The Kirk Precision Magnesium Bike | The Revolution That Never Happened

[@gcntech]

What do you think of this incredibly unique bike?

[@soaringvulture]

It's very beautiful but, as a materials scientist, I'm not happy with magnesium as a frame material. The stuff is very brittle (that's why very few people drive real magnesium-wheeled cars on the road; they crack if you hit a curb). Even carbon fiber has more elongation. So it's got an I-beam frame design for rigidity but now you've lost magnesium's strength-to weight advantage. And when it does crack (probably someplace good like the bottom bracket) it's difficult to weld without compromising the strength of the surrounding material. And I don't know what the ride quality would be. I'm guessing that it's made of AZ91, the normal die-casting alloy. This is going to have some damping but nothing like titanium. It's probably going to transmit vibration pretty strongly because of the low density.

[@ericsonnen5248]

Cool bike to have in a collection! Maybe not a daily rider :-)

[@ericpmoss]

Fill the tires with hydrogen, and in a sprint crash, the skidding frame will ignite, and the whole thing will go up like the Hindenburg as it crosses the finish line.

[@paulbennington4571]

After I graduated from University with a degree in Mechanical Engineering, I joined an Engineering design firm in Basildon, Essex in the UK. All over the wall of our office were prototypes of this frame. The Company was called Hawtal Whiting Limited and they did much of the stress analysis of the frame using a Cray Super Computer. I think they are fascinating and beautiful and they remind me of the start of my career in Engineering.

[@winstoncat6785]

By the stories of how dreadfully the frames performed, the stress modelling can't have been very accurate.

I've have done a Kirk Precision restoration on our KZbin Channel, Frank Kirk's Daughter got in touch with a lovely letter saying how she got in to trouble as a young girl once for sticking her fingers in the clay prototype which was on the kitchen table. I recently parted with my Kirk and am a little sad I did. The Bikes were heavy but incredibly stiff. These bikes to this day still turn heads. Thanks Jon for another well presented video. All the best Andy

[@brianschiff7371]

You know when someone parks a restored 1960's car next to a new 2019, everyone says how much cooler the older car is. Same thing with the Kirk Precision. I don't care if it's as heavy as a truck, a group set from the stone age and as aero as a brick. I want one.

I actually have one of these, the Limited First Edition, I had forgotten all about it! I worked for Norsk Hydro at the time, Hydro was the largest magnesium producer in Europe and they decided to buy Kirk who had come to them to get both Mg and the manufacturing process, which had been developed for our Mg car rims. I think I still remember where I stored it, will check when I get back home!

I raced on a Kirk for years. But the Vitus forks would snap so I installed a Colnago fork, took care of that problem! You did want to re-epoxy the bottom bracket threads. I used a aerospace epoxy. Loved mine, and it was full Campy Chorus then added prototype transparent "Gripshift". Quite a sight.

[@skooterbrah]

I had a friend that rode on one of these until the early '90s. He absolutely adored it, and I think that he rather liked the attention it garnered, as well.

[@chrisk8187]

In early 1981 I built my "dream bike". It was a "CUSTOM" Gary Klein (look him up) all aluminum with boron fabric reinforced stays and fork. It was the first production aluminum bike (had FAT frame tubes) on the market AND craftsmanship of PERFECTION (also expensive as I had no one to account to). It was super smooth to ride and was a good climber! Tracked like a train on rails and "no fear" cornering. I cherry-picked the components; Cinelli stem, 333T handle bar, Modolo side pull brakes (reversed rear facing forward between the rear seat stay and seatpost (brakes at the time even better craftmanship than top of the line Campagnolo)! Zeus track crank (milled and drilled) with black Campy track pedals, six speed cluster, Huret factory "cut" out shift lever, Campy seatpost and Record rear derailleur with drilled jockey cages, Unicanitor nylon track saddle, glued on"sew-up" tires, High-E hubs, and an aluminum seat mounted double bottle rack. I did A LOT of extended solo and group rides back then (many sagged with painted pavement arrows) and nine yearly seven day northern Wisconsin SAAGBRAW (Sentinel Active American Great Bike Ride Across Wisconsin). Three routes 325 riders each concluding (after 350-400+ miles) in a huge western suburb park for a wonderful picnic for the riders and families (well over a thousand). This was the Wisconsin version of the still annual RAGBRAI (Register's Annual Great Bike Ride Iowa). Look it up, they ONLY allow 8,500 riders max. Due to it's uniqueness, my bike always had 15 or so, standing around after each day's ride to "comment" about it. Memories...........(I'm 72 now). Thanks for "sticking around" if you did!

