The Shredmaster is a High Pivot, 29er, Gearbox Downhill Bike That Takes a Water Bottle

by James Smurthwaite  

What do you do when you're stuck in hospital with tonsillitis and nothing to do? For most of us, it would probably involve buckets of ice cream and watching shreddits, but for Andi Jakoubek from Munich, it was the perfect opportunity to design his dream bike. Unable to find the 29er downhill bike to fit his 6'4" frame at an affordable price and high on a fever and antibiotics, Andi got inspired and, 18 months later, the Shredmaster was born.

Andi has no background in the bike industry, beyond 17 years of riding, but he's a graduated Pinkbike armchair engineer and avid reader of linkagedesign.blogspot.com.
Shredmaster Details

Frame Material: 7020 aluminum
Intended Use: Downhill
Wheelsize: 29 inch front and rear
Transmission: Pinion 6 speed gearbox
Head Angle: 63°
Reach: 500mm
Sizes: 1, custom
Weight: 17.5kg without pedals
Price: N/A
More info: @project_shredmaster

He combined this with a drizzling of inspiration from the 77 Designs Kavenz project and got to work dreaming up kinematics and linkages. It wasn't long before he'd roped in Peter, a high school friend and engineer for a German car manufacturer, to help him with the finer points of the design and the project started to take shape.


There were a few key points that Andi and Peter wanted to bake into the design to create their perfect bike. First, it had to have a high pivot design to allow for a rearward axle path, an idler pulley to eliminate pedal kickback and a leverage ratio that was progressive enough for a coil shock but not too progressive that it would sacrifice mid-stroke support. The bike also had to be aluminum as carbon was too expensive and the weight and aesthetics of steel were not to their liking. These aluminum tubes also had to be straight for simplicity and strength. Finally, the bike had to have adjustable geometry to switch between a regular 29er and a mullet set up.

The linkage is driven by this one-piece machined rocker that was glass pearl blasted and black anodized.

The frame is designed to be as low maintenance as possible with tapered roller bearings at the main pivots with an additional rubber seal preventing ingress of water and dirt.

The adjustable geometry added a lot of complication to the design process with Linkage-Design files for each specific flip-chip setting, but it was worth it to experiment with mullet set ups.

The Gearbox

Andi and Peter admit that the final product does bear a more than passing resemblance to a GT Fury but there's one huge difference, the Pinion C1.6 gearbox. This provides six speeds, which they believe to be enough for a downhill bike. When asked about the added weight, Andi said, "1kg on my DH bike doesn’t really bother me. As far as I know, there is a whopping 2kg difference just in frame weight between a Supreme and a Gambler, and both frames are winning World Cups and I would love to ride them… So long story short, I don’t care.

He continues, "You save 450g of unsprung mass on the rear wheel, since the derailleur and cassette are gone. And since 'suspension performance first' is my agenda, that is a killer argument pro gearbox. Also, the weight sits perfectly low in the bike, giving a super planted feel. The ratio of unsprung to sprung mass further improves, so let’s just say the suspension should work really well. I can also remember Orange fiddling with extra weights to achieve this."

The Pinion housing is also machined from a solid block.

As for the drag of the gearbox, Andi compares it to running a chain guide on his regular downhill bike and he and Peter have also designed a custom chain tensioner with a sealed spring that reduces the drag of the standard box. Currently, the gearbox uses a grip shift but is soon to be replaced by a trigger shifter designed by "another nerdy soul from the IBC-Forum."


Geometry

The frame is designed around Andi's 6'4" proportions but smaller versions are being worked on too (more on that below).

The Chainstays


The chainstays were the most difficult part of the process for Andi and Peter, not because they were that technically complex but because finding somewhere to source them in a pandemic took a lot of time and effort, especially as neither of them knew who to even ask about finding aluminum bicycle tubing at the start of the project.

Andi explains, "We had 4 months of waiting after the design was already finished around May 2020. We had a supplier for the chainstays that well, did not have the chainstay tubes in the end and everything else was machined or ordered at that point. We tried to get matching tubes from all the European manufacturers that we knew where making Alu 7000 frames in Europe, but no luck. So, we had to order tubes from Taiwan, which obviously took some time (thank you Nancy, you are the best!). So, everything went to the welder in October and we got the frame end of November, perfectly timed for the summer riding season!"

The brake mount works with both wheel sizes and just needs a small adapter to deal with the change in length.

The Future for Shredmaster

This is version one of the frame that initially only intended to be a three frame run - one for Andi, one for Peter and a spare that they would have given away to a friend. However, after the bike blew up on Instagram, they have decided to refine their design before running a small production batch next year. The next frame will use a 225 Trunnion shock so the standover can be lowered plus some further refinements. Andi says, "We don’t want to rush it. This will require more bike park testing and fatigue-lab tests before anything is offered. Don’t wanna see our chainstays bend in the huck-to-flat test! Rough costs? Not at this stage, I’m afraid."

The bike has only had one test ride at this point but will undergo plenty more before Andi and Peter are ready to make the bike public.

When asked about the potential for some other designs, Andi replied, "Other bikes? Let’s see where this is going and then I guess, we just have to figure out a sick business model!" Watch this space.

