Frame Size

The Sorrento bikes feature a heat treated and butted 6061-T6 aluminum frame. The frame and the SR Suntour suspension fork help maintain control when trails get bumpy. Users remark about how few limitations the build offers on the trail. Some deem the replaceable derailleur hanger necessary for rougher hikes.

The heat treated aluminum frame makes for sturdier lighter ride. It says something when Diamondback uses the same treating process for its $$$$ bikes as well.

Brake Type

The Sorrento and Hard Tail bike lines feature Tektro Alloy Linear or V-Line pull brakes. Riders state that the brakes are suitable for beginners or average bikers. While advanced bikers may desire more responsive brakes, you can replace some parts. Specific braking upgrades can be overkill, though.


Sorrento bikes feature Shimano EF-51 Easyfire 7 speed shifters. More advanced riders complain about the limited gear shift. The gear doesn’t serve as an issue for beginning bikers wanting to hit the trail.


The Diamondback Sorrento line comes with 32h Diamondback XC260 wheelset. The wheelset also comes in other sizes like 26″ and 24″. The rims are also double walled, which should make the bike sturdier and able to take on more. The mountain bike also offers quick release wheels. The wheel size and build offers less rolling resistance without giving up maneuverability.


The Sorrento use Chaoyang Hornet tires. The tires for the 27.5 measure out to 27.5″ x 2.1″. They are very beneficial tires for people trying to ride with tubeless ready bikes. The tire sidewall gives the defense against cracks and bumps on mountain trails.

What We Like

The Diamondback Sorrento offers an excellent build for bikers on a low budget. The wheels offer a cushy ride over hiking trails. The frames are lightweight, but also provide a significant amount of control.

The bike works well for beginning or entry-level riders.


  • Looks great and excellent lightweight aluminum frame
  • Varied sizing for younger and older bike riders
  • Great, affordable low price

What We Don’t Like

Reviewers and users have cited a couple of significant issues. Despite how effective the bike is, Diamondback made this bike more for early bikers. The bike has a seat post that discourages longer bike rides. The bike requires a bit of constant maintenance.

Diamondback didn’t build this bike to be a trail bike that is used daily. Certain bike parts reportedly break and don’t hold up under more rigorous conditions.

Users have also complained quite a bit about the brakes and how they break after a few uses.


  • Pedals made from cheap, easily broken plastic
  • Weak chain
  • Not as durable as other bike brands
  • Still needs assembly after sale

The price tag makes it affordable and it has some great benefits for the price.
