Diamondback Response Sport Mountain Bike Review


Diamondback mountain bikesThe Diamondback Response Sport Mountain Bike is the latest hardtail mountain bike in the Diamondback range.  Unlike full-suspension mountain bikes, the Diamondback Response Sport Mountain Bike combines utility with hardtail performances.  That makes the Diamondback Response Sport Mountain Bike perfect for many different situations like cruising around the neighborhood, gravel trails or even just around town.

Pros and Cons of the Diamondback Response Sport Mountain Bike

Since the Diamondback Response Sport Mountain Bike is made of aluminum, it is both lighter and stronger than bikes made over the last decade or so.  The brakes are quite strong and like a lot of other offerings from Diamondback it looks incredibly sharp.  The shifting gears are obviously entry level, and the tires feel somewhat on the heavy side but still acceptable.  The biggest downside to the Diamondback Response Sport Mountain Bike is the front shock, which barely feels like it offers any absorption at all, yet it doesn’t feel like it will be likely to break.

Overall, the Diamondback Response Sport Mountain Bike is a great bike that has mid-range components and a nice high-end frame.  It arrives well-packaged and is quite easy to assemble, but you should count on spending a full afternoon setting everything up correctly if you decide to not take it in for a professional tune up before you hit the road.

If you plan on doing any serious track riding with this bike, you may want to think about upgrading the pedals.  The included platform pedals are ok if you are simply riding around town and on local park trails, but are somewhat lacking for more serious tasks.  Another upgrade you could see a lot of benefit from would be to add a high quality suspension seat post.  This will give you some lighter weight as well as soften some of the rough bumps you will undoubtedly feel thanks to the subpar front shock absorber.
