I want to make my Giant STP a singlespeed and use TruVativ Luftalarm cranks. The Giga Pipe BMX bottom bracket has adaptors for a "Euro" BB, and it is my understanding that this is the same as a MTB BB. Is this true? Also, I want to use a Gusset 1'er SS conversion kit and was wondering if anyone knew that it will work on a 8-speed cassette and/or accept a 1/8" chain.
