Change Bike Chain and Cassette

Gadgets: Bike Mechanic Henry van Ingelandt share their best tips.

Somewhat simplified, one can say that all bicycle chains are structured in the same way, whether the chain is single speed or 11-split cartridges.

The chain is measured in inches and nearly all chains are of a half-inch dimensions, which measure aims at the distance between the rivets.

However, the chain width vary a lot, and then also the width of the teeth of the cartridge and the blade. Being a racer chain will not fit on a fixie depends on the much thicker teeth of the blade and drive back-they simply can not fit inside the narrow chain.

Different manufacturers say always understood that their brand is the best. Regardless of price and quality, we can say that all the chains are very similar and that it is possible to mix the brand as long as you stick to the correct number of gears. If you have 11-split cartridge, therefore also have a 11 split chain.

A narrower chain that is supposed to more gears than sitting original equipment usually works well. For example, operates a 10 shared chain on a 9-split cassette. But it can not do the opposite, because the chain then rub against the adjacent tooth of the cartridge.

However, a narrower chain caught lying on top of the small blade when you switch down the front. That’s because the blades are farther apart on a crank adapted for 9-piece than it is for the 10-piece.

The width or thickness of the teeth of the blades and cartridges do not differ much between 7-, 8-, 9-, 10- and 11-split, and why it works as usual.

But everything in moderation. Mixing between 7-piece and 11-piece might not be optimal, because, after all, is little difference between all systems.

A chain stretches with time and wear affects the function. The strain is something you measure the easiest simplest of 21 pieces rivets with a ruler. A new chain measures exactly 10 inches (254 millimeters), while a worn chain gradually becomes longer.

Want even more accurate answer, you can check the chain’s condition using a special tool that measures both the strain and wear on the rollers.

Cassettes are available in almost infinite variations. There are a different number of gears, different gear, variety, price and quality, and of course from different manufacturers.

The three largest producers-Shimano, SRAM and Campagnolo-has similarities but also differences. Shimano and SRAM uses the same standards on the pitch between the gears in a cartridge, and also in the pass against baknavets frihjulsbody. Campagnolo contrast, another division of the cassette, and also another design in supple body trace where the cartridge snaps.

Other manufacturers do not usually find on their own standard, but mostly in terms of their cartridges compatible with Shimano Sram or Campagnolo.

If you replace a worn cassette on your bike, you should find a new cartridge that has as many gears as the old, and suggested the same ratio. Then fit everything just as before, without any need for adjustments or other changes.

Do you want a different gear ratio, you can often change quite freely, but a mountain bike cassette on a race can be directly inappropriate. For although MTB cassette has as many switches as your racer cartridge, the largest cog – with up to 40 teeth – to be more than your rear derailleur can handle. Rear derailleurs are the limitations in the size of cassettes they work with.

To change the ratio, it is important that you check the chain length and test if the chain operates in all gears.

Keep in mind that a lighter gear may require longer chain.

And do not use the new cartridges with old worn chains or vice versa. It causes unnecessary wear on the new component and can also perform poorly under load. To change the cassette and chain simultaneously.

Manufacturers have technical specifications for LED bike lights and how all the components work together and their limitations for different gear ratios and so on. Check up on this before you make major changes on your bike.
