Did you find the Tech Tuesday information about coil and air springs useful?

 Not Kashima coating nor any other treatment will eliminate the starting friction of air-sprung shocks.
Air sprung shocks are not meant for heavy riders, the pressure needed is so high that it ruins their performance because of the starting friction and the exponential rate of compression.
No hammock effect on coil shocks.
Coils shocks are less expensive, unless artificially engineered for the contrary.
The chances of a coil shock failing...
And noneĀ“s going to tell me that turning a coil a little bit is more difficult than using an special pump to modify the air pressure. Not only is easier, is way more precise.
O yeah, they are heavier, I concede that.

 Hammok effect?

 Does it mean that if I don't roll over obstacles higher than a curb I don't need the negative spring on my fork at all, beacause I never have any chance to force the piston travel to its limit - i.e. to the point where the negative spring begins to take effect? Excuse me for my English.

 Oh, sorry, I found out where I was wrong - the travel meant is thru the spring expansion - not compression. So the suspension needs the neg. spring definitely.

 Where's the option for: No, the article was partially wrong and glossed over the most important comparison.

Contrary to the article, coil suspension is currently less expensive. Most riders use one or two springs, which still adds up to less than the cost of air suspension.

Durability is an important factor for many types of riders. How many years can each type go without service? Not to say this is the proper way to maintain suspension, but durability is a huuuge factor for most bikers.

 ^ fail, if the scenario is a CCDB v DBair - as the price is about the same and no need to buy coils to custom set the sag or have multiple rate options

 I think if you look at service intervals they are not too dissimilar between coil and air on shocks and very similar on forks. Bet you think 29ers suck too!

 air shocks need more regular maintenance. Its a built in fact. The seals that hold the air in on an air shock are under far more pressure than those that contain the oil inside a coil shock (or fork). Increased pressure means increased friction which means increased wear (and stiction, but thats another matter). Also if your oil seal starts to leak, it will need replacing soon. if an air seal starts to leak it needs replacing NOW!

 guys, this may sound stupid but.... which article ?

 I read the article, there was lots of mumble jumble, not mumbo jumbo.
