I ride bicycles in the mountainous, bumpy terrain since 1998, I got my first real bike in 2001, it's the end of 2014 and a lot has changed for good since then, industry made more than a few leaps forward, oh yea. 2008-2012 was a boom in innovation and development that only a few could keep up with, even those with the fattest wallets struggled. But as Mike Levy points out
in his article things started to slow down recently and it's hard to see the next big thing. I agree with him that we may not see any technological breakthrough in close future, rather tiny adjustments. As a young grump, snob and aesthetics fetishist I don't like seeing that many bikes looking very similar - for me "Looks like a session" is not only an overused joke but also a symptom of a disease called "uniformity" caused by segmentation and optimization. I don't care about the suspension design details, geeky stuff - I care about what a regular bloke seeing a few bikes next to each other would think, would he understand why there are different brand names on Genius LT and Zesty? Enduro and Capra? What about bikes from same brand? Can you quickly spot the difference looking at a 5010 and a Bronson? Camber and Stumpjumper? But anyhow, I don't like whining without proposing a solid alternative and this is my take on break throughs, how cool could bikes look like in the future. In this article I present you:
2018 Cannon Rail JeronimoJeronimo embodies everything that an informed and trend conscious mountain biker might want. Not so long ago we had very capable "all-mountain" bikes, that maybe could not offer confidence inspiring stability at DH speeds, but they could ride everything relatively well, from XC track to DH track. These days, the Enduro World Series has set the bar very high, people race their 6" bikes on tracks that are gnarlier than most World Cup DH courses so to cope with the challenge, the new breed of Enduro bikes must be able to provide similar handling characteristics as a full on DH rig. Jeronimo has all the hottest numbers, that is a super slack head angle, adjustable between 61-63 degrees, the Uber long reach at 450mm for a Medium and efficient 76,5 degree seat angle. Everything is topped out by monstrous wheel base and conservative 436mm chain stays, harmless to a career of any World Cup Champion.
I guess the most outstanding feature of the whole bike is the single sided swing arm. Design has been successfully executed by the legendary
Alen Millyard but no big company has picked it up yet. Advancements in carbon fiber technology made it possible to create a system that is as stiff as symmetrical designs, yet lighter, shaving dramatic 150g of unsprung mass. However construction was not the only challenge, the design could work only with the use of Gearbox as there would be no way to mount a rear derailleur. The narrow wide rear cog is mounted like disc rotor on the outside of the hub. Chain tension is achieved via roller on clutch equipped rocker arm. On the front, Jeronimo sports the
Cannon Rail Hefty fork that I presented in one of previous
Waki-leaks installments. Unsprung mass and low stiction at it's best!
Suspension is controlled by a command unit at the top of the top tube, right behind the stem. Accelerometers in the crankset, fork and shock provide the system with all the necessary information how much compression and rebound damping will be needed to effectively ride across the obstacle. A rider can also manually adjust the level of compression and lock the suspension via one of many shifters mounted at the handlebars as well as touch LCD screen in command unit. There will be many presets available, tailored to particular tracks and riding styles. Cannon Rail uses similar features as
2017 Sheman-oh Corsair stem but Cannon Rail is so conscious of trends that it uses 35mm stem and the shortest stem from Sheman-Oh is 70mm which seems a bit old fashioned. Gearing is done by much anticipated Gearbox, controlled via hydraulic cables, just like the first ever, integrated dropper seat post, with internally controlled base height.
The last feature worth mentioning is the upcoming Envic G35 wheel set, using a mix of graphene and composites, which make the wheels not only lighter and stronger than carbon ones, but as compliant as aluminium. Thanks to that no spokes are needed, the wheel is super strong while allowing regular flex. Rims are as wide as 35mm on the outside providing perfect balance between stability, roll over and rolling resistance for tyres between 2.25 and 2.5".
As you can see, this bike has so many custom proprietary parts that commenters will have many essays to write about in 2020 when it comes out! Price will surely reach 15000 dollars. Thank you all for reading and for this year. I would like to thank Pinkbike for giving me the opportunity to show my art work and have my share of legitimate trolling. Big thanks to you guys - Pinkbike readers and commenters checking out my articles, I have received a great vibe from you in the comments and messages, they made it a pleasure to create all those wacky ideas.
I wish you all a peaceful and calm Christmas time. Please don't make any New Years resolutions... you'll buy tons of bike stuff anyways, enjoy it.
Arguably yours

