Derived from a Scrub Alu (Identical bottom truck), this is Trampa's answer to the MBS Matrix, and the first all-metal adjustable channel truck to make it to market.
The kingpin assembly is different to MBS insofar as there is a nylon washer between the top and bottom truck which stops wear on the trucks from grit as mentioned in the MBS Matrix section.
It also eliminates the need for a bearing around the kingpin, which to be honest is a bit pointless on the Matrix as the bearing never does a full revolution.
Priced around the same as a regular matrix - probably the best truck available for the money IMHO.
A titanium kingpin upgrade is available for extra weight saving.
Warning: The thread (That secures the wheel to the truck) on a Trampa axle is slightly shorter than an MBS. Therefore, When fitting MBS hubs to a Trampa axle, you will need "Slimline Nuts" which are slightly thinner than standard wheel nuts.
