Diamondback brought out a pretty decent bike in 2016/17 called the Release, and a few variants of it (Catch, Clutch, Release 29, carbon frame). It’s good. It has an excellent linkage. Compared to MY23 bikes appearing now it’s getting out of date.
Sometimes it has been an excellent value. They had a corporate reward discount and the password was an open secret. The bottom spec version they sold via Performance/Nashbar in 2017/18 was a screaming unbeatable deal when it went on clearance. You can get a discount now through IMBA, I think.
They have a good hardtail called Sync’r. They brought out a new enduro model called Mission but I have heard little about it.
They have a new short travel bike in the pipeline but it’s Covid-delayed. Going down the rabbit hole on that I learned that the guy running the company really believes in the Atroz as a low price entry level bike although few people now give it the time of day due to its very basic suspension design.
Eric Porter, who you can find on YouTube, rides Diamondback. So did Seth of Berm Peak though that recently dissolved for reasons unstated. I think Porter is an actual employee, or at least more directly involved with the company bike development, where Seth was sponsored.
