Is my bike too big?(8 posts)

Is my bike too big?azukor

I have a 2000 Giant TCR 2 in the large size. I'm 5'10" and about 150lbs. I'm only 18, and I'll probably grow between 2 and 4 inches more. But for now, I'm wondering if my bike is too big. I know I'm at the lower end of the spectrum for a large, but I have the smallest seatpost from Giant, and I'm getting a slightly shorter stem than what i have now (which is actually very long). The bottom line is, is this frame too big for me? Should I try to sell it and buy a medium, or will i be okay riding it? Does it defeat the purpose of compact sizing? Please let me know what you think. Thanks.

You don't mention WHAT SIZE the frame is (this is given in inches or cm), how long the cranks are, what your inseam or standover heights are, so I'm not even going to TRY to answer this one. A good rule of thumb is to have at least 1" standover space between your crotch and the top tube, while standing flat-footed.
If you think that you are going to grow 4 more inches at age 18, you're crazy.

unfortunately the OCR has a sloping top tube and only comes in small, medium, and large. so it's hard to say what's a medium. their rough guide is 50cm for medium.

your "rule of thumb" again is hard to do on a sloping top tube compact geo frame. i" higher than front of top tube or back near the seat?

i think the post-er would need to go to the bike shop to figure this one out. you may have shorter upper body and/or arms if you feel the frame makes you reach too much.

He did mention he had a LARGE TCR 2. Since there are only 3 sizes, it was very specific. 1" Standover on a compact frame design? Since when?
maybe if you read the post carefully, McNustyD'Ohhh!!!

you'd see in the first line that he has a LARGE. And if you knew anything about the OCR- which obviously you don't- you'd know that it's a sloping top tube frame (and comes in sizes small, medium, large), so standover height is irrelevant. Sizing by standover, for a level top tube bike, is like going back in time 20-25 years. But at least you got one thing right, he is crazy for thinking he will grow 4" more.

First of all, the large size is about a 55cm, but if you knew anything about the compact sizing concept, then you'd realize that the number size of the frame is irrelivent. I know the whole idea about an inch space when you stand over the bike, but sizing is completely different with a sloped top-tube and a compact frame. And by the way, your ignorant comment about my predicted growth is ill-founded. You know nothing about my genetics, or my families growth history. Maybe if you want to make a snide, sarcastic comment in the future you should do a little more research.

As everyone has pointed out, it is very hard to say. "Fit" includes so many factors; standover, reach/top tube length, stem length, crank length. But any LBS worth its salt should, if they sold you the bike, slap it on the trainer and help you determine what adjustments you can make for a proper fit and comfort. At your height, a large is probably a close call. How much seatpost shows above the frame (and below the saddle) when you are the seat the right height? Are you too stretched out riding in the drops or on the brake hoods? How does it FEEL? Too many factors for answering in this format. At 5'10" it is probably a close call.

Adam, a lot depends on your inseam length. I'm 5'10" with a 33.5" inseam, and when I was shopping for bikes the large Giant OCR fit me better than the medium. Had I gotten it, I would have needed to get a shorter stem. I wound up getting a 57cm Lemond Nevada City and swapping the 13cm stem out for an 11cm, and it fits me fine now. I doubt that your bike's really too large for you--you might not be able to get the 2" drop between saddle and bars that some racers like, but if you aren't going to race (or don't mind being comfortable), you're probably fine.
