GR20 Bowyer Blue Number 15
When James from Bowyer Engineering handed me a business card for inspiration for his GR20 custom gravel bike build I knew we’d be able to do his long standing family engineering company proud.
James’ GR20 features Shimano GRX mechanical groupset, 20 degree flared bars, 650b Mason/Hunt wheels with Hutchinson Touareg tyres with 80ml of Stans sealant in each. This is his “hooligan mode” setup.
Colour is corporate RAL5003 Royal Blue with hologram graphics for some flare without being too bold. We did look at chrome silver reflective and even made up the graphics pack but weren’t happy with them so abandoned the idea. Graphics layout is “alternative” with custom Bowyer at the front of the top tube. Size and placement of this was very important as it’s a bold logo.
James has also chosen a second set of wheels for winter training and road riding in general. These still offer off road flexibility should he fancy it. He has a set of Hunt 4 Season Gravel Disc X Wide 700c wrapped in Hutchinson Overide Tyres in size 700x35c. They’re running Ultegra Rotorsn and he stores them in a matching Hunt bag when not in use to keep them safe.
Weight is 9.2kg as pictured with the 650b wheels on.
