  • Why Chains are Still Better for Bicycles than Belts

    Theoretically a belt drive makes for a great upgrade to a bicycle, as it replaces the heavier, noisy and relatively maintenance-heavy roller chain with a zero-maintenance, whisper-quiet and extremely reliable belt that’s rated at an amazing 20-30,000 km before needing a replacement. Of course, that’s the glossy marketing brochure version of reality, which differed significantly from what [Tristan Ridley] experienced whilst cycling around the globe.

    Although initially he was rather happy with his bike, its sealed car-like Pinion gearbox and Gates carbon belt drive system, while out in the wilds of Utah he had a breakdown when the belt snapped. When the spare belt that he had carried with him for the past months also snapped minutes later after fitting it on, it made him decide to switch back to the traditional bush roller chain.

    Despite this type of chain drive tracing its roots all the way back to Leonardo da Vinci, they actually offer many advantages over the fancy carbon-fiber-reinforced polyurethane belt. Although with the Pinion gearbox the inability to use a derailleur gearing system is no big deal, [Tristan] found that the ‘zero maintenance’ part of the belt was not true for less hospitable roads

    A big issue was that of abrasive dust, which created a very noisy coating on the belt that’d have to be regularly cleaned off with precious water, or by having silicone lubricant sprayed on the belt. Even with all that care he found that the belt would snap after about 8,000 km, well below the rated endurance.

    When it came to super-sticky mud, called peanut butter mud for good reasons, he found that chains also cope much better with this, as the mud will just squeeze out of the chain and be forced off the sprocket, whereas the belt will happily keep compacting the mud onto the contact surfaces, increasing belt tension and requiring constant cleaning to not become hopelessly stuck.

    The Utah breakdown also showed why these belts are actually very fragile: the replacement belt had been packed away folded-up for a few months at that point in the luggage, and during storage the carbon fibers had become compromised to the point where the belt just snapped after a few minutes of use. A metal chain will happily be stored away for as long as you can keep it away from corrosion, and fold up very compactly.

    Another awesome feature of roller chains is that they’re super-modular, allowing you to carry spare links and such with you for in-the-field repairs, while even the most remote bicycle store in any country can help you out with maintenance and repairs, unlike the special and highly custom belts that need to be shipped in by courier.

    Of all the bicycle technologies that [Tristan] has used, it seems that only this drive belt has been an outright disappointment. The sealed gearbox would seem to be a massive improvement over finicky derailleurs, and hydraulic brakes are reliable and common enough that they haven’t been an issue so far.

    His conclusion is that bicycle drive belts are fine if you do city driving, where they probably will last the rated kilometers, but they rapidly fall apart in even slightly adverse conditions.

    I am up at the observatory in Victoria today (and for the whole week)! It is really fun to see a whole bunch of people I used to work with when I was a postdoc here, and be in a building that is completely full of astronomers!! Quite a change from Saskatchewan where I am the only professional research astronomer in the entire province... (Also it's sunny again and I want to go hike. But I will get some writing and emailing and talk-organizing done first...)#ProfSamLectureTour

    My talk on "Astronomy vs. the Billionaire Space Race" is for the RASC Victoria chapter's weekly astronomy cafe, and is open to the public (though you are encouraged to join the RASC. If you like astronomy stuff they are a great group!) More info about the location (the Fairfield Community Centre in Victoria at 7pm) and the meeting my talk will be part of is here: https://victoria.rasc.ca/astronomy-cafe/#ProfSamLectureTour

    Some more lovely walks near Comox today. Our farm-sitter called and asked about what to do with a power outage and -15C temperatures, and we talked him through the various steps to keep the well, the animal waterer, and the house from freezing. It was a wild disconnect to be super stressed out about very cold temps and damage back home, while standing on a beach on the very calm Salish Sea full of awesome birds.The power came back after 2 hours! No damage.#ProfSamLectureTour
