Odd, Bouncy in the Drops?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Odd, Bouncy in the Drops?

I can spin up to 115-120rpm while on the hoods or tops just fine. but anything over 105 rpms (sometimes 100rpm) in the drops I get all bouncy sally. I thought maybe I need a bit more practice at higher rpms in the drops, so I did just that. I still get bouncy?

Now its not really a problem as I dont ride at that rpms for the whole ride, its just more of an annoyance.

Am I doing something wrong? Or do I need to just not think about it, and it will go away?

try focusing on pulling up on the pedals more at higher rpm's.

are you positive that your saddle height is correct and that the bike fits correctly regarding reach? 1 cm of mis-fitting can make a big difference in your performance.

Yup. Sounds like there's some saddle positioning issues here. Most shops tend to put saddles too high, and stretching for the pedals is more difficult in the drops, depending on flexibility. Therefore a rider in the drops will bounce/rock more for a saddle that's too high.

Bouncing is usually a sign that your saddle is slightly high. It may be that getting in the drops is rotating your pelvis in such a way that your legs have to reach a little further. You could try adjusting the saddle height or angle to fix this.

Maybe my saddle is too high. I have never been professionally fitted, and still working on my fit by myself based on "feel". (I know, I know, once funds are available I may get a fitting)

I did have a lower saddle about 1-1.5cm lower and started to get IT band pain. Raised it now its gone. I cant recall if the bouncy in the drops was happening then?

I do pedal with my toes slightly pointed down. Been trying to break the habit. At first i thought it was because the saddle was to high so lowered it and like I said IT band started acting up.

I also thought it was because I was kneeing my fat self in the gut, so added spacers and raised the bars. Still was bouncy, but found my body liked the higher bars so i have stuck with it.

Focus on pedaling in circles not up and down like a piston.

I do one leg drills when I remember, come to think of it I never tried them in the drops.

Ok, back on topic - how about seat front-to-back positioning? Where might that fit in?


Sallie forth! It's a good day to ride. (ooops mixed up the metaphors)

Front to back?

Last month I moved my saddle back about 2cm, but can say that I was bouncy in the drops before that. Me knee is behind KOPS. When I tried KOPS I would naturally just scoot my but back anyways to get behind KOPS, that just put me in a uncomfortable spot on the saddle.

You're talking about big changes to saddle position. If you're experimenting, move the saddle by no more than about 2mm up/down and 5mm fore/aft at a time.

KOPS is a load of rubbish by the way - it is a rule of thumb that's not supported by actual evidence.

Not sure how the saddle could have anything to do with it. When I first started riding I had the same problem. An ex pro that worked at the shop told me at high rpm's to work on pulling up more than pushing down. He told me the pushing at high rpms was causing the lifting action. He said pulling up would pull you down into the bike and counteract the bounce. I tried it and it worked for me - I was able to up my cadence by 10 - 20 rpm if I remember correctly. Anyway try it and let me know if it helps.

the weird thing that perplexes me is why I can be perfectly smooth while riding the hoods or tops at 120rpm but when in the drops its a whole different ball game?

Do you think that when I go into the drops I might exaggerate the rotation of my hips?

my best guess is that you are distributing your weight in the drops so that you have less weight/force over the pedals.

That sounds like another good reason.
Like I said its not really an issue more of an annoyance, and only a few times a ride will i get into the 120+ cadence and when I do its only for a short time.

Moving the saddle 2cm back is the equivalent of raising it almost 7mm. The fact that you don't appear to understand this relationship makes your next comment all the more predictable.

Given what multiple posters here have said about saddle height and stretching to the pedals, I don't know why this is so perplexing still. Either use the advice here and in other sources and see where it takes you, or go have someone fit you.

Yeah, ummm, I just posted the question this morning and still haven't gone home from work. Its kind of hard to test out the advice given when its only been about 6 hours since asked.


I thank everyone for the help, even you disgruntled Banzai.

You need to adapt to the position. It's easier to spin fast when you're more upright because your hip flexors engage more. With training, spinning in the drops will be as easy as the other positions.

I believe the answer is a combination of the above things many have responded to. Riding in the drops closes the hip angle. This changes the position of the pelvis on the saddle...sit bone touch down is more forward. Changing the pelvis interface to the saddle changes effective leg length. If the OP is close to full extension riding on the hoods with more open hip angle than closing the hip angle will cause the hips to rock...just like raising the seat too high with hands on the hoods.
To me, best saddle height is a balance between leg extension on the hoods and in the drops.
A further issue relates to how one rides in the drops. I would say that many better cyclists when trasistioning to the drops open their hip angle by riding the rivet aka scooting to the front of the saddle. This effectively lowers saddle height and opens the hip angle compensating for the addtional stretch to the drops.
Hope that helps.

Sorry. That's the problem with asynchronous communication. And an occasional disgruntlement over some of the silliness on this board, and in real life.

My apologies.

Consider your saddle height, and the fact that the significant aft move you made does equal raising your saddle about 7mm...a fairly significant height change.

dude, seriously? he probably hasn't had time to even ride his bike since he posted this. Suggestion - might want to switch to decaf.
