In trying to install these, I had to get 110mm kingpins to replace the stock 90mm (Merlin MR29 chassis). They are 8mm kingpins. My concern is with the added length and flex. Also, the only kingpins I found were fully threaded, so they are thinner than a solid shaft and more prone to bending or breaking (I wanted a kingpin with a beveled head to use my stock eccentric pills in the bottom hole). Lastly, I would have to stack a dozen or more washers to take up space between the spindle and the C/yoke. I think I’m going to abandon the Snipers because we don’t have enough time to test and risk failure. Anyone else had the same issues but ran with no problems?
If I could find 8mm kingpins of 110mm length with the beveled head and solid shaft I might try it, but the full length threading just sounds like a recipe for failure outta the gate.
So I just looked at the SA-1 setup again. It looks like it is meant to be usded with a cap head bolt not a counter sink bold head. They provide a washer that has a rounded side and flat side. This allows for different angles of the kingpin without binding the flat surface of the bolt head and nut.
