hi there
not a real trial man but, I have practiced when I was youn
SUNN mountain bike's fan, a few months ago I found a bike from the brand dedicated to trial called " sunn xcircuit trial " with short size, short stays and reinforcement on the thread.
don't know if someone remember this machine, inspired by thierry girard's one, mtb trial world champion in the middle of 90's.
I try to rebuilt it, and I was trying to find a pair of 521 ceramic in 36 holes when I found a post on the forum, someone was searching for the same a few years ago.
don't know if I would be able to help you, but if you could help me I would be thankfull.
best regards
seb
