Took it out on a day trip and found the bike to be great on the road as well as on a few trails, quick detachable front tire great for transporting the bike in a car. Overall, very happy with this purchase.
This bicycle will cost you a good 499.99 at the stores or even more at bike shops.
Purchased this bike at Amazon for 399.99 as a special price sold by Amazon.
Its a great bike and easy to assemble. 95% of all parts was already assembled.
All i had to do was insert the quick release rod to the front wheel, install the handlebar and install the front wheel to the fork, secure it with the quick release.
I had to adjust the breaks and install the pedals. I checked the derailer and spun the wheel for the first gear nice and smooth.
You will love this bike even its steel but light weight.
My initial observations:
- The bottom bracket bearings were damaged. The cranks did not spin freely and there was considerable resistance, even with the chain off. Upon disassembly and inspection it turned out that the BB is not a sealed cartridge (as specified on the Diamondback website for the 2014 Response), but made up of good old caged bearings. See picture [it looks like Amazon removed the photo when I edited the review]. This is not acceptable for a modern $500 bike.
- I share the concerns of another reviewer about the rotors being difficult to center. My bike arrived with the break pads fallen out of the front caliper (they are magnetic) and it was pure luck that they were still in the partially torn-up box. I found instructions online for how to replace them, but the disk touches both the pads and the fork mount adapter. The adapter cannot be moved. I had to put the wheels in slightly tilted for the disk to spin freely.
- The chain had come off in the front and was pulled into the gap between the chain rings and the bottom bracket. It took a while to get it out and I am not sure if it had not suffered some damage from this. I definitely scratched the paint in the area.
- The chain has too much slack and, especially when on the small front chain ring, constantly clanks on the chain stay. I don't know what to do about this yet. If nothing else, it will need a chain stay protector.
- The front brake cable is bent in a 90 degree angle somewhere in the middle - not good for a long cable life.
- There are some scratches on the chain stay and crank set on both sides, possibly from the same impact that damaged the bearings.
- There was a left-over part that I could not identify until I visited the Diamondback website and reviewed the mountain bike assembly instructions. It is the "bleed block" that had fallen out of the front break along with the pads and that is not needed to operate the bike.
If no other issues surface, this still makes the Response an affordable entry level-bike - if you are ready to invest a bit, or you are handy and own the required tools.
I ended up doing the BB replacement myself. It took me over a week to learn everything about bottom brackets, determine the correct size (Shimano UN55 73x122.5mm worked), buying the tools (crank remover and a Shimano BB tool) and the bottom bracket, and completing the job. I measured 73x24.5 for the bottom bracket but did not find one with these dimensions, so I went with the next-smaller size. I used a pipe wrench to remove the lock ring that is not needed with a sealed BB cartridge). I had to start from scratch with the gear adjustment because the front gears were not at the same location as before. This took longer than installing the BB.
Yesterday was a cool but sunny December morning here in Massachusetts. I took the bike out for the first spin on my local trails. It performed well and I felt much stronger on pretty much all terrain than with my old 26" bike. Being high above the ground is good when trails are wet or flooded and it allows me to better navigate the trail ahead. The tires are big and wide and have good traction on steep inclines. The bike is stable on faster downhill sections. I am reasonably happy with the purchase.
Update 2016: I like the bike and I am upgrading my rating to 3 stars, up from the original 2. I have since learned how to adjust the breaks (after I friend told be that they were outright dangerous), and I have also noticed that the brakes are reversed - the rear brake handle is on the left, which can be outright dangerous as well if you ride different bikes. I don't think I did this - they must have been swapped at the factory. I recently replaced the plastic pedals. The original ones broke after hitting rocks and trees. I also added climbing bars. The front fork is now the weakest components and will be the next replacement.
Like all new bikes you will have to constantly tweak the bike to your liking. If your new to bikes it may be a good idea to get someone that knows what they are doing to look over the bike before you go riding to ensure its set up right.
Regardless so far I'm satisfied with the bike, I will update my review in a month or so to give you more details.
My husband is tall and he find this bike to be extremely comfortable. It has gone on many trails of all levels of difficulty and we can say that it is a durable and sturdy bike!
It wasn't the easiest to put together, we actually had a friend who is well versed in biking help us assemble and make all the adjustments. My husband added some different pedals and a different seat.
Overall he is extremely happy with this bike
