I have some room to move arm rests closer together like an inch on my bike. Is it going to help with any aero gains? I have Profile Design arm rests and I have to buy something like Tririg arm rests with more holes to make it happen. My aero extensions are already close to each other, so I want to keep them where they are. I have a set up like this.
These will allow more adjustments.
Please let me know if it’s worth investing.
If you have Tririg arm rests, are they comfortable? My Profile Design arm rests are pretty comfortable.
Thanks in advance.
I believe narrow is faster for most. It makes shrugging more comfortable for me. Shrugging and turtling will me you faster.
If you can already shrug and turtle then you are probably most of the way there.
Put a mirror in front of the bike a look at your frontal area with your elbows an inch closer. That should give a pretty good indication of the aero impact.
it depends - sorry there is not an easy answer to this without some form of testing. You might narrow and get your shrug on, or you might narrow and pop your head up. And possibly either would be better/worse.

Isn’t aero fun.
I want to try it out, but it’s $87.50 including shipping for a pair of Tririg arm rests.

Ok, thanks. Let me set up my trainer and try this.
I just picked up a pair of TriRig armcups and they’re fantastic. I much prefer the material of them to the traditional more fabric like foam of profile design. I’m coming from some very decent vision ones as well. You won’t regret buying them.
It is possible to go too narrow, and narrower setups will create arm/shoulder fatigue for some. A good rule-of-thumb is to have the spacing set so that your upper arms are in the center of your quads (helping to shield them).

I didn’t know about this. This is a great information. Thanks!

Good to know!! Thanks for your feedback on them. I was curious how they feel.
Narrow is not always faster…it tends to be but not always…just the same as going lower.
Keep in mind fatigue, BTA placement, and how it can affect your head position.
Lastly, how do you plan to test it out and confirm? The arm cups arent expensive, but figuring out if they helped can be…If you arent prepared to confirm this, then just stick with what you got
I drilled the holes and now they are about half inch closer to each other. I feel more locked in and secure this way.
I hope you are just doing that as a temporary test. Because I don’t like that modification AT ALL, from a structural safety point of view. WAAAAAY too much opportunity for stress failure.
That’s a good way to find out how good your helmet is.

I suspect that is a minor consideration looking at the minuscule amount of drafting you’d get. And add a little yaw…
If you are closing off the gap between your arms with your head and hands, that seems like a it’d be winner. But if the gap is there then making it a bit smaller won’t necessarily help. The effect on shoulder posture is probably a bigger consideration.

I dont quite see it like that.
I’d defo make sure there are no nicks / notches and smooth everything, but otherwise the weakest cross section is unchanged - as there has been no metal removed from the ‘line’ that runs front to back through the centre line of bolt holes. Also with moving the pad inwards there is less bending moment on it (it is less cantilevered outwards).
I can only go as narrow as my arms about middle of thigh. I have wide broad swimmer shoulders and it hurts after 15-20 mins when they are too narrow. Comfort over a 100 mile bike will usually benefit me for than a few % in aero gain
