス・メカニックスタッフみんながフル稼働で忙しくしていて、何より心配だったという空調もしっかり効いていて快適そのもの。

久しぶりの再会はもちろん、新しい出会いもあり、やっぱりGSCでも彼らの強気であったそのコミュニティーハブとしての求心力の強さを改めて垣間見ることができました。

This was my first visit to LA since GSC closed. I was finally able to stop by this shop.

The shop, which had just moved from its old location about a month ago, was dotted with treasures that reminded me of the GSC days, yet it’s also in the midst of seeing the seeds it’s just sown begin to bear fruit.

In the expanded store, the sales and mechanic staff were all hard at work, and—most importantly—the air conditioning, which had been their biggest concern, was working perfectly, making the atmosphere incredibly comfortable.

Not only did we reconnect with old friends, but we also met new people. Once again, We got a glimpse of the strong centripetal force they’ve always had as a community hub—just as they did back at GSC.

Our good friend モレンド・マハラニ and ARI visited Nagoya.🤝

インドネシアのお友達のモレンドとアリが名古屋に遊びに来てくれました。

元々は以前Circles Tokyoのライドに参加してくれたのがきっかけで知り合ったのですが、Doppo Roninに乗ってインドネシアで色んなライドを楽しんでいるモレンドと、SURLY Grapplerに乗るアリの二人はインドネシアのライドコミュニティーを牽引する中心人物。

他にも様々な旅行の計画がある中で名古屋に来る時間を作ってくれたので、ライドや名古屋グルメでしっかりおもてなし。ちょうど名古屋の酷暑が猛威を振るいだしたタイミングでしたが、楽しんでくれたようで何より。二人ともありがとう!次は我々がインドネシアに行く番ですね!

Our friends from Indonesia, Morendo and Ari, came to visit us in Nagoya.

We originally met when they joined a Circles Tokyo ride a while back. Morendo, who rides a Doppo Ronin and enjoys all kinds of rides in Indonesia, and Ali, who rides a SURLY Grappler, are both key figures leading the Indonesian cycling community.

Even though they had various other travel plans, they made time to visit Nagoya, so we made sure to treat them to some great rides and Nagoya’s local delicacies. It happened to be right when Nagoya’s sweltering heat was at its worst, but we are glad they seemed to enjoy themselves—that’s what matters most. Thank you both! Next time, it’s our turn to visit Indonesia!

【Re-Stock】TOMII CYCLES x SIMWORKS Faraway Tire

TOMII CYCLESのナオさんによる「トレッドのサイドにサボテン、キャニオン、ムーン。いつかアリゾナの砂漠にこのタイヤの跡を残せたら....」というアイデアを載せたトレッドに、SimWorksが誇るPanaracerの製造技術を融合したFarawayタイヤは、高反発弾性のナチュラルラバーをベースにした耐摩耗性と耐久性に優れたコンパウンドを採用。

Farawayはトレースをするためのタイヤじゃない。
進んだ道を正解にしていくためのタイヤだと思う。
引き返してもいいし、寄り道をしてもいいのだろう。
いま走っているその道を、自分のものにしていけばいい。

「遠くまで走りたくなるバイク」にふさわしい、走りと美意識を兼ね備えた一本です。

The Faraway tire—which combines SimWorks’ renowned Panaracer manufacturing technology with a tread design inspired by an idea from Nao of TOMII CYCLES (“Cactus, canyons, and the moon on the sidewalls of the tread. Someday, I hope to leave the tracks of this tire in the Arizona desert...”)—features a compound based on high-resilience natural rubber that offers excellent wear resistance and durability.

Faraway isn't a tire for following trails. It's a tire for turning the paths you've taken into the right ones. You can turn back if you want, or take a detour. All you need to do is make the road you're on your own.

These tires combine excellent performance with aesthetic appeal, making them the perfect choice for a “bike that makes you want to ride far.”

