Hi all... I have been MTB on and off for about 2 years but want to take it more seriously now... I have established that I need a lighter bike and a medium frame & dont have the budget for soft tail - but where do I start?? My budget is around R12k...would like new, but just because I am nervous to buy 2nd hand as a novice in terms of whats what... Throwing it out there to the experts! Please help
