My current bike is a cheap bike that's alright around town but does struggle and even break if you throw hills, sand etc at it. I'm looking at one of these
http://www.decathlon.co.uk/EN/8-1-2011-172069577/ which seems well specced for the money and has some good reviews. I'm just wondering whether I'm going to end up breaking this one if I try and get better at jumps and drop offs (Can't see me going over 5ft for a while).
What I'm wondering is would I need 120mm front and rear or am I going to be alright on a hardtail.
