They improved the base of the unit - it's much more stable, works better, and is more realistic.

A good write-up of the differences here:http://www.dcrainmaker.com/2013/08/kinetic-updated-trainers.html

The main differences that I see are that this model has adjustable roller pads for your feet and the optional (sold separately) preacer curl and leg extension attachments. it also has a better seat adjustment IMHO.

Brian, I have no idea if there is any difference, as I have only experience with the "other" model. I just really like the one I bought from Amazon.

The Magnetic Trainer is better suited for more resistance...... Mountain Bikes.The Fluid Trainer is more suited for Road Bikes..............gives a authentic road feel

I searched for the asin , I could not find it , But ...KK traineras that are priced at 329 are the Kinetic Road machine Fluid trainers , it has the same frame, same color, but a different resistance unit, so its really not the same.

I don't believe there is a difference at all. They appear to be the same and the dimensions are the same. Sometimes a product doesn't get removed or updated when there is a change, so it's probably the same one at the "original" price. This is a great stroller, especially if you have multiple smaller dogs that like to ride together but it really is only usable on a good surface. It doesn't turn so well on dirt roads and such and doesn't get much traction.

It's just the updated model. The red one is newer. No difference though as long as it says that it will read and clear ABS and SRS codes.

The first model is not listed on Google search. The second one may be this specific product. Since I could not find the first one, I can't make a comparison. Sorry.

I don't know the difference but must admit that I am happier with this one more than the previous one, it seems lighter and more durable. Sorry can't be more of help

When I ordered the T-2300 Kinetic rock and roll trainer,the T-740 Skewer was included with the unit.I would recommend using the skewer when you use the bike trainer because it fits very well in the 2 cone cups that secure the rear wheel.

First time I have used this so I couldn't tell you what the difference is. Sorry.

This is the first one I purchased, so I am not sure the difference. I would think it has added enhancements. Check out the Withings site for more details.

Mike, there's nothing different about them, in fact they are the same. RTR simply means Ready To Race. Your purchasing a complete kit with everything you need in the box.

I looked at the cheaper version and I don't see much difference except for the body model itself. This wasn't available when I bought the expensive one. Go for it. Can't go wrong. They both teach the same concept. Enjoy--the product is fun and very realistic!!

They are fundamentally the same, but R stands for retail. It has a few less features and a shorter warranty. Go for the version without the "R and you will get a 5 year warranty and some more useful control features. I bought 2 of this one, but Amazon has it direct for a little less, but they charge tax in CA. http://www.amazon.com/gp/aag/main/ref=olp_merch_name_9?ie=UTF8&asin;=B00G4CIG7M&isAmazonFulfilled;=1&seller;=A2CHZ585KZGNN0
