[QUOTE="Warbleed, post: 635200, member: 549898"] Your ignorance really begins to annoy me. You foolishly and ignorantly assume "usable travel" and xmax to be synonymous, but no one but your foolish self ever made that asinine assumption. Here are the facts, since you aren't educated enough to understand them. The XMAX of the 12w7 is around 32mm, and around 34mm for the 13w7. The Xsus (this is NOT Xmech, it is Xsus, which is the point where Cms drops to 25% of the at rest value). The XXX and Brahma have an Xsus of around 32mm. The Xsus of the 12w7 is about 45mm, and around 50mm for the 13w7. Look at a DUMAX or Klippel report if you are actually dumb enough to try and debate that FACT. As Kmart said, while the Brahma and XXX hit a literal brickwall at about 32mm (shortly after Xsus, the spider actually physically HITS the top plate/bottom of the basket), whereas the W7 won't hit Xmech until around 50mm+. So in summary, the xmax of the drivers is extremely close, but if you try and push a XXX and Brahma much beyond 30-32mm, you are going to DAMAGE THE DRIVER AND POSSIBLY RIP THE SPIDER CLEAN OFF. With the W7, it can quite safely and easily move all the way to 45-50mm depending on model, before Xsus actually hits. That's still USABLE excursion. When the spider hits the top plate, that's where usable excursion ends. Now given that we know 45mm is > than 32mm, we can safely conclude that the W7 has more usable travel. I'd swear I was teaching this to a ****ing 4th grader. Try understanding what you are talking about instead of attempting to disagree with people who are simply stating facts, which you seem to consistently and miserably fail at comprehending. So beyond Xmax, the W7 is going to have LOWER distortion than the Brahma or XXX, and unlike the Brahma and XXX, it can very safely be excurted to 45-50mm, depending on model, before the suspension locks down, and even further before the spider ever comes close to hitting the top plate. With regard to the cooling system, it's simply a FACT that having cooling above top plate and venting in the former are going to promote better circulation, and therfore better cooling. We needn't consult JL's tech paper to figure that one out. I hope that's clear enough for you, and I hope you finally have realized that you don't have any idea what you are talking about. [/QUOTE]
