Fastest Woman in the World - Interbike 2017

Dinese Mueller record bike KHS


Denise Mueller-Korenek owns the women's speed record for cycling, at 147 miles an hour (237.74 kph) and now, the San Diego, California, resident is training to beat the world record: 268.831 kilometers an hour (167.044 mph), set by Dutch cyclist Fred Rompelberg. Both records were posted at the Bonneville salt flats, drafting only inches behind specially modified vehicles. Denise drafted a modified SUV, while Fred tucked in behind a similarly equipped dragster. The blistering speeds the two attained were made possible by eliminating most of the wind resistance, so the riders only needed to overcome the rolling and mechanical friction of the bicycle and the wind drag created by the spinning wheels. No small feat, it turns out.

The wheels are based around 17-inch motorcycle rims. The frame is carbon fiber and the gearing is so tall that Denise is towed up to 90 miles an hour before she can begin to pedal the bike.

The frame is carbon fiber, but it isn't lightweight. At the speeds she is travelling, there is no tolerance for frame flex. KHS is her sponsor, which gives them bragging rights that are enviable, to say the least. There is no fairing. The rider is tucked inside a "box" constructed behind a modified SUV and must remain within a foot or so behind a safety bumper in order to escape the wind. Even if she did have a clear view of what was ahead, Denise doesn't have the luxury, as her life, and the record she is seeking is dependent upon maintaining that tiny gap between the steel tube that protrudes from her bike and the safety bumper inside the box. She says the speed run is only four miles, and she is already over 100 miles an hour after mile one. Oh yeah - and she is wearing a ten-pound leather suit.

After she is towed up to 90 miles an hour, Denise pulls a lever on the handlebar to release the latch on the safety bumper to release the cable. From then on, it's up to her lungs and legs.

A two stage drive is needed to attain the record. "It doesn't look pretty," says Denise. "But. it gets the job done." One revolution of the pedals equals 150 feet of forward motion.

Wheels must be balanced and the tires feel as it they are solid rubber. Salt corrosion is apparent everywhere on her bike.

Four spokes had pulled out of the hub. No telling how that went down. There is no freewheel. Denise is also the fastest fixie rider in the world.

 Kudos to her, I mean that's no small feat. But being towed behind a dragster at 90 mph, drafting inside a modified box on a salt flat and then you start peddling? The whole point of a cycling record to me is that it is a human-powered accomplishment. Downvote me all you want but shouldn't this record be done starting from 0 mph? That's the difference between the fastest person sitting on a bike and the fastest person peddling a bike.

 Why not just drag her all the way to 168 and then she can let go and for that half second she has the record because she was was moving that fast. Thats not a biking record.

 "One revolution of the pedals equals 150 feet of forward motion"

Good luck starting a bike with that sort of gearing from zero!

 @Metacomet: yeah, this is the motor-paced category. worlds fastest unpaced (fully self propelled, not drafting) is ~89mph in a fully enclosed recumbent.

 Gearing would make it impossible to pedal from a stand-still. Even cars that go hundreds of miles per hour take miles to get up to speed. How long/far do you think it'd take a cyclist? That's the nature of super @#$%ing high land speed records, not because of perceived lack of will or cheating. Not just enjoy the feat and stop nitpicking at the layers, as Rick would say.

 @xy9ine: As a side note... at least mountain bikes have been evolving to the best geometry for riding off road. You can't say the same about road bikes which are so inefficient because they are subject to silly UCI restrictions. Recumbents make sense even if they are a little left field.

 @Ron-C: Exactly. On a properly geared bike on a road without drafting the top speed would likely be somewhere at 70mph. But at least it would be accurate. This "record" is vastly inflated nonsense data that has zero relevance to the sport.

 Aaron Gwin or Logic Bruni are the fastest guys on a pushy, thought that was obvious
  • 2 1
 @fartymarty: UCI only applies to UCI sanctioned racing. That's why people have actually invented recumbents. Because they're efficient even though you can't compete at an UCI race. Same goes for dissimilar wheel sizes. More DH athletes would probably have kept racing 29" front wheels if they were allowed to run a smaller wheel in the rear.

So yeah, mountainbikes have become amazing but that's still despite UCI regulations in competition.
  • 5 2
 I know! Why did they let Aaron Gwin win that contest when his chiain broke and he didn't pedal. Such nonsense. (Sarcasm for all you knuckleheads)

 In all fairness she's not going for an acceleration record. This is no different from the cars or motorcycles that run at Bonneville for top speed records and get a towed start because otherwise, with the gearing they run, they would need much more area to get up to speed and there's only so much usable runway there.

