The GRV is a no-holds-barred drop bar bike. It can go wherever you point it. Pavement. Gravel. Whatever. Take the road less traveled. Hell. Where you’re going, there may not even be roads. A strong will and a trace of hope that a connection can be made are the only other things you’ll need.
This bike is specially suited for coarse roads as it employs my FlyBy design. It’s different than a traditional double diamond bike frame because the seatstays bypass the seat tube and connect directly into the top tube. The top tube also incorporates a short section of curved tube. These two traits, the stays and the curved tube, effectively decouple the seat tube, allowing a small degree of deflection along the length of the tube. It works when the rider is pedaling in the saddle and the bike hits a bump with force great enough that the rider's weight on the lever, the seatpost, can cause a rearward movement on the seat tube as the curved top tube, the spring, is forced to extend a tiny amount.
The FlyBy design provides a greater degree of comfort during seated pedaling, and there is otherwise no detriment to the performance of the bike. It's very good on cobbled roads and over other sharp edged features such as exposed roots. It’s perfect for long days in the saddle when you know that the road (or otherwise!) could potentially be tough going.
The GRV can accommodate 40mm tires even with a short 420mm chainstay. It can be built around a carbon thru-axle fork or with a custom, steel segmented fork as shown. Head tube options (34mm/44mm) are specified to suit fork steerer dimensions.
