Hello everyone. I am new to the forum not new to biking. I've been around bikes since the late 80's building or fixing my own bikes. I was on a GT sponsored racing and stunt team back in the 90's. I have now been getting into mountain biking (although i don't live near any mountains). I am looking to upgrade my seat to something more comfortable as well as replacing my rear shock to something that can be adjusted and if need be locked out. the shock that is on my bike now loosens over time as i ride so its a real pain to have to readjust it every few weeks. Any suggestions on the seat and rear shock would be of great help.
