Diamondback Release 5C // Bike Review

Apr 2018 · Spencer Johnson

In the last five years bike standards have jumped up substantially—to the point it’s hard to buy a bad bike. We should consider ourselves lucky that the bike industry is full of passionate companies all creating designs that have their own flavor. Now days, it is often less a question of “Is this bike good?” but rather, “Is this bike good for me?” Nearly every combination of wheel size, travel and suspension platform is available, so it’s simply a matter of determining how each one of these factors matches with personal preference and riding style. Originally released in 2016, Diamondback’s Release is perhaps best classified as a decently slack, mid-travel bike designed for all-around ripping. With the 2018 model, Diamondback has now taken the Release to the next level: carbon. They’ve stuck with the bike’s signature Level Link suspension—a game-changer from their previous platforms—and a nearly identical geometry. Every notable and lovable factor of the original Release still stands, the bike is now just lighter and noticeably more stiff.

Diamondback Release Carbon is the Level Link bike you hoped for - and it's affordable

Oct 2017

Considering that the aluminum Release 27.5 is already Diamondback’s best selling trail bike, it’s hardly surprising to see that two carbon models have just been announced. Diamondback is being pretty competitive price-wise with these bikes; the base model Release Carbon will sell for $3000 USD, and the higher-end 5c model offers pretty good value for …
