We'll play devil's advocate here to argue why this increasing suspension travel phase is out of control. So here's a bulleted list of why the "Just because it feels good doesn't make it right" wisdom is actually true:

MORE TRAVEL (140mm - 160mm)

•  Isn't really always needed, it just feels more comfortable
• More sag, more negative travel - less easy to get the front wheel off the ground
• Reduces the need for rider skill
• In compensating for rider skill it let's you get a little lazier
• The bike does nearly all of the work
• This feeds into the "One bike does it ALL" scenario
• Trendy - trendy -  trendy - trendy - trendy
• Your mother would ask: "So if your friends hucked off a cliff, you would huck too?" applies
  
• Lemmings - lemmings - lemmings - lemmings
• Glory seekers, image oriented
  
• YES, it will make you faster on the descents - that we concede
  

 LESS TRAVEL (110mm - 130mm)

• Lets you still connect with & feel out the trail
• Snappy suspension
• Quick, responsive
• Grooms for developing greater rider skills
• This is enough for the majority of rider - let's be honest now
• Counter -trend oriented (don't let trends persuade you)
• You know what is actually best for you
  

 Notice that we're not arguing against axle-to-crown lengths (aka ride heights) because we don't feel that aspect has negative effects.  We like tall forks.

We try it all. That's worth something, right?
