Diamondback Interval Carbon Flat Bar Road Bike

It’s not everyday that the most exciting bike in our offices turns out to be a flatbar road bike. Now, we don’t mean any disrespect…flatbar road bikes are fun to ride, comfortable and offer plenty of advantages… but they usually aren’t the bikes that everyone in the office crowds around to see. That is until the Diamondback Interval Carbon Flat Bar road bike showed up.

First off, lets start with that paint job. Wow. Between the amazing job they did on the Podium series and now this, we’d say that Diamondback’s graphics department is knocking it out of the park right now. With the subtle, nuanced paint job, pops of color, and thoughtfully designed graphics, this is a bike that will definitely turn heads out on the road. Or outside your garage. Or parked outside the coffee shop. Pretty much anywhere. And that frame isn’t all just pretty paint either. With the Interval Carbon, the true beauty lies in the details. The Interval Carbon is built around a high performance, full carbon frame with a nice, relaxed sloping geometry that’s easy on the shoulders and back, but is definitely stiff and responsive enough to have some get up and go if you’re so inclined. But take a look at the frame around the stem…see the top tube junction scoops down into the head tube? That’s a feature normally found on high-end time trial and aero road bikes to decrease the aerodynamic profile of the bike. And lets look at that fork, it looks shockingly like a time trial fork. With it’s narrow profile and a sculpted fairing that helps eliminate drag space with the down tube. But it also includes disc mounts. And fender braze-ons. The bike also has internal cable routing, and is compatible with both mechanical and electronic groupsets.

This is a bike that truly marries performance and comfort in the best possible way. Out of the box it’s equipped with a set of flat handlebars, Shimano Tiagra 10-speed trigger shifters and derailleurs and a set of hydraulic disc brakes. This gives you plenty of gearing and powerful stopping power to get around on any roads. Nice, big tire clearance lets you run some fairly large volume tires, and still gives you room for fenders. There is also a set of rack mounts in the back, if you’re the type that prefers to put your stuff on the bike instead of your back. The really intriguing thing to us though is how versatile this bike is. We took it out for a quick spin around the parking lot, and were really surprised at not only how fun it was ride, but also how responsive and lively it felt. This is a bike that responds to rider input, both in the pedals and the handlebars.

With a little bit of technical know-how, a rider could easily have multiple road bikes in the Diamondback Interval Carbon. Want to do a charity ride or just get out for some exercise on the weekend? Roll it out of the garage and you’ll have a comfortable bike that will go as fast as you want it to. Commuting or cruising around town? Throw a rack on it, some fenders and you have a super comfortable, practical bike for getting around. Doing a fast ride or even racing? Replace the flat bar and trigger shifters with some drop bars and Shimano STI levers, and you would have one sweet carbon fiber disc-brake road bike. If you’re looking for a bike that delivers the very best of all worlds, with unmatched performance, versatility, and flexibility, we would definitely recommend the Diamondback Interval Carbon flatbar road bike.

  1. So its been a little over a month since this was announced. I’ve not seen much on the web about the performance of the bike or any other followup reviews. Has anyone purchased this yet? I want to snag one of these as a budget commuter however the feedback is lacking.

    Where are the new owners of this steed?

  2. Very interested in this bike, but still can’t access a geometry chart. Also tried looking on the Diamondback website, but the Interval is not shown since it’s a Performance exclusive model.

    1. The weight for my Large size (20 inch frame) is 22 pounds, as weighed at the Performance Bike dealer in Boca Raton, Florida.

    1. Hi Nick,
      There’s definitely room for some weight savings on pretty much any bike, but it doesn’t have to be an big ticket item like a wheelset. A upgraded saddle, tires, seatpost, and other components can help shed a surprising amount of weight from any bike.

  4. Doug, I just bought one and have ridden it on gravel albeit on a very smooth gravel. I would suggest a knobby tire if you will only be riding on gravel roads. I met with the techs at my local bike shop and they showed me a tire that had knobs that were not that aggressive. I ride a combination of gravel and pavement with the stock 32mm tires. The bike rides and shifts smoothly. The bike weighs 24 lbs, medium frame, including the pedals and all the reflectors. You’ll need the weight for riding on mixed surfaces. I suppose you can lighten it up with new wheels, carbon bars, pedals etc. I have a road bike(17lbs) and it rolls faster than the Diamondback, however, I do not ride on gravel roads with that bike. You’ll have no problem riding your local mixed roadways with the Diamondback Interval Carbon. The geometry of the bike is very much like a mountain bike. You’ll ride in an upright position. The only other bike I considered in this class was the Specialized Sirrus Carbon. It costs at least $300 or more than the Diamondback carbon. However, I was unable to find it locally and bike shops that did have it would not ship due to arrangements with Specialized. My wife has the Specialized Sirrus Comp in an aluminum frame and it weighs 25 lbs. The carbon frame would be lighter but not that much.