Go to a engineer with a good amount of practical experience. Not a 'designer'. A real engineer/technologist/toolmaker/etc. Now explain to him the requirements of the suspension fork (suspension, flex, service life, etc) and have him/her quickly jot down some ideas.
How many came up with a single sided fork? Out of 10 here, nobody did, and in your respective tests, nobody will. Because it's a poor design for the application. The lefty was born out of a design department, and engineered thereafter. Anyone who's been following Cannondale's designs since the 80s, knows full well they design first, engineer after. Single shear pivots have been slowly removed from suspension designs and are rarely used in any modern design. Double shear, or bust. Period.
Hence Single sided swing arm on the Honda RC 30/45 and it was a design feature on the Ducati 916, double sided swing arms were stronger and lighter hence most other Superbikes using that design and Ducati trailing it and later adopting it on the 999 onwards.
If you want to believe it's better fine knock yourselves out.
Uniformity, functionalism, constructivism are horrible, they kill. Just like pimpage, overexcitement with aesthetics. There are many weird designs for a fork, but Cannondale made it work, not as well as others, but God damn close. The reason Jerome rise a Pike is because he is sponsored by SRAM. Anyone thinking pros chose what they ride basing on reason and engineering factor, not contract terms - raise your hand and think again. Josh Bryceland would ride 200mm Lefty if he got a deal better than SC Shimano.
@atrokz : engineers came with a single sided design for airplanes langing gear. And compare a lefty with your actual fork, do you still think the design has actual drawbacks?
@jamesroxby The lefty is stiff, light and don't suffer from bushing strictions. Look and prices are the only drawbacks of the design, IMO.
But I understand your point that people tend to be experts in their field and trying to work together is the difficult part. See link below...

Also, the Ducati street bike was a single swingarm (only for quick wheel changes), but they went back to double arms, because it's better. Anywhere lots of load is expected, you'll see a double swingarm (MX bikes for instance).
There are lighter, stiffer forks in the XC market. I wouldn't compare my 34 to a non comparable Lefty.

anyone remember when Cannondale tried to make a DH fork?
@atrokz, don't forget the stiffness gain of the bearings+square tubes, it takes a lot of loads so in fact, the conventionnal design with round tubes needs more material to be as stiff.
And, if you looks at strictions and guidance, the design of the lefty makes so much a difference compared to round tube, you don't need the other side anymore.
Hey, it's an interesting design/engineering exercise if nothing else.
Every social group needs a damn good freak to justify direction in which it is heading. Love thy enemy is not about sending flowers to Kalashnikov owner.
I suck at writing but Check out meaning of struggle in the dictionary.
@WAKI, some performative to you, if you please: could you draw a wheels a bit more rounder ?
What alloy mark do you plan to make the frames of ?
I guess you already have some ideas on how to make and weld 7075T6 or 7055T6 custom butted tubes
Or the tubes are supposed to be CNC routed out of the solid piece of alloy block for that $15000 price ?
I do not even admit the using of carbon. It's too banal.
Toe means a finger on the leg as I know.
So I mean the distance from the tip of crank to the tire when the cranks are parallel to the ground.
I really like the bikes with huge distance toe-tire, huge wheelbase and slack angle.
If it would help your marketing - common, use that slogan!
8-0 No sarcasm...Just a crazy imagination
But who knows, may be it's not so crazy already....
Especially on rude stupid comments out of the matter.
emerge, anger is the reaction of your subconsciousness trying to stop it from doing so, because if it would come out, you'd feel vulnerable, and supposedly lose the argument)
We may notice ininternet arguments, that if they are too long the opposing sides accuse themselves of their own treats (me and deeeight are a perfect example)
Cheers!
You will find me too, being enthusiatic to the point of absolutist when it comes to education and often look at myself and think I feel sorry for anyone who tries to talk to me about it. I do not suffer fools easily when talking about Ed.Psych or how we can help others learn. I am sure I am called all kinds of names under the sun. Happy Hols mate and enjoy the day.
A square tube has stress concentration points. ( stupid )
Shear forces on the one sided axle are atrocious. ( stupid )
Everything is proprietary. ( stupid )
Its a bike fork...not a F/A-18 landing gear needing to be as compact as can be... ( stupid )
Go figure out the rest by yourselves !!! its called marketing !!!
The Lefty is a over-engineered solution to a problem that never existed. Go find a single hydraulic cylinder/shock absorber with a square tube stanchion I DARE you.
Or am I missing something...
Oh, googling for some lefty I've found this:
tjewkwfmuc.blogcu.com/service-manual-for-cannondale-lefty-fork/13597697
And besides lefties, if to swap the handlebar and fork steerer - this is interesting idea how to increase you wheelbase(toe room, angle, change the headtube to bigger diameter)
The beauty of bicycles is that there is room for all this stuff, whether it initiates from dreamers, engineers or marketers...the market will dictate what ultimately resonates with us riders. It's a gamble either way for companies to buck the trends and try something fresh. Sometimes you have to throw around some far out and wacky ideas to get to a good one that hasn't come along yet.

