Grytstone Titanium Frameset
Grytstone Titanium Frameset
The Grytstone is our flagship titanium bike. It’s an adventurer, a wanderer, suitable for multi-day epic bikepacking trips, or even pedaling to the store. Whether big tires or small, drop bars, or flats, it’s a true, do it all rig. While we use lightweight titanium in its construction, we designed the frame to address the needs of larger riders and the ability to carry more gear.
Important - We quickly sold through the first order of framesets, and the next order for the Medium/Large/Extra Large frames is to be delivered in late 2023
Extra Small and Small frames go on sale in late 2023 for delivery mid-winter 2024
The pre-order price saves you $250 off the regular retail price and includes free shipping. And pre-order closes October 31st 2022. All customers will be contacted to confirm specifications, upgrades, etc. before the closing of the presale.
