Pinkbike Academy Season 1 winner and Enduro World Cup racer, Evan Wall, has signed with Haro Bikes to develop two new prototype frames. Based exclusively on a mixed-wheeled setup and Horst-link suspension design, the 160mm-travel "Greer" is still in the prototype stage, although it already looks like a solid enduro race machine.
The geometry for the size large frame doesn't stray far from the new normal for bikes in this category. Based on a 170mm travel fork, The head tube angle sits at 64 degrees while the seat tube lands at 78 degrees. Short 435mm chainstays produce a wheelbase of 1273mm.
Evan will be the sole member of the team and will be tackling a full EDR schedule, competing at two Crankworx stops; Innsbruck and Whistler, as well as the mass start Mountain of Hell race. Along with a change of frame sponsors, Ekoi, Vee Tire Co. and Classified Cycling are major shifts in his program.
Recently, Evan debuted the prototype in multiple races at Sea Otter where he appreciated the versatility of the Horst-link design. He admits after coming off of a bike with a high-pivot suspension design, the Greer plays to his weaknesses on flatter tracks, versus adding to his strengths in rough terrain. You can bet he's been putting the Greer through the paces around Squamish.
| The most unique thing on my bike at the moment is the Classified system I’d say. It’s pretty cool to be testing out some new tech. So far it’s been working great, and I’m stoked to get to use it in real life, racing scenarios.—Evan Wall |

| I'd say I’m most particular about my brakes. I’ll notice right away if the bite point or position is slightly different, and it’s something that I have a hard time compensating for.—Evan Wall |
A WTB Volt saddle sits on a 175mm Kashima-coated Fox Transfer post which is slammed in the frame.
| I went with number 54 for jersey and bike. It’s the number my Dad had on his car when I went to the track with him as a kid.—Evan Wall |
Looks like they aligned the outer face of the main pivot with the outer face of the BB. That's the typical design choice because it's easy and safe, but there will always be additional space available to the chainring and inner face of the non-drive crank. I always recommend to my clients that they get CAD models from as many crank manufacturers as possible (these are readily available to CAD drafters in the industry) and push the main pivot width beyond the BB faces.
We may see some high-end frame brands struggle to differentiate their human-powered products. Until recently, it was largely about geometry, kinematics, and weight. The former two are starting to plateau and we're not as worried about the latter as we used to be. Some have pursued aesthetics and are attempting to make their frames look like Apple products with smooth lines, hidden fasteners, hidden / electronic control hardware, and integrated bars, stems, and seatposts. Some have pursued suspension function via active dampers or indirect (high-pivot) drivetrains. Maybe we'll see a broader spectrum of mechanical assistance - a smooth continuum of offerings from current high-powered boost down to, say, 50 W of boost from a system that adds only 2 lb.
The point is that a decreasing portion of the advances are strictly from the frame, as frames like this leave little room for major improvement in the human-powered, telescoping fork bike chassis. The maturation of a product is a good thing, but not a very exciting thing!
My current big bike is not unlike this one, chunky aluminium and four-bar suspension but with more progressive geo. I genuinely don't expect to replace it for 10 years.
Say wut?
Evan was thinking along the same lines and mentioned the team might experiment with a 10-speed setup soon.
@mariomtblt: Split pivot is definitely not Horst!
It would be possible to remove that mechanism from the hub and place it at the BB, meaning the chain would still move when coasting - as has been done before. If we're going to do that and move some gears in there, we might as well move all the gears in there and eliminate both the cassette and derailleur at the rear wheel.
... and we just made a gearbox.
Good luck this year Evan!
I feel like I've watched as 20 years of Haro prototypes have popped up and the Walmart level bikes are tall that are ever released.
It gets me thinking, is there a reason enduro racers aren’t rocking a Pinion?
Who knows...
For MTB every other manufacturer moved to 30mm and BSA is not a good fit. Having T47/ 386 evo would be way better and not a problem for 24mm spindles anyways.
Please Haro differentiate your frames by keeping the "short" chainstays, and please steepen the actual seat tube =)
