Thats great. I appreciate all of the information. I was very sure that the process went something like that. JIC is the same way but they will swap the springs on a set for you rather than just charging you for two sets. You can also go up or down more than 2kg with the addition of helper springs without the need to revalve. We just sold a 12/12 set of JICs for a customer that does road racing. There are a couple different options out there, the teins or the JICs are good options.
