I’m using a road bike with clip-on aero bars and have changed the bike to more of a TT setup to allow for the aero position. Seat foreward and up, 165mm cranks instead of 172,5 and a longer stem. When riding in the TT position however, I feel my quads are getting significantly more work versus ridi…

Try a test. Pedal along in aero until you feel the loading build. The keep same power and cadence while you move up to the hoods. See if the opened hip angle changes your loading,

I try to mix in aero bits in my TR workouts, so I have a pretty good feel on the difference between upright and aero for a given power. Upright I almost never have any issues feeling the quads, not even on this week’s Carpathian Peak +2. However when in aero the quad dominant feeling already starts …

Then that’s a sign the drop may be more than your body is ready for now. Might try to raise it a bit (to max aero height?) and work back down over time in smaller steps.

It is perfectly normal that your power output in your aero position is different. There are many factors, some might simply be that your muscles haven’t had enough time yet to reach the level of efficiency you have in your road bike position. For me it appears to be a mix of general discomfort cont…

Thanks for the help guys! I feel my aero position is pretty okay as far as comfort and power goes. For reference, I have no problem sustaining the position for an hour or even more outside. Power in aero is definately a bit lower in aero vs upright, but not too much I think. I’m regularly able to d…

I have a similar problem and maybe a answer for your question… Many times, during past three years, I got into the state of having spasms/cramps in my quads for a days (maybe even a week). The last spasmy-crampy period was like a week ago. The common thing among all periods is using my TT bike too …

Can you get someone to take a photo and post it? Riding in the TT pos is a learned position you use slightly different muscles and pedal technique. Where is the saddle position over your BB or forward of the BB? Once you have a good pos then your body will adjust to it. being able to put out power i…

Thanks. Don’t have any photos atm, will see what I can come up with. The tip of my saddle is currently as far foreward as I can get it and is 6-7cm behind the BB. Being a road bike it’s unfortunately not possible to get it any more foreward. Tip of saddle to arm pad drop is around 8cm, so not tha…

Is your seat post a set back post? You might want to look into that. Power transfer is ideally over the BB 6-8cms behind is what could be causing your quads to over work. What size crank are you running? Your saddle height compared to your road bike height might need adjusting as well. Because of …

Using the standard seatpost that came with my bike, a Giant TCR Advanced. Crank size 165, because the standard 172.5 was restricting breathing too much. Compared to my road bike position, I shifted my saddle foreward and up to account for the change relative to BB and crank length. Getting a new …

I got down to making some photo’s of my TT positionand I’ve put em up in the Bike Fitting Mega Thread:

Also did a close to FTP type effort in TT position today and I could definately feel an improvement. Less quad dominance and I could feel my glutes/hams do some work.
