    Is the bicycle transmission stagnant in the end, or is the transmission is the ultimate mountain bike transmission home?

    2019/9/29 8:33:57

    The most vulnerable part of your bike is exactly what bike manufacturers want to keep: the transmission. Why? What are the advantages of an external transmission over a midshaft transmission and an internal transmission? Is the built-in transmission a gaudy luxury, or is it something dealers have deliberately ignored?

    菠萝蜜app下载 For now, though, it will be some time before built-in transmissions become widespread, until major bike makers start to adopt internal transmissions. But the results are frustrating because the major bike manufacturers don't design more products around gearboxes. Isn't it easy for them? Build a proven gearbox model and make it a popular model, advertise him and race one of his famous drivers. Isn't that the traditional way all new innovations get out to the public? First, of course, they should be able to afford it. This is exactly a few ideal niche brand short board.

    内变VS外变

    Think about it. Putting a gear shift on a very vulnerable part of your bike (the tail hook) seems counterintuitive in itself. It rocked and moved back and forth, driving the chain. If it's not a habit, isn't it a little unrealistic? And that's what keeps you going, what drives the system, and it's exposed to risk.

    菠萝蜜app下载 Conspiracy theorists say (and I agree) that all manufacturers, from mobile phones to cars, are deliberately putting outdated technologies into their products. So, no matter what the product is, you'll only make a profit if you buy it again. The manufacturers are not entirely to blame. They also need to make money, if not a BMW or an iphone or a trek can be replaced or repaired in 20 or 30 years, they will soon go out of business.

    But still, there are a lot of people who are following us, and if you think about it, we've gone from consumer to consumer. Bicycle rings consume a lot of back swivel, not to mention chains, flywheels, regulating wheels, tail hooks. None of these things will last us very long.

    菠萝蜜app下载 But the problem always wants two sides to see, below let us put aside this viewpoint, come to see the advantage that external transmission is what.

    The ubiquitous external transmission

    菠萝蜜app下载 Objectively speaking, it is very effective. And it shows up on almost every bike. From professional road vehicles, to roadside fakes, to heavy downhill monsters.

    For years, shimano and sram had been making these very bad, but very good, transmission systems. In fact, the transmission often needs maintenance every three or four months, but for the flywheel will be much less. At least in terms of durability, I haven't had a flywheel break so far.

    In terms of weight, there is no doubt that the external transmission system is the lightest choice. A gearbox may never be as light as a transmission. The flywheel does not need to be as strong and heavy as the gears in the gearbox, and it does not need to be lubricated inside the enclosed gearbox to keep it running smoothly.

    菠萝蜜app下载 The cost of weight loss is often enormous. For weight, every gram counts. So, if there is an option, it can be more efficient, more durable, but heavier, then it's not worth it. The extra 500-1,000 grams may not seem like a lot, but if you ride for a long time, or at a crucial moment in the race, it will show a difference. This is also the conclusion manufacturers need: the winer suite.

    From a price point of view, for the average driver, the mid-range transmission will work well and meet their needs, although it will lose some weight advantage and sensitivity. High-end gear change systems are not necessary for casual weekend rides and amateur RACES. But gearboxes, only high-end. A mid-range gearbox I wouldn't consider using, at least not yet. Because if it breaks, you lose the whole system, not one.

    But for now, there are no more options on the market. And very few people buy gearboxes, or can afford the high price, the point is that there is no cheaper option. For example, Alutech Cycles. They provide two kinds of frames, a midshaft gearbox with Pinion and an external gearbox like the XX1. But the price of the midshaft gearbox has nearly doubled. This is a more difficult price to accept. Shimano also made some cheaper flower drum's, such as the Alfine, which is currently used in DH bikes. As we mentioned before, "I don't even understand these designs, so tell me how you came up with them!" Inside the Zerode The G2 is the same, but it is rarely used in cars other than commuter and station wagons.

    The technology surrounding transmission transmission systems has developed by leaps and bounds. Chains, flywheels, and backlashes were stronger; The chain doesn't fall off, and the thin rear hook is stronger and less likely to require replacement. But how long will it last, how far will it continue down this evolutionary path, or is the external transmission just the beginning of a conventional system?