SimWorks × NANGA “Sleeping Capsule”

An ultralight 260g bikepacking sleeping bag that fits perfectly into a 1L Nalgene bottle: SimWorks × NANGA “Sleeping Capsule”

We co-developed our ideal sleeping bag with NANGA ( ), a premier down manufacturer based in Shiga, Japan. Outdoor enthusiasts are likely already familiar with their exceptional quality—they are a leading Japanese brand that has earned the absolute trust of mountaineers challenging the harshest environments.

The "Sleeping Capsule" utilizes NANGA's signature UDD (Ultra Water Repellent) down. Because the feathers themselves repel water, the sleeping bag won't lose its loft even in humid bivouac conditions or heavy night dew, keeping you reliably warm.

We took this high-performance down, distilled it to the essential functions needed for bikepacking and outdoor play, and designed a long, slender stuff sack specifically for easy loading on a bike. Furthermore, we engineered it to fit seamlessly inside a 1L Nalgene bottle for completely waterproof transport!

Rooted in the UL hiking philosophy of lightening your load to expand the possibilities of play, let's head out for freer, more adventurous rides!

わずか260gで1ℓナルゲンボトルに収まるバイクパッキング用寝袋 SimWorks × NANGA “Sleeping Capsule”

理想の寝袋は、滋賀にあるダウンメーカー「NANGA(ナンガ)」と一緒に開発しました。アウトドア好きなら、その品質の高さをご存知かと思いますが、過酷な環境に挑む登山家たちからも絶大な信頼を集める日本を代表するメーカーです。

「Sleeping Capsule」には、ナンガの真骨頂とも言えるUDD(超撥水加工)ダウンを採用しています。羽毛そのものが水を弾くため、夜露や湿気の多いビバーク環境でもシュラフがへたらず、しっかりと暖かさをキープしてくれます。

その高性能なダウンを使用し、バイクパッキングや遊びのために必要な機能に濃縮し、さらに自転車へ積載するための細長いスタッフサックに収め、完全防水で運搬するためナルゲンボトルにも収まるように設計しました。

[ SimWorks × NANGA ] “Sleeping Capsule”

For the sleep between the rides. 🌙
Introducing the SimWorks × NANGA “Sleeping Capsule”

Sleep is a crucial element for bikepacking and adventure rides. Reflecting on countless journeys, we partnered with Japan’s premier down manufacturer, NANGA, to create the ideal sleeping bag designed specifically for cyclists.

Designed for spring and autumn touring (approx. 7-20°C / 45-68°F), we boldly stripped away the non-essentials. By removing the zipper and hood, focusing only on "resting the body," we achieved an ultra-lightweight class of just 260g.

The biggest feature is its packability on a bike.
The slender stuff sack is designed not just for frames and forks, but to fit perfectly into a standard water bottle cage! Furthermore, it can be packed into a 1-liter Nalgene bottle, offering a unique and completely waterproof packing solution even when riding in the rain. 💧🚴‍♂️

Ride until you're exhausted, take a quick deep sleep, and ride again.
From fast-paced bikepacking adventures to a "just-in-case" layer for summer nights, this sleeping capsule will quietly expand the freedom of your journey.

走る合間の、眠りのために。🌙
SimWorks × NANGA “Sleeping Capsule”

自転車を使ったアドベンチャーライドやバイクパッキングにおいて、睡眠は大切な要素。これまでの数々のライドを振り返り、旅と睡眠の道具である「寝袋」の理想の形を求めて、日本のダウンメーカー「NANGA」の協力を得て作られたのがこの「Sleeping Capsule」です。

春と秋のツーリング(およそ7〜20℃)を想定し、機能を思いきって割り切り。ジッパーやフードを省き「体を休める」機能だけを残すことで、寝袋としては最軽量クラスのわずか260gを実現。

最大のポイントは「自転車への積載方法」。
細長い専用の収納袋はフレームやフォークだけでなく、ボトルケージにぴったり収まるサイズ!さらに、1リットルのナルゲンボトルにも収納可能なため、雨天時でも完全防水のパッキングがユニークに解決します。

疲れ果てるまで走って、少し横になり泥のように眠って、また走り出す。
そんな極限の旅から、「念のため」のお守り装備や、遊びの道具として。あなたの旅の自由度を静かに広げる、新しいライド感覚の道具です。
