Im looking at getting a Gary Fisher Mullet SS, and i cant find any info on the Bontrager Earl Singlespeed cranks or which bottom bracket is used with them (or at least the interface). Im assuming that it is ISIS or Howitzer like the Big Earls, but im not sure so im asking you guys.

Also, does anyone have any personal experience with these cranks? (Again Im assuming they are simply a singlespeed version of the Big Earl's)

P.S. The frame has an eccentric bottom bracket if that affects what bottom brackets will work.

Thanks for the help!
