Close back rounded vowel to Voiced uvular fricative
The shift from the high back rounded vowel [u] to the voiced uvular fricative [ʁ] is a form of retraction and consonantalization, often occurring as a sub-phonemic effect or triggered by historical shifts in the point of articulation.

Language Examples
two [tʰu]→[t͡ʁu]— Sub-phonemic affrication where the backness of [u] triggers a uvular fricative release in some speakers.
Historical [ʒ] before [u]→[χ/ʁ]— Back vowels like [u] contributed to the retraction of historical palatal sounds to the uvular/velar region (e.g., development of the Spanish 'jota').
