I have built them mainly for myself and my family.
I first built a LCFS958 size L for myself and a LCFS911 size S for my wife. However the LCFS911 felt a bit small for her so I built a new one, size M for her and I gave the size S to my son.
My sun is growing so I upgraded my wife with a LCFS713 and we gave the LCFS911 size M to my son, and sold the size S.
Last year a built a LCFS947 size L for myself. I really liked the bike and I like the long reach That why I sold it and built a new LCFS958, in size XL.
The LCFS 917 i just built for fun and I never tried it, I just sold it.
The AM831 will be exciting to ride. I have decided that I will keep 2 bikes for myself and sell 1. This will be a hard choice to make because I really love both the LCFS958 and the LCFS947, can the AM831 be better than any of them......
