When we're riding on wheels as strong as the Union 1/1 27. 5 Super Boost Wheelset there's no grimacing after casing a huge table or gap. These dependable Union rims are laced to equally impressive Industry Nine hubs to give our bikes one of the best rolling options in the industry. The hoops are specifically made to take up to a 2. 7in tire, so we're testing the waters with plus-tires while rolling through huge rock gardens and chunder-filled shoots with confidence.
