All,

Does anyone know the Q-Factor on a 2021 Trek Domane with a Ultegra Di2 group?

Thanks much.

Glenn

Unless I am mistaken, the Q-factor is a property of the crankset. Shimano lists it at 146mm.

Or you could actually measure it yourself.
Distance from ref. point on crank to the ST X2 + ST diameter.

That sounds really low. Has Shimano changed its ways? I had an early 105 aluminum Hollowtech with a Q-factor of ~165. I brought that bike down to 144 but hat is with an old, straight Sugino crank and a short Phil Wood BB. (My knees would love for you to be right. I couldn't find the Q-factor on your linked website.)

I didn't see it initially at first, either. At the bottom of the page cited, scroll down using the arrow.

Amazing how companies spend huge money of putting all sorts of scroll bars, animations, and videos in their websites - when it adds nothing and actually makes the information HARDER to get. Sigh...

It's actually Shimano's website.

You need to click the arrow:



Then you can see it:

I haven't bought it yet. Want to compare it to my current bike. I'm currently using Shimano +4mm pedals and a 1mm washer on each side.
