Let my position have it, I’m getting crazy trying to accomplish a decent fit on my bike.
Sorry for the crappy picture, mom did her best job
It may be an illusion due to camera angle but you appear to be long in the leg, which has you a bit stretched out, I’d say try a bit shorter stem as long as your knees and elbows aren’t bangning. The other option would be moving your seat forward a bit, but You knee angle on the top leg already looks pretty compressed so the stem would be where to start, and then maybe a bit of seat forward, as long as no knee issues or power drop occurs from being over compressed at the top of the pedal stroke. Height looks pretty close.
Of all the decals I’ve seen on bikes, I think “Lipton” iced tea is a new one.
My vote goes for shorter stem.
I do have long legs, 5’11’’ 37 inseam. I was riding a shorter stem and appear to be way too slack on that one. Check out my previous position here and let me know what you think. http://forum.slowtwitch.com/gforum.cgi?post=2363174;search_string=;#2363174
I would go back to where you were before. You look pretty stretched out in this position which will probably cause some lower back pains in the near future (I had the same issue). Your older pic look good, but your seat post may have been slightly too high, and I probably would have taken a 5mm spacer out from under your stem.
Thanks for replying. I make changes based on some comments that I wasn’t having any aero advantage/benefits on that position
Anyone else?
Hey, nice improvement over your old position:
Stem is flipped and lowered, and generally you look much lower. If you can put out near the same power in this position as the old, you’ll definitely be faster!
I think that my suggestion from earlier is still worth considering:
(1) push the saddle a bit further forward
(2) pull your aerobars back (so you’re less stretched out) and widen them so your knees track between your elbows.
You obviously have very long legs, so you basically have to choose between (a) having a stretched out cockpit (which you have right now) and (b) having your legs track between your elbows (which I believe you should consider). Maybe it will work, maybe not. It’s worth a try, IMO.
At any rate, your position looks a lot better than last time. Best of luck!
Hi Rahzel thanks. The picture you are refering to is actually my PREVIOUS position, I changed to the one you commented in past days, because I was tell I wasn’t any aero.
I’m going now back to my old position and see how I can improve it just a little bit. Thanks for your suggestions.

Oh ya, I know My comments in this thread are in reference to your new position–the one you posted in this thread. I still think it’s worth a try to go to the “track” position, but if you feel otherwise, or it’s uncomfortable, no big deal.
Can I get some xtra love from the ST family or hate? Is 20cm of drop ok for and age grouper?
**Is 20cm of drop ok for and age grouper? **
The drop is OK as long as its comfortable. I’ll echo what other folks have said…the first photo looked really stretched out. From what I’ve read on fit, you want close to a 90 degree bend in your arms.
Take a look at this article from Bikesport Michigan, and compare some of the “before” and “after” pics to you…might give you some ideas.

Hi there, I pull the aerobars back to get a closer to 90deg elbow angle, but I realized my seat is in the maximum forward position it can be, no way to go from there. I’ll need to ride like that until I find a forward seatpost right?

Hmmm, yes I think you’re stuck riding that way until you can find a forward seatpost. However, you may not actually need to buy a new seatpost! What you can do is practice riding on the “nose” of your saddle. This will move your body forward without actually having to move the saddle forward.
If this isn’t comfortable for you, first try playing around a bit with the angle of your saddle–tilt it a few degrees up or down. If that doesn’t work, try a new saddle if you have one sitting around. If not, don’t worry about it too much–you’re already in a pretty forward position for your height.
Looking forward to seeing future iterations of your position!
I don’t understand why the pictures on the link are “good fits” from what I have read here on ST.
-In the woman picture , seat looks to be high notice her feet pointing down.
-Neither of them have flat backs
-They both seem to be riding very slack
-They’re both very upright
-I’ve read from slowman that anything in the 145-150 knee angle is ok, they called 147 way low.
Just way I got out of the article, thanks for sharing…
If you are online right now I can send a pm with a picture of my current set-up.
Kinda slow day at work. We have some CAD software at work so I overlayed some angle measurements to your picture. Please keep in mind, I’m no bike fitting professional, these are just my observations.
A couple of notes:
-
Your knee angle measurement using the greater trochanter, knee apex, and maleolus is 148 degrees. In Slowman’s article on Seat Height (http://www.slowtwitch.com/.../Seat_height_21.html), he suggests a range of 140-150 degrees.
-
Your hip angle measurement from the pedal spindle, trochanter, and clavicle is 91 degrees (assuming your leg is bottom-dead-center and it was a bit hard to guess your clavicle because of your shirt). In Slowman’s article on Hip Angle (http://www.slowtwitch.com/...em/Hip_angle_24.html), a suggested range is 95-105 degrees. Your measurement is a bit shy of this range.
-
The angle measurement of your trochanter, clavicle, and elbow is 97. Again referring to Slowman’s article on Cockpit Length (http://www.slowtwitch.com/...ckpit_length_22.html) a position that ideally supports your upper body is 80-85 degrees. Your a bit over that target.
In order to hit the ranges for hip and cockpit, I think maybe moving your seat forward or maybe flipping your stem, so your aerobars are higher up may work. But again, I’m not fit guru. These are just my observations from reviewing Slowman’s articles.
Good luck this season w/ your races.
Peace,
Rob
Hi man, that’s awesome thanks. I actually have a recent photo from yesterday with a worked out position are you willing to put some angles on that one? I can send it right away if you provide me with and email. Thanks again…
No problem. I’ll shoot you a PM w/ my email.
