Disc brake road bikes, new tire sizes, new brake caliper brake placement, new models, new categories, new components.
The cycling industry has a spastic obsession with newness
The belief is that, to keep cycling compelling for consumers there must be a continuous flow of new products, exciting products.
But not necessarily better products.
In an incident today in Stage 1 of the Abu Dhabi Tour top professional rider Owain Doull of Team Sky told reporters his left shoe was sliced clean through by a disc brake rotor in a crash. Doull sustained additional cuts he attributed to the sharp-edged disc brake rotor from the racing bicycle of sprinting sensation Marcel Kittel of the Quick-Stop Floors pro team. The two were involved in a crash near the race finish; a common occurrence in fast, bunch sprints.
Disc brakes on road bikes have been a new feature for three years. The jury is still out if they are better. This latest exhibit does not bode well for the future of disc brakes on road bikes, and it isn’t the first time.
Gregor Brown of Velo-News.com wrote this today following the Abu Dhabi incident:
“It was not the first time a rider has accused disc rotors of inflicting damage. At Paris-Roubaix in 2016, Movistar’s Fran Ventoso claimed that a large cut on his lower leg was caused by a disc rotor used by the Roompot team. That assertion has been disputed, but Ventoso stands behind the story.”
The sales pitch is often something like, “Everything is going to disc brakes!” and “Cars use disc brakes, discs work better in wet weather.” But there is a contrarian argument to be made that disc brakes are a feature without a benefit, or, at least, not a benefit commensurate to their attendant drawbacks.
In a balance sheet format, disc brakes look something like this:
Advantages:
Better wet weather stopping performance than caliper brakes. Greater tire clearance at fork and rear triangle facilitating wider tires on disc equipped bikes. More frequent use of structural thru-axle wheel design for better lateral stiffness. Removal of braking surface from wheel rim allows new rim shape designs.
Drawbacks:
Reliance on disc-brake specific wheels. Difficulty maintaining adjustment of brake calipers relative to wheel brake disc. Slower wheel changes compared to caliper brakes. Difficulty moving wheels from one bike to another due to tight tolerances. Heavier weight. More expensive. Fewer wheel options for disc brakes. New maintenance requirements, especially with hydraulic disk brakes.
So the question for consumers is, do the drawbacks outweigh the benefits? Another attendant question for consumers is, “Was there anything wrong with caliper brakes?”
In fairness, road calipers have had decades to evolve. Brake surfaces, rim profiles, brake calipers, brake levers, brake pad materials and brake cables for caliper brakes have been evolving ever since they were invented in the late 1920’s. That is a century of technological evolution in favor of calipers.
Conversely, disc brakes are new to road bikes compared to calipers, and the technology is not quite ready for prime time. If it were, the incidents with rider injuries, complexity surrounding wheel changes and maintenance wouldn’t exist.
During the past two decades when the bike industry introduced a few ideas that made it to market when they arguably were not mature we saw an increase in service and warranty related inquiries. These included, most notably, bottom brackets following the move to press-fit bottom bracket formats.
And the bike industry has a dismal record of owning its bad judgment unless compelled to do so via litigation, usually in the form of mandated recalls or personal injury lawsuits. Until those things happen the pedal is to the metal on selling new innovations with an often-subordinated regard for technical merit, let alone safety or integrity.
Solution: Do a Better Job of Selling What Already Works.
While the bike industry has done a great job of introducing “new” it has mired itself in an increasing number of sales narratives.
For every new innovation there needs to be a new sales case, new sales materials, new web assets, new sales and distribution channels and new marketing materials. It takes time and resources to develop those assets, and they cost money. It makes sales conversations longer on the floor of the bike shop on Saturday morning. It may not increase sales, but it makes it longer to complete sales. There is simply more to talk about.
An alternative solution exists in other industries where price maintenance, dealer cooperation and better marketing of existing products along with more judicious management of the supply chain has maintained product quality, profit margin and customer satisfaction.
Perhaps the best example of maintaining profit and demand for a static, non-evolving product is the diamond industry. Despite the rising supply of diamonds (there is actually a surplus) and the introduction of nearly indistinguishable synthetic diamonds, prices for diamonds have consistently risen. The diamond industry has created an emotional perception of worth although all other metrics suggest diamond prices should be falling.
The bicycle industry has not mastered any version of this perceived value equation. It is consistently undercutting price and negotiating a seasonal “surplus” of inventory that has conditioned consumers to buy previous model years at discounts. While some bike brands have reduced the emphasis on model years this has resulted in sometimes-stale offerings since the marketing narrative was not supported vigorously enough within the bike industry. They forget to sell. But they remember to invent new shiny things.
When the bike industry begins to focus on the job of selling rather than the novelty of making shiny new things then product quality will improve and profit margins will follow. And, most importantly, consumers will get a better, safer, more valid product instead of just the latest shiny thing.
