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.
We’re offering to build these wheels two ways. You can go with a budget friendly QR Formula MTB series 6-bolt disc hub laced with black spokes, or you can upgrade to a QR Shimano Deore 6-bolt disc hub set, (M525 series) with DT Swiss black stainless spokes. Both rear hub options have a Shimano HG compatible freehub, which is to say that they are Shimano MTB cassette 8/9/10/11 speed compatible. These wheels are built with 32 spokes front and rear, laced three cross with 12mm brass chrome plated nipples.
These wheels will feel solid, which hopefully will lead to confidence inspiring performance out on the trail. Don't let the overall wheel set weight steer you away; the rims, nipples, and spokes are all light weight given their performance capability. The hubs are definitely on the heavier side of the spectrum. Shimano Deore hubs do a lot of things well, (function, durability, maintenance, etc.), but they're just not the lightest hub set out there. That's okay though. These hubs will hold up, and over the years you may find yourself forming a bond with them. Hopefully in the meantime, you'll appreciate how good of a deal this wheel set truly is. Thanks for looking.
