Which is lighter, the Saucony Triumph 20 or the Triumph 21?

Neither by a meaningful margin. Both weigh about 9.7 oz in a men's US 9.

Do the Saucony Triumph 20 and Triumph 21 come in the same widths?

Yes. Both run in D, 2E for men's sizes, so a width that fit in the Triumph 20 carries over to the Triumph 21.

How do the stack heights compare?

37 mm heel and 27 mm forefoot on the Saucony Triumph 20, against 37 mm and 27 mm on the Triumph 21. Same platform under both.

Is the Triumph 21 still the newest Triumph?

No. The Triumph 22 replaced it in 2024, so the Triumph 21 now sells as an older model and usually below its $160 list price.
