Fitting Your Bike Are you confused about how you should fit a bike to your particular body dimensions? Have you been reading, found the terms Merxx or French Fit, and don’t know what you need? Every style of riding is different- in how you fit the bike to you, and the sizing of the bike itself. It’s more than just measuring your height, reach and inseam. With the help of Bike Fitting, you’ll be able to find the right fit for your frame size, style of riding, and your particular dimensions. Here ya’ go…..the location for everything fit related.

Fitting Q's

So I am searching for a new bike, this time as a nice one. Time to graduate from BSO's! Specifically, I'm looking to get a classic style, upright sitting "roadster" type.

I am 5'3" tall (nominally) and my inseam appears to be 28". This means I need a frame with a seat tube of 48cm. However, there is a complication!

I have a congenital defect in which my Achelies tendons are too short. They simply do not let me stand "flat footed", and subsequently I have no "dorsiflection" - the ability to pull my foot upwards to my shin. The angle I'm stick with is a range between 180 to 45. Sucks hard.

The extra "lift" I get from being on the balls of my feet every time I'm standing appears to be 2-3". So really, I'm a 5'-5'1" guy who happens to be on his toes. This also means my "inseam" is really more like 26".

So in doing the measurements, I know my stand over height gives me the 28" I measured above. Should I do any other measurements with the "corrected" height, which takes into account the extra lift? Or should I just count myself as the height I stand, regardless?

Also, how much does tyre size change fit? I.E. if I have to go with a 51cm frame (looks to be the next size up), would it make a difference between using 28" wheels vs 26", or are there other mechanics in question?

A big tire gets into Toe clip overlap problems as the top tube reach has to be shortened,
in relation to the size/seat tube length .. smaller bikes are shorter too.

but the front wheel needs more length to not interfre with your feet , turning at Low speeds

small-big is a problem.

A Nice Bike without getting into these problems : Bike Friday, & accept the Small 20" wheel .

they have a toll free number, to dicuss the needs with a consultant to get the ball rolling.
and the Eugene Oregon Based company is a flexible JIT, manufacturer,
so the Bike is made as the Order comes up in the queue. .

and will do alterations for other than the average rider .

as you have special needs , they would be the path I would reccomend ..

it will be a bike Made For You, individually.
