If you’re new-ish to the sport, you might only know RC’s name from seeing it here on Pinkbike where he was a tech editor for many years, but that’s really just the tip of his contributions to mountain biking. Episode 67 is the first of a multi-part series of talking to RC about his love of flying, building his own planes and teaching himself how to fly (yes, you read that correctly), his father's secret work for NASA, and even a massive (and very secret) explosion of a Saturn V rocket engine. Yes, this is a cycling podcast, so we do eventually get around to mountain bikes and RC's own company, Mantis Bicycles.
It's a wild ride, so strap in for part one in the life and times of Richard Cunningham. Got some questions for RC? Post 'em below and I'll ask him in part two where we'll also cover his time at Mountain Bike Action, the Wrecking Crew, crazy bikes from the 90s, magazines versus the internet, him joining Pinkbike, and probably a whole bunch on non-bike stories.
THE PINKBIKE PODCAST // EPISODE 67 - THE LIFE AND TIMES OF RICHARD CUNNINGHAM June 17th, 2021
Who else do you know that's built a plane in their living room?
Featuring a rotating cast of the editorial team and other guests, the Pinkbike podcast is a weekly update on all the latest stories from around the world of mountain biking, as well as some frank discussion about tech, racing, and everything in between.
I am absolutely at the edge of my seat listening to RC talk. Fascinating man and a pleasure to listen to. Levy does such a nice job conducting this as well; best one yet.
Honestly, I had a question for RC about every 10 seconds of every story he had, but I had to muzzle myself and let the man talk or it would have been a 10 hour episode.
I used to read his articles in the 90's working night shift driving taxi's in Banff, learned a great deal about bikes and spent all my free time riding and fixing my used Fila fully rigid, much of what I learned I got from Richard.
I would read RC's articles religiously in MBA in the 90s when I was a teenager. Dude was a mtb celebrity to me. Fast forward 20 years and he PM's me on here because he liked a comment I made or something, can't quite remember. Anyway here I was having a conversation with someone I looked at as mtb royalty all those years ago, teenage me would have crapped himself haha
My experience with RC is similar. I grew up in the 90’s reading MBA and his editorials. When I got my first carbon bike( 2012-ish) and was having a lot trouble setting it up correctly, I emailed him and he responded with some great advice on how to get adjusted correctly.
Fast forward to the present, I can now set up my bikes and help out my friends when their bikes aren’t set up correctly.
I've got a question for the podcast (but not for RC directly)
why do we tend to match fork travel to rear travel? fork travel is at an angle, so you lose around 10% of vertical travel for with a modern head angle (a 150mm fork has ~135mm vertical travel, the rest is rearwards). We don't measure rear travel by wheel path, we measure vertical - so shouldn't we measure both ends the same way (and thus put forks that are 10% longer than rear, if we want a 'balanced' bike)? I'm aware some bikes are like this, but a lot are still 150/150, 130/130 and so on
should travel not be bias by weight? i know in an ideal world your weight distribution between the wheels would be 50:50, but in practice that is rarely the case. for the most part, your rear wheel takes more of a beating than your front so should your rear not have more travel than the front so that the wheel can have an easier time?
Ooof no, cars on flat tarmac certainly benefit from 50/50 but I think that would cause huge problems with steering flop on an mtb, not to mention the difficulty to wheelie, manual and generally attack obstacles.
More travel in front is more natural— plenty ride hardtails with a suspension fork- I wouldn’t want to try the reverse.
If that travel is rearward on the fork, then the terrain you're riding isn't steep enough. That's not meant to be a troll, I mean that mountain bikes literally tend to need their suspension the most when they are headed down a hill, and the steeper it is, the more critical that suspension requirement is. If you're heading down a gnarly DH, that 64 degree head angle probably translates into near vertical front wheel travel relative to the direction of gravity.
On most bikes, that same hill will result in FORWARD rear wheel motion relative to gravity. Whether or not this is relevant to the choice of high vs low pivots is a decision I'll leave to those that pick a pivot location and are a dick about it
@enki: The vertical/horizontal travel observation still stands. This is relative to the rear suspension not the axis of the earth. Also if all of your trails have the same pitch the entire way through this might make sense but your idea that your fork should be vertical at all times had no basis in design or engineering of bikes.
I think its because the fork has a 1:1 leverage ratio vs linkage (non 1:1) in the rear. It makes sense if you look at each suspension system in isolation.
The unbalanced travel makes a lot of sense once the bikes are on a downhill slope.
@hughlunnon similar travel makes it much easier to match spring frequencies. Mismatched spring frequencies can feel kinda weird.. Bouncy up front and wallowy at the back.
@enki: I don't think that's true. Very few tracks are 30% decent. The head angle does help rearward movements as you hit rocks going forwards, but i recon my fork is rarely over vert
I'm not a fan of the big over-forking that some brands or consumers seem to like. It depends on the type of bike and terrain, of course, but they can feel unbalanced to me. There are definitely benefits in some settings, though.
I have admired RC for more than a decade, every time they bring him into the podcast I am like… wow what an interesting life, but now that I’ve heard about his father’s life...in contrast… I kind of wanna think of him as a disappointment, hahahah
Jk, RC should stay in the podcast as a regular IMO
RC is one of the smartest, humble, most creative guys out there. We're just lucky that our sport was one direction in which he chose to point his talents.
Does anyone else find the bike on top of the car a little odd? I've stared at it for several minutes and can't figure out how the front tire works. It overlaps the downtube, but wouldn't that render steering it completely useless? Perhaps there is some wizardry at play...
