Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Sizing on a Masi - Is bigger better?

I am 6'1" with a 32.5" inseam. I am getting a Masi Speciale Commuter (http://www.masibikes.com/cycles/speciale_commuter.php). I've been to two places and each one had a different opinion about sizing me for the bike. The one place said I should go smaller i.e 53 or 56 and the other said 58 would be the best option. I am not sure which one is right because I tried all three sizes and with the seat adjusted they all seemed to fit fairly well. What would be the best size for me? I am also considering the Masi Speciale Fixed (http://www.bikeforums.net/newthread....ewthread&f=178) ... I just can't make up my mind between these two. I will be using it mostly for commuting and riding around in Chicago.

Is that your rider's inseam? In your cycling shoes, feet about shoulder length apart, from the floor to your crotch?

You only need about an inch of clearance for your stand-over height. It's easiest to figure out with that measurement.

inseam is not an indication of bike fit, torso and reach is more important. based on your height, i woulds say the 58, which has a effective top tube of 57.5. 53 is unquestionably too small.

I'm 6"2/3 with an inseam a tad longer than yours, and I ride a 60-61 very comfortably. You probably want the 58, but you may have to do some tricks with the stem angle to make it friendlier to your back/hands on your commutes.

+eleventy. Go by how stretched out and how far down you are reaching, not by your legs.

Stem length, seatpost setback will change stuff too.

For those of us with short legs relative to the rest of our bodies, this is a real PITA. Generally speaking, a frame with an appropriately long TT will have a stand-over height which is in direct contact with one's biscuits.

If I had longer legs I would be more than happy to shop according to TT length, as stand-over wouldn't be an issue, I would be at least an inch above most any bike with an appropriate TT length for my body type. but as it stands, most any bike with an appropriately long TT will ding my dong, so I have to get the biggest bike I can stand over and adjust the reach at the stem. Meh.

Their track model? I already bought an IRO Angus, 53, which I am building up right now. 53 Lemond has a ~30.9" stand-over, and a 545mm TT vs. 30" stand-over on the IRO, and a 540mm TT. My rider's inseam is about 31.5", 32" if I really jam that measuring tape into my nethers.

I'd rather have that inch and a half of standover than half a cm of TT.

It was half-sarcastic... their frames have notoriously long top-tubes. If I were you I'd get a frame with compact geometry, like a Kona P-Wagon.

Thanks all for your comments ... I test rode both the Masi Speciale Fixed and the Masi Speciale CX yesterday and low and behold after the bike guy (Doug at Upgrade Cycle Works in Chicago - they rock) took my measurements and fed them into the computer, I ended up fitting fairly well on the 53cm on both these bikes ... who knew???? I guess girls are built differently. In any matter just to be on the safe side they ordered a 56 cm in the Masi Speciale CX for me to try before I purchased it. BTW the Masi Speciale CX kicks ASS!
