Sliders were REALLY flexy, had no adjustment range, were loaded with plastic internals, and felt generally kind of blah.Manitou forks have not been always stellar in terms or reliability and everything...but there's not much to argue about the fact that the 2003 Sherman Slider was an excellent fork.
They screwed up with the SPV, SPV Evolve...as well as the Travis Intrinsic-whatever...but the 2003 TPC+ Sherman Slider was great. It's just too bad it was only a 6" travel fork...
The 2001 XVert Super was also a very good fork. I seem to recall some people had problems with it...but personally, this fork served me very well for several years (OK, it was not bone-stock as I replaced the seals by those used on the Black and replaced the lubricating grease by motor-oil in order to have semi-bath lubrification irate2: ).
XVerts broke if you looked at them wrong and once again they were very average.
