The last iteration was 50 mm, I believe.
The design of the previous truck was good imo. I’ve had several sets (10-12 years ago, but I believe that was all the same stage, 4), and did some of my best skating on them.
Like all things crail, there has been times it been really easy to be cynical about the quality or their (crail’s) approach.
I’d try some. The height was great, true mid. The metal was softer and ground down quickly, which I like, in the streets. Turn well when set up loose.
This is all re: the older stuff. I brought it up not to confuse the issue, but mainly because most folks had very negative experience with royals (‘kid’ truck that could break on flatground tricks underneath beginners).
I’ll try about anything with trucks tho.
