I think the group got it right for you OP. Looks like the bars are too close to you (bike too small for you) and the seat is way too low.
Looking at the video again, it's really apparent that you are bunched up and can't stretch out. And the bouncing is coming from your legs not being able to extend to the proper angle.
Good news for you, new bike time.
Tell the Mrs we all said you have no choice!
You could raise the seat and fix the leg issue, but the too short reach issue would remain and could cause back and butt pain as you would still have too much weight rearward on your tenders.
Get a new bike. It's a health issue (you can do harm to yourself riding a bike like that for long periods). Do it.

I disagree about the frame being to small. He is using a 90mm stem so theres plenty of room to play with there. Raise the seat a tad and hes good.

allen254

lol its looks like he has a lot of stack height needs to slam that stem asap.

allen254

it looks fine to me you look upright because you have a lot of stack height on your stem you need to slam/lower that stem,, it felt so much better when i slammed my stem.

loimpact

I *think* there's 2 sentences in here but both of them confuse me.

It's good to feel a little too stretched but you went from 130/120 to 110/100 stems???
and
You're 5'11" and you ride a much smaller frame than the OP?? (OP's only 1 inch taller and rides a 56. What size are you riding that's so much smaller?)

(Maybe I misread?)

TenSpeedV2

Far from any sort of expert here. The bike looks a bit small, and the first thing I saw is that you are not getting full extension on your legs which appears to be causing the bouncing in the video. 6'0" here, all torso, and I am on a 58 endurance geometry with a 90mm stem.

GravelMN

IMHO, raise the seat a cm or two and work on rotating your pelvis forward to flatten your back. Raising the seat should reduce your bounce and make it easier to get the proper tilt to your pelvis. This in turn will make it easier to get some bend in you elbows.

Lazyass

If you can't naturally tilt your hips forward and bring your back down see if you can find someone with a longer stem to try out. IMO you should have bought a 58 but you can get a 56 to work. I'm 5'10" with a long inseam, my most comfortable bike is a 57 but I also have a 54 with a 120mm stem that fits fine (it was on clearance and the only size left). With the original 90mm my posture looked like yours. You may be comfortable on normal rides but long distance you'll probably get pretty fatigued, especially your upper body with all that weight on your hands. You just need to be stretched out a little more. In my opinion.

WTF! Why are you folks telling a guy with straight arms and a 35 degree torso angle (up from horizontal) to slam his stem? That is absurd. I certainly wouldn't do anything else before I bent my arms if I were OP. Then the saddle up. Then reassess.

Lazyass

He doesn't need to slam his bars, they're already lower than I would have them. He doesn't need to raise his saddle. He's a masher and needs to work on a smooth pedal stroke with the heels down and needs to be stretched out a little more.

FLvector

OP - aren't you glad you asked?

The recommendations from the BF experts are all over the place, each contradicting the other. People are saying to raise the saddle without even seeing the full pedal stroke since the video doesn't show it. Ask some of the better riders in the CPC group (such as Roly) to take a look at your fit during a ride.

I think your bicycle fit is good. Your riding position isn't bad either. If you're looking for perfection... you need a coach. But otherwise I think you're really good... better than most I see.

Lower back pain is common in mature males. If you were riding a desk chair and your back was "tightening up".... I'd say stand up every now-and-then and do some core exercises. But since you are a cyclist I'll say.... sit up and stretch every now-and-again and do some core exercises.

Just remembering to stand-up and pedal (for no reason) every few minutes may eliminate your back stiffness.

Fiery

Wasn't your first comment that he is "way too upright"?

But yeah, his torso is lower than 40°, his arm to torso angle is at least 90°, possibly more, and all that on a 90 mm stem, yet people recommend going for a bigger frame and/or a longer and possibly lower stem. Amazing.

Lazyass

No, just a longer stem. Speaking from experience

rpenmanparker 

He IS "way too upright". A guy dressed like that should be much lower. The shades alone demand it. Until he bends his arms and tells us how he feels, there is no way to know what should be done to the bike. It is one thing to have a pro bike fit, but that doesn't guarantee you won't adopt an improper position as soon as you exit the fit studio. The fitter isn't your coach, following you in a team car to continually correct your posture.

shoota 

Good lord that's WAY too upright? It looks pretty normal to me. And remember this is my JRA position (i.e. highest), when I'm pushing hard I of course bend my elbows to get a little more aero.

The bike is the right size.

The bouncing could be due to the high cadence (100-105) at low watts. I thought that might make it easier to see the pedal stroke in the video. Guess not.

I don't need to slam the stem. I have short arms. For any given back angle my bars will be higher than someone with longer arms.

The reoccurring theme seems to be "do core work", which I am, but I still can't help but think there is something else going on with my pelvic tilt or something else physiological.

rpenmanparker 

Please take no offense, but why on Earth would you ask folks to critique your JRA position instead of your best aero, workin' hard position? Is that how your fitting was done, using your JRA position?

shoota 

Hmm I don't know the answer to either of those questions I guess. I think the fitting was done in this position yes. It was at least the starting point, the fit was a little while ago so I don't remember if I got into other positions.

rpenmanparker 

Once again, I really just want to be helpful. I'm thinking you may have just stumbled onto the crux of your problem.

shoota 

Dude I'm not gonna be offended, go ahead and say whatever it is you need to say. Should I take another video in other positions or something? Honestly I feel more comfortable in more aggressive positions but it winds up hurting my low back with enough time/watts.

Nachoman

Maybe it's not your riding position at all causing your discomfort. Maybe it's a result of how you sit at work, or something else.
And if you get pain in spot on your lower back, maybe it's some little knot that can easily be worked out by a massage therapist.

WalksOn2Wheels

I see what this is trying to illustrate, but it seems to be two complete extremes. The one of the left, while the lower back is correct, looks REALLY strange because the guy seems to have little to no bend in the arms, pushing his shoulders up and creating an extreme curve in the back. A quick look at pro riders would reveal something in between: pelvis rotated forward like the guy on the right, but an overall rounded back and bent elbows like the guy on the left.

shoota 

Agreed. Heck I ride with several people who look like the guy on the left and have no issues. But I've never seen anyone look like the guy on the right.

f4rrest

Yes, both examples look too extreme.

milkbaby

For sure neither example looks like a proper road cyclist. Shirtless = triathlete
