Hello everybody, im new here. I have been riding a mountain bike for awhile now, and i would like to move into road bikes. Here in New Zealand, the road bikes are quite expensive. I spotted one online for quite a good price, and its brand new. Its The 'Gios Siera Road Bike.' It would only be about $30 NZD for shipping, and the only assembly required would be to put the handle bar on and to put the front wheel on. Would this bike be ok for a beginner? It's '52cm' and i'm 5'3". Any help greatly appreciated.
Gios Siera Road Bike for beginner?

Thank you for the help! If Gios measures the size from the seat tube, what is the conventional way of measuring the frame size of a road bike?
Another thing, Im only 15 years old so I'll still be growing for a little while (I hope!). The seller also sells a 49cm version. Here's the listing if it helps: http://www.trademe.co.nz/sports/cycling/road-bikes/small-52cm-under/auction-506499656.htm . You will think it's very expensive probably, but everything is expensive in New Zealand compared to other places!
Once again, I really appreciate your help.
Most bike sizing is now "virtualized." The customary way of getting the virtual size is by drawing a horizontal line from the center of the top of the intersection of the top and head tubes, to the centerline of the seat tube. In other words, the nominal size would be the actual length of the seat tube if the top tube was horizontal. The method I used was to simply look at the head tube and top tube measurements of this bike, on this web page--http://www.gios.it/bike/?Siera, and compare them with bikes I'm familiar with.
Then I interpolated your size from riders I know and what they're comfortable on. For example, my 5'5" daughter sits very nicely on a 50 cm frame that has a short stem and a top tube of about 52 cm.
Regarding sizing your bike for growth, I can't predict your future. I do know that internet sellers often attempt to widen their audience by suggesting an exaggerated range of body sizes that their bikes will fit. The 54.5 cm top tube of the Siera would be more appropriate for most riders in the 5'6" to 5'9" range.
That is great advice. Thankyuo. Another option has popped up. It's the Gios Al Lite. It's a bit more expensive but seems like a great bike. Here is the link http://www.trademe.co.nz/sports/cycling/road-bikes/small-52cm-under/auction-509011610.htm
Now, I could get this bike in either a 48cm frame with a 51.5cm top tube length OR a 51cm frame with a 53cm top tube length. I'm 5'3" Inches remember. Thankyou!
Good to know, then. Looks like a fine bike. Love that shade of blue.
