yea i dont see an issue with getting a 2.4 tire in it..
i have a rara 2.25 and it has a ton of room.. it almost looks funny how much room there is.
i like the 057.. I am 6'2" and i am feel i am between frames so it is a bit on the smaller side other than that it is a climber.. turns fast.. and stiff (i got the 142x12 rear axle and a 15mm front axle) I am not running tubeless but run about 33psi in it.
