What goes up must come down. The good news is, that's the goal with the LG1 EN 27. 5in Boost Wheel. We're running downhill lap after lap, and the LG1 Enduro wheel can handle it all. It's born from a strong racing heritage, and it's tough enough to last thanks to all-aluminum hubs. Plus, it's an affordable option that won't break the bank, which means we can continue treating our gear like tools, not jewels. With a 30-millimeter internal rim width, these wheels are best utilized with tires that are 2. 3 to 2. 6-inches wide. With these wheels, we'll feel confident picking up the pace on our race to the finish line.
