Bianchi Volpe Sizing
 
Hi all, looking to get my first serious bike. I am looking for something that can be ridden around town, on not so perfect roads, will give me a good workout, and also allow me to carry something small on the back (assuming I get a rack). The Bianchi Volpe seems to fit the bill quite well, but I am confused about sizing.

So far I have test ridden a Trek hybrid and road bike in a 56 (fitted on this by the LBS), and a Bianci Volpe in a 53 and a Bianchi Via Nerone (I believe it was called) in a 53. The Bianchi dealer did not have any 55s, and never mentioned having me try one.

I am 5' 10", with a 30" inseam, and am concerned about getting the wrong size, as I will have to order. Any thoughts on the 53 vs the 55 for me?

I am also planning to take a look at the Bianchi Camaleonte and Specialized Tricross this weekend to compare.

Please let me know if I am not providing sufficient details, and thanks in advance for your responses!

TWO measurements are critical to start -- standover height (does your 'jewelry' touch the top tube when you straddle the bike?), and saddle height when properly adjusted (I use the heel-on-pedal method), making sure it doesn't take too much seatpost.

Pretty much all factory bikes have published stats and geometry on their websites. When you test-ride bikes, these are the first things you check. When you find one that feels right (or really CLOSE), get make/model/size, and go "Googling". Match those numbers as close as you can to the bike you're looking at.

I've ordered my frames online and built them up myself for a decade now; I know without measuring by now what geometry I need.

As long as you're going to do business with them, your LBS should help and support your research.

Thank for the response. When you reference the standover, should I be toughing the bike or have clearance? How much clearance?

Thanks!

You really don't want to be touching the top tube with ANYTHING when you're straddling the bike (although there are others here who say that's BS -- personally, I'd prefer not to). Old wisdom said that a fist between you and the top tube for MTB was proper, and 1-2" for road/cyclocross/hybrids. I'm of the opinion that, as long as you can slide off the saddle and not hurt yourself, you're good.

Tanks for getting back to me, appreciate the response and insight!

One More Measurement Of Interest...
 
While I acknowledge DX-MAN's timely response and helpful attitude, I must disagree insofar as he ignores what many consider the more important measurement in fitting a bike.

And that is the [effective] length of the top tube plus the reach of the stem, which give the proper handlebar relationship to the saddle. The right starting point for this is a bit more difficult to discover for a new rider, because you can't simply measure from a bike that you know fits you correctly. Have your bike shop explain the top tube length and stem reach for a bike that feels like a good fit for you (after having ridden it outside and on a trainer under a fitter's supervision). That measurement must factor into your purchase decision.

For me, at 6' 3/4" tall, with a slightly longer torso, the proper combination of top tube + reach = approximately 68.5 cm. That's for a horizontal top tube, measured center to center, and a handlebar height that's only a few (4-5) centimeters below saddle level. So a 58cm frame size, with a 57 cm top tube, wouild require a 110mm stem, approximately.

The standover and seatheight measurements matter, but not so critically, as there's more room for adjustment. Some can ride a bike with little to no standover or a very long seat post showing. But with the wrong forward reach...it won't fit.

Not knowing the geometry of the bike in question, I'd stick with the 55 or 56 until you discover what feels correct to you. Then take your correct measurements from there.

My two cents. Good luck.

I've test-ridden a 55 Volpe (can't find a 53). I'm about 5'9" and 33.5" inseam. The 55 is all up in my family jewels, not something i'm comfortable with. They extension I get on the bike, however, is fine. If I were getting the Volpe, i'd most likely order a 53 and perhaps switch out to a slightly longer stem if I want more reach.

I don't know if Blake686 has bought the bike yet, but the Velope is a wonderful bike. I'm 5'7" with 29.5" inseam, and the Velope 51 fits me great. BTW the Velope is great for what
Blake686's requirements are plus some. BTW I'm looking to add Bianchi Vigorelli. I like the Velope very much, but I love to ride race type road bike. I think the Vigorelli will fit my requirements much better. I'll retain the Velope as my errand and all purpose bike + tourer.
