Roka Sleeved swim skin reports?
Quote | Reply
Apologies if there is topics on this already, I've searched and come up with nothing.

Has anyone tried one of these? I am looking to order one when they become available again but I am yet to read any reports and havent even seen a picture of anyone wearing one..

Very interested in some real life experiences with sleeved tri suits under them.

i have one and like it. i've now done 3 races in it and it worked well; which is to say, i didn't notice it.
on the sleeves underneath: i haven't tried that, so can't report.

50/50 for me. I have it and have tested it in the pool. It is faster than without. The fit is not very good for me. I have a larger upper body in the chest and shoulders and I get pinching under the arms. If it fit a little better I would be much happier. It fits everywhere else. Over all I think it is fast.

Can you explain your protocol a little more that you did to test

Not very scientific but did 5 x 100 with suit and 5 x 100 without. I was 3-5 seconds faster with the suit. Only used RPE to grade effort. Not like with a bike and power meter which can be used to make sure effort is the same when comparing speed.

I did a race this weekend out of town and I forgot my swim skin. Which I had it.

For the Roka I like it technically just which it fit "me" better.

very non scientific here: I swam faster in kona this yr with sleeves then i did last yr without sleeves on what felt like much less effort. Did not even notice the sleeves. Full disclose: i am not a swimmer and don't pretend to be.

What is your hundred time. Can I suggest some thing if you have time. Do a 4x800 at this same RPE. I don't care which one you start with but would like to see A B A B or A BB A. Curious what the results are.

Thomas what are you trying to point out?

That the suit is no faster than wearing a tri suit with nothing over?
Or
That the suit is no faster than a non sleeved suit with a sleeved tri suit under?

Probably that the testing doesn't alllow you to determine if the suit is better and by how much in a predictable manner.

I agree and stated that it was pretty unscientific. I already own it so will wear it in my next race in February. It's not wetsuit legal. The hydrophobic fabrics are faster. There is a reason that the IOC and FINA banned them from competition. How much for the avg swimmer can be debated.

better than what though? sorry I was just trying to work out if he was saying its no faster than wearing a tri suit only, or wearing a sleeved tri suit under a swim skin with the arms sticking out.

Anyways Ive placed an order on one today as they are now available again. From those who have them the reports sound positive enough.

Thanks

I totally agree with Thomas. If anything, I would reverse the order and start withOUT the suit. This way, even with fatigue after the first 5 setting in, you would see possibly a slight improvement even if you're starting to feel tanked. Mixing it up would be a lot of changes because you'd be trying to put on a wet material every other 100, where you may or may not work all the wrinkles out & the material will not be in the exact same place as when you originally put it on. Therefore, all things are not really the same with the back & forth switching. Rest time will vary as well.

Worse, that it is slower, than wearing a tight fitting tri suit.

Sorry, I didn't see this until it got bumped today. I am interested in more data. I know for myself they are slow. I didn't test the Roka, but I tested a Kiwami and it was just awful. For me a slightly older, trisuit, front zip with two rear pockets and a neck line I could feel water buzzing over, was consistently faster over cruise 800s than a both a swimskin (BS) and the Kiwami Aquarush. I have since tested sleeveless trisuits more afterward and I found an even faster suit than my test suit, that was a Kiwami Amphib rear zip. I have a lot of thoughts on this. I need to do a post, I have been talking about needing to do a post for 9 months... I guess I was hoping to see some sort of testing whitepaper produced from somebody showing what thought actually went into this all

And keep in mind the last time I did testing myself was many many moons ago with the neoprene swimskins which were fast fast fast. I simply never tested swimskins after the ban because I was basing my decision on others.

Interesting.

I wear scody and even the sleeves sticking out feels slower but maybe it's in my head. I've never really tested or considered testing.

I tested a sleeved trisuit in there as well. It was with the sleeved trisuit that I saw some benefit from wearing a swimskin, but everything was slower than just my trisuit albeit they are tight fitting which I think is also key. But I have a whole theory on sleeved suits in general after going back to the wind tunnel for a second trip. I'll have to explain that theory as well in a post but the skinny is I am still not convinced that in a practical application of sleeved suits they are faster for the masses. If you are Sebastian Kienle and you are wearing essentially a brand new suit all the time maybe it works, or if you are dry and you put it on, but if you are wet and/or it is used and stretched, ripped in minor places that you might not even notice, or maybe the fibers haven't gotten just a little too rough the benefit could go out the window. If you are using the UV that is one thing, but pure speed, well I am not convinced for triathlon.
