NEW! Esker Cycles Introduces the Walden Ti

Esker Cycles introduces the Walden Ti fat bike.  Following their entry into Titanium with the popular Japhy Ti and Hayduke Ti models, Esker is bringing out the Walden fat bike in the wonder metal, with the Portage Dropout, refined geometry, and excellent ride quality that all Esker models are known for. 

“At Esker, we strive to make products that last, and give people the best possible ride” said Tim Krueger, Esker Cycles CEO.  “We use steel and titanium for our hardtail bike models because of the excellent ride characteristics and extreme durability of both materials.”

The Walden Ti is hitting the market first in Titanium.  Also known for having very well riding, refined geometry that most people say “immediately feels like home”, this new Esker fatty should provide buttery smooth comfort to ride far, far out there. 

“We’ve always been known for having really well sorted geometry that just feels like home” added Krueger. “In my career, I was part of the team that brought the world the first production complete fat bike and the first production complete gravel bike.  I’ve been building and riding these sort of bikes for a long, long time, and really honing in on perfection.”

Walden Ti
