Want to see what the 27.5+ craze is about without buying a new bike? If you have a 29er, I have good news: All you need are wheels and tires. The outside diameter of a 27.5+ tire is close to that of a standard-width 29er tire. The bad news: You need wheels and tires.

The biggest issue with converting a 29er to take these plus-size tires, which are sized from 2.8- to 3.25-inch-wide, 27.5-inch-diameter tires, is clearance—which is why the 2.8-inch-wide WTB Trailblazer TCS Light is a good place to start. I've converted several different 29ers with this tire, including a Specialized Camber, Specialized Enduro, and BMC Trailfox.

About those wheels: Wider rims are required to reap the benefits of being able to run lower tire pressures, and we've found that those measuring 38mm to 50mm internal width work best. We like WTB's tubeless-ready Scrapers ($150 each), and you can lace them to your favorite hubs. For a prebuilt wheel, we recommend Stan's NoTubes ZTR Hugo 52mm wheelset ($729 per pair).

Price: $68 each
Weight: 921g (pair)
