10W is huge.

I do need to learn to shrug. As I said earlier I moved the pads closer and increased reach (which will have to get changed back to become UCI legal). This lead to less fatique with shrugging.

However, I there is a huge difference in my shoulder width when I am shrugging vs. relaxed. I am at least a few inches wider.

47.0kmh would be awesome.

my goal is to always get my shoulders as narrow as my rib cage. :) given a 41-42" chest, this is easy :)

so that bar would set me back almost as much as a Giro aerohead. I wonder how many watts it is worth. I know you would not know this. Just thinking aloud.

I have a stack of them. I need at least one for a future project, but I can probably part with one cheap to further your cause.

Sent you a pm. Looks like there is a used market for these bars on e-bay as well.

Might be a worth while upgrade.

There are 10 watts available on your front end. You might only get 6-8 on the cheaper upgrades keeping the 31.8, but I'd call it worth it.

The Syntace is the most aero 31.8 base bar, except the ultra narrow 3T. You might want to consider that as well. Make sure you take a look at the cable routing on some of those 3T bars though, sometimes they screwed it up very badly.

TriRig brake. Just do it. It's worth it at twice the price for a bike that has brake bosses.

3T levers.

The tri rig is a great upgrade. But...

The shipping to Canada from Tri-rig is insane. So I am keeping my eyes out on a used one.

Do you have data to back this up?

Were I the OP I'd be looking for Tulas.

I do.

Not identical, setup but close.

TRP front brake center pull, Profile prosvet bar, profile levers, adjustable stem to Ventus and a Tririg brake. Suplicy Quantum

So you tested against the Tula, HED Black Dog, et al.?

Don't you use an Alpha X setup?

No.

Opps.


Do you believe the money would be well spent on the front end of my Transition? You do a ton of testing, will it make that much of a difference?

Yes and no. If you can source Tulas (narrower the better)/Alphas/PRO Missile Evos cheap (easiest with the Tula), then yeah you'll save a few watts with no real effort. If you have to pay retail then you're almost at the cost of aero testing, so not sure I'd bother in that case.

Best bet is to spend time Chung testing with aerolab. There are a few services out there that will help you with protocol and collate the data properly for a small fee (AeroCoach being one, but there are couple others; I'll have to check if they're still trading).

Found this. Interesting. Apparently from Cervelo testing.

Tula yes, Black Dog, no. Have never tested any of the 3 HED bars. I built a bar similar to the Tula that tests better, and has brake levers that work better as well.

Tula often requires an adjustable stem since the extensions always mount inline. Stems and round clamping are the worst for Aero.

I will put it this way: I own a lot of Ventus, and sold the Tulas. Ventus II is my favorite bar, as it also can be used with Magura brakes which I love.

Ventus II is fantastic, but alas has too much stack.

Interesting thoughts on then clamping, as I've found that different bars and stem combinations have different interactions (and some integrated systems are just horrendous even though they look slick).

Yeah, the Tulas tend to work best for those who need a low stack (moving to Enves on the T4 for this reason). From a braking standpoint, my front is instantaneous (as strong as any of my road bikes) even with super dodgy routing, and the rear is fine (tbh I don't think I've used my rear brake this year, plus I shaved the pads the wrong way so likely not a good barometer).

Be interested to see the bars you built.

How can you mount a tririg brake effectively if you aren't using the tririg stem, won't the cable be awkward? I'd like to get the tririg brake but worry about the cable routing.

There will be a gain there but unless he's already done some major positional work, it's not as high up the list of prioritys. Helmet, skinsuit (and both worked in together with positional work) will likely yield him the lowest hanging fruit. There are always gains to be had. Look at it this way, I'm 6ft 3, 90kg, well built and after several visits to aerocoach have recently made some radical changes to get myself down to a sub 0.2 CdA.

That is an incredible CdA for your height and weight. Got a picture you could share of what that position looks like?

I haven't.....purely as it's a new position only achieved last week. However, to give you some backstory, I played in the wind tunnel 6 years ago. I started out at a mid 0.24 and we eventually got it down to a very long 0.22. I stayed like that for a few years and dabbled in pseudo superman positions and other stuff (as I don't tt under uci rules). A year ago I went to see aerocoach for velodrome based testing. You can't compare cda's from different methods but we got me down from a 0.23 down to a short 0.22. Since then I lost 6kg in weight, changed my skin suit and replaced my wheels and tyres. When I got remeasured a fortnight ago I was down to a mid 0.21. I went there wanting to do some experimentation based upon some ideas I got at the uci age group worlds in the tt. The outcome of that drove things sub 0.20. In fact, I had a couple of runs at 0.196 and 0.198. The key idea was that I'd spent years trying to get the air through me (as is often the way for larger riders) but I played around with getting the air to go round me since helmets and suits have changed and allowed this to work.

From one "big" guy to another (6'2", 80kg), I'm submitting another vote for pics and descriptions of your setup! Doesn't have to be perfect, just give us a sneak peak.
