In no particular order:

Reason #1 - Convenience. When you need a part ASAP to get to work, having an existing Amazon order that you know will drop in and fit without so much as having to adjust your brakes is a big plus.

Reason #2 - Quality. The wheel is a 26" mountain bike wheel. Serious riders don't hardly ride these anymore - they are typically found on toy store level bikes. Quality offerings from legit brands are far and few between. I knew the product I ordered had a certain level of quality - certainly better than the non-sealed single wall OEM wheels I replaced with my first purchase.

Reason #3 - Continuity. I always keep parts the same when possible. For example, the front wheel of this order can mount with a snow tire for when I need a change on a snowy day, or a regular tire for when I might have to leave for work but find the front tire flat. If the front rim cracks, I'll have an instant replacement. If the rear rim cracks again, I'll have a replacement if I take the front apart. Same with spokes and hubs and such.

Reason #4 - Value. I have no idea how they sell two wheels, complete with shipping, skewers, and a brand name freewheel, at the same price as two years ago - $99.

Reason #5 - Abuse. The bike is a commuter and an old 3x6 speed beater with a milk crate on the back, and it takes a beating. All kinds of roads and weather - 34 miles, 5 days a week. Putting nice anything on it wouldn't make a lot of sense, so I don't.
