First of all, I've learned my lesson: don't cheap out and gamble on a bike that doesn't fit. Yeah, I f***ed up.

I've owned a Cube Agree that I bought online six months ago. I'm 6' tall with slightly longer-than-average legs (35"-36" inseam). I thought I'd be fine with a nominally 58cm frame (that's Cube's number). But I've finally come to the conclusion I was wrong. I have to max out the seatpost in order for my legs to feel "right," but that throws everything else awry, fit-wise. For example, I'm much more likely to get numb hands, being all hunched over (yet straining a bit to reach the hoods/drops). I actually prefer a more aggressive setup, but my current fit is one step past "aggressive," and is just not comfortable for a typical hour-plus ride. The height of the saddle is about 25 cm (10 inches) over the height of the stem. Yeah.

It's frustrating because I really like the bike's ride quality. It feels really stable in bendy descents. It's stiff and it's light and it's comfortable over rough roads. It's a very good carbon fiber bike.

So, I'm wondering what sort of options I have that won't be too ruinous. I suppose I could try to get something on a trade-in at a LBS, but since the bike is used and not very common in the U.S., it might not be considered very desirable. In addition, it has a small scratch on the chainstay I'd be obligated to point out. I could buy a new carbon frame online (or aluminum or steel--I'm not religious about it), but I'd be back at square one on fit--I wouldn't be confident in the fit unless I purchased a frame at a LBS. Maybe sell the bike and start over with a new or used locally-purchased bike? I dunno, but I don't want to spend > $1000. Should I just live with my error (it's been "almost" good enough for six months)? What do y'all think?

Possibly get a new fork with a longer steerer? (I assume the one on the Cube is cut short) and add lots of spacers? Invert the stem for higher bars? Buy a Chinese carbon frame, or any other frame, and swap parts?

Some bikes show their geometry online, so you could buy online and get one that fits. I question what "58 cm" means to Cube---at 6' 0" 58 cm should be fine height-wise---I'd wonder if the frame is mismarked. Have you contacted Cube about it?

I have to imagine you have ridden before--does the Cube's head tube look a lot shorter proportionally than you are used to? If the top tube sloped down I could easily see 10 inches of seat post exposed, but most 58 cm frames the top of the headset would be just a few inches down from that saddle height with a sloping top tube.

As for options, nothing good, I am sorry to say, at least that I can imagine. You are going to have to buy a frame at least (or maybe just a fork, but still not cheap.)

You could find someone with a 60cm bike with taller (H2) headtube and trade..

I might know a guy...

Pictures please.

Timtak it.

He needs higher bars.

Reverse-tak it?

Katmit it.

RollCNY was just saying the other day how a 58 allows him to accommodate his very long legs and arms at a height similar to yours. Are your arms short? You can get sbout an inch rise out if flipping your stem with a 7 deg stem, much more with a 17 deg stem.

nice.

I can't visualize a 10" saddle to bar drop on this frame...

This one has a lot of post showing, stem pointed down and a reasonable spacer stack.

There may be a 4 inch drop.

I find it difficult to believe that at 6' a 58cm bike can't be made to fit you.

Has the steerer tube been cut? You can raise the stem 4cm with spacers below the stem, if you or someone else hasn't already cut the steerer.

You can raise the bars a number of centimeters by flipping the stem up, and going to a steeper angled stem.

So as stated above pics would be helpful.

My bet is using the allowable amount of spacers, and a stem with the right rise, that frame can easily be made to fit you.

FWIW, I'm 6'1" and have bikes that all fit me, with top tubes from 56cm to 57.5cm, which are al smaller than your bike.

You could rotate the bars until they're upside down.

Damn! Tough crowd!

Here's how it looked when I got it. I raised the saddle a bit more than what you see in the photo. Maybe I exaggerated when I said 10 inches.

The steerer tube has been cut. Obviously I've enjoyed this bike--mostly--for months, so it's not WAAAAY off. But it could fit better. I had lowered the saddle a cm or two a few weeks ago and soon suffered knee pain, which I've never had before. So back up went the saddle/post.

Get a +17 degree stem and try that first.

Hard to tell from the pic but it sure looks like you have a seven-degree stem angled down, which you could flip or better still replace with a seventeen-degree stem. That might do it for you. Hard to see where that can be a 58cm frame though ... I wonder if it is mislabeled. My legs are about as long as your and I rode a friend's 58 cm Cannondale Super Six and didn't have nearly that much seatpost showing.

Zackly.

Do you ride on your tippy toes?

That doesn't look like a 58 to me. Maybe take some measurements and confirm with Cube's geometry?

I was skeptical too, but it says 58 cm underneath the down tube, and it's why I said, "nominally 58cm frame (that's Cube's number)" because I was not totally convinced it was right in the first place. I've always figured that the 58 cm figure was because of a non-standard frame geometry, i.e., it's "equivalent" to a standard 58 cm frame. Sheesh. Seems plain wrong, doesn't it?

I ride with my feet pretty much parallel to the ground, certainly not tippy-toes.

Anyhow, merely flipping the stem might be all I need--or failing that, getting a 17-degree stem? You guys just made my day!

It could be useful to assign blame for cutting the steerer tube too short. What mean is, if it was the fault of the store, perhaps a discounted replacement could be obtained. No other reason than that.

Don't forget when you flip the stem, the reach gets shorter, about a half cm. That may be good here.

The steerer tube looks like a reasonable length to me, especially if it is carbon. I'm not sure if the OP has actually had a fit

How about getting a seatpost with 25mm setback?

You don't use setback to adjust reach of the legs to the pedals or hands to the bars. Only to adjust horizontal knee position relative to the pedals.

Usually as much as 40 mm of spacers is safe. Can you see if there is that much in the photo. I can't.

Its at least as tall as the stem which are usually ~35-40mm tall.
