well it is a give and take. Due to the fact that these units are very precision machined they can cause some problems with taking the bar in and out for the first few times. Ive had some issues on a few bars but i simply had to use some elbow greese to get it in there. I weld in the clamps first then fit the tube to the other cagework. That way it is easy to weld in the clamps and it minimizes the distortion. Also, i keep it clamped together while welding the other tubes in place.
the benefits to these clamps are from the interlocking precision machined teeth. They will never rattle or get pulled apart. In seveal instances i have seen the 4130 tubing bend/shear before anything happend to the tube clamp. They were designed for the high end off-road race industry so the strength was the first concern when designing them.
For any cagework we do that uses a removable section, these are the only option.
