Here is a couple of these, that I am looking at myself:


Swiss Side: Can a wheel manufacturer be trusted to do aero apparel?

Zoot: This looks like a new model... ?

Fusion: Magnus/Daniel/Laidlow are not even using these...

Compress Sport: Are these the Laidlow sleeves? Isnt he in socks?

This may (or may not) be obvious but HUUB's naming of these sleeves references the time the Skipper TTT (major HUUB team contingent in wheels #1-#7) took for 180km at the Sub7 challenge, riding the distance faster than anyone has ever done; and possibly ever will.

Difficult to trust that an aero sleeve has any benefit, when riding last in a 6 man train :) But HUUB has some pedigree in aero indeed

Swissside or Huub.

Swissside has built their own, smaller wind tunnel for fabrics / small parts. This allows for prototyping and multiple iterations testing. My colleague, who works at Swissside as an aero engineer, speaks highly of the new calf sleeves.

Huub has a well-known aero pedigree, not only thanks to Dan Bigham. Sub-7 was just a great testing environment. I personally use both the Huub Anemoi suit and the aero calf sleeves (if they don't work, then worst case they at least protect me from sunburn).

There's actual testing on them. You don't have to try to compare one company's marketing to another.

Yes - I have seen this video, and it´s good, but 1) it´s 2023 and 2) its not taking more than 3 products into consideration...

Yeah that's fair. I don't anticipate much of the physics has changed since last year, and the the fundamentals remain the same. No wrinkles but don't stretch them out so much that the ribs flatten. My take home is find the ones that fit properly first (I know, that's the hard part) and then of that subset buy the ones with the deepest ribs.

I tested those HUUB sleeves on several people already this year. Mixed bag. Slower than others for some and bare legs, faster for others.

The answer to are they faster, at least based on what I've seen this year from my testing, is it depends, still.

I've raced in the Rule 28's, Zoot, and Swiss Side calf sleeves. No clue how they test, but I find the Swiss Side's to be the best fitting. They have the most coverage and are just tight enough across my entire calf. The Zoot's and Rule 28's pinched the top of my calf a bit too much, and were too wide near the ankle. Fitment alone the Swiss Side's have been my favorite.