 @cougar797: Enduro bike please. It's crazy to me we're in this "weight doesn't matter" thinking and aren't charging forward with gearboxes. I've ripped 3 12 speed derailleurs off in the past year. I'd imagine jumps with the gearbox would be similar to my eeb. Amazing "arc feeling" and never being pitched forward, no matter how fast the rebound is, because of the extra weight at your feet.
My prediction is that enduro and freeride bikes will go back to short cage derailleurs and a 46t cog somewhere in the future, but it should be a gearbox.
  • 7 0
 @coletrane-mtb: After getting to play with a gear box bike I just see no reason as to why its not moving forward. Derailleurs work fairly well ya, but... Its a fight to keep my shifting crisp. Cassettes and derailleurs are expensive and if you compare that cost to a gearbox it makes that extra little bit not seem so steep. Trying to keep my back end quiet with a non static chain drives me crazy. Wear wise, gearbox system wear as opposed to cassette, derailleur wear is just way easier to maintain. Finally the bike industry is all about these little performance improvements but none of them want to talk about rear triangle unsprung weight effect on suspension or the stability added by moving that weight low and central under your feet. It makes no sense.

 It is measured in mm. They use the comma as decimal separator. Cannondale is actually one of the rare ones who uses cm instead of mm for geometry numbers. Using m (meter) is uncommon as far as I've seen.

 It's not in meters, it's in mm. The point and the comma serve opposite purposes in many places outside of North America. We've also had wheelbases longer than a meter for quite a while. The OG Ibis Mojo, designed circa 2006, is approx 1.1 meters for size large, for example.

 @fartymarty: People need to chill. I personally prefer to measure tire pressure in bar, it seems quite common here in PB to give it in psi. If people refuse to accept weights in pounds and stone (1 stone = 14 pounds) and refuse to accept dimensions in inches, feet and yard (conversion given above) yet adhere to psi (pounds per square inch) then they do indeed adhere to a mixed system. I'm fine with a mixed system and typically give my length in feet here on PB as I'm indeed 183cm tall.

  • 2 0
 @JSTootell: To be honest I actually like fractions if they can be more accurate and/or compact than decimal numbers. That said from what I've seen the fractions used there typically have a power of two in the denominator so you can reach the same accuracy with decimal numbers. Plus of course in this particular case of dimensions, these aren't 100% accurate by nature so the accuracy these fractions suggest is false. Even though I've been taught in my studies (aerospace engineering where SI and imperial are equally common) to be able to work with both systems, I now realize I never knew how they show the significant numbers when showing dimensions with fractions. As you're American, may I ask you how you've been taught to deal with that, significant numbers? Or is it that once that's relevant, you go back to decimal?
  • 1 0
 @vinay: Really depends on what I am dealing with. I am not in engineering, I do maintenance work. In a lot of the stuff I do, accuracy to 1/16 is plenty (HVACR work), and often could be considered high resolution. When I was doing work on engines then we used decimal places to the accuracy of the measuring tools in metric units (typically, but sometimes in SI). So a measuring tool that could report to .00001 we would record .00001.

That is one of the annoying things about being in the maintenance field; never knowing if you are working on something that is SI or metric. My 1995 and 2012 Ford's are nearly all metric, but HVACR is all SI.

 The process of designing your own bike is quite enjoyable for me. As for the cost of the thing, as long as you use off the shelf tubing and keep your cnced parts to a minimum it can come out not too expensive. Think the grim donut.

 @Mattysville: Yes, but raw material isn't really capturing the full cost in this case, even if you put a $0 dollar value on the time to design. Some aluminum billet and a cnc'd linkage have very different costs, and a welder of that skill level isn't going to be cheap either.

 For anyone with Linkage X3, I've uploaded a model based on the the CAD drawing posted on their instagram. It's not exact, but pretty dang close. Honestly, the bike looks great! 110-120% anti-squat in the sag range, 100-70% ant-rise through the travel, and a consistant Leverage curve of ~32% progressivity, and 0 effective chain growth! The dude is running a really slack seat-tube angle (72deg), but I guess that's wanted for a bike largely pointed downhill. I can't really think of a better setup for a downhill bike, but then again I strictly ride mid-travel bikes. Nice Job Guys!!!!

 @cosmicCnidarian: thanks, first time I've heard of the distinction of 'lower' chain growth. Anyway I've often thought the term 'chain growth' as being disingenuous as we are actually talking about the chain stays lengthening, which with the horst link quite low and forward on this frame will create chainstay lengthening - maybe it's in total proportion to the chain lifting away from the chainring as it move thru the travel and hence as you say there is no chain growth?

 Seems like should have a motor as well?
Do not even need many gears as a DH e-bike?
One for going UP & maybe 3 for going down, Please make it happen?

 Nothing still ever will compare to Lahar - Way too exotic and clever for anything else to still come close.
Imagine if things had gone better business wise and things still going ok, what the bikes would be like now?

 Not being able to shift while pedaling a downhill bike seems like it would be annoying. Maybe gearboxes have changed since I have ridden one. You better send it to me so I can try it out and get back to you.

 You can shift into a heavier gear with pedal load.
To shift into an easier gear you need to unload.
A week's worth of adjustment overcomes this "issue" and work around the quirks.

 but you can shift into a gear whilst coasting, which would surely outweigh that annoyance. Like, rolling towards a jump you're worried you're going to slow into, you could shift into a harder gear whilst coasting and be straight on the pedals in the right gear

 @mattg95: I'm not sure if it's the kind you can shift while coasting. He said the gearbox adds the same amount of drag as a chain guide. The chain guide causes no drag unless you re pedaling. If the gearbox added drag whether pedaling or not that might be an issue for some. Unless I'm missing something here.

 @nyloracoftheshore: The bike has a normal rear hub. The drivetrain doesn't have any moving parts while coasting, aka no drag.
