Wazza_pe Posted October 11, 2012 Share You should do an online fit calculator to get it as accurate as possible.Without knowing your measurements, and going purely on height, I would hazard a guess at a 48-50 cm top tube frame will be fine. You won't find a carbon bike in the 'cheapo' range, so aluminium is about as good as it will get for you.

Motard660 Posted June 26, 2013 Share I am sitting in the same boat and know nothing about road cycling or road bike sises. I am in the process of buying a road bike, but not sure if the bike shop sales person know as well. All my mountain bikes is medium, but notice on a road bike you get medium to large (M/L) sise as well. My length is 172 cm with leg length of 80 cm According to the online calculator my center to top tube (CT) must be 54cm. According to the Bike Shop my sise of bike is a Medium/50 cm with a top tube of 55.5 cmAnother sise is M/L 53.5 cm with a top tube 57.0 cm What sise do I follow? Red or Blue I hope i make some sort of sense here... Link to comment Share on other sites More sharing options...

You're of a similar height and inseam to me and I've been advised that a 54cm top tube and 52cm seat tube is about right. These are c - c measurements. To ad to the complications the geometry differs according to the intended purpose of the bike. A more relaxed bike will have a sloping top tube, making the seat tube shorter. But on a normal road bike frame with a fairly straight top tube I'm a 54 top tube and 52 seat tube. I'd guess you would be similar. Link to comment Share on other sites More sharing options...
gummibear Posted June 26, 2013 Share Then also what are road bike frames made of? you get carbon frames and what else? Steel and Ti Go for a proper bike set up so you know what to start off with. Link to comment Share on other sites More sharing options...

Size bike for me is a 52/54. Measured by Cycle Lab. Just in adding the MTB sizes are completely different to Road Bikes. See if your LBS will let you test ride one before buying. Last thing you want is a bike that's either too big/small and you end up with aches and pains in places you never knew you had! Good luck. Link to comment Share on other sites More sharing options...

Also dirty (not dusty) roadbikes more than likely means the previous owner didnt take care of it. You cycle, so I guess the basics remain the same, perhaps MTB's have more scrathes and so on but you'll quickly see if its a dodgy bike or not. Are u buying "used"? Ask to test ride it. When wife and I started road cycling we bought used "cheapies" and the addiction took off from there. Bike size...see posts in this topic for your answers. Good luck.
