If you happened to purchase a low to mid end mountain bike with wheels built using Mavic's XM119 disc rims, you may have lucked out. But historically, they were used as a bargain basement rim option to build in to inexpensive wheels on high end bikes. Does that make any sense? Probably not to you or me, but if you're selling a high end bike and you know the wheels will be replaced soon anyways, maybe it does.
Prior to Mavic's current 4, 6, and 8 series rims, they produced their 1, 3, 5, and 7 series rims, (and 8 series UST too, but come on...). Each sequentially higher series offered more rim tech, and quality. As you can surmise, XM119's are at the bottom. Does that mean that they're bad? Not at all, they're still a quality rim, but they're pinned, without single stainless eyelets, or any other rim tech/feature/or noteworthy material. It's just a really nice, basic rim. But they do hold up, and with a 19mm inner width, will work well with a decent range of tires. Should you buy this wheel set? Entirely your call. Should you watch this short but sweet rock climbing video? Absolutely.
These wheels are built with reliable, quick release, black ano, Shimano Alivio M475 series alloy 6 bolt disc hubs, that will work with Shimano MTB 8/9/10/11 speed cassettes. You can run a 6 or 7 speed cassette on them as well, but you'll need to source a 4.5mm spacer (6 speed), or 4 mm spacer (7 speed) that is compatible with your cassette's function.
These wheels are built with quality DT Swiss black stainless steel 2.0mm (14g) J-bend spokes in a 32 hole, three cross configuration front and rear. These spokes are an upgrade over most "new bike" spokes. Small details make big differences with regards to spoke wire, and even though there are lighter weight spoke options available, these straight gauge spokes still feature top quality stainless, with a precise finish that allows for precise wheel building.
Overall, these wheels do in fact represent a solid XC wheel set option, capable of fast, aggressive riding, and will hold up to moderate impacts. And at this price, they are an unbeatable deal. We're not joking around here.
