And as long as it doesn't have the 15mm inboard offset (I don't think applies to anyone except some Dahon models), a swap to anything else should be easy.
I'd be interested in hydraulic, heard great things, but that's an area where I would only go with a known and quality brand, as cheap brand hydraulic stuff leaks and is not durable, as a rule. I've read great things on here about Shimano (Deore?) hydraulic calipers.
I think it is the same basic concept; as the lever is pulled, it rotates a plate with location track for bearing. The track has a variable depth leading to a piston transltion movement. however, on the spyre, it is twin pot rather than a single side and they have seals and bearing rather than bushes to smooth the mechanism
My daughter runs trp
HY/RD caliper and they work well. only issue is the big hydrau reservoir makes the caliper adjustment a bit fiddly because the hex driver does not fit well (need a cut down one)
My son runs clark clout junior which is a copy of the cheaper shimano hydrau and it works well; you can see it was re-engineered and manufactured to be inexpensive but they are fine if you are not after the lightest strongest setup with all bells and whistles.
Actually these clark clout could be another good option for OP. ~50€ per kit so 100€ total and you can offset cable housing cost
I run sram rival and they work well; I boiled them once but I was using them on a steep offroad downhill (solution was to go for 180 rotor on front)
I now run hope RX4+ 4 pots calipers which are very strong and sometime "overbraked" but I prefer to be able to lock the wheel and adjust braking technique to tyre grip rather than running out of brake (motorsport old habit).
