The 105SC should be an 8-speed series freehub offering <-- not right 100%.
IMO this is not correct, why? well 105sc, the one that is champagne colorish was a 7 speed hubset, Hyperglide and those hubs were 126 mm wide. No idea if they did 130 mm of those, because the sc part in the 105sc disappeared of the name at some point when they changed the thing to 8 speed I believe, and obviously you can't put an 8 speed cassette in a 7 speed 105sc hub.
If the hub the kid is talking about is this one...(picture) then he cant put an 8speed and up cassette in there, those hubs are 126 mm, the freehub body is too short. Darn shimano changed the darn hubs like 5 times if not more in the last 15 years, just idiotic.