[@johnmanyberries1]

Nice video presentation ! I , too , have a Limited First Edition that I found in the storage room of Conte's Cycles in Virginia Beach whilst working there in 1993 ... it was originally spec'd with Suntour Superbe Pro in 1986/87. I built it up as a Dura-Ace bike for time-trials after my Gardin Aero frame cracked at the BB ... it performed well until I put a 130mm rear wheel in when the spec was 126mm. It cracked at the rear brake 'arch' , as many did. On the original batch , this piece was added after the casting ; or so I am told... best / aecond best looking frame I own ... my AlpineStars Team Ti-Mega mtb frame is right there too ... and cracked ;)

[@hmlm_hmlm]

Kirk Precision bikes pop up here and there in Norwegian thrift stores as they were produced here for the most part. I bought one a couple of months ago and working on restoring the paint. The frame is wobbly, feels like riding with a hard spring as a top and bottom tube. When you get used to it its actually quite fun and comfortable to ride as the springy frame dampens the pavement.

[@molybdnum]

Back in 1968 when I lived in NYC I went to a bike shop and the owner has some very exotic and expensive bike parts. It was impressive because some 40 plus years later I remember being impressed. I just wish I could remember what they were. Right now I am building a nostalgic bike complete with five speed cassette and wing nuts. I just want to remember

[@williamberge4968]

Was a disaster to sprint on, bottom bracket was not center of pivot when sprinting so it had some awkward sideways motion down there.

[@jamiecox2506]

3 kids at my school had them in '92/'93. My old man got one from the charity shop, too. Those ones broke as the frames were prone to cracking on top of the top-tube, just behing the head-tube. Some got warranty replacements and some didn't. They looked cool at the time but they weren't up to any serious use.

When I was a juvenile, back in the 1970s, the resident legend in our club was a scientist. His claim to fame was a silver medal in the sprint at the 1968 Mexico Olympics. Anyway, he rode a frame made of Reynolds 531 tuning, but to make it lighter, he carefully drilled holes in the bottom bracket and the front and rear forks. The holes in the forks were slotted. As he rode, and he really was a good rider, his frame would whistle. It was a beautiful piece of subtle back shed engineering, which never resulted in a cracked frame.

Couple interesting things to note- looks like the levers are from a later 7400 group- they have the SLR return spring. Also (as noted in some other comments)- the DA seat post is the aero version, there was a round, fluted version as well (i had one of those...) made at the same time. And please ask them to put a period seat on that post! Next project- find us a bike with the Dura Ace AX group on it and focus on those lovely brakes...

Jon - love the enthusiasm for the Kirk! In a similar era, can you find a bike with a ~1988 Shimano Sante groupset for us? Madison/Freewheel imported the Kestrel that had Sante on it. Nobody ever saw Sante in real life, it was painted white and it had lots of innovation to it that was never seen again. Another bike worthy of you trying to bring to our attention is the 1987 Raleigh Triathlon. Triathlon hadn't existed in the UK before and Raleigh brought out a bargain priced space age machine that still had Reynolds 531. It used the new 105 with indexing, cool quick release 105 brakes, utterly awesome Biopace rings and no substitute parts that weren't 105. Raleigh also put the finishing kit to a new level, a seat that worked well in the wet, not one but an incredible TWO bottle cages, SR seatpost, bars and stem, Weinmann eyeletted narrow rims, Shimano freehub rear hub and foldable Cheng Shin tyres. Before this bike no foldable tyres had been seen in the wild outside the pro scene in regular bike shops. Although this might not look special today, at the time Raleigh were what bike shops sold and, in this one model, the British cyclist was seduced with the new sport of triathlon, incredible feature-complete Shimano technology and a bargain price. Nothing else had aero brake levers, sealed bearings and extra trinkets like how the Raleigh Triathlon had them. Even the paint was special, Raleigh had built the most expensive paint shop in the industry and started to use it around 1987 creatively. The practical aspects were good too - mudguard eyelets, adjustable rear dropoutand even a full length frame fitting pump. The bike may not have made it onto Tomorrow's World but it introduced a lot of people in the trade to Shimano 105 and the real tomorrow's world of incredible Shimano innovation.

[@amfearliathmor8213]

I purchased a NOS Sante Sante rear hub and Uniglide Cassette the other week. I'm going to end up building a pair of wheels with some Sapim Laser spokes and Mavic Mach 2 CDs rims. (if I can find them). The Sante hub is a quality bit of kit with a finish better than current Dura Ace and maybe even smoother bearings.

By mid 80s 53/39 was typical in US.

How about a Moulton spaceframe with Zzipper fairing?
