    Which was the better fork. Girvin Vector or Amp Research ?

    I rode a bike with a Girvin Vector fork for a bit in the mid 90's. I think
    the elastomers could be upgraded to a coil or something. I'm trying to get my hands on a 1997 Stevenson Psychosis, a short travel high pivot suspension bike. A Girvin fork (with a coil spring ?) might be just the ticket, but I've always been curious about the AMP linkage forks. For those who've ridden both, which was the better fork ? Which was lighter ? How are they different ? Was one more reliable/durable than the other ?

    I've kind of had both. I had an Amp F-2 back in the mid 90s, and when it worked it was a decent fork (for the day). I've also had a Noleen Crosslink (the girvin's younger brother), and definitely liked that one. Out of the two i listed, I would definitely go with the Crosslink. Unfortunately, I can't say anything about the Vector. I believe it was less good.

    Amp Pros:
    Everything under the head tube

    Amp Cons:
    Pivots wear out super quickly
    Brake chatter (really bad!) when pivots start to go
    Suspension action wasn't super plush or amazing
    Fairly short travel

    Crosslink Pros:
    Plush travel
    Easily servicable
    Reasonable amount of travel

    Crosslink cons
    the "ULM" (upper link mount) had to be in a specific location limiting handlebar position
    Dual-crown style fork dented my frame on both sides
    A bit heavier than the AMP, but not a heavy fork
