sloping top tubes - is there any hope?(29 posts)

sloping top tubes - is there any hope?stan_b
May 8, 2003 8:47 AM
As soon as I saw them coming out, I hated the look of them. To be fair, I have never ridden one and I have no desire to. I'm noticing with the 2003 models more and more are going this way. Are we to assume that soon all road bikes will be like this? Have most here just gone along with the change?

I bought a 2002 Jamis Eclipse last fall which I hope will last for many years with a straight top tube. Part of the reason I bought it (I already own a Specialized) is fear that if I didn't buy it now, soon the model would change to the sloping top tube.

I know I can't be the only one who doesn't like the sloping top tubes.

Is it possible to care TOO MUCH about a thing?cory

My Atlantis has a sloping TT, and I never even noticed until somebody pointed it out to me. Jeez, they're just bikes...would we even WANT them all to look the same?

Blasphemy. There is no such thing as "just bikes." That's it, you're voted off the island.

Well, at least if you could not tell it was sloping, then it couldn't have been that bad. :-)

They slope the top tube to get the bars higher, there's a method to their madness.
That slopes up, good. Not sloping down. nmSpunout

You can use a taller head tube and not have the top tube join at the top of it, so you don't really need a sloping tt to get the handlebars up. I've seen lots of bikes with extended head tubes.

I'm shocked; however, I do recognize the usefulness of the design in some applications.

That bike is a Riv All Rounder, which is based on Bridgestone MTB geometry and has 26" wheels. That is about as far from a true road bike as you can get and still put drops on it. Now while those are ridden on the road, they do not really count as an example of a Riv roadbike. If you look at the "non-all rounder" models at the site, I think you will find them to have no sloping top tubes.

Just wanted to chime in on this before Doug joins a monastery or something.

Most Riv road bikes slope UP from the seat tube to help get the bars up (this in combination with a headtube extension and lots 'o spacers if you want 'em WAAAAAY up). It's usually just one or two degrees, so not real obvious, but its there. I have a Riv road bike and can't see it no matter how hard I look - and a Rambouillet where its sort of obvious.

Being somewhat new to road biking. What are the Pros and Cons of the sloping top tube/Compact geometry?

My bike does have a level top tube but more because this was the bike that fit and was comfortable.
There are some...are they worth it? maybe?sievers11

It makes the frame stiffer for mainly climbing, it also make the bike slightly more effecent because of the stiffer frame. It is also possible to make a lighter bike. All of these things said very few compaines do it right. The main down side is a flexy saddle contact with the bike(this could be a plus for some people) and sizing problems.

The advantages of a sloping geometry should not be sacraficed for a proper fitting frame. Your seat angle should be correct for you putting the saddle in right relationship to your crank, the length of the frame should be correct to give you control of a proper lenght stem and body possition. The head tube should be in correct relation to also put your body in a comfortable and effecent possition.

The biggest grip I have is that companies use the sloping geometry as an excuse to only cary a S, M and L frame. Hey executives good job cutting expenses, bad job getting me a bike that fits. Look at Orbea and Bianchi they are doing it right in their racing frames. They have a full range of sizes and so you can take advanage of sloping geometry, by getting one that fits.

(note: it pisses me off that bianchi's have almost abandoned standard geometry in their classic steel frames...classic steel and sloping don't go together)
Nobody knows. Oh wait, only 4 sizes are available. nmSpunout

Why do you care?alansutton
May 8, 2003 9:05 AM
Admire your own bike and be happy. Let everyone else do the same. We ride what we think fits best. For me, I ride a 46cm frame and sloping fits best. I can care less how it looks.
Missed the pointstan_b
May 8, 2003 9:41 AM
Yes I do admire my bike. However if the current trend continues, in a few years when I want a new bike, they will ALL have sloping top tubes. You like yours - that's great. I don't.
Buy a bunch then.alansutton
May 8, 2003 10:25 AM
Why don't you go out and buy a whole bunch of non-slopping frames. Create a demand and they will still be produced. There will NEVER be a time when all you can get is slopping frames.

you'd like to give me? What a stupid comment.

Frankly I like the look of a sloping top tube. The only question/problem I would have is if the bars couldn't be raised "high enough" or if the added seatpost length caused problems.
As long as you keep the dream alive, there is hope.sievers11

I don't thing this sloping top tube thing will last. I guess I could really care less for my racing bike. Stiffer and lighter sure sounds good to me. It also makes good sense for our junior team around here because they can make frame last longer as many of them are hand-me-downs and fit everybody.


for my touring bike, no slope please. I really wanted a bianchi eros as a touring bike, classic italy stuff...cromoly everywhere, all italian and no carbon. and no "virtual" top tube geometry. Touring is all about style and can't have any class riding 100 miles on rolling hills in spring, conversing about Copi on a Giant TCR. It is like discussing the symphony at the polo green with DJ Jazzy Jeff. If you are going to read Moby Dick, you need a musty old den, low light and a big old leather chair.

Do I still want a new bianchi eros...NO! Have you seen them now. Carbon fork, sloping steel frame, 1.25 threadless. What's the deal with that. And why on earth would you get a bianchi if it wasn't and white fade? Ahhhhhhhhhh! Wake me up from this nightmare.

I don't care for them at all. I'm tall, long legs, short torso, and ride relatively small conventional frames to get the shorter top tube, and have a lot of seat post showing with a rise stem. Can't help thinking that I'd look absolutely ridiculous on a compact frame with spacers/rise and a ton of seat post.

However, some mfrs make frames that don't slope so much. I looked at a Web ad for discounted Fondriest Madonna di Campiglio (looks attractive), and in the XL size (what I'd take), the slope is pretty mild, and the total seat tube length (bb to top of collar) is 59.5cm, which wouldn't expose extreme amts of seat post. I could probably ride that kind of frame, but will always look to traditional geo first.
Not to worryMel Erickson

There'll always be manufacturers making traditional diamond frames. Be sure to stash this thread away and pull it out in 10 years. I'm either a prophet or a fool, only time will tell.

the TT on my TCR lines up perfectly with my knees. It may be because I ride a large and the slope on the large is less exagerated.
I know, it makes no senseNigeyy
May 8, 2003 12:58 PM
I know I shouldn't care either.... but I do. I've never liked them either.

I just can't see myself on one -I also have no desire to have one. I don't know if it's because I associate a sloping top tube with a women's specific frame design (no disrespect to women, but for example, I don't want to wear a skirt -of course that doesn't mean there's anything wrong with skirts as a piece of attire) or whether I associate a sloping top tube with more of an MTB look. I don't know, [mumbling and gumbling] it just don't seem right.

It does seem to be the way forward though -more and more bike manufacturers are doing it. I agree with some other posters though; horizontal top tube frames will always be out there.

Anyway, sign me off as techno retro-grump Andy Rooney wannabe.
