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.

Please help me with fit (video included)

Hi!

I did some work when buying a bike - put my numbers on competitive cyclist calculator and came out with 56 frame, so I bought a bike from a friend - may be I had to try more bikes but whatever. All measurements are close to what that site calculated for me except saddle to handlebar (it's like inch short). Bike feel great except one thing - I believe I put too much pressure to my hands so my pinky feel numb even after hour or two of biking. I understood there's could be a numerous problems that lead to that but I want to start with a fit/riding position. Bike is trek 2100 56cm.

Here's video: http://www.youtube.com/watch?v=EJPul6yJqkc

here's my numbers. Thank you so much in advance.

Do it over in bike shorts showing your legs and with feet on the pedals.

Your saddle looks like it needs raised. Get that right and then review again.

I agree, your saddle looks too low.

Have you tried to do the heel on pedal method, as a basic fit check? It's probably the lowest your saddle should be. But for the reasons below, it's not the last word.

Also, perhaps you should recheck your inseam measurement making sure you have the longest possible measurement - get the book really pulled up hard in there. I'm just under 5'6" and my inseam, true pubic bone height, is 32.2 cm.

Also, if you have long feet or a forward cleat position, your knee will be bent more than for someone with small feet for the same saddle height, even more so if your thighs are long. This just proves that pure vertical measurements aren't necessary the last word.

At the same time you can just go out for a long ride or trainer session and see if you have pain on the front of your knees. For me that's a sure sign to raise the saddle a few mm at a time. The height at which knee pain ends or never starts but not high enough for painful hip rocking, is the correct height in my personal experience.

Thank you guys! This is a clearly friendliest forum on internet, and I saw many.

I raised saddle and no numbness in pinky anymore since there's more weight is put onto pelvis. I biked 3 hours today and feel great and energized after ride, that's always a good sign. I do not like to raise it anymore since mounting and unmounting sometimes struggle for me, since I am total newbie (200 miles on road bike)

Thank you again

Congrats on getting your weigh shifted off your hands.

Mount over the top tube, rotate one of the pedals to the 2 o'clock position, click in to that pedal, then step up on to that pedal and place your butt on the seat (you should be moving at this point). Now before loose momentum clip the other foot in and off you go. You can tilt the bike slightly on its side when placing your leg over the top tube. This mounting method allows you to have the correct seat height and still mount/dismount the bike.

When coming to a stop unclip one of your pedals and stand over that foot while rolling, then right as you stop shift your weight over the top tube and step down to the ground.

Sheldon Brown's site has a good article/video on the technique http://sheldonbrown.com/starting.html
