"Trigger shifters" is pretty close to being a standard generic term for them. Basically all English-speaking mechanics would recognize it as meaning the type of shifter and only the type of shifter yo …

All other factors equal, physically larger gears on bikes tend to be more efficient. Technically the extra weight of bigger gears counteracts this some amount. Larger gears also wear slower. …

If the b-tension (angle adjustment) screw is out too far it can cause the derailer to jam against the largest cog and get hung up a bit when shifting to smaller ones. Having too large of a largest cog …

Using an 8 or 9 tooth BMX cassette hub will get you into the normal useful range for singlespeed gearing pretty easily with a normal large road ring. 53-9 on a 12" gets you about 70 gear-inches for ex …

Everything here depends on what rear hub you have, specifically what type of freehub body it has (the part that the cassette mounts on). Given that it seems to be a frankenbike, it could be a lot of t …

They have totally different bolt patterns, 96mm asymmetrical for 8000 and 110mm asymmetrical for 5800.

Being able to easily compare gearing across bikes with different crank lengths is the main reason why Sheldon Brown advocated switching to the proposed Gain Ratios system for expressing bicycle gearin …

The gearing range and the interval between available gears tell an equally or more important part of the story. …

You need an 8-speed cassette with the same large cog size as your bike is set up for and an 1.85mm cassette spacer to adapt it to your 11 speed wheel. Together those are about $20US.

Divide the chainring tooth count by the cog tooth count. Multiply what you get by the circumference of the back tire. That's how far one rotation of the cranks is moving the bike. So why would that ta …

The most common cause by far is the cable tension needs to be adjusted. The other potential causes and contributing factors are cable/housing friction, housing damage, derailer hanger misalignment, de …

There are two different contexts this kind of question can come up in: When one is deciding between completely different routing schemes, i.e. a bike that gives you the ability to put the RD cable al …

In Shimano-ese, it is part of the "Outer Receiving Unit." You can pull up the exploded view diagram for you specific hub model on techdocs.shimano.com to corroborate what you need. Then you can go …

The only piece of it that can kinda sorta be re-used is the cranks. Front derailer cage gap to chain width compatibility is a real thing that matters and affects performance, and your 9-speed wheel wo …

For the most part, yes, all Shimano and Shimano-compatible (SRAM, Sunrace, etc) 8-speed cassettes are interchangeable in terms of their overall length and fit onto the freehub body. However, hubs from …
