The Bicycle Wheel: From Wood to Carbon

/ 01

The Spoked Wheel (1869)

The earliest bicycles — Drais's Laufmaschine and the Michaux velocipede — had compression-spoke wheels: wooden spokes like a wagon wheel, iron tyres shrunk onto the rim. They were brutal.

In 1869 Parisian mechanic Eugène Meyer patented the tension-spoke wheel: thin wire spokes pulled the rim toward the hub, putting each spoke in tension. The tension-spoke wheel was dramatically lighter and stronger than a compression-spoke wooden wheel of the same diameter, and it made the 60-inch front wheel of the 1870s Ordinary possible.

Pneumatic Tires and Tubulars

John Dunlop's 1888 pneumatic tire transformed wheels a second time. Wheels could now be lighter still, because the tire absorbed the road. Early racing wheels used tubular (or sew-up) tyres — the tyre was sewn shut around an inner tube and cimented directly to a rim with no bead.

Tubulars stayed glued to the rim in corners, ran safely flat, and dominated pro racing from the 1890s to the 1980s. The wheel existed to hold the tyre, not to brake against.

Rims: Steel, Wood, Alloy

Rims were originally wood, then steel. Steel was durable but heavy and prone to rust. Wooden rims — often laminated maple — were light and beautiful but disintegrated in the wet.

Aluminium alloy rims, pioneered by companies like Weinmann and Mavic from the 1930s onward, slowly took over after the Second World War. They were lighter, stiffer, and did not rust. By the 1970s, alloy box-section rims — Mavic MA40, Campagnolo Lambda — were the road standard.

The Aero Era (1980s–1990s)

Wind-tunnel data entered cycling in the late 1980s. Wheels, which rotate into a relative wind and present a wide, draggy cross-section, became an obvious target. Aero rims got deeper: 30mm, then 50mm, then 80mm, then full disc.

Tri-spoke and five-spoke composite wheels (Specialized Tri-Spoke, Campagnolo Shamal, Mavic Cosmic) followed. Pro time-trial setups used a deep-section front wheel and a disc rear; road race setups gravitated toward 40–50mm mid-depth rims as a compromise between aero and crosswind stability.

Carbon Fibre (1990s–)

Carbon fibre rims appeared in the 1990s. They were expensive, fragile on impact, and initially braked poorly. By the 2010s, carbon layup engineering, high-temperature resins, and improved brake tracks made carbon clinchers reliable enough for everyday use.

Today every WorldTour wheelset of consequence is carbon. Rim profile has evolved from V-shape to U-shape to wide, toroidal shapes that handle crosswinds and wider 25–28mm tyres cleanly.
