Elynor and Zoe Backstedt celebrated a stunning family double victory at the prestigious Gent-Wevelgem races in Belgium.
The teenagers, daughters of former Swedish pro rider Magnus and ex-Welsh and British champ Megan, have again shown why they are two of the hottest prospects in British cycling.
Pontyclun-based Elynor, 17, won the under 19 race after launching a solo attack before crossing the line 16 seconds ahead of the chasing pack.
And younger sister Zoe, 14, claimed an even more emphatic win of three minutes after also making a solo attack on the cobbles at the end of the first lap.
Gent-Wavelgem is one of the most important one-day races on the world calendar having been held annually since 1934.
For a family to dominate the junior races in such fashion is a huge achievement.
Cardiff’s Luke Rowe took part in the senior men’s race on Sunday finishing 18th for Team Sky after a typically gutsy display.
The duo have joined Storey Racing this season, the venture set-up by Britain’s multiple Paralympic champ Dame Sarah and her husband Barney.
Elynor, who won time trial bronze at last year’s World Junior Championships, was competing for British Cycling in Belgium.
Zoe had lined-up for Storey Racing in an age category she is eligible to compete in for two more years.
