aye man - seat tube length must be around 2-3 inches inside of the seat tube otherwise you're creating stress whenever you come down on the seat when its not set right - so if it is set too high then when you come down off a jump the seat you land on will stress the inside of the frame because there is enough room for it to essentially move around - but if it is 2-3 inches in the seat tube then you're lifetime warranty stays in effect and there should be no room for the tube to move round when you come down off jumps to cause such a stress fracture on the frame - sorry i was hard on yea just tryin to give yea a heads up as well - tho who knows what else could have caused your frame to snap - that is just one thing i could think of - well hope your remedy works out for u - im a remedy man myself and have done a few races with it - you'll need to upgrade the rear derailleur and then you're pretty much set - i had to cut my seat post on my remedy to get the seat all the way into the tubing - ill show you a shot of what it looks like - have a good one bud
