|Giant TCR sizing question||kinger|
Sep 20, 2002 2:44 PM
|This is for those of you that have a Giant TCR. Per their sizing guide I could fit into either a medium or large frame although it looks like I'd fit better in a medium. However, I would need a #4 (borderline between 3 and 4) seatpost and a #3 stem (longest). I have ridden a large frame and it does feel a bit big for me but haven't found a local shop with a medium bike I can try yet.
Question is, what would you suggest would be the better fit. At 6'1" and 173 lbs. I kind of fall in between the two sizes and could be fitted into either. What are others experiences with these frames?

|i'm also about 6'1 (183cm) and test rode a large with 115 stem. it was just about right. i had sat on a medium (not sure what stem length) and it felt too small. i guess i had slighly shorter legs and slightly longer torso so personally i'd prefer the longer effective top tube the large has to offer.
i currently ride a 57 top tube with 130mm stem and its just about right.
if you got the medium: 55.5 cm tt + 130mm stem = 68.5
large: 58.5 + 115mm stem = 70
if i were you i'd go for the large...i have a 34in inseam...but maybe you have longer legs and a shorter torso and don't need to be stretched out as far.
also, how tall in cm are you? it seems a lot of people i know claim they are like 6' or so when they are really an inch or so shorter. try measuring with your back to the wall and see your height in cm...also your inseam maybe...
good luck man...get the TCR Composite!

|I bought a TCR2 recently. I'm 5'11" with 31.5" inseam, 190lbs. The medium fit with #4 seatpost, but I don't know the stem length. It's whatever was on the original build, I didn't change it. The large was noticeably too large.
I second briko51 - get the TCR Composite if you can. Awesome bike.

|Forget the Giant seatpost. You get around the sizing issue on the post if you go with something else. The Giant carbon post is also pretty heavy, and are known to make noise from time to time. I've owned a couple of TCR's, and used a Thomson or Time post in each. It will run you abou the same price to put something else in there too.
Easier resale too if you don't need a special sized post for the potential buyer if this might ever matter to you.

|Are the Time and Thomson posts aero-posts like the Giant? I think that's a cool feature of the Giant one. And what part of the seat post makes this noise? I haven't noticed that with mine.|

|No, the Time and Thomson posts are not aero posts but instead of the standard variety. The aero post on the Giant has been shown to not do much, or even to possibly hurt aerodynamics in testing. Check out what John Cobb has to say on the subject at www.bicyclesports.com for more info on that. He has stated that the Giant bike is faster in the wind tunnel with a standard post when commenting on ONCE's time trial set-ups. The air is pretty 'dirty' with legs moving around, and air coming in where the post is anyway, and the benefit is minimal even on frames with larger cross sections that can recieve a benefit from such a foil shape.
Some of the posts I haven't heard complaints on. A few through my shop have creaked at the frame though. Annoying, but not much else.
I don't think the Giant is a bad post. If the one you have works, then great and I would just keep it. I do think that there are better posts for the investment though if someone were to be building a new bike up.

|I have two friends with TCR 2s, one '01 and one '02, and their seatposts sing to each other. it's bad. I, however, use a USE Alien ti. if I'm suffering any sort of aerodynamic penalty I haven't noticed. you'd be perfectly fine with, say, a Thomson (or whatever else peloton suggested). I wouldn't recommend you get a USE post (setup is a pain; consider when you're more advanced).
|Thx for the info...||fbg111|

|that's definitely worth knowing. The aero looks cool, and works for me, and I'm not good enough to be a weight weenie yet anyway. But one day I may consider replacing it for something lighter. Glad mine doesn't creak though, that would annoy the heck out of me.|

|Thanks for all the input guys.
So is the consensus that a large frame would be the best fit for someone who is 6'1" and has a 34" inseam? Anyone about that size have any additional input?

|I'm 6'3" with a 89.5cm inseam. My TCR Zero is a 2001 model in large. Seems to fit good with a 120mm stem and a USE carbon instead of the Giant aero post. Wanted more freedom so that's why I replaced the post. Nothing wrong with the Giant which was a #3 bye the way.|

|and am only 5'11". However, I ride a 57 top tube with a 130cm stem normally. Based on the giant medium tt of 55.5, I would need a very long stem.I'm not getting the Giant post, elected to go with something else myself.|| |
