We take a look at the brakes that changed cycling

The French made some frightful faux pas in their days of making cycle components: the AVA ‘death’ stem was prone to suddenly snapping; the plastic Simplex derailleurs were awful; but the Mafac Racer brakes were simply magnifique.

Un doigt suffit! (one finger’s enough) was the slogan that accompanied Mafac’s legendary brakes when they were introduced in 1952.

The company — Manufacture Arvernoise de Freins et Accessoires pour Cycles — had made one-finger braking possible for the first time in cycling’s history, but that was far from the Racer’s sole quality.

Mafac Racer brakes were unusually perfect for many cycling disciplines and types of bicycle. In an extraordinarily long life that spanned four decades, with production ceasing in the early 1980s, the revolutionary centre-pull won the Tour de France multiple times.

Before 1968, when Campagnolo’s first Record caliper was launched, Mafac Racers were a common sight in the pro peloton and its compact, aerodynamic profile made it the caliper of choice for the mid-century equipment-fanatic British time triallist.

The Racer was not only extremely versatile but also highly adjustable. The length of the straddle cable could easily be changed for different rim widths and the pads could move up or down, in and out and side to side thanks to a complicated but effective system of bolts, washers and spacers.

Function was exemplary, but so was form. The Mafac Racers, made from polished aluminium, had a curvy, alluring shape that was pure Gallic. The engraved Mafac logo and “Racer” in double speech marks — as if that wasn’t its actual name, rather a raffish nickname — gave it a flamboyant look.

The red bushings that framed the script in the 1970s iteration enhanced the effect. The only criticism of the Racer brake was that it squealed blood-curdlingly, making the approach to a corner sound much more alarming than it actually was.

Mafac made levers to go with its calipers, which were every bit as stylish. The best known version had a distinctive minimal rubber half hood that clipped to the lever body and was available in tan and black plus 1960s pastel shades.

Compared with modern calipers, the Racer can still hold its own. Whereas virtually every pre-1987 component  has become yesterday’s technology, the engineering principles that dictated the layout and function of Mafac’s centre-pull brakes are as current as ever.

In fact, Californian precision component manufacturer Paul recently revived the Racer design and now sells its own, more angular-looking version, the Paul Racer.

    Just my opinion but they were crap brakes then and they’re crap now. New pads are an improvement – and the Paul version is waaaay better – but the originals sucked. Eddy Merckx famously quipped that if a rider on a Mafac-equipped bike attacked him on a climb he would let him go – knowing full well that he could catch him on the descent given the disparity in braking ability. I’ve known riders who have almost died using these silly things – “never again!” is the refrain often heard.
