6' + TCR riders, I need your advice!(12 posts)

6' + TCR riders, I need your advice!StupidLight
Mar 11, 2003 5:24 PM
I am looking into a TCR composite frame, and was hoping to get some feedback on sizing.
I hit the Giant website, made some measurements, and discovered that on the basis of my inseam (or Giant's BB to rail measurement), I could fit a medium or a large frame, but on the basis of my reach (seat post to bar), I would need a large frame with about a 110mm stem.

I was wondering:
1) what size TCR frames other riders about my size were riding?
2) what length posts/stems they were running? (The secondary question here is whether to go for a 270mm or 350mm post -- I'm not a big fan of aero posts, so I'll probably go Easton or USE)

I am 6'2", have a 35" (89cm) inseam, and relatively long arms (34/5 shirt size). I am currently on a 59cm traditional steel frame with a 57.25cm top tube and a 120mm stem and am happy with my fit, but am also an avid mountain biker, and thus am not "afraid" of compact geometries that show some post. That said, I _really_ don't want to run a stem longer than 130mm because I don't like the effect this has on steering.

On the basis of the Giant site, I'd choose a Large. What do y'all think?

I ride a large TCR. I'm only 5'11" but I also have a 35" inseam and 34 arms - obviously I have a short torso. I use a 110 stem and the bike fits me like a glove, so you're probably right that you may need a longer stem. But I think you'll find the size comfortable.
6' + TCR riders and compact geometry?dtufts

I'm 6'4", 36" inseam and 36" shirt sleave. I'm looking for a new ride and the LBSs (that sell giant) tell me that I need the new XL. But some of the LBSs have told me to avoid the compact geometry because of my size. Have any of you 6'+ guys had any trouble with the compact geometry, or is this just bs from the non-Giant dealers?
Total (L)BS! (Less is more!)StupidLight

Ever been on a mountain bike? If it was made in the last 15 years, then you were riding on a "compact geometry" bike.
Compact frames can be built as beefy or whimpy as the manufacturer pleases. There may be a difference in how the bike feels and handles vis-a-vis a conventional frame, but this has nothing to do with your size and everything to do with the material and geometry chosen for the frame.
If you're a real big guy, get a nice stiff post like a Thompson to help keep things solid. Modern seatpost design has progressed to the point where you don't need to worry about how much post you have showing (I mean if a Thompson can survive MTB downhills, surely it can deal with the occasional pothole).

These giants have a _very_ generous effective top tube, so there's plenty of bike for you here.
In fact, I threaded this topic because at 6'2" I was afraid I might be a bit _small_ for the large frame.
Giant doesn't have the sizing tables for the XL up yet, but go to:
and check out their sizing recs. for the other frames.

I am 5'11" with a 32 inch inseam and average arm length......I ride with a 120 stem. My seat height ground to top of seat is 99cm and my bar height is 90cm......look at my earlier post on " Worthless info: My rides" and you will see the bike from a side angle. I know you said you do not like aero seat posts, but I tried the deda Black Stick and there was a lot of flex at the it was right at the maximum line. Might want to go with the Easton post since you are bigger.

Saw your thread earlier. That's quite a formidable bevy of bikes you've got there. Hats off!

Given the amount of post you have showing, your stem length, and the spacers in the stack, am I right in assuming your frame is a Medium?

As for seatposts, I'm an MTB-marathon rider who's been riding flexy ti and carbon posts on hardtails for over a decade for comfort reasons, so I'm probably a lot more tolerant of post flex than most.
I assume the Deda you had maxed out was in the 200-300mm range? On the Large frame, Giant says I need their 270 post, but I'm considering getting a standard 330-350 MTB-length post (EC-70, EC-90, or USE Alien Carbon) so I don't have to worry about max extension issues, and I can migrate the post to another bike if I decide that carbon on carbon is overkill.
What do you think?

Agree...........I could ride the large for standover and handlebar stack, but the reach would be too long......the large has an effective top tube of 58.5 my medium 55.5.....all my other bikes have a 56-56.5 top tube, that is why I went medium.
yup, large nmgtx

I am 6-0 and ride a medium frame. At your size, I would definitely go large. When I bought mine I got the wrong seatpost shipped, and had to return it to get the right size, and during the wait I put an Easton carbon post in. When I got the right size (a week's wait) I found the Easton was actually quite a bit lighter than the Giant post, and I liked the ride better anyway. The Giant post is collecting dust on a shelf.

I'm 6'3" and ride a large with a 120mm stem. I also opted not to do the aero post and am using a carbon fiber 350mm Easton post. My conventional Trek is a 60 cm and the TCR actually has me stretched out a bit further since the top tube is about .25" longer. A large should fit you just fine. The best thing to do would be to find one at your LBS and take a test ride.

6'.75" 87cm inseam. Just bought a Large tcr comp 1. I had to switch the seatpost out because it put me too far back behind the bb, due to what I expect are relitively short femurs. compensating this way gave me a 100 or 110 mm stem (can't decide which yet might try and find a 105). I would definitely go for the large.
Thanks! One last thing: BB length for DA double?StupidLight

Looks like the Larges have it!
One last question:
What length spindle should I run, if I'm going to set this bike up with a Dura Ace double?
