Whether you are new to the trails or a seasoned single track rider, the Response series offers uncompromised performance without compromising your bank account. Combining the perfect blend of hardtail performance with rugged utility, the Diamondback Response Sport – which shares the same frame and several of the components of the pricier Response Comp is a value oriented build ready for any new rider or trail enthusiast.

At the heart of each Response is our rugged Diamondback 6061-T6 aluminum frame with formed top and down tubes providing strength and style with clean lines. A machined headtube adds strength and style while forged drop outs with a replaceable hanger add the finer touches. The components provide more proof of our commitment to providing you with the most appropriate package and value for your money.

A SR Suntour XCT 100mm travel fork with 28.6mm stanchions affords you a descent fork without all of the extra costly bells and whistles, yet still capable of climbing or descending your favorite trail. Also on deck is a set of Tektro Alloy Linear Pull brakes which are a light and simple solution to stopping your rig on a dime.32h Weinmann MX260R Doublewall rims laced to 32h MX260H alloy hubs combine to make a durable and long lasting wheelset.

The SR Suntour XCT crankset (22/32/44t) is a good match for the Shimano TX50 front derailleur, the Shimano Altus 7spd rear derailleur and Shimano HG20 7spd Cassette (12-28t). This combo provides more than enough gearing options to get you where you want to go when you want to go there.

Diamondbacks signature alloy SL318s stem and Oversize 31.8mm Mid Rise handlebar create the perfect cock pit while the SL309p Alloy Micro Adjust 30.9mm post and DB low profile All Mountain saddle ensure that you can pedal all day long.

The Response is available in XS (14"), SM (16"), MD (18"), LG (20"), XL (22") and offered in both Black or Red to suit your needs.

If a solid, reliable, and affordable all-purpose mountain bike is what you’re after; a Response is the one for you.
