Installing a Standard Compression System (SCS) clamp can be tricky if no one has shown you how to do it right. Even after you get your SCS installed, it can be challenging to get it locked down just right. When dealing with an SCS, the first and most important precaution you should keep in mind is to not let anyone that you don't trust mess with it. Often times, someone might be trying to help when they think they know what they are doing and they might accidentally wreck your $80 clamp. I don't let anyone else work on my kid's scooters not because I don't trust them, but because if I screw it up, then I have to pay for it. If someone else breaks a part, I don't want to deal with that awkward interaction of who has to pay for it.
