9 speed rings on ten speed bike

Bozabyka

I have a bike fitted with compact 34-50 Tiagra and ten speed chain and cassette.
I would like to take off the compact and go to a double.
Would my Ultegra 53-39 9 speed chain rings be compatible with ten speed chain and cassette.
I intend to use the compact crank with 53 - 39 is this possible?

Your 53/39 rings wont fit your compact cranks- the mounting holes are different, though you can buy 53/39 110bcd rings to fit your compact.

thanks Paul.
If I use my existing crank with 53-39
Will it work with the ten speed chain?

No problem.
