Gravel bike for sale
Spring cleaning time, and this bike could use a good home! This was built as a prototype and show bike for Shimano, and was used to launch their GRX Ltd groupset at the 2022 Unbound expo. And, sad to say, it has never been ridden…… Built to fit me, at 5’9″ and 145lbs. The frameset features a truss fork and truss chainstays, with a small diameter seatmast for compliance at the saddle (adjustable height via an internal wedge seatpost). There are four bottle mounts and internally brazed bosses for a framebag. Shimano GRX Ltd 2×11 groupset with matching GRX carbon wheels.
If it looks like this might be a good fit for someone, let’s chat and make sure the right position can be achieved; I’ve included the geometry in the photos for reference.
Rob,
Very nice. I wish I were shorter! I see from the Geo chart that you use, as I do, a fairly long top tube / reach for your size – as well as drop. I hope you are able to find a buyer. I also wish I’d found you earlier in my life to build me a bike. Maybe never too late if my knees hold out. I’m now riding with a very strong 77 year old to remind me that there may be a lot of years left to cycle.
I wish you well.

Hi Kurt, it feels like if we just keep riding then we can keep riding!
Best, Rob.
I am guessing that the odd fork and seat stays create some suspension give without “mechanical” suspension?
I haven’t done enough empirical testing to provide data, but as triangulated structures front and rear, there is not detectable deflection when riding. The big tires provide the primary compliance, whilst the undersized seatmast allows for cantilevered flex at the saddle.
Hey Andrew, I just wanted to give my experience with truss forks. I find they don’t give compliance per se, but they really opened my eyes to how much a normal fork twists and flexes rearward during braking. I actually think it’s more noticeable a difference than what marginal compliance would do, as tires really are the far and away most substantial way to change compliance. Anyway, I really like them, you’ll have to feel the difference yourself.
Interested to know if this is still knocking about. I can’t really predict what sort of price point this would be floating at, especially after sitting unsold for 4 years and the groupset tech having moved on substantially.
Gorgeous frame. Let me know what sort of amount you were looking for and I’ll have a good think.
sending you a private message, thanks!