The Jeronimo will, of course, be sporting the, by then, new industry standard 148mm JoostBoost hub standard surely?
Plus you're upping the q factor. heck, we only went to 135 to fit in more gears. when you start getting below 8 speed hubs, the rear spacing is actually narrower: sheldonbrown.com/frame-spacing.html They stopped getting bigger at that point because there's disadvantages, like q factor, extra weight, etc where it wasn't as big a deal below 135mm.
I would have at least liked to see something that would have had some backwards compatibility: why not make it 150mm, then you ought to be able to retrofit an existing 150OLD hub with endcaps or axle swaps? or just use the 157mm standard?
Oh, wait, adults can have one, too, on the Cannondale Hooligan. Yes, this bike is real, in production, and no, it does not fold. It's an adults' bike with 20" wheels without the folding excuse. gadgetreview.com/wp-content/uploads/2012/03/p4pb3962134-650x433.jpg

But of course it is just my point of view.
Realistically we'll never see this on bikes, there's no way it is ever advantageous weight wise.
Accounting for wheelbase, stock stem length, ST angle, HT angle, reach, and stack the Foxy Carbon XR medium is BIGGER than a Nomad V3 XL! How crazy is that?
Happy Holidays, @WAKIdesigns, and keep up the good work!
your layout only shortens the wheelbase without offering any significant travel

I know, last day before Christmas, i had to go to the office but did not feel like working at all...
Happy holidays! and no offense
I would like to see more work from you - hope you will consider this idea ;-)
Cause one side swing arms/ forks are nothing new and they are not as interesting as roller on a clutch. This may be a revolution.
Second thing... head angle... Maybe it is just the dwg, but it looks ridiculous. I have serious doubts about bikes with so small HA.
BTW, Pinion Gearbox has 18 speeds, and electronic control would be even better than hydraulic.
Single crown lefty??? No way. It's perfect as it is.
And what about big fat tires, that's going to be the next big thing.

In sticking vigorously with the lefty principle a design problem occurred.
As any good designer knows you can't backpedal on your original design, it make you look silly, like you hadn't though it through.
What's needed i more innovation. Enter entirely new drive system because a dérailleur won't fit.
I love it!
Keep in mind this is all so we can save the weight of an axle, a few bearings, & some reinforcement for a pivot. This falls under the same category as some the of sub 10lb road bikes people have been putting together lately: cool that they can pull it off, but I'm more than willing to gain a few lbs in order to have something that will last, & that I have confidence in due to engineering for a a balance between weight, strength & good suspension performance, vs focusing on weight savings.
Not to mention @WAKIdesigns isn't wrong about that front shock mount.
The universal take-away from most of the reviews I read, were that it made the suspensions so harsh that they weren't really worth the weight & price premium over a hardtail.
edit: to clarify: the flex member is essentially a leaf spring. when you've got an air spring in the damper as well, you've got 2 springs at each end of the system, at different spring rates, & you can't tune one.

what i want to know is can you fit a water bottle in the front triangle. and 450 reach on a medium? really...
Nice touch dude.
*do i hav to insert "j/k" or #sarcasm everytime, yawn
Beautiful design and drawings Waki!
