Love the storey, it’s so similar to my own I could just cut and paste it, except I grew up near New Quay West Wales, and my older brothers MBUK & MTBpro hand me down purchases were to blame. I too have since built the original dream JMC replica a few years ago. And so it’s made me list my spare original FSX brace on eBay for those like you who need them, in return for all those who helped me with mine...
Rockshox Judy FSX fork Brace, Original, V-brake style, NOT Cracked (Retro MTB). Condition is "Used". So this has been in the spares draw for a year or so now having swapped it out for the canti style version as needed for my retro build.
