Quote | Reply
Hi, im currently a college student who cannot afford a bike fitting near me. Am attempting my best self fit, and have seen many people get helpful insight from these forums. If anyone would be generous enough to help, that would be amazing. Thanks.

first thing about a bike fit thread is how to take the video. Camera should be center of mass, about hip height. It helps to not have a backlit situation too, so take it at night if you were to take it from that same position.

We can't help you as well with the video you gave us.

Where are you located?

yeah that camera needs to come up and to to the left and then be rotated to be square to the bike

What saddle are you using?

Please take the reflectors off the wheels.

I'm not proficient enough to comment on that fit, but maybe (for video quality):

lose the baggy shirt
look forwards occasionally so we (I mean they) can see your head position

Also some vital stats data might be useful:
your height and weight
saddle height
saddle type
bar type
crank length
frame size
Current pad x/y (if you can find a tape measure)
Goals / race distance

Haha. If I haven’t already stated I’m uneducated I’ll state it again. Sorry I didn’t have the reflectors removed as soon as I picked this bike up as a hand me down, and I’m sorry that my shirt was too baggy.

Also don’t forget to put helium in the tubes-makes your bike lighter and 15% faster 😜

the shirt comment was so his torso position can be observed more easily

A baggy shirt or a tight shirt doesn’t stop you from seeing the angle and alignment of his back.

Looks solid. Only thing I'd certainly recommend you do is I'd move the extensions forward relative to the pad.

Hard to tell how open or closed the hips are with a baggy shirt. It was a good recommendation and will likely improve the feedback he'll get.

How does the position of your belly affect how open your hips are? I can understand the angle between your back but below that (being your belly) doesn’t affect the angle. It’s like saying my hip angle changes by pushing my belly out?

It affects how much angle you need. Structurally, yes, the angle from the head of the acromion to the top of the femur to the knee joint is the same, but how much actual clearance you have is not.

I will have a better video tomorrow with a better shirt on and the reflectors taken off. HA. Thank you guys for the criticism, you must learn somehow.

Here is the new updated video. Tight shirt, along with the reflectors removed to keep the people happy. Thank you in advance for the help.
I'm 5'11, 171 lbs, 21 years old (today is my birthday, this bike was a gift), 56 frame, 32.5" inseam.
Thanks again for taking the time to help me out.

The extensions need to be moved all the way forward (but preserve the current armpad position). That means you need to loosen the armpad mount, loosen the extension mount (to the base bar), push the extension mount as far as you can (with about 1 cm or so sticking out of the back), and then move the armpad to the same position relative to the saddle.

That should give you a longer distance from the edge of the armpad to the end of the extension. Your arms should be then a bit more forward on the armpad, extending your reach.

Once you do that, I'd angle the extensions up a couple of degrees. That should get you pretty close.
