I bought the Abba Superbike Package 3.
For the high price, I expected a lot more.
There is a coarse thread bolt that holds the vertical bit to the rolling stand; my bolt was mis-located by almost 1/2 the bolt dia.
Of course, that prevents it from working (i.e. locking the pieces into place); so, I must be VERY careful rolling the bike on this stand as it very easily can fall off.
The front/rear extensions are practically useless; they send a strap which is supposed to pull the rear of the bike down (to lift the front wheel), but that whole arrangement is crap, so it is not being utilized either.
I cannot recommend that manufacturer.
