I have never put any consideration to KOPS on the tri bike. Just figure out how low you can go, then adjust to have shoulders and elbows close to 90 degrees, that’s it.
Do many follow the KOPS rule when in TT mode?
No. KOPS is at best a rough rule of thumb that’s convenient for doing quick-and-dirty road bike setups. When it comes to TT/Tri aerobar fits, almost everyone should be significantly farther forward than KOPS.
Even when it comes to road bikes, it’s very vague and has no theoretical basis, and it’s not something that should be part of a serious fitting process.
Good to know, thanks everyone. I’m able to move my bars and pads back the same amount as the saddle if going for KOPS, so thought I’d ask if it’s worth doing as my position would be the same, just further back.
Suppose it comes down what produces the best power whilst keeping it relatively comfy.
Got a race coming up soon, so think I’ll leave it where it all is which is around 1-2cm further forward
If your knee is about 1 to 2cm in front of your pedal spindle, I would think that your position on the bike is fairly poor.
If you post a video of you riding on a trainer, there are some pro fitters on here who could make some recommendations on how to improve your position.
