in 1984 but think 1985 i was given a stem to test one summer for about a month
it was from what i remember a suntour
?? it was a graphite stem that they needed
ridden before it went on sale well it snapped clean as it had flaws in the graphite
and i mashed my right wrist badly as the stem bolt went into it and ruptured it.
did they ever get made is my queston i think they did but havent rearly ever seen one for sale.
