If your measurements are accurate (are you 6' tall with a 30" inseam?), you'd either want to go for a custom frame or see if you can find a compact frame (you might be able to find a frame with a longer top tube but without a proportionally long seat tube). Just out of curiosity, how did you measure your inseam?

As for road or triathlon bike, well, that kinda depends on you. If you already have a road bike that is in working order and you plan to keep it, I'd say go for a tri bike. Cervelo is known to have somewhat proportionally longer top tubes compared to some other manufacturers.

Good morning Tibbs.

Thanks for helping me. I have checked again, and
yes, my inseam is 30". But my height is not 6'. It is less. I am 176cm. This is bordering 5'9 & 5'10.

I am thinking more in the Tri bike direction. I was only thinking in terms of road bike if a tri bike will not fit me, as I could not see any model that has the geometry that fits my proportions.

Thanks

Baruch

Searching for the bliss of ultimate exertion.

Ok, that will make a big difference. Ultimately, you should go and get a fitting done to determine the optimal seat tube angle, top tube length, seat tube length, et cetera. Short of that, I'd just look for the frame with the longest top tube you can find in your size. I'd assume you ride about a 54cm or 55cm road frame?

Yes, my current road bike is a Cannondale R900 and it is 54. I think that it fits me well. But when I looked at fit charts, it seems that I am suppose to have a longer top tube. I was trying to follow the slowman bike picker. I was not sure how to categorize my proportions. It seems that perhaps I have longer torso and short legs. Would you agree?

Yeah, it sounds like you have a longish torso and shortish legs (I'm somewhat the same, just a bit taller). The first question you need to answer is What position do you want to ride? Do you want a steep seat tube angle or a shallow seat tube angle?

FWIW, I'm 6' tall with a 34" inseam. I like a pretty compact cockpit, so I usually ride a 55.5cm top tube on a time trial bike. I don't like my seat tube angle to be very steep - right around 75 degrees. I'm able to generate much more power in this position. It also helps that it effectively gives me a little more top tube on a slightly smaller frame.

I have been training, racing and riding on a road bike. In the period before the race season, I normally install a profile carbon stryke bars. I don't find that I can stay in this position long enough. And when I climb, I find that I don't have where to hold as I prefer holding the base bars on really hard climbs. Since I will be doing a full ironman this summer, I decided that perhaps I should give a steep angle bike ago. But if I can’t be fitted I also considered the option of shorter clip-ons on my road bike setup. But ideally, I would like to go for a tri bike with a pursuit bar and bar-end shifters.

My LBS is more roadie oriented and I prefer to establish through your help which bikes I should shortlist. Then, I might travel further to a bike shop that fits for triathlon.

I would change up the order in which you plan to do this. I'd go to the bike shop that fits for triathlon first. Their fitting will help determine what bikes you should look at. Without knowing your fitting information, you might as well base your decision on looks alone for a frame choice.

Mr Spinach what is wrong with your Cervelo P3?

Something is wrong with the calculations.

I'm 5'9" an I thought my was 30". Maybe it is a touch more, but I think not.

Anyway, I fit nicely (in a proper slowtwitch fashion - right angles and such) on a 52ish cm top tube. I have a 56 cm road bike that I tried to ride as a tri-bike and I ended up needing a profile fast forward post and a 90cm stem to make it work (ie a 52cm tri-bike works well).

I'm not thinking your proportions are terribly unusual. As someone on another forum pointed out, I think many, many people buy frames there are too big and end up with forward angled seat posts, really short stems, riding the nose of the saddle, or are way too stretched out. All of those symptoms point to a frame that is too big. Easy fix, get a smaller frame.
