GS Astuto

If you are tired of city life, GS Astuto is the best place for you to have a countryside bike adventure. It has easy access to forest road, paved road and trails. I have been there many times but still the wonderful experience surprises me every time!

I got my titanium travel bike from Tim in 2012 and it has taken me 40,000kms or more since, including London-Edinburgh-London, Paris-Brest-Paris, Hokkaido 1200, Okayama 1200, Tour de Tasmania, etc.
Others have had a similarly good experiences. Whether it is wheels, a full bike, or just a rental/tour, highly recommend.

身長150cm、市販のロードバイクはどのメーカーの最小のものでも私には大きすぎ。バイクは我慢して乗るもの、と諦めかけていたところ、ティムさんを紹介して頂き、「妥協する必要なんてない！体にぴったりの自転車に乗るべきだよ！」と、650cのロードバイクを薦められ、最高の1台を組んで頂きました。カスタムメイドなので材質やパーツ、塗装も思いのまま、予算も含めいろいろと相談に乗ってくれます。出来上がった1台は私にはジャストサイズで取り回しも楽、クオリティが最高なのはもちろんアフターサービスも万全です。バイク選びに迷ったら、是非一度ご相談されることをおすすめします。

If you on the quest of seeking a comfortable perfect bike of your size, this is the only place you should go! Tim-san, the bike master is available for you, making one and only, perfect bike just for you. A new shop near mt. Myogi is also nice place to visit, surrounded by beautiful scenery and hill crime area. You can also rent a bike here, not only for sightseeing, but also might be a good idea to try his bike before you perchase.

GS Astute, reliable professional bike shop, definitely highly recommended!

川崎から拠点移す前に組んでもらったロードの定期チェックに日帰りで

車に積んで東京からひたすら関越道
途中道の駅甘楽で朝採り野菜と姉妹都市チェルタルドのワインとオリーブオイル買ってピザ窯で焼いたマルゲリータ食べてから向かい松井田妙義IC降りてすぐ

目印はユニオンジャックと窓の番猫
家の前の旧中山道を走り続けると軽井沢に着くらしいし富岡製糸場もすぐそこなので次回はゆっくり泊まりで

帰りに道の駅妙義で妙義山の大の字見ながらソフトクリーム食べて榛名湖で紅葉観て伊香保経由で帰路へ

春には改装も終わるそうだし
ホイールに拘る人は是非訪問すべき

I rented their gravel bike for Gran fond Myoko two years in a row, enjoyed and loved it so much! Personable and awesome services. Thank you for having us and showed us around always.

Tim is my go to guy for gravel bikes and anything bike! Warm, welcoming & so much good goodness. I just keep coming back for more!

The best men i meet in my life so smart helpful all foreign came to japan or living in japan need any help for bike go to tim don't go japanese shop they stupid and they don't help for nothing he fix my mtb bike wheel amazing i give 100star the best

Awesome service. I rented a bike from them for a bike climb to Mt Fuji from Kawaguchico. The bike was delivered and picked it up from my AirBnB.

Tim brought a sweet carbon bike with all I needed (helmet, cleats.), since I only brought my bib, jersey and bike computer with me. The Astoto SF99 was a solid bike and I enjoyed my 60 mile ride.

I also had a nice chat with Tim who was gracious enough to provide me with few tips about riding in the area.

Highly recommended.

If you want to ride bikes in Japan this is your place. Tim helped us organise our trip through japan by bike.

Delivered a high-performance bike, pre set to my bike fit and well equipped to my hotel in Tokyo. Gave me advice about the best routes to take and assisted me when I had an issue later. I will cycle in Japan next year and I will definitely book with GS Astuto again.
