Do your knees brush the top tube?
 
Just wondering if it's a usual thing to have your knees brush the sides of the top tube...

Don't know. You may want to ask in the road cycling forum.

Yes, occasionally, but I couldn't be farther away from being "pro".

I asked one of the guys in my club who's ridden competitively in Europe about this a couple years ago. He said it's not a power generation technique, but rather a way of being slightly more aero.

Mine do not, nor can I imagine how this would be normal for anyone who isn't some knock-kneed geek.

It's simple, turn your heels out, your knees come in. And, vice versa. I sometimes play with my feet to see how aero I can get my legs. I have brushed the top tube. I found my most comfortable position, my right knee in, left knee out. Unusual.

I would wager that your pelvis may be crooked.

No fireballing on this one because of your nifty play on words. :thumb:

What frame are you using? An increasing number of designs these days use top tubes which are really wide to promote lateral stiffness. Personally I don't typically brush the TT on any of my bikes except for the Giant TCR Advanced SL I had earlier this year... which really annoyed me to the point where it was a major contributing factor to me selling it half way through the race season. Was it superbly stiff? Yes. Did that stiffness make me go any faster ... No. ;)

Using a Madone 5.2 2008.
In actuality, i was out riding this week and paid more attenion... it's more of the inner thighs that rub and occasionally the knees.
I deserve to get flamed for this one.

Similar problem I had with the Giant. Nothing you can do but decide if it is something you are willing to live with or go with another frame. Riding as much as I do it wasn't something I wanted to continue to deal with when there were other options. With the giant I would also rub my knees against the "massive" headtube while climbing. I've never had any stiffness/steering issues with any of the standard 1 1/8 steerer tube equipped bikes out there and so went back to something which allowed me to ride hinderance free. :D

Aah. Those things that are rubbing the top tube are often referred to here as guads.
One of the many drawbacks of becoming a pro cyclist.

I won't feel good until I get flammed... someone please... help... flame away... :o

Just how big are those thighs???

FYI - the local cycling club teaches my kids to have the knee as close as possible. Guys says (in 1/3 French, 1/3 Letzebeurgish and 1/999th English - the rest if blank air time as he thinks) that it is primarily the "vind" and also because of the position of the foot and comfort on longer riders like stage races.

LOL well not that big, certainly not enough to challenge Andre Greipel for a title.
