Bordeaux-Begles have completed the signings of Avenisi Vasuinubu, Yassin Boutemane and Damien Larrieu.
Fiji winger Vasuinubu had been due to play at the IRB Junior World Championship but the 19-year-old has now opted to accept a 12-month deal at Bordeaux.
Vasuinubu has impressed on the HSBC Sevens World Series circuit and will now look to establish himself in the Top 14.
Prop Boutemane has committed to the club for the next two seasons, having made eight appearances for Toulouse last season.
The 23-year-old back-rower Larrieu will make the step up to the Top 14, having missed out on promotion with Pau.
Larrieu appeared 22 times for the ProD2 side, including in the play-off final defeat to Mont-de-Marsan, and has agreed a year-long contract.
