They flex though! I started getting paranoid one had cracked it was moving so much, but can’t see anything. Guess that’s just a difference of carbon fibre compared to metal.
The foam also took a bit of getting used to when you spend longer periods on the extensions. When your arm sweats, the material doesn’t really allow that moisture to go anywhere. And initially it wasn’t that nice a feeling. But quite quickly got used to it.
Being higher sided, you have to be a bit more deliberate putting your arms into them, but that quickly became fairly natural and automatic.
Useful to know. I heard a creak at one point after hitting a bump on the road, and then seemed to simultaneously become more aware of flex in the left arm rest, but I can’t see anything that says it is compromised.
As you say, and as I suspected, its likely just the nature of carbon fibre
Oh that is crap. Straight back to them & money back! What torque did you use, out of interest? I always use about 4nm plus loctite on this sort of stuff.
I have popped my chain waxing cherry. Daughter is now using my wife’s road bike on zwift, which she doesn’t use after a scary spill because of an incident with a car. It’s been in storage and needed a new chain, it was fairly straightforward TBH.
Replacements received. Raced with them yesterday. They were comfy. Yet they cracked again. Exactly the same place on the left arm rest. The photos almost look identical. No idea if it’s something to do with my setup, and having to use the inner attachment holes based on my fit, but they are clearly not fit for purpose for me. Used the bare minimum of torque this time, simply to stop them rotating.
I have contacted aerocoach with a view to returning for a refund.
I can’t recommend the ones above enough. I think leahnp said they are more robust and I’ve pushed them a bit sat with my hands on the pads and they barely flex at all. I can’t imagine them cracking without some real force.
I just had these arrive. Only £65, but they’re aluminium. 18g heavier per arm rest compared to my original ones, if I use the little bolt recess plate. Only 8g heavier if I just accepted the bolt head pooing through the foam like you have to with aerocoach. I’ll accept the minor weight penalty if I can get the same feel as the aerocoach ones, which I really found comfortable, but the durability of metal!
Very generous! Would have given them a stab if I hadn’t just bought the other ones.
The only thing that’s a bit weird with these aerolab ones is that the foam is not velcro attachment, it’s direct stickiback. I can’t see how that’s going to work for trial and error on positioning, and travel. As I can’t imagine it’s multiuse
