I have just purchased sliding dropouts for my commencal Absolut SX….

Spot the obvious problem…….
The caliper mounts are fixed (not slotted like most designs)- so how am I supposed to align the calliper to the rotor when I tension the chain?
My thoughts are – you don’t, the wheel can only be located in the middle of the dropout.
This brings me nicely to the next point – why do sliding dropouts exist at all for this frame – and why have I just bought some?!!
