@Markbw Thanks for reaching out!
We are constantly re-evaluating the Co-op Cycles line to make sure that we offer the best range of bikes for riders and all the different ways they want to get out on their bikes. This year, the DRT 1.3 is being retired in order to make room for a balanced range of hard-tail mountain bikes with standard and plus tires.
If you're looking for a step up from the DRT 1.2, please check out the new Co-op Cycles DRT 2.1. It has a SRAM SX 1x12 clutch derailleur, is tubeless-conversion ready, and comes with a dropper post.
Hope this helps!
