Hi !
general question.
I have a 100Mbps network but in two sockets in the network I have plugged two 10Mbps hubs.
Will I have a bottleneck problem? Is my network 10Mbps now?

You will have a bottleneck. Anything going through the hubs will be at 10 Mbs and at half duplex as well.
Hubs are dumb devices that receive data at one port and send it out on all the others unlike a switch which only sends data out on the port is connected to the destination computer.
You would be better of with a switch.

Just because its a hub does not mean it runs in half duplex. Plenty of 10mb hubs I worked with did full duplex no problem.
The hubs will not cause a bottleneck with pcs connected to the main switch. PCs connected to the hubs will be slower since they have less bandwidth.
The real issue with connecting hubs to switches is transmission errors. Hubs tend to generate RX and TX errors which the switch will log but ignore. Those can cause further delays with the pcs on the hubs.
Using switches only is the preferred topology these days.

Oh... That means that the whole network speed will not slower down, only the PC's on the hubs... right?

that is correct. switch to switch port is not effected.
Knowing the correct answer and giving a correct answer, are two different things
