Overdrive 29 2 X

* Required Fields


The classic 29er hardtail — that’s the best way to describe our premier aluminum model. We’ve taken our strong and light aluminum 29er frame and increased the stiffness and handling precision by adding Boost 148 rear spacing and thru-axles front and rear. We’ve also dressed the bike in an envy-provoking parts package that includes a plush and confidence-inspiring RockShox Reba RL fork, strong Shimano hydraulic disc brakes, and a SRAM GX/NX 1x drivetrain that provides you plenty of granny gear for the ugliest of climbs, without the complexity of a traditional front derailleur system.

Thanks to its 29er wheels, cleaning tricky rock sections and log-overs is a whole lot less tricky on this big wheeler, and since you can never have enough traction — particularly on a hardtail — we went the extra step and equipped this Overdrive with our own Blanchard 25 tubeless ready wheelset.

My review of a diamondback Hardtail

Review by Jer Fort
Overall Quality

My review of a diamondback Hardtail. I love reading new MTB reviews but it seems like the reviews are lacking in one area.
There are hundreds of reviews of $6,000+ bikes with thousand dollar drivetrains. However, there is a lack of reviews of entry-level bikes and bikes that most people can actually afford. I just purchased a Diamondback Overdrive 2 29er hardtail.

For the price I don't know if you can beat what you get with this bike. For me the stand out points are: a solid, lightweight aluminum frame, a SRAM NX/GX drivetrain, a Rock Shox Reba fork (100mm travel), and the WTB Nine Line tires. If you tried to build this bike yourself and bought all the parts separately you wouldn't be able to come close to the Diamondback price tag. It even comes with some really cool extras that most bikes don't include, like a mud flap, pedals, and a basic torque wrench and tools.

There are some parts and components that the typical rider would want to upgrade after purchasing this bike. The handlebars (740mm) are not wide enough for my liking. Even though the rims and tires are tubeless compatible, the bike arrives with tubes. Tubeless stems are included and this would be an easy upgrade. The lack of a dropper post is the most evident missing ingredient, but it is understandable that Diamondback does not include one in this price point. If you plan to do any longer rides on this bike you would want to upgrade the saddle as well. The tread on the WTB NineLine tires are geared for cross-country riding. If you were to use this as a trail bike you would want to have a deeper, more aggressive tread pattern. See my list of Good, Better & Best Tires here https://www.zionbikes.store/extras

Putting all that aside the most important question is how does it ride? The Rock Shox Reba fork has only 100mm of travel. This bike is not designed to take down rocky, technical terrain. It is very much geared towards cross-country riding. I bought it to keep up with the high school riders on my local NICA team. As long as you stay on the trails that this machine is designed for it is an awesome bike, especially for the money.

Being a hardtail 29er this bike climbs very well and is very efficient. It handles smooth trails and light rocky terrain with ease. It climbs easily and carries momentum well. For a hardtail with more traditional geometry it descends remarkably well. If you are looking for a traditional hardtail you will not find a better one for the price. This would be an excellent bike if you are on a NICA team or if you just enjoy riding fast.

Strong as balls

This bike fell of the rack on the highway at 65 mph and all I needed was a new derailleur, seat, and grips. I was super impressed that the Blanchard rims were barely bent also

Impressive right out of the box

Review by Nickname
Overall Quality

This is my second Diamondback mountain bike (2010 Mission 3 is my other, also a great bike). The Overdrive is also my second 29er. The Overdrive 29 2 has the components, tires, and ergos to shred singletrack right out of the box (after an easy assembly of course). I put it together and took it out to my local trail and was very impressed. First ride was a 20 mile singletrack joy. The Overdrive will be my primary trail bike with the Mission reserved for technical riding (think Moab). The only change I plan on making is using the included valvestems to convert the wheels to tubelss. I also used my clipless pedals instead of the included platform pedals. Great price, great bike, easy assembly. Ignore the haters and pompous bike nerds, Diamondback provides serious bikes that shred! Get one and go ride!
