Now this I don't understand!

Yesterday I went for my first cycle in a month and struggled throughout the short duration that I was cycling. Today I upped my mileage and my average speed was also a lot better. What I don't understand is that yesterday I was using deep sectioned rims by Mavic. Today I was using the stock DT Axis wheels which are significantly heavier than the Mavic wheels. The ride quality felt different today, and I felt like I had more control over my bike.

Are deep section rims overrated? Or do they just take the time getting use to?

If this trend continues, I'll be looking to purchase some higher quality low profile rims.

Brakes rubbing?

Definitely not. I always check before that there is no brake rub. Maybe I was just incredibly rusty yesterday being the first ride back, but the deeper profile wheels definitely felt more difficult to handle and for some reason, caused more lateral movement of the bike when out of the saddle.

Not sure whether spoke count has anything to do with it?

Different tyres/tubes/pressures? Just the effect of needing yesterday's ride to remind the body what's involved after a month off?

Yes, different tyres. Using Mavic Yksion powerlink tyres on the Mavic wheels and the tyre pressure is about 110psi. Quite a bit lower on the other wheels too. Not sure whether anyone has any experience using these tyres or the turbo's by specialized. A few friends I cycle with use the turbos and have nothing bad to say about them.

Apparently slicks take time to wear in - anyone confirm this or is this false?

some tires take a few miles to wear in as they have a coating on to aid popping them out the mould during manufacture. This only take a few miles. Also as the tire ages the the rubber starts to break down which can make them grip a little better.

I'm currently using the Turbo's on my winter bike, 5000 miles in on one set and got my first puncture last week. They still have a few more weeks wear left. They aren't particularly supple but I rate them as a high mileage training tire.

As for the wheels, personally I'd wait a couple of weeks then ride both sets back to back and see what you think as bike always feels a little strange after some time off. The side to side movement out the saddle could be due to the gyroscopic forces of the deep section wheel having most of its mass at the rim as opposed to a more balanced wheel on the DT's. Another thing could be that when you are out the saddle you steer slightly to maintain balance, the deep sections may be less responsive to this passive steering motion as they have a much harder time pushing through the air flowing around the rim.

This would be the sensible thing to do. People buy deep section rims because they like how they look. People buy low profile rims because they are the most effective tool for the job.

I'll definitely have to agree with you at this moment in time. I was met with a much stronger headwind today, yet again I found it significantly easier to battle through it than the light headwind I dealt with yesterday. How much of an aero advantage do aero wheels actually provide?

I'll be using them later so I'll continue to give more feedback then, but first impressions are not so good. I'll see what Ugo has in store ;-)

Much less benefit than an aero helmet and skin suit! but a perfect excuse to message ugo, infact he is building me a deep rear wheel and wide low profile front, tarty and practical!

Ugo yesterday was the strongest up the climbs, even with his 11 kg bike, what should we make of that?
Another day another path of discovery...

Used them last night and they felt fine, but not amazing. Would say the stock wheels are more forgiving when hitting small potholes and other variations in the terrain

Good then, one for the Sales section of the forum...

+1 re aero suit etc. I got some deep section wheels for TTs, result 6seconds improvement. Started using a skin suit and aero helmet, result 44s improvement.
