I put this on mine: https://www.amazon.com/gp/product/B00ATH0KEA

Works really well.

I have some grip tape I am meaning to apply to see if that helps.

Doge

For a specific TT (Valley of the Sun) on road bikes (and how collegiate TTs work I found out) junior would have his TT sleeves and about the time of spraying on number glue, we'd spray some 77 on the bar tops. Turned out lots of racers were also putting tape forearm rest/padding there, and refs allowed it (as the rules were vague), so we went to the tape on top for that event and didn't use glue any longer.

But need to add - glue number to aero list.

hack

Based on perceived gains or measureable gains? I'll go back and check, but I thought specialized did a wind tunnel test and found really good vs really bad number pinning yielded minimal benefits at best?

Ygduf

9 seconds over 40k using 4 pins vs using 8 pins. They say it like it's not a lot, but 9 seconds is a lot, and they were using 8 pins and not glue. Glue probably 11s vs 4 pins. Glue vs. 8 pins, probably "not a lot".

This has been my hold up as well. I've intentionally avoided 11s because I had too many 10s cassettes and freehubs. But I really want eTap, so I'm willing to suck it up a bit.

But over the last year, I was able to upgrade two wheelsets to 11s freehubs - in one case, I found a great deal on a used CK R45 11s upgrade kit, and in the other, I cracked my rear Zipp, so I needed to replace it anyway. That got two of my three wheelsets to 11s. The last wheelset is a 240 hub, and those are pretty cheap/easy to upgrade.

Also, when I say I'll be going 11s, what I really mean is that one of my bikes will be 11s and the other will still be 10. I cannot afford to put eTap on both. Not to mention that my wife is already running 11s on one bike and 10 on the other, so we will still have two 10s bikes in use. So I'll probably keep them 10s until I wear out all my cassettes or win the lottery. Whichever comes first.

Gotcha ... was thinking gains from better pinning/gluing for Matt (and myself) would be limited since time spent solo in the wind is pretty small.

Could I bother you to post a pic of your bars? I like this idea.

Ygduf

in that scale it is very small. in the scale of relative to other stuff doge is posting (wider brake pad gap) it's astronomically large.

dz_nuzz

Not the best angle perhaps, but I think you get the idea:

DSC_0002.jpg

I trimmed the tape to follow the contours of the bar.

mattm

Yes.

But what I'm getting at is: are aero bars really doing anything special, if mounted on my Tarmac? (the cables have to come out of the bars, and go back in to the frame)

I didn't see any Win Tunnel testing around this, hopefully they do it soon. I'm sure the result would be "buy the Vias", but I don't want to.

hack

"Buy the VIAS, but wait until we fix the detaching rear triangle."

Doge

Glued "correctly" I think it should be the no-number range.

But what is NO PINS?

topflightpro

Yes, aerobars help. How much, that depends.

But as someone else said on some other forum or discussion - if those bars are saving you three watts, and those three watts are the difference between being under threshold vs. over threshold, then they are totally worth it.

mattm

I'd like to see wind tunnel testing of that though (full aero bike like Vias vs aero bars w/ internal cable routing vs classic bars w/ internal cable routing).

They are flatter from the front, yes - but has anyone proven that saves even 1 watt?

Doge

Brandon went with a few of the changes (Brakes) on his own last week. But if he hadn't I bet he'd only have won by 25 sec instead of 35.
Daniel beat him for 1st in the VOS TT two years ago by 1.6 sec. That pretty much solidified that adding up the little crazy sounding things - matter. Of course a drink of water or a couple backward glances could have done that too.

But yea, in going aero start with the frame and parts.

This is an earlier (better ones someplace in the hotRnot thread) - before re-wrapping tape and some more trimming, but you can see the air channels open brakes allow. Also later shrink wrap tubing over Di2 cable and brake cable for one item hitting wind rather than 2. The segmented cables allow positioning in front of the head tube. We played a lot with where to tuck the Di2 junction box and just went the normal place, but it would fit in the stem - just no adjustment. His coach got the look 795 so we had a little aero competition going.

dz_nuzz and the rest of the aerobros on the team love reminding me of how not aero my tarmac is haha. 44cm round bars with thick tape is not clean or aero. There have been some really great deals popping up on the facebook online swap meet group, a few aeroflys and some zipps, I would have swooped down on them but #freelancerlife

Thank you very much. I am going to try this.

I generally avoid expensive handlebars because they're the first to touch the ground. that, mixed with carbon, is not a good deal for me. 3T aeronova makes an aluminum version, but they're like $200+. For Aero equipment, all I have is a helmet (which I use sparingly) and skinsuit.

basically, my personal lessons:
I used to have wheels, but got tired of changing brake pads, and the braking surface sucked
used to have aero frame, but the cost/benefit wasn't worth it for me
thought about handlebars, but they scratch easily in a crash. they typically have longer reach that would necessitate change in stem as well. the good ones are super expensive. too much trouble

skinsuit is pretty good value for aero
helmet is imo pretty good value, because even when I do crash, the helmet is rarely affected.

no input on internally routed cables. I don't worry about it, so I have a regular cannondale, and I don't think it holds me back

Maybe a TriRig front brake to go with an aero bar. That will clean up the front end quite a bit.

hack

and etap

Ygduf

tririg and other front brakes are ~3 seconds over a 40k effort. not worth it.

just reporting in - I put some baseball bat grip tape on my aero bars for IAB and while I am not practiced at the position, it did feel a million times more secure when not slipping all over the place and I'm sort of a believer now. Definitely something I will try to add to my break efforts.

Hermes

Road one piece jersey / bib short combination. I have one and like it a lot. It has a couple of pockets in the back and totally unzips from the front if it is really hot. The material is more breathable than a skin suit.

scheibo

I'm a huge fan of Castelli's Velocissimo as a one piece option - super comfortable and fast. I also got it like 50% off, but I'd probably pay full price for it.

Re: grip tape - tempting, but it would ruin the design on my bars!

Ygduf

it's known as the san remo, and it's great when it's not falling apart. Runs large though in sizing relative to the rest of castelli
