Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

You decide.

What do you guys think?
The first question "why?" he explains on his site:

Laboratory testing and Finite Element Analysis proved that the RoundTail™
provides more than 10 times the vertical compliance of a standard double-diamond frame,
and the ring design absorbs 60 times more road vibrations.
This breakthrough reduces stress and fatigue to the rider's body, which means you can spend more time in the saddle - comfortably.
so now the question is: will the notoriously conservative riding culture give it a chance?
What do you think?

I looked at the website. I don't see any quantitative information / peer review related to the statistics of 10X, or 60X. I did see data related to a weight differential vs. diamond frames. The increase was 250 g. Most of the data was anecdotal.

Interesting. Not sure how much more comfortable it would be, but I'd be curious to see if it did indeed absorb more of the vibrations and thus make a days riding more pleasent.

I doubt that you convince many of comfort advantages, but I might buy one for novelty reasons.

Stress and fatigue comes from pedaling hard, not from road vibrations. More often than not marketing is about fixing problems that don't exist.

I might set one up as a gravel grinder or maybe a fixie. I can't see myself buying one as a main road bike or mountain bike.

I'd miss having a second water bottle mount. That alone would be a deal breaker for me for a road bike.

Not interested, not even a little. I don't want more vertical compliance.

Work in some urban coffee houses, tattoos, skinny jeans and bacon in the marketing and he'll do fine.

Too much of a departure to achieve a result that may not be required. The design sacrifices one water bottle position. The FD mount looks a bit fragile in the case of a chain mishap. RD cable routing a bit circuitous, but should be workable. What's the target market?

Tres Fredly -- Finally a bike that even the 'bent riders can make fun of.

I find the premise unconvincing. If you can't set up your road bike to feel comfortable on long rides, chances are that a race bike is the wrong choice for you. Besides, if you're riding so far, you'd think it would be nice to have a logical place to mount that second bottle.

If he can sell these, more power to him. But I won't be in the market.

Confused... why are the wheels mounted on tabs outside of the circle? wouldn't the effect be better if one used ellipse shaped stays, and mounted the wheels in the path of curve? I have more questions... who do I ask?

I personally dont think they will sell as they look ridiculous and there are plenty of company's out there that have done some great things with the seat stays like specialized with "zerts" and they dont look so funny. but thats just my .02

Thumbs up for the design and the idea ... but ... doesn't that look like a very complicated, unaero and heavy way to "absorb road vibrations"?
If you want to absorb vibrations, you can get tubular tires or just wider tires or full carbon rims or a softer saddle or even something like a suspension seatpost (cobl gobl-r ?), which would give you about the same effect, but in a handier package.

You're missing the point -- you're supposed to add your balloon tires, full carbon rims, softer saddle, and suspension seatpost to the cushy frame. Don't forget to wear your gel shorts...

You don't need weird design to have a comfortable ride, you just need a steel frame.

Nope, not a chance in hell will this be anything more than an oddball curiosity and an exceedingly ugly one at that.

I did a social ride about a month ago and saw 3 or 4 riders with those bikes. Each one claimed it's the best bike they ever ridden. One guy offered test rides to anyone, but the frame was too small for me. Apparently it does make the ride smoother...

Sorry, too stupid looking for me, even if feels like you're riding on a cloud I wouldn't buy one. And what happens when you need to lower the seat post? then you have an even stupider look with the bottom of the post sticking down into the "circle"

While this appears to be solution looking for a problem, I wish him the best of luck.

It's a marketing gimmick, not engineering.

Marketing gimmick, plain and simple.

It's also a gimmick that, as mentioned, compromises some very real, non-marketing, utilities of the diamond frame.

Fail.

If it doesn't compromise performance it will appeal to a niche market. I predict it will be a cafe cruiser.

Encourage your friend to save the time and effort and most of all money. This is something that is destined to fail.
