- Keep it clean.
- Grease the threads. Run the grease around the threads. Don't be shy with it, grease is good.
- The bottom bracket bearings. Screw fit bottom bracket cups have different threads and fit into specific sides of the frame. Here you can see they are marked 'Drive side' and 'Non-Drive side', along with an arrow to tell you which direction it must be turned to tighten it.
- Grease the threads. Screw fit cups should also be lightly greased. It's good practice even though you've also greased the threads of the bottom bracket shell.

A crank arm is just a crank, which is specifically defined as a “bent or vertical handle”. It comes from the Old English word cranc as part of crancstaef, a “weaver’s instrument”. When you add arm to the mix, it’s akin to saying DVD Disc (DVDisc), or GPS System (GPSystem) or PIN Number (PINumber). What a nerd might call a tautology. “BUT!”, you say...
The history of bike design largely centers on bottom brackets and their corresponding crank modifications through the decades. The most significant changes have only come in the last few decades.
Fixing a crank arm all depends on how you damaged it and how much damage is involved. Pedal threads are not easy to damage, but careless installation that even partially damages the threads may render the crank unusable. Even if you could install a pedal, tightening to torque tolerance would likely be impossible. Re-tapping the threads may work as ...
Are shorter crank arms better than longer crank arms? Surely a question every serious cyclist has asked at some time The convention is that the longer your legs, the longer the crank; the shorter your legs, the shorter the crank. Chris Froome at 1.86m in height uses 175mm cranks whereas Nairo Quintana at 1.67m uses 172.5mm, although if you were a b...
The manufacturing process spans several stages. A specialist workshop, often run by no more than two skilled operators, one of whom is usually the owner, performs a specific process at each stage. All the big brands rely on hundreds of small operators like this across Taiwan: small workshops perform the processing cheaper than if a brand were to do...

The non-drive side crank arm is the crank arm on the opposite side of the bicycle chain. It is a simple arm that properly connects the bicycle’s pedals and its bottom bracket.
