We're a mission-driven bike shop based in Colorado. Every sale helps refurbish and donate bikes to those in need through Bicycles for Humanity Colorado. Each item has been professionally inspected, thoroughly cleaned, carefully refurbished, and is ready for immediate use.
The 2023 Mason Definition is one of those rare aluminum road bikes that genuinely turns heads — and this 56cm example, finished in a striking pale sage/cream colorway with burgundy decals and warm bronze/copper headset and seatpost collar accents, looks the part of a custom build rather than a production bike. Mason's reputation for precise, ride-focused geometry shines here, and the component spec is genuinely impressive: wireless SRAM Red eTap HRD shifters and hydraulic disc brake calipers handle shifting and stopping duties at the top of the SRAM hierarchy, while a SRAM Force 2x crankset keeps the drivetrain honest and robust. Prime Attequer Carbon 700c wheels keep the weight at a nimble 18.1 lbs, and ENVE carbon drop handlebars add a premium touch at the cockpit. Wolf Tooth seatpost clamp and stem cap round out the thoughtful details. Condition is excellent with only very light signs of use — paint, decals, and those distinctive copper accents are all clean and vibrant. This is an ideal choice for the performance road rider who wants a distinctive, well-specced machine that stands apart from the carbon crowd.
