Giant Sizing help?

Question

Hi,
I am getting completely confused with the sizing of the Giant bikes. I was measured up at a bike shop and I was told that I was a medium or medium-large for the 2007 Giant TCR C2 that is apparently 50-53.5 cm. However I have seen a 2006 Giant TCR 1 which is saying it is 55.5 which is apparenltmly medium. The guy 6 foot tall.

I am confused!

I am apparently around 179 cm tall.

Anyone got any suggestions as to what size bike I need?

Answer 1

Large , med., 18", cm, bike sizes are just to get you close the first time. You need to sit on the bike and get fitted to the bike. The way each person is built will make the final determination on which frame size you will eventually be riding. The not all people 6' will ride a certain size bike. How you are proportioned will make that decision. If you have short legs and a long torso you will fit a different frame size that one who has long legs and a short torso, or have parts changed for a better fit. Ride the bike see how it feels and don't worry too much on frame.

Giant Tcr Sizing

Answer 3

I am 5'10". I ride a 19" Giant, although I could manage a Scott 18". The frame size is only the start, since you must also take into account the cockpit length. A bike shop that I went to said that an 18" Scott frame would suite my friend, who was 6'4".

Overall, I would look at a medium. You won't know until you sit on it and take it for a ride, so try a demo day, or rending.

Luck

Answer 4

I ride a Giant TCR C1 2005.
It is 55.5 which according to the specs is a large.
I am 180cm (5'11") and not terribly flexible and I have no trouble with set up.
That said I reckon you are better to go slightly smaller if you have doubts. You can always get a slightly longer headstem and pop the seatpost up a little. Comfort is everything. Especially on a long ride. Nothing harder on your back and neck than having to hyperextend for a long period of time

Answer 5

just get the most comfortable bike in your price range:)
