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)

Motobecane Fixie Cafe - Geometry Question

I am looking for a bike for my wife. She's short and has already been fitted at an LBS. The bike I am interested in is from BD (NEW Motobecane Fixie Cafe). I was looking at the geometry but something seems really off.

Geometry: http://www.bikesdirect.com/products/...fixie-geo.html



Bike description: http://www.bikesdirect.com/products/...-bar-bikes.htm

The stand over (SO) is 501mm for a 43cm bike ... is that possible on a 700c bike with a 'sort of' horizontal TT? The other SO numbers look super low too.

Photo of the bike:


-------------------------
UPDATE: I've checked with BD (who checked with Motobecane). SO for 43cm is 685cm. Must be a typo on the website. I know the question must have seemed ridiculous but I'm a bike noob.

That's just a bit over 2 feet. Yeah that's wrong.

Approximation, right? 12 x 25.4 = 304.8 6mm per foot.

OP: I think what you should do is go back to LBS and buy a bike from the person who spent time sizing your wife to a bike and answering all your questions.

+1

A few weeks ago we had a guy in the shop for about two hours asking questions about sizing, differences in components, etc. He wanted something with track geo and had similar proportions as me so I put my Bare Knuckle on a trainer, had him get on it and made a few adjustments. I even switched out the stem to something shorter because his arms weren't quite as long. He left knowing a lot more than when he came in. I even wrote it all down for him.

He came back the other day with a ****ing Kilo TT (that was too big for him), complaining that the "crankset was slipping".

gross.

somewhat similar, I work in the auto industry on a dealership level and there is nothing I hate more than when a customer comes in for a repair or concern and explains to me how it 'shouldn't take that long'

apparently a persons expertise is free now. because internet.

That's the difference between retail and commercial businesses. As a professional engineer, only paying customers received any consulting advice from me.
