Individual and Team TT
Looking at doing the Calga TT probably every month for at least the first few months of next year. So I wanted to get some Aerobars. Can anyone advise some good but also cheap bars. I would be looking at <$150 and preferably <$100.
Clip ons ok ??

The price is right, can't comment on the quality though.
These are pretty good (for the price). I've seen them elsewhere for as low as $75 delivered (so shop around). The advantage on these is that you can set them back from the drop bars (toward your body) if you wish.

They are good bars as you can adjust them a lot but are therefore a bit finicky. I have the carbon version of them. Make sure you when you adjust them you use the right torque to tighten, when I setup might I didn't have a torque wrench so was too cautious and one of them started to loosen while on a TT. You do end up putting a fair bit of weight/pressure on them.
torque settings very important, also use carbon grip paste at the junction faces
The bicycle is a curious vehicle. Its passenger is its engine.

Sorry to bring up an old thread. I am after some aero bars for an aero road bike (Venge). I am mainly after something with a fair bit of adjustability and specifically something that can accommodate the lowest possible position. On an older bike I do a fair bit of riding just resting my lower arms on the top of the standard road bars and then grabbing the shifter cables for stability and I like that position. New bike does not have gear cables to grab, so I want some aero bars that can give me the stability, but get me as close to resting my arms on the bar tops as possible. Thinking of giving a TT race a go, but not wanting to get a TT bike just yet.
Appreciate any suggestions! Those torpedo 7 bars above seem to be pretty low with the bars going under the road bar?
Thanks in advance.

Compact and safer than long jousting poles.
Get an adjustable stem for when you want to run aero bars... it is the only way to drop the bars far enough that your elbow pads sit around the same height as your bars normally would.
Only fit on 27.0 mm handlebars. You'll have to fabricate your own clamp to get them to fit modern handlebars.
I've already looked into this. Have bought a new pair from Planet-X...now have to manufacture new clamps.
Another option is if you have flat-top handlebars you can just rest your forearms on the handlebar tops and run bare extensions.
I'm doing the bike leg of a half ironman, and I've borrowed some aero bars for the event.
I can't be bothered getting a proper fit as I will be taking the bars off straight after the event.
What's the general rule of thumb for positioning adjustments when throwing on some aero bars?
Move saddle forward (as much as possible?), drop stem, and lower the saddle?
I know I will end up making adjustments as I go, but it would be good to have a decent idea on the base.
Slide saddle forward as far as it will go. Drop the stem a bit. Move seat UP about 4-5mm.
Sliding the seat forward shortens the distance from the pedals to the seat.
26.0mm. But yes, you are correct. I'm still living in the 90's and keep forgetting about this "oversize" fad.
I ended up getting Profile T2+. However they are a gift so will not receive them for a month. Just reading the last few posts here. I run a seat height of 725mm. If setting up for TT position, should I shove the saddle all the way forward and adjust height to match my normal 725mm? Will than keep all the angles the same for my fitting? Then just adjust the Aero bars for comfort? I read an article somewhere that suggested that people commonly have the aerobars too far forward, and the angle at the elbow should not be too much more than 90 degrees so you can efficiently take your body weigh onto the Aero bar pads?
You can run the saddle as far forward as 5cm behind the BB. I do this, I have an Adamo saddle, so can sit quite comfortably on the nose area. Basically re-measure your saddle height to where you sit on it in TT position, as this can make quite a difference if sitting much further forward than on a road bike. You can run it a bit higher than normal if you want... beware of injuries though.
After that the aim is basically to get the forearms and back parallel to the ground... ie getting the head out of the wind. Take a bit of playing around, don't try and go to low, just find what works. Depending on how you have your bar / stem set up will depend on what can be done. You really need to drop your bars and 2 to 4 cms if you can so that your arm rests will be sitting at the same height your bars were at least. Hence maybe needing an adjustable stem. Just sticking aero attachments straight on to you road bars with out dropping them means your head is still sitting up pretty high.
Also with those bars make sure you have a torque wrench and some carbon paste... they have a habit of rotating ( especially armpads ) if not cranked up well.
I'm waiting on a set of Profile T2+ aero bars for my road bike, which is going to be a time trial bike for a couple of seasons. I rarely use the drops, and if I'm going to lower the stem to get the fit as suggested here, I probably never will again. What I'm wondering is whether I can cut the drops off and plug the bars just below the brakes, or is this prohibited under some UCI/safety/modification rule?
That rule only applies to UCI (and local affiliate) sanctioned events. For triathlon it's still pretty much anything goes.
Why not just get a bullhorn bar then?
I had a thought, but it got run over as it crossed my mind.
Chopped the bars and ended up with what I thought was a nice looking setup. Unfortunately it probably falls foul of the 'no modifications' UCI rules so ended up getting a bullhorn bar anyway along with a set of bar end brake levers and bar end shifters for the extensions.
Putting in time on the rollers now to get used to steering and shifting in the aero position and to practice moving from bullhorns to aerobars and back without wandering off line. Three weeks to my first Calga doesn't seem like a lot of time to get it sorted but we'll see how things turn out on the day.

The UCI rule changed this year. You may automatically have peak of saddle no further forward than vertical line through centre of BB (but if you do then the extensions are limited to 75cm in front of BB). Alternatively if extension go beyond 75cm (but by no more than 80cm) then peak of saddle must be 5cm behind BB. No morph checks anymore.
There are most definitely triathlon bike rules and they differ depending on the event and governing body. It's not a free for all.
For example, ITU competitions (e.g. Olympic styles events) uses UCI bike regulations as follows:
For Triathlon Australia (IM type events), the rule on peak of saddle is no more than 5cm in front or 15cm behind BB. There are a detailed set of bike set up rules for TA:

You may not modify equipment in such a manner if it's a UCI event. Equipment used has to be as supplied by the manufacturer.
