My youngest has a 20 scale plus. Tyres are ~ the same weight as a 20″ 2.8 Specialized big roller and once the 16″ tubes arrive and I try mountain them ghetto tubeless I think they will be no more draggy than regular sized oem tyres. So, 24’s probably iro 850g, so twice a rocket ron, but sub 100g heavier than the tyres on that MX24, but a tremendous amount more traction I’d wager.
FWIW, I did a photoshop layup of a 24 scale plus, 24 scale RC, Commencal meta ht 24 and a Spawns new Yama Jama. I actually really liked the Scale’s bb drop and much lower standover than the other bikes as my guy is on the small side of things for a 24 wheel. A little longer in the chain stays as it still has a welded mount for a… wait for it.. kickstand..
also a little steeper but that’ll get fixed adding a sus fork and still slacker out the box that other major brands offerings (Cube, Orbea, Giant etc who are still knocking out 72deg bikes)
I’d share the image, but I didn’t save it for some unknown reason.
I’m one for changing things though. My kid 20 has carbon bars, short stem, 122mm cranks with 30tn/w, zee mech, saint shifter and 11-36t cassette, avid bb7’s.
If I can get a scale 24 for the bigger kid i’d do the same and add an air fork.
As is, out the box, it is still a pretty well spec’d and great looking bike with few better than it for less money.
