I have an 8 mile hilly TT coming up. No TT bike. Have deep wheels, shoe covers, skinsuit, TT helmet, and aero roadbars (PRO carbon version). Figure I have 2 options on how to tackle it.

1. Leave aero roadbars on and ride IAB position the best I can.
2. Swap out for my round bars and add on clip-on aerobars.

Thought?

If its a real hill just go with 1. If its rollers clip on aerobars all day. You'll probably have to move your seat as far forward as you can.

Do you race? Have you ridden a TT?


@TMonk - I'm actually not slippery. I'm average at sea-level TTs. It's no coincidence that the one result I have that's good, at nationals, came at the sweet spot elevation where you gain more speed from thin air than you lose from reduced-oxygen FTP.
I have Profile Design's Airstryke mounted to the OEM round bars. Clip-on tri-bars came before drop aero bars but many have never considered them. Some believe tri-bars have been the biggest change in biking in 20 years... going back to when Greg Lemond won the 1989 Tour de France on the final day's TT. I'd suggest them to anyone with enough interest in aerodynamics to consider drop aerobars, even if they are not racers or in a TT. I'll admit that starting with or only going with changing out round bars for drop aero bars is a lot easier than learning to incorporate the use of tri-bars into your cycling.

Clip-on aero bars are not allowed in mass start road races, which was the original premise of this thread.

Good point... I now see the situation where someone would be looking at improving aerodynamics and yet be willing to settle for sleeker handlebars.

Yes, hence the whole "aero road bars" craze where they are otherwise normal drop bars except they have a flat, low profile top section. The improvements are incremental and minute, but taken all together with an aero helmet, skinsuit, wheels it makes noticeable difference versus a regular road bike setup.

I know because my preferred setup for routine training is a Giant TCR and regular jersey/bibs, and normal lightweight helmet. When I get decked out with the above (mass start race legal) stuff I'm definetely faster on a hot lap at Fiesta Island (~4 mi).

I own a FELT DA2 my kid TTs (and wife rides) on. I have it setup for a front end change only from traditional TT bar extensions to an aero road bar - Specialized Aerofly (??) mass start legal bike. I have pictures if needed. So same bike. The mass start legal bike has the bars quite a bit higher than a road bike.

The rider setup is the same from a hip/back. Riding the mass start legal drop bar bike with forearms on the tops is just about as fast and the full TT setup. It is more sketchy. The extensions on the TT setup are used to pry on and the shifter buttons are easier accessed.

Similar setup on the road bike is quite a bit slower because the bars are lower/slammed and the idea is you hold the bars with your hands. The forearm on bar tops is too low and constricts.

I'm in agreement the body is the most important. For a TT - everything matters as placings are often separated by 1 sec or so and most have the big stuff taken care of, so the things like bar shape, helmet, skin suit, elbow position and aero bike might determine which step you are on.

I cut about 2-3 cm off the ends of the drops, making it pretty clear where I put my hands. Looking at the bottom picture, if I cut off the straight section of the "before" bars off, I end up under the stem. With the Bontragers I'm well forward of the tops, basically where the black electrical tape site.
I did my first real ride today on those, and can definitely see what you mean. however, i can see myself getting used to it. it kind of forces me to lower my upper body in a sprint, which is advantageous for aerodynamics. perhaps the handlebar is too low and not stretched enough. will have to check the side pic to be sure.

Dunno, but I once clocked a sub-56 minute 40k on a Giant TCR (size M) with clip on aerobars and a Giro TT helmet on about 310w output.

My new bike came with an Aero road handlebar (Giant Contact SLR). It's a 42 CM but it measures 42.5 CM at the brake hoods. My old bike has a 42 CM bar that measures 42, for some reason the new bar feels way wider than .5 CM.

I was thinking of going with a 40 CM bar anyway. The Zipp SL-70 is $200 on Ebay but I am worried about getting a counterfeit bar. The Giant contact SLR bar is a little cheaper and it will match my bike but I think the Zipp is a better bar.

Or is it not even worth changing it for 2 CM?

How wide is the bar at the drops?

A lot of aerobars flare out. So a 40cm bar measures 42 at the drops.

I just got 38mm Zipp SL-70s and it is, indeed, a very nice bar. Mine was 238 grams, but feels pretty stiff. Far, far more stiff than my 3t Aeronovas. Although the shape isn't as nice as the aeronovas, the reach and drop is a bit better suited for me. They're pretty much at opposite ends of each other.

Hmm, I have zipp sl-70 38 and aeronava 40cm, and haven't really noticed a difference in stiffness.

related topic: USAC added a new rule pertaining to aero mass-start road bars:


1I1(d) Additions to the handlebars (shapes, pads, etc.) other than standard tapes and wraps, that encourage forearm support, are not allowed in massed start events.


I asked the head ref at my last race how they intended to determine what a "pad" is, and he said, "if I poke it with a ballpoint pen, and a dimple remains, I'll consider it an illegal pad." I also asked him if something like skateboard grip tape would be legal and he said he would interpret the rule to mean that grip tape is legal.

Really? I can't see how. The aeronovas are the flexiest bars I've ever touched. Just standing there and I can push the hoods or drops down with one hand.

Pretty much the consensus from anyone else I've ever heard that had them.

I wish @Doge was still around to pitch in his thoughts on this. He got me started even thinking about this and now he is an official and i feel he would have good input on it.

how about you don't put pads on your aero handlebars?

the answer on enforcement will be like everything else: it depends. some will be strict, some will not care, you will not know until you line up.

I don't put pads on my road bars. I did just recently re wrap all the way to my stem though, because my forearms were getting sore from IAB on the flat tops. And now it's warm, so they were also slippery when wet.

Err NM. I have aerotundo team. I think I wanted to go with aeronova, and it got stuck in my head.

also note, likely not enforced until nationals. nobody (probably...) really cares at the local level, unless they're looking to be d*ckish.

when I went to nationals they didn't check bikes or enforce anything.

At Masters Track Nationals last year, they had a jig to check bikes.
