Cheapo digital calipers here, good enough for bike stuff. £3.12 delivered.
Just received these. They don't exactly give off the impression of a precision instrument, which is disappointing for something that cost £3.12 to be send from Thailand. Everything is made of plastic.
They measure a 30.9mm seatpost I had to have as anywhere between 30.6 and 30.8mm. Should be good enough to tell the difference between parts, rather than accurately measuring the sizes of things.
It’s good that you identified something they are able to do. I’ll save my £3.12 though since I’ve been able to tell the difference between a stem and a seatpost most of the time...
