Trying To Role My Pelvis Forward as suggested...(15 posts)

Trying To Role My Pelvis Forward as suggested...Mr Nick
Oct 16, 2003 4:28 PM
and boy does it feel strange. It also does quite a number on the boys. I also leveled my seat as much as I could without sliding off the front, but it still crunches the guys. I guess a flatter saddle is in order. Finally I increased my drop from 4cm to 7cm which increased my reach by 1cm. I think if I get this forward pelvis rotation down I will definetly be able to go to a longer stem. I am keeping track of all the changes so I can determine what I really like.

trying to get aero or attempting to get a more energy efficient postion isn't as important as getting comfortable. I know lots of people who are very fast and look like they are riding a cruiser bike because they are so upright. And I know lots of people who've been "fitted by a professional", and they are way too streached out, and unhappy, and they eventually change they're position themselves. Dont be a chump.
Interesting perspective...Mr Nick

and so far I haven't spent the money on the professional fit because I can't decide whether its worth it. Flattening my seat, lowering my bars and increasing my reach are all things that seem to be pretty comfortable and help with power a lot. Not sitting so upright seems to help with my cadence and seated climbing. Also the great thing about adjusting things the way I am is that I can move everything back and I haven't spent a dime.

Is it just the photo angle?Kerry Irons

Or does that saddle have a hump in just the wrong place? It's all personal preference, but I have my saddle (Selle Italia Flite Ti) so that the nose is horizontal, which means the butt is raised a bit. Had my previous Cinelli the same way. Since you're sitting on your sit bones and they are on the but of the saddle, this means no pressure on the nose, and no numbness or discomfort.
yes the hump is in just the wrong spot...Mr Nick

and I wish that I had realized it when I got fitted because he gave me the option of most any saddle in the store. If I put the nose horizontal on this sadlle it does make the but sit high, but for me it feels like I am sliding off and it puts a lot of pressure on my hands.

usually when you roll you hips forward you have to Raise the hbars, to give you enough room to roll them forward. The flexibility comes from your hamstrings to do that, make sure you are not just hunching your back and stretching your arms. i think of the "ideal" position on the bike (my personal ideal - just one perspective) where i am sitting on a chair that is about to be pulled out from under me. Hard to imagine but to get up out of a chair, you have to lean forward, you can't stand straight up. Leaning forward, essentially rolls your hips forward, activates the gluts, making your pedalling/stronger because you are using your butt muscles.

Thats how i try to imagine sitting on a bike.

You don't want tons of reach, don't look at the pros, look at every rec rider in pictures on this gallery and other tour galleries - they always strike me as funny, but then i think thats becuase all the actual photos i see are of pros in cycling mags, keep in mind most people can't ride bikes like them, do what is right for you. Cycling mags have trained us what not to look like on a bike - only a certain elite percentage of people can ride like that. So don't use them as an example. Hope that helps.
I don't think it's really a hump...CurtSD

I have the same saddle, and it doesn't really have a hump - it's really a flat saddle but the nose curves downward. Just base your tilt adjustment (level or slightly tilted) on the back 2/3rds of the saddle, rather than the whole saddle.
no wonder your boys hurt...get a flatter saddle (nm)ColnagoFE

I have that saddle.KG 361

Looks like a Pro-link. Mine looks pretty much the same. No prob w/ the boys. Guess it's all up to the individual. It's the most comfortable saddle I've ever used.
but if the guy is having those problemsColnagoFE

I'd take a long look at the saddle as a contributing factor. Then again maybe his bike just doesn't fit.

Just trying to point out that saddles are a
highly individual thing.

stretch those hamstrings out real good every day for two months. Then you will be able to rotate the pelvis forward without arching your back.

Define "sliding off the front."MShaw

Going back to the guy from www.slowtwitch.com's talk the other month, it went a long way towards explaining my personal observations about saddle positions.

If you're spinning, the faster you spin, the further forward you're going to slide on your saddle. This is partially where the 75-80 degree seat angles came from (among other things).

The slower your cadence, the further back you're going to sit.

Watch some of the pros, they're all the way on the nose of their saddles when they're going all out, and way back when they're not.

I've also found over the years that if I'm sliding around on the saddle its either too high or too low. If I'm constantly having to push myself back to the back of the saddle, it isn't in the right spot.

I've also noticed that if your saddle is positioned correctly and you don't have any major bio-mechanical issues, that your knees are going to track a straight line up and down when you pedal. If your knees are doing a figure 8, your saddle's too low. Ditto if your knees are splayed outwards (this also means that you probably don't have enough arch support in your shoes too, so try that first. It can also mean that your gut is getting in the way of your thighs, lose weight!).

If you're constantly fighting your cleats, trying to get your foot straight and running into the stops on your pedals, something's wrong. Either the cleats aren't positioned right, or your saddle height is off. (or there's something bio-mechanically wrong)

Since I can't see you riding your bike, I don't know exactly what you're talking about, so take all of these recommendations with a grain of salt.

I'd say to define what you mean about sliding off the front, level out your saddle front to back, then take some pictures (with someone else) holding a plumb bob at the ischeal (sp?) tuberosity to see where the center of the pedal spindle is.
