3.3 is just the model number indicating that it is for a triple. These were originally designed as 9/10 speed. There was also a 2.2 version that was a double, and a 1.1 that was a single ring ("1x" was not really a term back then).

They are all basically the same cranks. The 3.3 had (I assume) 22/32/44. The 2.2 was the identical crank, but with 24/36/bash-ring . the 1.1 was again the identical crank but without the holes tapped for the small ring. The middle/big positions had 32/Bash.

Perfectly good stuff. I have been running the OCT version of these (pretty much the same thing but with hollow arms to save an angle-fart's worth of weight) on my AM bike for about 9 years. I replaced the BB once. Mine was the 2.2 version, I now run it 1x.

The only "gotcha" is that it could have worn out rings and BB.
