> both Tracker and Grindking make a 3 inch truck.
I didn't know that, sounds great. Can you provide URLs? I'd like to feature them on my list. Are the hangers of those trucks three inches flat, or longer than three inches?
> this is about the widest you would want for roller skates
But some use wider hangers, for example Trackers (I think the Freestyle's hangers are 3 3/8), and others use Indies (I think they are called 101, and their hanger seems to be 3 7/8). They might be better for grinding.
So far I couln't find regularly available trucks with hangers shorter than 3 3/8.
What's the length of the hanger on your prototype?