I'm chuckling because I live in Norco. I know exactly where the old Rocketdyne plant is as there are some DH trails that drop into it, and I've ridden my horse around it.
I'll have to ask my grandma about the explosion, but that was probably before she moved into town from Pasadena.
I always look forward to hearing RC on the podcast!
It was great hearing his thoughts on how the ex-roadies were stifling mountain bike innovation. I’d love to hear his thoughts on how “enduro bros” are making mountain biking better and/or worse.
Saw the title and thought "It's impossible to state who is the most important man in MTB, impossible!" Then saw RC's name and went, "Yeah, that makes sense." Now as for most important woman, that's a harder question; Missy Giove? Alison Sydor?
Damn. By far the best podcast I've heard in a long time. PB giving Rogan a run for his Spofity money thanks to RC. Also, kinda rad that I live a couple miles from that hill RC grew up trying to fly down...
So good! Well interviewed @mikelevy The man is up there on the list of most interesting. One thing I love about RC is his apparent fearlessness of failure... or perhaps fear but ability to take chances on something going catastrophically wrong anyways. I think a lot of young people are missing that- in the era of clout, super cool instagram bangers, entrance interviews for pre-school etc.- doing things for the sake of doing them regardless of how they look or turn out seems to be a dying art and with it will go a lot of creativity and innovation. All hail RC the humble hero!
Great Podcast. I'd definitely listen to each part of the 10 part series if it comes out.
Questions for @RichardCunningham Do you have an idea of how much money you were making at your peak - just when you decided to change paths and go with MBA? And how much did you make at MBA?
Did you ever get any royalties or other compensation for Giant having copied the design of the bike you built for Tomac?
I seem to remember the Mantis Pro Floater getting a rave review in MBA. Did you design that bike before working at MBA? or did its design come from things you learned while working at MBA?
I'm currently on a santa cruz chamelon A with 120mm fork recon. I'm 125ish pounds and have 158 psi in the fork but still seem to clap the fork often. Is there a way to fix this besides putting in more pressure? I'm switching to a full suspension. Any suggestions preferably under 4000.
@mikelevy, @Sscottt: I get that question often. When vehicles designed for a very narrow range of performance approach the pinnacle of their evolution, physics dictates their most efficient shape. That's why commercial airliners all look like Boeing 767s and F1 cars look like deep-ocean fish. In a funny way, that's where we are with mountain bike design. "Funny," because bike brands are not courageous enough to abandon the double diamond profile that has defined the bicycle since the invention of the safety bike in the 1800s. So, the true definition of the present mountain bike is: "The near perfection of an off road bicycle within the confines of a double diamond frame." Or, "looks like a Session." Carbon fiber has given us the wings to abandon that premise. Additive manufacturing could also play a role. That's where I would begin.
Do you think we are at time where material used in mtb component are probably close to an optimum ( or at least used where it make sense)? And is the Carbon fiber everything era is ''gone''? New material to come? Heck, i've seen some company using magnesium alloy tubing!
Thanks for the Podcast! Always a pleasure to hear the crazy RC stories!
I love them but try explaining it to someone who doesn't get them - you ride around in the woods (usually after dark) down steep ass trails often falling off and often coming home covered in blood, then do it again later in the week... - it makes no sense but hell its fun (and this is coming from a middle aged family man).
Thanks Pinkbike for this awesome episode, I can't wait for the next ones! I love all the mtb podcasts that are coming out these days, we're getting to know the behind-the-scenes of the mtb community and business, something that I appreciate a lot.
Mr. Cunningham is a legend of the sport and such an amazing storyteller. Like many, I used to read his articles in Mountain Bike Action magazine and it got me hooked on mountain biking. I was dreaming of becoming an mtb reviewer and writer, which would still be a dream job 25 years later. Thanks for the inspiration!
I loved this so much! I have so much respect for RC, while I may not agree with everything he writes, I appreciate his point of view and his knowledge...such a rad human. I remember lusting over his bikes and was so surprised when he took over from Zap...it was a refreshing change for MBA.
Anyway...as for things from road bikes that we need to banish from mountain bikes, let's put presta on that list...I can't believe it's taken over! #prestasucks
Question to RC @richardcunningham Do you regret not having faith in yourself to make mantis compete with specialised and trek? Love listening to your life story and your story telling ability.
History of RC sub podcast would be amazing. What an unbelievably complex and interesting fellow. I want to know the answers to all the other questions @mikelevy would've asked
@RichardCunningham Mark Greyson is how I got into mountain into biking. Great guy. My dad owned an auto repair shop a few doors down from one of his work shops in San Luis Obispo. At two different times I ended up owning a full suspension bike he made, the Black Shadow, and an InFusion. I didn't know enough about mtb then to truly appreciate them and I wish i still had the bikes, but it was apparent they were made with real skill and creativity.
Levy! You rapscallion! You got me interested in rockets, patio umbrellas, ultralights, short wingspan biplanes, welding, and motor bikes! Ain't nobody got time for that! Seriously though, I was just about to buy a boat, now I have other things rattling around in my melon.
Would you please create a summary page of ALL the questions answered in the podcast? It'd be good to reference, as sometimes I miss a podcast. (hangs head in shame)
Question to RC: @RichardCunningham What is your favourite stock mtb that you bought and that you didn't design or was involved with in any of the design process?
The Sidehack races where always a great time for everyone.
