I thought the SiSL were lighter?

SiSl are more extensively machined than the SL, around the end of the crank where it bolts onto the axle for e.g. and are therefore slightly lighter.

The SiSl2 take the machining further.

is there a crank with just SISL written on it? I haven't seen one... I think.

Edit: ah yeah I get ya. I suspect those 'sisl' cranks are actually jus the new Si crank but with a different graphic.

Edit2: oh wait, no. Apparently in 2013 they were still making SISL and SISL2 cranks. So the crank with 'SL' written on it and the crank with the new SISL graphic are actually the same.

Si old - 99pc of them are silver but the occasional ltd edition black ones kick around
Si new, with new Si logotype. Black / Purple
SiSl - graphic is just a large 'SL' or for 2013 'SISL' in the new logotype. Black or Silver
SiSl2 - all black, maybe some ano versions around

Is the lineup possibly by weight / stiffness
