I have just recently put on a pair of 8.5" Krux K4's just to test them out for a while. I am about 4 sessions in and the first thing I noticed is the turning is horribly sluggish. I have them loosened up to the point the hanger wobbles. I am riding them with 54mm wheels and can't even get wheelbite unless I lean hard and even then it's a struggle. Also the responsiveness/depth of turning seems to be really shallow. I have never had any other brands feel so un-responsive. I'm just testing them out to make a video review of them but I'm having a hard time wanting to skate them anymore. I am also surprised to see how many people on here like them and say they turn well.
My question is, do they take a long time to break in? Will they get any better? They seem to have such a shallow carve that even if they weren't so stiff they still wouldn't perform well. I just miss my indys but I feel like I should ride them for at least a few more sessions before I throw in the towel on them. So far they aren't even good enough for a cruiser deck. I'm interested to hear others experiences.
Krux K4 have the least amount of turn. It is what it is. This makes them the hardest truck to switch to. You'll think it's gonna carve and so you'll tip over and go "what the fuck", but if you take the time to get used to them you may find the stability helps you skate better.
They get a bad rap for this. No one needs to turn that god damn much. I've been skating Aces on my main because I skate in my driveway and a small park so yes I like to carve around my car or the flat bar at slow speeds and shit, but I ride Krux on my cruiser because they are the most stable at high speeds, have a nice high ollie, allow bigger wheels, and I can lock them up. Took a minute to get used to it, but I am now and it's great. In the back of my mind I feel like I might go full Krux eventually but I'm enjoying my Aces.
Check out the new Kevin Braun OJ super juice video on youtube. 60 mm wheels, no risers. Tell me he's not turning fine.
To answer your question, they break in slowly but will maintain the same feel for the most part.
