The Xentis Squad 2. 5 Clincher Carbon Wheelset is the right choice when your job description, group ride expectations, or personal preference indicate that you have one role: climbing mountains on a bike. All winter long, you live like an ascetic monk while your rouleur buddies get chubby. Sugar cookies' No thanks, just some fresh celery, please. After all, you have to carry anything you eat today up the hill tomorrow. When it comes to your wheelset, you expect the same rigorous standards toward weight. The Squad 2. 5's claimed weight of 1,174 grams and barely there rotational mass mean it's the only wheel that truly understands the sacrifices you make to climb well. It also understands that what goes up must come down, so it's dedicated to keeping you safe on fast descents. The full carbon brake tracks behave more like machined alloy, stopping with consistent, confident force in wet or dry conditions. They also resist wear better than your typical carbon rim and don't even require special pads, so you can eschew the manufacturer's kid glove carbon brake pads in favor of that super light model. Please note that Xentis recommends a rider weight limit of 220lb 100kg.
