Correct. You can also find the company that did it in the photos
I had my road and tri bike fit there as well (same company, different branch). I liked their approach and the results felt good (tri bike position is still work in progress).
I think TT/Tri position is always work in progress.
The cycle of adjust position ā learn position ā get stronger in position ā adjust positionā¦
Is pretty much endless.
Many WT pros still have bike fittings semi-annually.
Iāve been working on finding a compromise with being aero and comfortable with my new front end setup before I go to the wind tunnel in two weeks. I recently did a decent 100 miles non stop ride without much discomfort with the below setup. At the tunnel, I plan to test the Met drone, Poc Tempor, Giro Aerohead, and maybe a Kask Mistral. I also have a Velotec, No pinz, and Castelli suit to test. I have a 3
Spoke wheel that was recently shipped but I donāt believe I will have it in time to compare to my 80mm front happier wheel Of course I will have my disc wheel on the rear.
Additional fit suggestions or tips are much appreciated.
Any guesses on what CDA I can achieve at 172cm and 68kg?
Love the bike. I had it prior to having our first kid, then sold it.
Iām impressed you held that position for 100 miles. It doesnāt ālookā comfortable. But it clearly is as you held it for so long
Iām assuming your rest up for TT and not triathlon? You are pretty far back on the saddle.
Thanks and Yes, I only race TTās with this bike. I have the saddle nose 5cm behind the BB to get further reach on the front end. In those photos the front extensions are angled slightly above the legal limit although I will try them at 15 degrees in the tunnel to compare.
My first advice always is:
Bike fit first:
Get stable on the bike. I donāt mean big changes, but how is foot pressure, how is saddle pressure, does your hip rotate, do your shoulders tension up too much?
I am sure your position is pretty good already, but even world tour pros do that regularly.
Now that your position is nice and stable, a velodrome aero test is the best to see if your position is fast. So how fast is your position really, and how can that be adjusted.
Lastly, do a wind tunnel test to see if your gear is fast. So what helmet is faster, what skin suit is faster, what Hand position is faster etc.
Thatās my general advice, might not apply in your specific case.
Your position looks really good already.
Of course that is the correct and methodical approach. Unfortunately in my area itās not an option for velodrome testing that Iām aware of and the wind tunnel option was an opportunity I could not turn down.
Hoping I can reach a CDA number close to your 0.198!
Iād be surprised if you didnāt get lower than that. Your position looks really good, and at 172cm, you can definitely get to sub 0.19.
Oh, I think youāll hit that easily with at least one of your helmet options, possibly all of them. Would be surprised to see it even lower.
Position looks fantastic
A new front wheel arrived⦠looks like I will get a chance to test it against a 80mm deep 25mm wide spokes wheel!
Are you going to tunnel test or test on the road?
Both!
Nice! Look forward to seeing the results!
Looking forward to hearing the sound.

Earlier this week I had an opportunity to spend some time in the tunnel with an emphasis on dialing in a UCI legal position. Ultimately my baseline (Giro AH helmet and NP P1 Suit) CDA was .196. With some adjustments, we lowered it to .187. Swapping helmets, suits, and wheels around resulted in a best CDA of .186 (Tempor and NP P1 suit)
Some takeaways with watts at 30mph
Velotec Dynamic / +2 watts and +5 watts at yaw vs NP P1
Castelli body paint suit / +12w and +10w at yaw vs NP P1
Met Drone WB / +17w vs Tempor
Giro Selector / +12w vs Tempor
Giro AH / +2w vs Tempor
Kask Mistral / +9w vs Tempor
UCI illegal high hands position was very similar at 0 degrees but my yaw CDA dropped -4 watts.
The 3 spoke light bicycle wheel vs 80mm spoke wheel was about 3w slower at 0 degrees and -7.5 degrees.
The Giro AH was the most consistent helmet for me and will be my go to if itās windy and/or a course Iām not familiar with.
Dude, your second pic is awesome. You look like quadzilla! Love it!
Fantastic positionā¦.it is ugly as hell, but I love the way a Tempor helmet fits against some riders shoulders / backs.
