The Sun MTX39 disc rim is about as serious as it gets. The rim has a super tall, super wide profile. Using them to build a bicycle wheel is sort of like using an I-beam for a handle bar. The rim has a welded seam, single stainless spoke hole eyelets, has a crazy strong profile design, and is finished to an incredibly exacting standard. Given the MTX39’s rim strength, and just how precise it is finished, we’re able to build and true wheels with consistent spoke tension down to 3 to 4 thousandths of an inch. Ready for a radical miracle? Just a walk in the park Cougar.
