The Legend air suspension has been on my '04 SEEG (the SpyderPsychle) since day one for over 38 thousand miles now and has worked as expected. It has the advantage of letting you ride the bike at differing heights depending on how much ground clearance you need for hard cornering, crossing over speed bumps, or gives you great handling ability in gravel parking lots by slamming it in the weeds. Us little, vertically challenged riders need that from time to time. [smiley=drink.gif] Har! The Legend folks I talked w/ claim to almost never have a call for replacement of the compressor and the replacement cost is no much (compared to the initial cost of the system which is in the high teens). Legend was the 1st as I understand to build this type system for our bikes and I do not know how it compares to the others available, but I've had absolutely no complaints with the system on my scooter. If you have specific questions, just PM me. [smiley=xyxthumbs.gif] spyder
