I am ordering a new echo team in the next few days I looked up around this.
I gathered that short is better for spins and street style manuvers
Long is more for natural trials
I have been riding street on my chase for about 2 years so I know that geo means alot about how the bike handles but with the echo team that 30 mm will amke that huge a difference. In the end I went with the long becuse it is my first real all out trials rig, and becuse of my overall height beeing 6foot
