What we ended up with was an off-the-shelf single-pivot and pull-style linkage design that did that job, but didn't do it that well. My design was shot down quickly, however, largely because I didn't have a clue what I was talking about but also because I spilled a bubble tea on my drawing and it got really smudged. I had originally envisioned a high-tech dual-link system, called High Pivot Virtual, that employed an idler pulley and, I believe not coincidentally, looks a lot like what Santa Cruz was investigating in their recent V10 development video.
The first Donut will always be special to me, but I'll be honest: we spent so much time thinking about the geometry that we kinda just phoned it in for the rear suspension. While the first Donut used a single-pivot layout, this bike gets a DW Link suspension system to control its 170mm of travel. And yes, of course our new geometry technology is patented.ĭepending on the chainstay setting, all that adds up to a similar wheelbase as the first bike, but it gets there via a much longer rear-center, a longer reach, and a steeper front end. Our proprietary and revolutionary 58-degree head angle is paired with the 83-degree seat angle that worked so well on the first bike, and we've also lengthed both ends there's a 525mm reach, a 600mm effective top tube, and three different chainstay settings that allow for a 460, 470, or 480mm rear end. That makes the new Donut the first mountain bike in history that's not as slack as its predecessor, marking a bold new leap forward in geometry technology that we're calling Turn Helper Concept. Okay, so we fell a little behind schedule and the new Donut is about a year late, give or take another twelve months and a couple of " spy shots," but have you seen the latest enduro bikes? The Donut might be overdue, and it might have even spawned some poor imitations, but it's still a decade ahead of everything else on the market, regardless of where they hide their cables or how high the pivots get.Īnd to be fair, at the end of the first video we did say that the next episode wouldn't be out until 2030, so we're still ahead of schedule in my books.Ĭhris Cocalis assembling the first Donut while admiring the best headtube badge in the business.Īfter nearly twenty minutes of intense discussions that saw our eyes go bloodshot and a dangerous amount of Fuego Takis eaten, we finally settled on making the head angle 2 degrees steeper. That was the easy part, though, with us spending the next two years trying to decide if we should paint the frame Obsidian Black, Sable Black, or maybe even get really wild and go with Onyx Black. I'm not joking it took only fifteen or twenty minutes to settle on some new numbers that made sense.
While other brands were drilling holes in headsets and throwing their entire development budget at e-bikes, we were working hard to perfect the new Donut's geometry, not exactly an overnight process. Or at least it feels that way, but smashing through paradigms doesn't happen overnight, people. If it feels like it's been five years since the first Donut debuted, that's because time has been moving slower since 2020. The new Donut employs our proprietary Turn Helper Concept, a revolutionary geometry technology that integrates a forward-thinking approach guaranteed to deliver a paradigm-shifting handling experience for the modern mountain biker in the modern world.
