I have now got used to my bar extensions after a few months. Couldn't spend long in them at first but now am on them most of the time.  Not modern aero versions but will relieve any prolonged hand pressure which is main concern.

Not doing PBP, but have got my bars sorted for TCR:


if that's your preferred shape, there are profile jammer gt extentions that look neater and would be lighter too

before people get carried away - the discussion here is not whether tribars work or not (they do), but how to set them up in a pbp-compliant way and whether it's worth it (it depends).

Yeah, there's bars out there that are close to the right shape, But considering I got these for €20 (including the bar tape!), and added €10 bar ends, It's hard to beat on price. Not sure it's worth worrying about the few grams I'd save in terms of weight, Also the setup I have now works well for strapping a bag too.

Maybe when I have another job, I'll experiment, but for now, these work for me. I'm loving having the di2 shifter on the uprights. Being able to shift from the aero position is amazing! They would be PBP compliant if I was to cut about 15mm off the end of the horizontal too...

Bullhorns might allow you to use longer extensions (or not cut them down as much).

Shifters are less of a problem if you're using Di2 (or fixed). I didn't mind losing the drops as I rarely used them, much prefer aerobars for headwinds.

Compare these two for example and see how the aerobars don't stick out as far past the brake levers with bullhorns:

was playing around and testing different options today:

found a comfy setup that works, only the levers have to be opened forward (alternatively - a longer stem):


The rules say "Handlebars extensions are allowed only if they can't extend beyond a line created between the front of the brake levers, which must not be pointed forward."

Probably a good thing because my 2 foot long brake levers were a bit of a hazard.

The "must not be pointed forward" part doesn't appear in the French rules.

I had almost given up on the idea of using aero bars for the PBP because I couldn’t stay on them long without lower back and hip pain. It was also difficult to mount my lights as they need to be the right way up and would normally go in the same place the arm rests have to go. With the Mersey 24 hour TT coming up I decided to make a few changes to my bike including flipping the stem to raise the handlebars about three inches and then refitting the aero bars. I tested the new set up on Sunday on an easy DIY 200km and found it made a huge difference. I could stay on the aero bars almost all the time without any discomfort and the kilometres flew by with little effort. I’d only just recovered from illness and been off the bike for two weeks yet did my fastest ever 200km!
The bars are full length so too long for PBP but after the Mersey 24 I’ll fit some short ones that happen to be the same diameter into the same arm rests. As for the front lights, I have zip tied and taped them to the side of each aero bar so their beams are directed nicely onto the road ahead. I’m planning to test the new setup including lights at the weekend with another DIY 200km ahead of the 24 hour the following weekend.

all drop bar levers point forward if they are set up correctly, the question is how much forward is still usable/rideable.

bullhorns are an option, but i like riding on the drop part and use it often. one other option would be to use long reach drop handlebars, but i can't stand the shape to actually use them.

I think the intention is that you cannot provide a placement for your hands which is further forward than provided by the brake hoods. They have picture of “within the rules” tribars on Facebook. If people start pushing the boundaries officials could become pedantic. My tri bars don’t extend beyond the brakes but they are capable of doing so if I adjusted them. They therefore might break the rules depending  on how you interpret “puissent”

Standard mounting for modern STIs has them pretty much vertical. Mine point backwards because they're set to minimum reach.

it's one of the uncomfortable shapes of the bars i was talking about earlier, with long ramps sloping down. with ergonomic handlebars brake levers are slightly forward (at least when set up the way i like it)

It's worth thinking how you might modify your handlebar setup if you get Shermer's neck. I'm a bit concerned that riders are trying to limit the strain on their backs. The shock absorption given by the back, when arms are not locked out, will be transferred to the neck muscles.

Here's an article where a RAAM rider turned his aero bars through 90 degrees, and the problems with that.

I have stayed out of this discussion as I am not a tri-bar user. Most of the people who I have ridden with who use them are not aware that they weave around and make close group riding impossible. There are some exceptions who can ride in a straight line, but that is not common in my experience. If you must use these then please use them after the large groups have thinned out.

Inspired by this thread. Two cheap aerobars used - some modifications still needed but mainly ok. I added bolt to keep arm pads in right position and don't have to tighten too much.
