Description

Tom Ritchey rides about 10,000 miles (16,000 km) per year, mostly off-road. Combine that with more than 50 years of crafting bicycles, and it’s no wonder that the Outback is an icon in the gritty world of gravel and adventure cycling.

Standout features for this edition of the 2025 Outback include internal routing for a dropper post, a rack mount on the fork crown, and internal dynamo routing. Aurora and Winter Sage colorways offer riders more options to style their ride beyond the bike’s existing practical and adaptable features, but the “big” news is, this Outback also comes in size XXL.

Bikepacking, road and off-road, you name it…the Ritchey Outback is designed to do it all.
