Tioga originally made the classic Comp3 pattern years, they were the tires of choice if you raced. For a long time the tires were available only in 20" & 24" sizes, but if you rode 26", only the Cheng Shen's knockoff were out. There's were okay, till you hit the brakes and wore out the the tires in a month. Now Atomlab , has step in to fill the void for those who tires that stand up to the daily abuse of their dirt riders, who who didnt want run a heavy DH/FR tire anymore. There will be sizes available 26"x2.1" (summertime) and 26"x2.3" (in March). Look out for them.
Also for those who didnt know Atomlab also make BMX parts, for example this lightweight 13 butted tubing.
