2022 Borealis Crestone Eagle

Specs, Comparisons, Reviews, Galleries

The Crestone is Borealis' flagship fatbike, from a company that specializes in fatbikes.

What we like:

  • Ultra customizable options with lots of variety based on your budget and purpose.
  • Fit up to 5"x26" or 4.5"x27.5 tires gives lots of options based on your needs.
  • Ultra lightweight, this is the lightest fatbike we've seen. Even the cheaper builds come in at 26.5 lbs.

What we don't like:

  • We don't own one yet ;)
  • They don't share standover numbers because of the customization amount, we would like to see a range at least. For shorter riders this is so important on snow.
