Mmmm! Maxxis rubber. Plus size bikes are coming, like it or not. The one thing holding them back has been availability of aftermarket tire selection. Maxxis gets into the mix with their Ikon and Rekon Plus tires. Available in 27.5 x 2.8. Weight was not available but best guess is about 1000 grams. The Rekon Plus is designed for aggressive trails, the Ikon plus is more for hard pack. MSRP was unavailable.
