Why do we need air-filled tires?

There are two good answers here already, I'll add the relevant physics. Any suspension has three key variables: Its spring constant, i.e. how quickly the force rises as the suspension is compressed. ...

Why do we need air-filled tires?

We don't, and alternatives exist What we need is some level of compliance in the tyre. Rolling resistance at this level is governed by the tyre's ability to roll over small surface deviations. Air (...

Why do we need air-filled tires?

A wheel is essentially round, a road is essentially flat. For reasonable contact with the road that does not damage either wheel or road, the tire needs to be deformed at the contact point to make a ...

Wear-based maintenance/overhaul of air spring suspension fork

For starters, I think it's unfair to make a comparison with chains. Your chain is a fairly cheap part that is designed to be replaced frequently. Unless your wallet is overflowing, suspension is ...

How often should air spring forks be reinflated (topped up)?

For one, it depends on how sensitive you are to changes in suspension performance. You can’t really measure for any drop (your shock pump will initially steal some of the air chamber’s air in order to ...

Wear-based maintenance/overhaul of air spring suspension fork

There are no wear indicators on these items. You'd have to pull the lowers/air can and inspect the seals, bushings, and other wear components yourself. Personally, I keep a little spreadsheet of my ...

Wear-based maintenance/overhaul of air spring suspension fork

The wear indicator for a fork is the coating on the stanchions has worn though, meaning a very expensive repair requiring new uppers. Unlike a chain, these parts are not considered consumables by most ...
