10 degree plates:

-SuperX, Jogger, Probe, Probe NTS, Junior Pro, Century, Century NTS, Classic, Classic NTS, Competitor, XK double action,

*smoother turns used on most recreational skates

45 degree plates

-Cyclone, Cyclone NTS, Invader, XK

*all will come with single action trucks UNLESS you request our NEW DA 45 trucks (addition cost)   

*quicker more response turns and a much tighter turning radius

*Use in some recreational, derby, speed, jam, etc.

1. single vs double action:  in theory the double action gives you two cushions instead of one and thus more adjustability.  Its like adding extra shocks on your car so you would be able to fine tune your ride better and have a larger range of adjustment.  In the past all 45 degree plates only came with a single action trucks, thats why we developed the double action 45 (DA45) truck.  Now you have the sharper turning 45 degree angle with all the adjustments of an double action truck.

2. the degree/angle of the truck, 10 vs 45 .  Ten or 15 degree trucks have a smoother more controlled turning effect and always had the double action cushions for more adjustability.  Became very popular in 1970s with the mass appeal of recreational rollerskating.  45 degrees has a faster and sharper turning effect with a much tighter turning radius.  Keep in mind that roller derby skaters have traditionally used a 45 because of its incredible response.

3. short forward mount...going with the DA 45 it seems.   When you take our Invader  or XK 4 plates and you add a DA45 truck on them what you do is artificially increase the wheel base, so to insure that you have a proper wheel base for you shoe size you down size on the plate back to the appropriate wheel base, thus a smaller plate.  Now since you have a smaller plate you need to shove it forward off the heel to position the front axle underneath the ball of the foot.  Now that being said some skaters have a personal need/want for the shortest possible plate on their skates thinking that the smaller the wheel base the tighter the turning. This is kind of the speed skating theory of mounting.  Just remember that when we send you an Invader DA45 plate that seems short for the shoe you are mounting, that we are really sending you a shorter plate that has the correct wheel base for your shoe size.
