In the two hours I'd been in the shop, Brian had raised the saddle of my Wilier racing bike by tiny increments, three or four times, and shifted it back a centimetre on its rails; he'd replaced the handlebar stem for one 20 mm longer; finally, he exchanged my handlebar for a new one â a classic shaped bar with small âD' loops, âso your hands can reach the brake levers more easily,' he said. In that time, my position on the bike had changed significantly. I could feel it. My back was straighter. My weight was more evenly distributed. The new position felt more aerodynamic, more aggressive and, perhaps surprisingly, more comfortable. The bike looked better too: the longer stem and the new handlebar somehow made the machine look better proportioned. It was like placing a painting in the right frame, I thought.
The methodology behind the fitting process was simple enough: âBum, hands, feet â three contact points with the bike,' Brian said. First he got my saddle height exactly right. Then he adjusted the saddle backwards, to get me in a position to obtain the maximum leverage from the pedals. Finally, he worked on my hands.
Standing back again, dropping his long metal ruler to the floor and scribbling some notes, Brian said: âYou were a bit stuck on the bike before, plonked there like a brick. That's looking good now. Take the bike away. Come back in a month and we'll go for
a ride together. I'll want to know how it feels. If you're going to have a handmade bike, you want it to be yours, don't you? It's got to be exactly the right fit, right for you, not for anyone else.'
This goes to the heart of why anyone would want a hand-built bike: it will fit perfectly, like a bespoke suit from Savile Row. There are several other significant advantages â with the benefit of expert advice, you get to choose the ideal frame tubing diameters, wall thickness and butting lengths, which will fine tune the feel of the bike; importantly, you get a frame designed for the type of cycling you propose to do, where you propose to do it and even your riding style; you get to select the best components you can afford and the colour the frame will be painted; also, you get to savour the process of acquiring the frame; lastly, when the bike is complete and you're out on the road, the machine will turn heads. But really, it's all about having a bike that fits
you
perfectly, a bike that will provide years of pain-free cycling. Most large bike manufacturers produce between five and eight different sizes in each model of bike. The human race doesn't come in five, or even eight sizes.
To make his point, Brian had wheeled his own racing bike into the room. The frame was built by Jason. It was a beautiful bike, of course, but something significant happened when Brian jumped on to it, catching his weight on the pedals and his shoulder against the wall. The bike changed. It fitted Brian so perfectly that it came alive. It responded to his every move, as he shifted his hands briskly around the handlebars and transferred his weight back and forth.
Perhaps more surprising was that Brian changed too. Jumping on to the bike took thirty years off him. When he thrust his hands into the âD' of the handlebars and sunk his torso across the top tube, his eyes flamed. He was ready to chase down a breakaway from the peloton in a race or launch a sprint for the finishing line.
Just sitting on the bike, just being on his immaculate, bespoke bicycle summoned such powerful emotional memories that three decades of toil and wear were erased from his demeanour in a trice. The bike was a source of youthfulness and it was thrilling to witness.
But that wasn't the point. The point was made when Brian stepped off the bike, swung it round and wheeled it across to me. It was breathtakingly light, well balanced and delightful to hold in my fingers. But when I hopped on to it as Brian had done, there was no transformation. It didn't look special under me. I didn't feel special on top of it. Although Brian and I are the same height and roughly the same weight, we are physically different in many other ways. Our arm, torso, shoulder, leg and thigh measurements are unlikely to be the same. It was Brian's bike: it made me want my own more than ever.
There is a simple grace about an unadorned bicycle frame. Looking at the row of bare, handmade frames hanging on the wall of Brian's shop, something struck me: though they were all made from different types of tubing, painted to individual specifications with different dimensions and angles, and would be built up into different types of bicycle and ridden in very different ways over varied terrain by diverse humans, they were all â in one fundamental way â alike. The frames were all the same shape: diamond.
The first diamond-shaped frame bicycle â the Rover Safety â was manufactured in 1885, in the unloved city of Coventry. It was called the âsafety' because the wheels were the same size and small, the rider's centre of gravity was over the centre of the bike, and he or she could touch the ground with both feet: in short, it was safe to ride. It was the first modern bicycle â something we'd recognize and be able to pedal today.
The âinventor', John Kemp Starley, later said in a speech to the Royal Society of Arts:
The main principles which guided me in making this machine were to place the rider at the proper distance from the ground . . . to place the seat in the right position in relation to the pedals . . . to place the handles in such a position in relation to the seat that the rider could exert the greatest force upon the pedals with the least amount of fatigue.
It was almost exactly what Brian had been saying to me all morning. Where a rider's hands, feet and backside are placed on a bicycle for maximum efficiency, control and comfort is a matter of basic ergonomics, which has been essentially unchanged over a century.
