at the beginning of my trials "career" i was riding my very first marino,it was built after an ns bikes "holy" mixed with an inspired fourplay mk1.(turned out the skye being the same geo later lol)
was riding street/park back then,so i had a disc brake.was a shimano xt 785,everything shimano,180 rotor rt66.
after a few weeks of just backwheelhopping and stuff the first adapter gave in,it snapped right in its center part where the material is the thinnest,leading to the caliper mounting eye facing to the front of the bike snapping also.
put everything new on the bike,caliper,disc,adapter.thought it was because the brake was fairly old,so i chose the same brake again.
after a few weeks,same sh*t.
long story short,magura since then and never looked back (but hey,you wanted details )
