Time Trial / Time Trialling / TT

Different diam. bung?

This. Extensions are 22.2mm OD, most bars (everything but Vision) are 23.8mm.

All the cool kids are using tall towers between base bar and elbow pads for the aeros, but I tend to bang on about it for the better handling.

Yeah, the Vision Metron stuff. I thought it basically was available(ish).

Shifter on the left, brake lever on the right ^^^

Maybe I was dreaming then and all the versions I've seen have been DIY/bodged extension brakes.

What's better handling about them? Lower when cornering? I'd expect the pads might get a bit whippy - I've seen some people make braces up between pads.

No, there are definitely brake levers which fit on your extensions (any MTB/flat bar, plus some specific TT supplementary levers)
Jtek (also sold by HED):

FSA/Vision:

and there are levers which plug in to the end of 22.2mm bars too, DiaCompe make a thin version of the 188 for town bikes.

Yes, the base bar hold is more like riding on the drops rather than on the hoods.

How high are your pads from the base bar? Do they feel solid?

I'd expect the pads might get a bit whippy - I've seen some people make braces up between pads.

Depends how tall your stacks are and how you ride. I pull on the tribars quite hard climbing on 100" fixed, and my 60mm 3T stacks are fine. TriRig suggest putting a bridge across (their BTA bottle mount) for spacer stacks over 35mm. Fibrelyte make Pro Missile stacks up to 100mm, but they make a cross brace too, so I'm guessing people using the really tall stacks have felt the need to join the two sides.

I usually use the 3T bridge in front of my Garmin mount, as the first generation Ventus has a tendency to rotate the extensions about the vertical axis, but I've ridden without it and not had any trouble.

They're all too ugly to consider.. and that's saying something given I ride a Tri bike!

Ah, it was the Fibre Lyte site where I saw the braced PRO. I remember now.

Mine will only be ~20mm and the Spesh bars are pretty solid (save for their pad holders but I'll forgive them for thinking we all ride on Californian roads..)

I want one...

Yes, the base bar hold is more like riding on the drops rather than on the hoods.

Personally I think I'd prefer to have my base bar in a position analogous to my hoods, but then I use the base bar for (a) comfort (occasionally sitting up on long rides... I obviously need better adaptation) and (b) on climbs which are less likely to be an important consideration in TTs.

Check out this guy for all sorts of tarty carbon mods.

Hmm, much of his stuff looks remarkably similar to the Alden Designs carbon stuff.

Yeah, I've had their page up on my phone for months now. Not really sure what I want or need, other than it needs to be faster less slow!

Would be simpler to just buy a Meccano™ set

I had a Jtek lever many years ago - front or back brake it was sketchy as f*ck actually trying to use it at race speed/in race mode

Star Trek?

We need fly-by-wire braking so a light button push knocks down the speed.

Think I'll aim for the Mersey Roads 24 in 2016 (already a clash for 2015). Should be a nice warm up to any slvlss stupidity later in the year, and it's been on my list of things to do for a long time.

500 looks like a good target based on people I've ridden with before.

km that is. Miles is for fa[s]t people.

[EDIT] Unsupported, or at least I wouldn't say no to any support from any AUK lot that tend to lurk around.

It's good fun. #LOL=LiesOutLoud

Think Ishmael did >480mi unsupported when he took 3rd place a couple of years ago.
