The names DTR and STR tell you where they go and what they do.

DTR stands for Down Tube Right side entry.

STR = Seat Tube Right side entry.

This side-loading design is a great match for our Mandible cage and was developed over a two-year period, including testing in MTB World Cup competition. DTR fitment is like our proven Other Sideloader. STR is like our SideLoader.
