The lightechs has awesome and easy adjustments. According to the instructions there is 6 position on the trac system plus you can could swap the foot peg and mounting screw which gives you a total of 8. I got kind of confused because I thought that would make it 12 but when you swap the foot peg and mounting screw there is only two holes that you could mount it to.
I have mine set on the second to the lowest setting (I'm 6'0'' with a 32" inseam) and it seems to be the most comfortable with canyon and street riding for me. I don't feel cramped at all. For the track I like mine to be up and back which keeps you more in the tucked position.
There are very few aftermarket rearsets that I know of will place your foot position the same as the stock. Most will lift and sweep it back for track riding. If you put the lightech on the lowest setting on their trac system and swap the foot peg with the mounting bolt it seems to be very close to the OEM position if not the same.
I hope that helps.
