im gettting a 2004 TCR composite 0 but i am not sure whether i should get the medium or a large fraam. im 5'11, short torso and relatively long upper body. i've heard about people around 6 had trouble fitting on a giant: medium's bit small and large is too stretch out? whats your take on this?

Yeah, I'm 5' 11" and felt that I would be between sizes on that bike. To be sure, why not go to the LBS and test ride a cheaper TCR in each size?

Probably get a medium, I'm 5'10 and feel great on it. My proportions though are pretty even.

HOWEVER, ensure you get the right seat post. This is the major downfall of Giant's aeroseat posts (or any aero for that matter). They are only adjustable for about an inch in total travel. So, if you get a size 1 for example you would not be able to raise the post high enough. Sadly, Giant ships with only a single sized post (size 3 I believe is normal) and enless you use that post size you will either have to swap it out with a normal post, try another aeropost which you LBS might agree to, or order a new one and hope it works.

As I said, I'm 5'10 and am using a size 1 post. This is on the min insert depth and is about right. Ideally, I would require a size 2, but I couldn't be worth the hassle of that. So, you should be good with a size 3 or 4, but of course ensure you try it out and watch how the seat is adjusted on eash bike this is by far the biggest anoyance with the TCR series.

I never tried a large bike, but I have seen it and I would not for a moment even consider that bike, it would be way to large. I don't know how much of a difference that 1" will make (I've never been 5'11) but you may also find the bike to fit too large. As a note, a friend of mine is 6'2 - 6'3 and the large fits him well.

Hope some of this helps, enjoy the bike

The 2004 TCR complete bikes are shipping with Giant's _amazing_ 180g 350mm _round_ seatposts.

Take a gander:

Post length is no longer an issue!

Good riddance to those gimmicky cricket bats!

Excellent, it was a complete pain for me. I spent two months trying to get the right size until I finally said screw it, mine is working. Although, even after all that I'm sure I will eventually get another down the road so I can raise it that tad that I would prefer.

Thanks for the info
Do you have a bike now to compare?hrv

Top tube length on the TCR large: 58.5 cm, med: 55.5cm,
quite a difference. I'm 5'11, and thinking about the tcr 0 also, probably a medium. My current bike is 56.5 tt and I think I'm too stretched out, no way am I going to a 58.5. Of course, stem choice can solve these types of issues too...

Also, I'm confused: what does 'short torso, long upper body' mean?

Long torso, short upper body?!? (You need a medium in any case)BergMann

Unless you have the world's longest arms, you will definitely need a medium.

I am 6'1" and have 34-5 sleeve and 35" inseam, and given the fact that the TCR is a compact geometry, the Large fits me "snug".

I'm using a 110 mm stem and a short-setback (1.5 cm)Giant carbon post which still has me mounting my carbon Aliante saddle on the last 5mm of the protected section of the rails. I also only have about 7" of post exposed, which isn't much for a compact design.

Don't be nervous about getting a 350 mm post, a couple of spacers, and a "flippable" stem (like the new Newton) for more rise at the front end.
This is a compact frame that is meant to fit more like an MTB than an old-school Italian road frame.

Test riding any TCR you can get your hands on is an excellent idea though, as the geometries are identical.

I'm 6' and was too cramped on my medium TCR2, I ended up selling it and am now building up a large. I also noticed that Giant is fitting round seat posts to the 2004 bikes except for the TCR Aero.

I own a 2003 Giant TCR (ONCE) I was also concerned about the bike size. I am 5"11 and test rode both the large and medium, the Large was to big for me, too stretched out.My ideal fram size is 56. The medium fits great. I have a normal size seatpost (250) and it's only halfway out of the frame. Great bike (if the 2004 comes with the same saddle as 2003, least comfortable saddle in the SI range- swap it)

I am 5'11" with 33.25" inseam and did a parking lot ride on medium TCR last night. It felt pretty good. My current bike has a 55cm top tube which compares pretty close to the virtual top tube that Giant offers. Nice bike for the money!

I could see getting the large if you are flexible and wouldn't mind swapping stems for a shorter length but the Medium with stock stem felt pretty nice to me!

I tested a large for 2 days before getting a medium with the #4 seat post. I was too stretched on the large but the medium felt good. I'm 5'11" 34.25" inseam.

To me it seemed like I would fit a bit better on the Medium, but with that short (97.something) wheelbase I kind of figured it would be sketchy as hell on high speed descents.

Hey Steve, where are you thinking of buying? I'm conidering the TCR Zero for a mid summer purchase (when I approach 15,000 miles on that aluminum litespeed).

Did you test ride at J.S.'s or Performance?
Dec 3, 2003 3:11 PM
I was at Performance in Northbrook last night and took one out for a spin... Both Northbrook and Halsted locations have a built up TCR 2's for $1999... (Same frame different components). I haven't seen any TCR Zeros on the floor yet...

It felt VERY light and fast compared to the bikes I've been riding the last few years... I also talked to another shop (Get A Grip) that told me that Gunnar is running a December promo where you can get the Waterford paint upgrade (more colors, more layers, more clearcoat) for FREE. Not sure if your into steel bikes but a Gunnar Roadie for $700 with nice components sounds pretty tempting to me!

what's the "retail" price on the TCR 0? nmK-Man

The obvious answer is to compare the frame dimensions with a conventional frame that fits properly and pick the one that avoids a goofy looking setup (many steering tube spacers, high rise stem, or stem too long or short).

If you've never been fit for a bike, get a professional fitting. You didn't enough information for any of the suggestions that were posted to be credible.
They need a Medium-Largefracisco

I test rode the Medium and the Large last year, and I felt in between both of them. Giant could really use a Medium-Large, although that would defeat the purpose of only having a few frame sizes.

I'm 6'1", with a 34" inseam.

I'm 5'8 and own a medium size, so I would recommend a person of 6'1 to go with the large size.
I must be the only person who actually likes the aero seat post. Mine has half an inch of extension and looks sweet.
