Also (as you mentioned) if you are required to slow down or stop suddenly, it's convenient to be able to drop down several gears while simultaneously braking, then be in an appropriately low gear to accelerate … Some modern shifters allow downshifts of 4 or 5 gears. Yours may provide 2 with a full stroke of the lever, so the solution may be to simply 'half stroke' the lever to get a single downshift. …

You cannot get a higher gear ratio by replacing the cassette. The 11 tooth sprocket is the smallest you can get on a compatible cassette. (Systems with 10 tooth sprockets exist but use a different fre …

The specific model of rear derailleur you have is an Acera RD-M360 SGS, produced about 2009-2011, for 7 or 8 speed drivetrains. Shimano very helpfully provides archive specifications on the product in …

If your bike has slotted dropouts and a rear wheel secured with axle nuts (which Poster's answer implies you have) you can do a single speed conversion without the need for a chain tensioner device. …

The overlap in gear ratios that are available with each chainring is mainly a consequence of the practicalities of building a derailleur gear system. I.e., how many sprockets and what sizes can be fit …

Traditionally 'speeds' meant the number of gear configurations available. This is the number of sprockets in the cassette (or on the freewheel for older bikes) multiplied by the number of chainrings - …

That is not an intentional feature and it should not be happening. Check to see if the chain is in fact moving onto a larger sprocket under braking. Find a area where you can ride safely in a straight …

I think the article you reference is in error. Obviously a longer crank arm gives more leverage, requiring less pedaling force to move the bike but requiring a faster pedaling cadence the pedal to mov …

This is a common misconception. The shorter teeth are not chipped or broken off. Modern chainrings and cassette sprockets have features to assist the derailleur with moving the chain. The shorter te …

One cause of this is chainring wear. The teeth become slightly hook shaped, which catches the chain rollers and pulls the links up around the chainring. This will be exacerbated by introduction of a …

Shift into the lowest (innermost) gear. This removes the cable tension as much as possible without undoing the pinch bolt and removing the cable Loosen the bolt that clamps the derailleur to the seat …

A larger largest sprocket also means the ratio gaps between gears get bigger - the intermediate sprockets all get proportionately larger too. …

Trying to run a cassette with a too-wide range means you'll have big jumps between gears, and requires a derailleur that than handle the largest sprocket size. …

If you are looking to re-purpose off the shelf components: Fat bike forks use dropout spacings of 135mm and 150mm, I believe. Road disc brake bikes and some mountain bikes use 135mm rear spacing, so y …

The min large sprocket size that Shimano specifies for the RD-RX810 is 30 teeth. A 28 might work ok but I’d personally stick with 30. As others have mentioned swapping wheels is not plug and play. The …