 @vinay: and probably all road bikes are made to fit the UCI rules.

I completely get recumbents but wouldn't want to ride ine in traffic as you are quite low.

There was some talk of the wheel size law being relaxed for MTB as it was only introduced as a safety measure when drafting as a smaller front wheel lets riders get closer to the bike in front. Hopefully this happens next year because 29F 275R is probably very good.

 @Ron-C: most exotic cars hit a quarter mile between 10-11 seconds at speeds higher than 120miles per hour. The Bugatto Chiron can hit 270 miles per hour in 32 seconds within 1.3 miles... Does not take much space to get up to speed. This car does 0 to 190 miles per hour in 13 seconds.... Its 0-100 in 6.5 seconds... 0-60 miles per hour in 2.4 seconds...

 @fartymarty: Not sure about the road bikes. One thing is what discipline you relate it to. Anyone can mount a triathlon handlebar to a road bike but you can't (and understandably shouldn't) use that in a race (or even traffic) with many other riders near. And I don't actually know whether pedal assist is mounted to (non commuter) road bicycles the same way we see it happen in mountainbiking. But to be honest I haven't looked enough into the scene to understand what is UCI approved and what people are riding.

As for the dissimilar front-rear wheels, it is a funny one. I recall an interview with an UCI official. I think it was Dirt magazine with Chris Ball but I'm not sure. He said they are open to dropping the rule but they principally don't change rules for next season as obviously brands are already developing stuff for that season. So earliest would be 2019. Which is silly in a way because it probably takes more for brands to modify their frames to accept 29" wheels in the rear than it is to tweak the geometry to work with dissimilar wheel diameters. Even sillier of course is that this only applies to rim diameter, not the outer tire diameter. I sometimes wonder whether these people at UCI sometimes also smash their heads against the wall about all the bureaucracy and the way they've defined their rules.

But yeah, that doesn't stop Liteville, Foes, Specialized, Banshee and the regular rider assembling their own bikes to actually ride the bike they believe is best. Some say racing is at the forefront but in reality, racing sometimes forces itself into a really conservative position.
  • 1 0
 @vinay: it was in Dirt mag - I remember reading it now. It would be relatively easy to mod a 275 bike to fit a larger front wheel but lots of time and money to make a 29 bike. Altho once you have a 29 bike you can always change back to a 275R as Chris Porter and Mojo guys have done... or just make longer CS to accept both.

It would be interesting for someone ti challenge the rule but I guess they would face disqualification. You wouldn't do it if you were to 10 but further down the field it maybe worth a go.

Yeah the UCI are just a bunch of road loving bureaucrats who see mtb as an innecessay evil. IMO the sooner we ditch them the better.

 The article raises more question than it answers, why no bigger wheels? Why v-brakes? Why the ridiculous amount of seatpost setback?
  • 4 0
 @bonkywonky: Let me try:

why no bigger wheels?
I expect they have trouble finding rims and tires certified for the speed she's going. And it was 17" rim diameter, was it? My experience was that a so called 20" bicycle rim actually takes a 16" moped tire (more or less) as the moped tire diameter refers to the rim diameter whereas the bicycle tire typically refers to the "expected" outer tire diameter. So yeah, what she's running may approach something like 22" in bicycle language.

Why v-brakes?
If she brakes, it'd be the end of her attempt. The main challenge will be to take all that heat. And a chunky rim like that is simply going to absorb more heat than the brake rotors we have in cycling. It may blow up a regular bicycle tube but it shouldn't harm a tire like this.

Why the ridiculous amount of seatpost setback?
In mountainbiking we've come to expect very steep seat tube angles because nowadays bicycle reviewers judge a bike by how steep you can climb whilst seated. So to compensate for that, seat tubes have gotten steeper. Same probably goes for road cycling. Climbing is critical. She's not going to climb with that bike so she simply chooses the seat tube angle that works best for seated tucking pedaling. And apparently for her that is what we see here. A seat angle not compromised for climbing (and not compromised for limited hip mobility many of us suffer from).

 If she got towed to 90mph then let go and immediately started slowing down yet got the record for hitting 89mph then yes, I would say its bogus. However at those speeds, even without wind resistance, the amount of friction on the tires alone would be huge let alone just being able to keep the bike out of death wobble. I'm impressed. I can't even draft a bus without getting winded after a while.

He said it was the most horrendously shit-your-pants scary thing he's ever done, and he's got more talent, experience and balls than any keyboard warrior on here.... and he got NOWHERE near Denise's record.
The next time you draft a bus, at 30mph, try getting within ONE foot of the back of it, right in the middle so it's the only thing you can see, and stay there for a mile. My money says not a single one of you wouldn't bottle it after a few hundred yards.

