What did you have prior to the P Series?

I donāt have that. Maybe post a pic and I can post a comparison pic. Mine is a 2024 model, fresh from the factory in May.
I did a test run, 6 out and backs. Really good correlation of data but MAN IT SUCKED. So before posting numbers I need to get to the bottom of it. I suspect the factory installed tires are really bad. Also, I didnāt have a guage so used what the shop put in and they were hard as rock. If this is it, I will quantify ābadā. I think this would be important to a newbie.
Thank you

2.5x the CRR of a set of Corsa Pro Speeds. The Zaffiro is an OE spec placeholder. Cervelo used to put fast but fragile tyres on so the first (or test) rides felt good. But all price driven now (note your microshift levers).
an extra watt of resistance in the 105 rear mech bushings
a couple of watts on the chain assuming you hadnāt stripped it yet
Plenty of really low hanging fruit. Showing newbies how much benefit there is from collecting that fruit would be helpful.

2.5x ? Holy tire tragedy batman !
I rode again yesterday and got very consistent SLOW numbers. I am glad to see the tires are probably a big component and I need to quantify it.
I was concerned that it may be the expansion of the A in my CDA
I wonāt be able to get any type of PSeries/Scott comparison until I settle on tires. Given thatās something most need to do anyway, I guess that is worth spending some time getting to the bottom of and quantifying.

As long as the tires on all the bikes are identical, it really shouldnāt matter what they are, no?
Since Iām old and retired, I ride a lot. Fast tires wear out too quickly - there is just too little rubber on them - my reason for training on Continental Ultra Sports and Vittoria Rubinos (but I do put latex tubes in them). It also helps slow me down a bit, so itās more equal to the youngsters I ride with!!

Absolutely. I was just surprised by how slow these tires were. Tests will be done with 5000TTs
I also put these little suckers to control tire pressure variability. Again I was shocked by the delta between my Parktool pump guage and the values I was getting here.
If I was on hookless Iād be scared for my life

The ālittle suckerā can obviously read tire pressure. Can it also lower it?

No, but when you CRR test it is really convenient. You start at 90PSI, test, drop a bit, test, drop a bitā¦no pumps or other gauges involved.
The amount of error introduced by pumps is non negligeable.

My parktool pump said 60PSI. These little suckers said 72.5. So if I would have used my pump to 72.5, this little suckers would have been at 87 ?

Funny, you quoted and highlighted something that disappeared from my post. It was meant as a jokeā¦
I figured as muchā¦

Your P series has this or not?

The LBS did not install the Bento, for which this seems to be for. I placed it by hand and it is pretty tight to the steerer tube and doesnāt seem like it would ācatch airā
Itās a separate piece from the bento and probably serves two purposes. 1) to cover the rear brake hose going into the frame, and 2) to make a smooth transition from the stem to the bento. I cut mine back a bit so it doesnāt stick out as much.
There are a couple ways to cause what youāre seeing
- tightening the bolt too much so the rubber splays
- pushing it too far forward
- permanently distorting the rubber (usually by doing one of the above for too long)
Iād start by loosening the bolts, then looking at moving it back a little and not tightening the bolts too much afterwards

When it comes to a Plasma 3 as fast as possible the colour is important. Is it grey, yellow, or green Ć¢ā¬Ā¦? We have a yellow one and a green one on the start line, soon to be tested which one is faster.

I know they yellow one had some things for full internal cabling that the grey didnāt. There was a hole in the steerer tube to route cable internally. I had the grey one drilled by the Argon carbon engineer so I could do the full internal cabling.
