British cyclist Matt Walls' superb Olympic debut continued as he won a second Tokyo medal with silver in the men's madison alongside Ethan Hayter.
Walls, who won gold in the men's omnium, again finished on the podium in Saturday's 50km race where points are awarded for 20 intermediate sprints.
The British pair held the gold medal spot after 10 sprints, having made a strong and consistent start.
They faded in an open race before a breathless final sprint secured silver.
It was still not enough to overhaul reigning world champions Denmark, who won gold.
Walls, 23, and 22-year-old Hayter won Team GB's 61st medal of Tokyo 2020 - and a Games-high sixth on the cycling track - to leave them two short of the London 2012 total (63) and six short of Rio 2016 (67).
Jack Carlin and Jason Kenny still have the chance to increase the tally after reaching Sunday's keirin quarter-finals.
In the women's sprint, Katy Marchant was eliminated after losing the opening two races of her best-of-three quarter-final against Hong Kong's Lee Wai-sze.
With double points available in the madison's last sprint, Walls and Hayter - who are housemates as well as team-mates - attacked early and maintained their advantage to pip France to second place overall.
"I was cooked halfway in but we had a bit of gas at the end to finish it off. It was everything I had," said Walls, who had a broad grin during his post-race interview.
Hayter added: "We set out on the front to try to get a head start. I think my legs started to go first because the first 100 laps were so hard.
"I started to suffer, then Matt started to suffer. But we recovered and finished with a flourish."
'A hugely impressively physical feat - analysis
Sir Chris Hoy, Britain's six-time Olympic track cycling champion:
Walls and Hayter threw everything at that and they should be very proud of the silver medal.
GB were leading early on, but kept chipping away for points.
A lot of these guys' day job is the road team, and they have that strength to do a relatively short race but at 50km per hour. It's a hugely impressive, physical feat.
