Replacement for discontinued Schwalbe Tyrago
Do you mean a CX tyre having similar tread to your Tyrago? Do you mean performance-wise? Same brand? Why don't you just buy a new tyre of same brand and model (Tyrago supersedes Tyrago)?

The question's a bit vague. Most CX tires produced recently are pretty much well-performing and supersedes Tyrago (or even better than it), though it depends on its specializations.

Anyways, I'll hand out some examples of CX tires with similar, angled treads/knobbles: (might give you insight on what you want)

Michelin Protek Cross - very fast rolling (road) but slippy in muddy conditions.



Michelin Cyclocross Mud 2 - fast rolling (road), more traction, a bit mud-clearing


Bontrager CX0 - pretty fast rolling (road), okay traction, not that mud-clearing, side knobs for cornering


Maxxis Mud Wrestler - okay rolling (road), nice traction, very mud-clearing


Continental Cyclo X King - meh rolling (road), mud-biting traction, mud-clearing


Hope you can sort that thing out. I myself use something like the Bontrager CX0 as I both go on long road tours and off-road sessions.
