The Hidden Empire of Bike Parts: Why 90% of Your Bike Comes From One 60-km Circle

Quick question: who actually made your bike? If your answer is the brand name on the frame — congratulations, you're about to unlock the world only industry insiders know.

Taichung: the Silicon Valley of cycling, inside a 60-km circle

Draw a 60-km circle around Taichung and you enclose the densest bicycle-industry cluster on Earth: hundreds of specialist factories supplying each other within an hour's drive, completing supply chains that would span three countries anywhere else — the industry calls it the "golden valley". In 2003, arch-rivals Giant and Merida even teamed up with a dozen core component makers to form the "A-Team" alliance, with one goal: stop competing on price and push "Made in Taiwan" upmarket. Many premium parts sold under Western brand names roll off lines inside this circle.

Shimano's origin: an ironworks in the city of samurai swords

Sakai, Osaka, was Japan's sword-forging capital six hundred years ago, and that bladesmith culture left behind extraordinary metalworking craft. In 1921 Shozaburo Shimano rented a small ironworks there and built his first product — a bicycle freewheel, not a derailleur. A century later, Shimano holds roughly 70% of the global mid-to-high-end drivetrain market. Bonus fact: its fishing-tackle division is also world-class, because a freewheel's ratchet and a fishing reel are, at heart, the same craft.

SRAM is literally three people's names

Scott (lawyer Scott King) + Ray (founder Stan Ray Day's middle name) + Sam (engineer Sam Patterson) = SRAM. They started in 1987 with a single product — Grip Shift twist shifters — then acquired RockShox, Avid, Truvativ and Zipp to become the only group that goes head-to-head with Shimano. Next time someone asks how to pronounce SRAM, you have a story to tell.

Campagnolo: frozen fingers invented the quick release

November 1927: Italian racer Tullio Campagnolo was racing over the Croce d'Aune pass. Changing gears back then meant stopping, unscrewing wing nuts and flipping the rear wheel. His fingers froze in the snow, the nuts wouldn't budge, and he watched his rivals ride away. His words became legend: "Something has to change at the back!" Three years later he invented the quick-release skewer we still use today. Even less known: Campagnolo's precision machining later produced parts for NASA satellites and wheels for Ferrari.

Almost every chain on Earth comes from one town

Whatever brand is printed on your chain, odds are it was made by KMC in Tainan — the world's largest chain manufacturer, supplying virtually every major label; chains in different boxes at different prices may come off the same lines. Saddles tell the same story: Taiwan's Velo turns out tens of millions a year for a large share of global brands. The industry's open secret: the brand is marketing language, the origin is engineering language — and they're frequently not the same thing.

Japanese Keirin: a religion of components

Japanese Keirin is a legal betting sport, and to guarantee absolute fairness every race component must carry NJS certification: steel frames, hand assembly, approved makers, fixed specs — nearly unchanged for decades. A single NJS-stamped steel crank can cost more than a modern carbon crankset. In that world consistency matters more than progress — which is exactly why NJS parts became holy grails for fixed-gear collectors worldwide.

So what exactly is a "brand premium"?

For parts off the same production line, the branded version can cost 20–40% more. That premium buys real things — R&D, marketing, warranty networks — but not every part needs them. The simple split: "commodity spec" parts (bearings, chains, cassettes) from first-tier OEM lines can be identical to the branded version; "system" parts (complete drivetrains) genuinely earn the brand's integration R&D. Knowing which is which — that's what makes you the expert in the room.
