So I need some advice, I can get a 6 inch travel bike at a really good price or a 8 inch at a goodish price. it will mainly used for places such as Diablo where there are lifts etc, but I am not sure if i would find the 6 inch out of its depth too soon but it is a horst 4 link so rides better than 6 or do i get an 8inch single pivot. any advice greatly received