To think that someone with good health and decent skills could just pull this off without any training or preperation is silly to me.

Quite a daring speed on a bike and not something I would attempt. I've been over 150 mph on a superbike and that was realllly fast.

I still don't consider it a true land speed record though as she was not really pedaling and overcoming the typical obstacles that speed freaks have to deal with. Start from zero and see how fast your body can overcome those things. That's a thing.

 Technically she has to pedal from a stand still cause it's a fixed gear, I also believe the rules have something about it. Even though she is being towed. Crazier is guys would draft behind trains at around 80ish mph on runways of wood between the tracks back before they used salt flats.

 The video is interesting. When the car first started moving I was thinking, "That's not a fixie, the pedals aren't moving". But then I realized they were, just really really slowly.

Riding so close to the car at that speed is remarkable, moreso when you see that she periodically hits it with a bumpstop on her handlebars. Yikes.

But what really gives me the willies... After she hits the record, she backs off from the protective box on the car to slow down. I'd imagine there could be all kinds of little air vortexes that you run into at that speed, as you slowly leave the protective chamber of the car. I've hit 65MPH downhill on my road bike, and well remember cresting a small hill in the middle of a 5000 foot descent in Utah and being faced with an updraft that made handling very... interesting... for a few seconds. I imagine on a bad day she'd have that in spades.

I do think that calling this a "cycling" record is silly; perhaps a "drafting" record? But for that matter the real cycling record is set on a recumbent that looks nothing like a real bike. It's impressive nevertheless.
  • 5 1
 Its pretty impressive that the truck was able to do 140. In order for her to draft well the thing had to be made into a big wind screen, and getting that giant thing up to speed couldn't be easy.

 It is pretty insane to even try this, and I don't really see the point either but kudos to her for pulling it off. It sure doesn't seem easy to me.
Anyway, does anybody know the reasoning behind the small wheels? It seems weird if rolling resistance is your major enemy. Someone above mentioned centripetal force but that is wrong since that decreases with wheel size for a given ground speed (or it's equal if you account for a linear increase in mass). The only reason I could think of is less chance of being knocked to the side by small lateral air flows.
  • 1 0
 OK, I looked it up. It's to lower the center of gravity they say. Seems a little odd since the main contributor to COG is the rider, and therefore the crank length (which limits bb drop) will have the largest effect, but apparently this marginal gain is worth it.

 Wait. Is that brake using the 2nd chainring for a rotor?
  • 1 0
 I guess having the brake on the wheel could imbalance it. Not what you'd want at those speeds! :/

 apparently its a fixie, so putting it on the 1st chaining gives a lower Surface speed of the "disc" vs one on a wheel going 147 mph

 That's freaking crazy and amazing. It's scary enough to go 100mph+ on a motorcycle but to do it on a frankenbike like that? Just wow.

 maybe wash the bike so it won't corrode.. Just saying.

 last time i drifted was behind ambulance racing down 9th ave in NYC, the ambulance was going thru red lights and im behind him, on 14st a car hit me from the side, i was so lackey to get out of it with a little scratch, that car was totaled from just the impact of crashing into me. i felt the car so softly, it was so buzzer that i came out of it a live, i was checked in the hospital by so many doctors that couldn't believe that im a live, i'm guessing the speed and the adrenaline was the secret ingredient....but this crash got me off the bike for over 10 years, i had to wait all that time 'till mountain biking industry got to the level of today

 Yeah right. A car hit you on a bike, was totalled from the impact and you were fine. Smoke another one.

 @warmerdamj: yhha the cups and the firemans couldn't believe it all so when they checked the car....i'm smoking another one any way

 42 seconds- that's all it takes the new bugatti to go from 0-250mph-0. Now that's a record!

 Holy shit thats Nucking Futs!

 what is the difficulty level equal to with wind resistance. hmmm, about 40 mph maybe? not impressed with out wind resistance and all the forces that go along with it. come back with a real test record please.

 maybe she can do it on an e-bike in typical interbike fashion

 Not a fixie. The freewheeling happens on the jackshaft after the first chainring.
  • 1 0
 fairly certain you would die trying to ride a fixie that fast. if you had a brain lapse for a second ad stopped pedalling, those cranks would eject you (if it was fixed gear)
  • 1 0
 I don't see any evidence of a freewheel there, but would be interested to know if there is.

 RST? are they still not worth a dang?

 Good luck trying to slow down form 167mph with just a single v brake.
