20km flat TT circuit.
29th March - Training wheels, aero helmet, skinsuit, cervelo P3C TT bike. 30:55 with 230W average power.
10th May - Zipp 303 tubular front, training rear wheel, regular helmet, skinsuit, cervelo R3 road bike on the drops. 31:02 with 280W average power.
Let's not speculate how slow I would've went if I pushed 230W
Nice lift in power. Why not speculate? Should also take into account the impact of variable conditions.
I did same sort of comparison here:
Nice work Ant despite the aero difference.
I was there today too, my very first time trial and I did it on the only bike I have (Giant OCR). I did take off my bell and saddle bag for the ride though Also, TroyC (on the forum) lent me some boot covers for my shoes which added a few extra kph TroyC did well pulling out a 27:47 (43.2kph) and I managed a 30:43 (39.1kph) which I'm very happy with. I didn't know what to expect but I was shooting for between 38 and 40kph.

Because there's no need to say how slow I used to be on a road bike
Race report writeup states same temp on both occasions. Very calm conditions today, was windier in March (reported gusting to 30kph), not sure how that'd impact. Maybe I would've gone a few seconds faster, which would've exacerbated what I just posted a little bit more.
I read your blog (I actually read all your blog writeups). Your comparison >> my comparison.
So I guess in summary: time triallers getting OCD about their gear is very justifiable
But didn't you hurt yourself very recently when you trashed your TT bike?...you are up and running quickly or am I getting confused?.
Are we going to see a power file .
And didn't Tyler Hamilton break his collarbone in the first stage of the '03 Tour de France and go on to get 4th overall?
Emergency department suspected a fractured wrist along with a cracked vertebrae. Got the green light pretty quickly with the back, and after getting a CT scan, the radiologist and one orthopaedic surgeon said I had broken my wrist, after looking at my CT scan. They both made rookie errors according to a much more emminent surgeon Just badly sprained. Back is a little bit stiff but is pretty much fine; getting heaps better every day, and my wrist is sore, but not too bad. Not too bad for crashing at 70kph
Besides running over potholes and other bits of bad road (hurts), I can't grab my water bottle because I can't ride 1 handed using my sore wrist, and I can't yank it out of the bottle cage with my sore wrist.
Nice time mate.
Dimitri did better Says he was having an 'off day' too
Hooked enough to make appearances during the winter ATTA series?
OK...i thought you were still pretty beat up...so weekly HTFU awards is yours for this week .
On the aero side of things...huge jump in power...do you think enviro-mental differences made a difference..as your times are very close,but your av wattage isn't.I knew a TT set up saved energy but 50w seems a bit much?.
That's a fitness increase - no doubt about it. My times would not nearly have been as close if I was on my road bike back then, or if I was on my TT bike now.
When talking about time trialling, being aero doesn't really "save" energy, it allows you go to faster for the same energy. What I mean, is using a set of aero wheels will save you watts sure (especially in wind-tunnel speak), but that's just assuming you're going at the same speed, ie, it allows you to ride at that same speed for lesser watts, but we're dealing with the inverse of that - it allows you to travel faster at the same watts. Threshold watts are threshold watts. Does that make sense? I'm not great at explaining things at times.
Last Time in March I had a pair of 10 year old Cosmic ally Clinchers,
Today I had a brand new pair of Prolight 90s with 19mm Corsa Tyres
and went 3 sec slower...........

Now is that because you almost slipped over in the wet and subsequently lost your rhythm?
depends. if it's an out and back, then overall wind usually adds time. but in some circumstances it can also lower your effective CdA.
Anybody has some bike position tips for me?
I have TIME rxr time trial bike, aero helmet, full suit and shoe covers.
But i think i'm too low on my bike and loosing power.
When i did bavarian championship last weekend i felt like having inert moving legs, as they were inable to give full capacity.
IÂ´m sure it werenÂ´t the wheels
Just applying these assumptions:
Using a heavier and less aero training bike with identical measurements and fit as your full aero and lighter race bike, surely you would be faster. Same watts/power, less drag/wind resistance. Is that safe to assume? It sure feels that way!
All else being equal, then if a frame is more aero and lighter, it will result in a higher speed. Maybe not a lot higher but higher nonetheless.