These principles led Starley to design the lightest, strongest, cheapest, most rigid, most compact and ergonomically most efficient shape the bicycle frame could be. By 1890, âevery maker worthy of the name' in Coventry, Birmingham and Nottingham was producing a safety model. The safety swept away every type of bicycle that preceded it: velocipedes, high-wheelers, dwarf ordinaries, the Facile, the Kangaroo, tricycles, tandem tricycles and quadricycles were obsolete within a few years. The ultimate form of the bicycle had arrived.
Other safety-style bicycles were designed and patented before the Rover, but making the bicycle user-friendly animated Starley: his design was the best. He was also a good businessman and recognized the potential in the machine early on. In 1889, he adopted limited liability. In 1896, he floated J. K. Starley & Co
as the Rover Cycle Company. The capital financed the construction of the largest cycle works in Coventry, then the global centre of bicycle manufacturing, and enabled him to survive the first big downturn in the industry at the end of the 1890s.
In 1904, Rover moved into car manufacturing, which was so profitable, so quickly, that the company dropped the bicycle arm of the business altogether. Starley himself had died suddenly in 1901, aged 46. Every cycle firm in Coventry closed their works on the day of his funeral, which was attended by 20,000 people.
Perhaps the mourners had the prescience to know the Rover Safety was a transport phenomenon, and that the basic shape of the bicycle would remain unchanged for the whole of the twentieth century. Contrast the Wright Flyer, the world's first powered aircraft built by Wilbur and Orville Wright (both bike mechanics, as it happens) in 1903, with, say, Concorde. Or take Karl Benz's four-stroke vehicle powered by a gasoline engine, also invented in 1885, and compare it to a contemporary Formula 1 racing car.
In both modes of transport, aeroplane and motor car, the vehicles have changed almost continuously. With the Rover Safety, however, the modern bicycle arrived virtually perfectly formed. Today in aeroplanes and automobiles and countless other mechanical devices there are numerous design variations and opportunities for improvement. With the bicycle, there is one
absolute shape. Sir Isaac Newton said we make advances by standing on the shoulders of giants. No one has been able to climb upon Starley's back.
I've had nineteen bikes. This number includes neither bikes that I've owned for less than a month, nor the bikes I've never bothered to lock up. Out of those nineteen bikes, eighteen were built according to the principles of the Safety. The only exception was my Raleigh Tomahawk. The âape-hanger', hi-rise handlebars, different-sized wheels, odd-shaped frame and spongy saddle with backrest may have been as cool as the Lone Ranger, but riding a Tomahawk was like pedalling through molasses, dragging a dead pig. Like its big cousin, the Chopper, the Tomahawk was designed in response to the dirt-track roadster bikes popular in the USA in the late 1960s. For the manufacturer, Raleigh, the Chopper opened up a new market in children's bikes, and it marked a shift in the company's philosophy; the bicycle became a consumer goods product, rather than a valid form of transportation. Though remembered fondly, the Chopper was a toy, not a bicycle. It's the worst example of the collapse in confidence in the real value of the bicycle that happened in the 1970s.
The principal structural function of the bicycle frame is to âmaintain integrity' under loads, to have the strength and rigidity to hold the wheels in place and support the rider, and to absorb the rider's efforts in pedalling, braking and steering, as the machine rolls forward. The triangulated, tubular diamond frame
remains the best structure to do this. An architect or engineer would describe it as a âtruss structure': the diamond frame is a variation on the super-strong âseven-membered' truss, a common element in structural and mechanical engineering. Trusses on the roofs of buildings apply the same principles.
There have been hundreds, perhaps thousands of attempts to better the diamond frame design in the century and a quarter since it âset the fashion to the world'. None could be said to have got close. There have been innumerable refinements in the materials used to make frames, and the constructional aspects of bicycle tubing â non-round shapes, varying wall thicknesses, and tapered diametersâhave become highly sophisticated. But the basic diamond shape, made up of two triangles, remains unchanged. Racing, mountain, touring, hybrid, track, utility, cruiser, fixed-wheel, dirt-jumper, porteur and BMX â almost all bicycles are constructed with a diamond frame. Today, the global fleet numbers well over a billion: nearly every one is made to Starley's paradigm. You can spend $15 on a rusting roadster at a yard sale, or $120,000 on a 24-carat gold-plated bicycle encrusted with Swarovski crystals, and you'll still get a diamond frame.
The constant shape of the bicycle over the last century goes some way to explaining why, today, we find riding one so elementary. It's also why there is a sense of classical moderation in the kind of pleasure cycling offers. As the late Sheldon Brown, the esteemed bike mechanic wrote: The diamond frame âis one of the most nearly perfect pieces of design known, due to . . . its purity of form'.
When I rang Brian, a month after my initial fitting in the shop, to arrange our ride, he immediately asked: âHow's that bike?' I had ridden it daily and it was very comfortable. He recalled all the adjustments he'd made, even though he must have worked on hundreds of bikes in the intervening weeks. Only after I'd
commented on each of them to his satisfaction did he ask how I was.
