Before carbon hoops became mainstream racing fare, start lines across the world were peppered with Mavic's fast-spinning and nearly bombproof Ksyrium aluminum hoops. With metal now more often relegated to training wheel status, generations of Ksyriums still find use grinding out epic base miles and waiting patiently in the wheel pit while the carbon Cosmics get the nod on race day. The Mavic Ksyrium Pro Carbon SL UST Wheel brings the Ksyrium name right back to the pointy end of the racing game with an all-new hub design and a full-carbon rim that's backed by Mavic's trademark reliability and clocks in as the lightest of the tubeless ready Ksyrium line. Mavic launching a full-carbon rim is a big deal in the bike industry. The company is nothing if not a stickler for safety and has long been a lone standout with aluminum-bedded rims in its carbon wheels, citing concerns over safety and braking performance with full-carbon rims. Mavic claims to have finally cracked the braking power and heat buildup puzzle with its iTgMAX rim construction, which uses a proprietary resin to resist heat buildup and reduce chances of tire blowout or rim failure. Paired with Mavic's laser-etched braking surface, this technology results in exceptional braking reliability across wet and dry conditions for a claimed 48% reduction in stopping distances compared to other carbon rims. Mavic always places a premium on braking and just as it has done with revolutionized aluminum braking surfaces with its Exalith design, we see no reason why they wouldn't do the same with carbon. Mavic uses 3K carbon fibers to shape the rims in a bullet-nose profile. While the wheels aren't specifically called out as "aero," Mavic constructed it specifically with climbing and endurance riding in mind, so the 25mm-deep sections are dependably stable while riding in crosswinds and tackling twisty, long descents, and they'll provide a touch more radial flex to dissipate bumps. Mavic also paid close attention to t...

Maine ocean islands provide the only nesting sites for Atlantic puffins in the United States. Eastern Egg Rock in the midcoast region, Seal Island and Matinicus Rock at the mouth of Penobscot Bay, and Machias Seal Island and Petit Manan Island off the downeast coast provide habitat for more than 4,000 puffins each summer.
