Hello all,

I of course mean the manufacturer, not massive bikes! I'm looking at buying a Giant fcr 1 or gt gtr 4 online (as i can get a good deal) but there's nowhere nearby that i can try one out for size.. If anyone has any suggestions what frame size (i know they have a compact frame) i should be looking at i'd be very thankful. I'm almost exactly 6 foot tall.

Thanks very much!

Giant makes lots of different bikes, with lots of different fits. Buying one without a test ride is a bit like buying a lottery ticket. A $800 bike from a dealer in your neighborhood that fits you like a glove is a bargain. A $400 E-Bay bike that does not fit you is a very expensive bike.

I'm 5'10.5". My OCR3 is a large, just a hair too big for me. My OCR elite is a medium and fits like a glove. I think their newer models also come in M/L and so on in those half sizes, I could be wrong though. But definitely ride them 1st.

I think the Giant web site has a size chart based on rider height. I wouldn't trust it, though. Different people with the same height may have different arm and leg lengths and thus need different sized bikes. My advice, especially for newbies, is to buy what your local bike shop carries. Good fit is way more important than any other bike feature.

I am exactly 6' tall and Giant's large frame fits me perfectly.

I am 5'11.5", so we are probably about the same height. I wear a size 34 pants length, so now you know approx. how long my legs are. I tried out a Giant TCR2 the other day in an M/L frame. It was the tiniest shred of a hair on the small side. But I think it could have been fixed merely by raising the seatpost, so I'm not sure. Either way, I'm looking into a TCR C3 for next summer, and I will either be going with a L or M/L frame depending on which I like more. I'd guess the L though.

I'm looking at buying ... online... but there's nowhere nearby that i can try one out for size.

Echoing what others have said... I wouldn't buy without trying somehow, somewhere. I'm not the most experienced person out here. My opinion was formed by test riding lots of bikes before buying. Don't see how you could ensure a good fit just from basic measurements. Maybe with a lot of detailed measurements, but even then, different people have different flexibility, etc. There's no substitute for test rides.

+1. I'm 6'1" and fit on a M/L. Of course you need to consider your body type, i.e. how much of your height is in your legs. I have a relatively long inseam for my height, so an M\L with very little seat mast cut was the perfect fit.
