Yeah i know what you mean.
Ive been riding about 8 months, but Im not a rough rider at all. I know as I get better I will try more rough stuff, but i could always get a downtube protector.
(My mate just bought a rockman slate 2 for his 26" bike, costing £450, and he's been riding as long as me )
Im in the process of upgrading my bike to make it much lighter and stronger and a frame is a vital part which can make the bike stronger and lighter.
Thanks for the advice though
