(Even road.) Wider is definitely the new faster for the added traction, comfort, and confidence.
But it’s not so simple as just getting the widest thing available since more rim means more weight.
The short answer: It largely comes down to riding style and personal preference.Incremental gains led to pretty dramatic ones with the development of fat bikes, plus-size, and Boost hub spacing to accommodate the extra girth.That’s been great for performance—traction and ride comfort keep improving, while manufacturers continue to work on lighter, stronger tire casings—but confusing for buyers.Similarly, the M635 or even M640 might be a good choice if you plan to run plus-size tires exclusively.But for the weight gains and broadest versatility of tire sizes, I’d still opt for the M630.
