Considering the price these are a great deal. They are 6mm thick, and the pin is ridiculously hard to “snap” into the hex. However that makes them very tight and reliable so far! The locking screw is fairly strong, but I rounded one out tightening it (big guy, big hands). I would definitely recommend these to anyone looking for a “solution” to removing the disk brake bs. The red anodized material is nice, but it is light (almost an orange tint). Does not match the deep MST RMX red, but, they are inside the wheel, so, does that really matter to you? Hope this review helps folks out. Keep RC alive!
