86mm wheel set
 

How are the wheels still performing I am getting ready to purchase a set of these...any issues of concerns?

Side wind?

Go for it and report back to us.

Too deep for general purpose use.

This thread is too deep for regular use.

Are we missing a page?

Still have love for the deep rollers. They don't sell nearly as often as they used to back in the day. Personally I have a set on my track bike because...well....I can, they look great, and I'm fat so I don't get pushed around.

I'm in flat Houston and am a high watt heavy rider and I run 81 Vision Metrons about half the rides I do.

I have 50 mm and wouldn't want anything more, if I was buying another set I'd get 38's.

There is a noticeable difference on the deep 81mm wheels vs wheels in the 45mm to 55mm range at speeds above 25mph or when alone or out front 22 or above.

I have over year of speed and the wattage data. I know there are other factors but my sample group using two depth wheels on the same bike with the same set up is about 2000 miles on the same rides. It's about an average 12 watt difference at the same average speed for me on my bike.

To heavy, too much to control.

Did you measure the HR difference between the two?
Note you didn't say which took less power.

My testing I found the deeper took more effort (reflected in HR) for the same power. Meaning there was core effort that was higher for the larger profile wheels. Time and time again, chose to use 50mm profiles.

I just re read my post.

To clear a few things up:

I have 2000 miles per wheel on the same bike or 4000 total. I have a stable of bikes and another 10k of miles on different wheel sets since fitting power meters to my bike stable. But when I chose to look at the difference objectively I had to use the bike that I switch wheels with. That being said I notice the same thing on my other bikes but the wheels stay put.

There is a watt difference of 12 watts advantage at a given speed. So less power to go the same speed or the same power to go faster.

My heart rate is directly related to effort or cadence. If it's a low watt effort my heart rate is cadence related. If it's a higher watt effort it's power related. I had no difference in heart rate between the two wheel sets on the same bike.

That being said I'm sure if I used the deeper wheels in Texas hill country I would prefer the shallower wheels. But 90% of my riding is done in flat Houston or the surrounding area that's flat and windy.

I think my riding location, fitness, size and speed greatly favor deep wheels.

It's 210 gram difference from my 55 Metrons SL's to my 81 SL's running the same tube, tire and cassette combo. I only feel that weight when starting from a light at very hard effort during a club ride. At speed the deeper wheels feel quicker. I have yet to have any control issues with the wheels.
