Product Description

"Road feel" is what just about every indoor trainer chases in some fashion. It makes sense, as most of us prefer riding outside. Most companies use a weighted flywheel along with some kind of magnetic or fluid resistance to give you that elusive feeling. A few use a computer program to create the magnetic resistance. Only Kinetic by Kurt employs a resistance unit and frame designed to mimic the natural movement of riding out on the open road. They put both parts together in the Rock and Roll Trainer.Kinetic answers the resistance issue with their Road Resistance Unit. The roller itself is the first part of the solution. It's made of stainless steel and is 2.5in (6.35cm) in diameter, which is a good bit larger than much of the competition. The larger roller means less wear on your tire and it reduces the temperature of the spinning elements. The right side has a 6.25-pound (2.84kg) flywheel, the heaviest around, which is what gives the feeling of momentum when you're spinning up to speed, holding speed, and slowing down. On the left side is a unique two-part resistance unit, which is the heart of their system.The resistance unit is unique as it's made of two parts. The first is the driver made of a small flywheel embedded with six rare-earth magnets. The other half is a completely sealed cast-aluminum fluid chamber that is bolted to the housing containing the driver. The fluid chamber contains an impeller with corresponding magnets. As you ride, the magnets in the driver spin the impeller through medical-grade silicone fluid to provide the resistance. And since there is no drive shaft entering the fluid chamber, the Kinetic design eliminates a common design weakness of most fluid-resistance units.Of course, the system builds heat; your energy has to go somewhere (in this case friction). However, the fluid acts as a coolant and the chamber has 80 cooling fins on the outside that act like radiator fins.

I've been riding the Rock & Roll for several months now to supplement my road riding. I was a little hesitant about the rocking feature initially. As it turns out, the default stiffness setting doesn't move nearly as much as I was expecting. Of course, you can loosen the resistance for more motion, or really tighten it down for even less.

My main concern was longevity of my bike frame and I feel like having a little bit of give in the trainer will help prevent damage. I'm not small at 200lbs so a little give is a good thing.

The resistance unit itself is smooth and operates with a relatively little noise. Our house is very open and I ride directly below our bedroom. My wife has never been awakened by the trainer.

I chose to purchase the model with the additional flywheel. I use it when I'm doing consistent pace riding. If I want to do intervals I almost have to remove it to prevent tire slippage. Not a problem, since most people would prefer less flywheel effect for intervals anyway.

This is a quality tool that will definitely help you pack on the training miles. The rock & roll feature is not crucial, but is a worthwhile feature if you have the extra money to spend.

Ill start off by saying I am a beginner biker. I have ridden maybe 40 miles in the last two weeks and decided to get this trainer for rainy days because I can't stand the treadmill. I have tried out a standard stationary trainer at a local shop and it was very stiff but still good. I got this yesterday, set it up.. which was very easy.. and was able to ride it with no issues. I don't have any major noticeable bouncing or too much wobbling if you are riding correctly. It feels so smooth and fairly lifelike. My legs were burning pretty bad quickly riding it but I'm not sure if it was from working out or the difference from biking on the road vs a trainer. I have the stationary riser block but i think I'm going to return it and get the one that moves, i believe it will feel more natural with the light movement you get from this trainer.

the bad: We tried to put this on our carpet.. tired rubbed a black spot into it. bummer. Then i put it on the linoleum and after riding about 15 mins this morning i found another black spot, but smaller. grrr. Im kind of annoyed. I emailed kurt kinetic for suggestions. I can't imagine the mat will help because it is foam and it would only take away a couple millimeters of clearance.. plus i don't care to spend 60 on it. I might put down some contact paper with duct tape to cover the spot directly under the tire. It may have happened when i was riding standing up but still..they advertise this.

update: i got a very quick response from kurt kinetic- they suggested to tighten the rear bolt and loosen the inside one. It raised it a touch and should alleviate the problem. This company seems really great.

update 2: its still sagging a little..

I'm a fairly recent convert to using an indoor trainer. As much as I prefer riding outdoors, I have two small children and live in Phoenix. Thus, as summer hits, it's too hot to go riding in the middle of the day, yet with the kids I can rarely get out in the mornings or evenings.

I previously used a basic fluid trainer but wasn't ever really happy with it. Sure, it was under $200, but it didn't coast at all, was a little too noisy, and didn't "feel" that great. Standing up, for example, wasn't an option.

The Rock and Roll has a wonderful near-road feel and the movement does make a difference. You don't feel like you're going to topple over at all but that extra up and down and side to side does help you know when your form is slipping and makes the ride a lot more comfortable. The flywheel is awesome, letting you coast but also forcing you to change resistance to keep a steady pace (and avoid knocking because you're in too high a gear).

Lastly, I use this with TrainerRoad.com to measure power output and do structured workouts. Combine that with some Netflix in the background hooked up to my flat screen and it keeps my attention for at least my 60-90 minute indoor rides. I don't have a power meter, but TrainerRoad and the Kurt Kinectic are well-calibrated to get me in the ballpark and allow me to do power-based workouts for (at least) my indoor rides. Since my outdoor rides are all with a group where I don't control the pace, this really lets me tune things on the indoor days (which are 70% of my summer workouts).

In summary- if you can afford it and have the space, the Rock and Roll is worth it. If you can't, at least go with Kurt since the flywheel resistance unit is the best feeling I've found.

I want to start by saying that I am a runner more than a biker, but I have been using this trainer during recovery from an injury. Serious bike riders may have a different opinion. I have a couple of minor complaints, but overall this is a very nice product. I have been using it for a couple of months, I have maybe 400 miles on it and it has performed perfectly. So it seems well made.

The good:
- Setup was pretty simple all of the parts went together without issue.
- I like being able to use my own bike for indoors so its more like riding outdoors.
- The fluid unit provides consistent resistance. I like being able to adjust the load by just changing gears. So far it has not shown any signs of leakage or other issues. I have a real wheel sensor speedometer on my bike so I can easily judge how hard I am working and whether I am improving or not by the rear wheel speed. I am comfortable with the load in a middle gear, so have some room to add or remove load.
- I have the standard flywheel on it, I didn't bother with the heavier one, acceleration/deceleration is pretty smooth if you get the tension on the rear wheel adjusted correctly.
- The bicycle attachment make bike attachment/detachment quick and easy and the bike seems secure in it. I can switch between mine and my wife's bike with a lever throw and a tension adjustment.

The bad:
- The trainer says it fits any wheel size which is not completely true. When I attach the bike, the rear wheel is just off the groundm so technically it does fit. But when I get on, it just barely drags on the mat because the springy mount sags slightly. I weigh 170, a lighter rider would probably not have a problem, a heavier rider would not be able to use it.
