Special order items take longer to ship

We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

The Diamondback Mason 1 is a hardtail bike for the trails. This sturdy hardtail is built of aluminum to travel along the dirt, roots, ups, and downs while the lack of rear suspension makes it even lighter for lots more fun.

Product Reviews
Rated 5 out of 5 by from Very Capable - Steal of a Bike - Great Store Have had my DB Mason for about a month and been on half dozen rides (on blue & black trails) and hasn't disappointed yet. My job commitments are the only thing preventing me spending more time on the trails on this bike. Good geometry (I am 5'`0" and bought Med. frame), good wieght )not heavy at all), solid components and exactly what I was looking for except the 27.5+ tires which have turned out to be a bonus. Lots of fun and expect to have this bike for years.

Rated 5 out of 5 by from Great Bike!!! This bike is a serious beast. Looks even better and more capable of some legit mountain biking in person. I had to look for a while to find a good bike at a decent price that was in stock. So glad I was able to find and purchase it.
