Bike Sizes
I recently tried some bikes. A 19 inch frame is my proper size but
when I try a 16 inch frame it doesn't feel really small to me but the bike shop owner and my girlfriend say that a 16 inch frame looks small for my height. That may seem true but I felt more comfortable on a 16 than 19 inch frame. It could be because I used to ride BMX and those are tiny. Sure I'm 6 foot tall and can not ride BMX anymore but the 16 inch bike is between the BMX size and 19 inch frame, but closer to the 19 inch. I just feel that I get more monuverability and feel more comfortable on a 16t inch. I like bikes that are a bit smaller than what normally I should be useing. Do you guys ride bikes that are the perfect fit for your height or do you guys ride bikes that are smaller and why? Thanks, James |

Search this newsgroup at groups.google.com to find loads and loads of information on fitting, and links to fit calculators. Numbers? You're six feet tall, right? Are you riding a 17 inch frame? I'm probably 5'10" or so. The frame in question is a Giant TCR2 compact frame in "Medium", which I think is supposed to be equivalent to a 55cm. Huh? A "medium giant"? No conflict there? Actually, according to Giant's sizing web page at http://www.giant-bicycles.com/us/050...50.600.100.asp it is the correct frame for me, but I suspect a larger frame would be more appropriate. Hah! They offer a small giant. Maybe I should start a bike company called "minuscule" and sell large frames. My LBS looked at me and said 17.5, but the bike seemed small to me. I'm 5'9". Mountain or road? MTB sizing is generally done on the small side, and that's ok. Road sizing is done small now too, but that's _not_ ok. It makes sense for off-road riding to have lots of extra clearance everywhere and short reach, and so much time is spent out of the saddle and doing weird stuff and flying off the bike into sharp rocks that you don't notice minor size issues. Road bikes, OTOH, should be fit perfectly. I understand that many years ago, road sizing was done too large; that must have been unpleasant. Now they do it too small, for minor weight savings, purported stiffness, and extra-low handlebars. The trouble is that road biking, with so much time and so many miles spent in the saddle in one position, is very sensitive to minor size issues. (Would it be worse to have a bike that's too large than a bit too small? There'd be no way to fix that without sawing off something, eh? g) Depends on exactly what's too large. Top tube height? Replace 700c wheels with 650c. KOPS? Setback seatpost. Reach? Stem. Bar height? Stem. Saddle height? Seatpost. Etc. Modifications can be made to make most bikes fit most people, if sufficiently motivated. Fit goes beyond how your body contacts the bike, IMO. Fit should also include how you're going to use the bike, and your abilities. In this region, a double crank doesn't make sense for beginners, weak riders, people living in extra-steep areas, or anybody not completely sure of their needs. I'm not sure it makes much sense for anybody, but I certainly shouldn't have left that store with a double. In fact, I should have had a sport tourer, or at least something whose geometry is a little more relaxed than the hardcore racer that I bought -- maybe a Giant OCR. I know now...I know a _lot_ more than I did then. I'm nearly "saavy". Unfortunately, bike shop employees tend to be either racer-wannabes (and expect everybody else to be), or don't give a damn, or dumb, or too busy focusing on bringing in the benjamins (how's that for me being hip! to help somebody choose the right bike. This newsfroup should write a training manual for bike shop owners and employees. Now that I've done the hard work of coming up with that idea, it's up to the rest of you to implement it. What, me spend MORE time on it? Sheesh, how ungrateful... BFG -- Rick Onanian |

Hello James,
when you have both feet on the ground, there should be a 2 inch clearance between the top bar of the frame and yourself. Less is dangerous, more will make adjusting the rest more complicated. In essence the bigger the bike, faster you can go with the same effort. Think of those BMX bikes, even with great effort they can't go that fast. "James Lynx" wrote in message om...

No, my LBS said that I was right for a 19 inch frame. I do feel more
comfortable on a 16 inch frame and that's probably because I used to ride BMX bikes (years ago) and now want to get back into biking and feel that I have more control over the bike if I have a slightly smaller frame. I was thinking maybe a 16 inch but yeah that's gotta be mega small on me so maybe a 17.5 if there is such things. Thanks Numbers? You're six feet tall, right? Are you riding a 17 inch frame?

What if we are talking about a compact frame? I have a size 55 Specialized
Allez. I have more than 2" from the cross bar to my crotch, but I am pretty sure the bike fits me. By the way James, don't get mixed up in comfortable, and familiar. You may be more used to the feel of a smaller bike, but it may prevent you from getting the most out of your effort. Jim "Daniel Crispin" wrote in message .. .
