Just released, the Esker Lorax Ti is a new titanium gravel bike based on the discontinued steel Advocate Lorax, and the Esker Walden Ti is the company’s new titanium fat bike. Find the specifications and details on both models here…

Following Esker Cycles’ foray into titanium with space metal versions of their Japhy and Hayduke hardtails, they just expanded this lineup to include a new titanium gravel bike and fat bike. Both feature 3al/2.5v Titanium tubing, adjustable Portage-style dropouts, refined geometry, and the ride quality and durability that titanium is known for. More on both below…

Esker Walden Ti

The Esker Walden Ti is an all-new titanium fat bike. Esker describes it as having neutral geometry that works equally as well on soft snow and sand as it does on high-speed hard pack terrain. The frame has three-pack mounts on both sides of the down tube, full bolt-on frame bag mounts, and a standard bottle mount on the seat tube. The Walden Ti can fit up to 27.5×4.5″ or 26×4.8″ tires, has internal dropper post routing, and is designed around a rigid 490mm fork or a 120mm travel suspension fork. The Walden Ti is made from double butted, cold shaped 3al/2.5v Titanium and uses Esker’s proprietary, adjustable Portage Dropout System.

Esker Lorax Ti

Bringing back the old Advocate Lorax gravel platform, the Esker Lorax Ti is their new titanium gravel bike. With generous tire clearance and a versatile geometry, Esker claims it’s the perfect bike for “gravel paths, forest roads, and occasionally dipping your toes into singletrack.” The Lorax Ti features full bolt-on frame bag mounts, three-pack mounts, full fender and rack mounts, internal dropper post routing, and can fit up to 29×2.0″ tires. Like the Walden Ti, the Lorax Ti is made from double butted, cold shaped 3al/2.5v Titanium and uses Esker’s Portage Dropout System.
