Mixing/Upgrading Shimano Components

Sorry I'm sure this has been posted many times but I can't find it on the search. I just traded in the Mountain bike for a road bike. Picked up a specialized allez but I want to upgrade the components.

Can I mix Shimano 105 Shifters with an Ultegra rear derailers?

Will 105 shifters work with Tiagra brakes?

Thanks,

Noob

You certainly can. My winter bike has Sora FD, Tiagra chainset, 105 RD, 105 cassette, Ultegra BB, Dura Ace chain, and R450 long reach brakes.

Yes you can. Just make sure you get a long cage rear derailleur if you have a triple or very large cassette.

My main bike has older 105 shifters, Tiagra crank, older 105 fd, sora cassette, modern 105 rd, modern 105 brakes dura ace chain, 105(I think) bottom bracket. It all works fine
