I have a 2015 Trek SC 7.0. I’m thinking of upgrading to the Speed Concept Mono extension/spacers aerobars. The cost is $900 to do this. Anyone care to chime in how you like the monextension/spacers on your Trek SC. All the 7.5s come with it. It looks a lot more aero than the standard aerobars that I have. But are we talking less than a minute time savings in an Ironman?
It’s going to be closer to 90s over an 180k bike ride for the Mono extension.
There are much cheaper options (and more adjustable options) than $900 that get you within 20-30s over an IM.
Let me say this: it’s super nice, rock solid, and I highly doubt there’s a faster aerobar out there. The tilt adjustability is pretty money too. If you look at the Alphamantis thread on extension tilt, ~15degrees of tilt could be worth ~10 watts (you need to field test to be sure).
If they just changed the front brake and made the base bar grips to match the new 3T Revo Trek would have the perfect front end.
I doubt even a minute IMO. The bars are super marginal gains as most can supply the fit you need to pick up the most low hanging fruit. I’d have a hard time spending $900 on them if it was me.

I would put at way more than a minute, the aero bar that comes with the 7.0 is a super basic round (not even aero) cross section. You are probably looking at closer to one minute for a 40K. I would guess over 100 grams of drag difference, hell the difference between the vuka aluinmum and the trek bar is 60 grams.
Now granted there are other bars that would come closer to the bontrager bars for much less than 900, especially used.
**…hell the difference between the vuka aluinmum and the trek bar is 60 watts. **
If you say so.
Are hou getting $900 from retail for bsrs only, or does include the new cabling too? You will have to redo your whole front end, I think.
On another note, you should be able to get the front end in 2 pieces from ebay for total of 250, I would bet. Look around.

I think he missed the pink with that statement

Damn, grams, 50 grams.
At $900 you would be better off selling your 7.0 and buying a 7.5.
My 7.5 is my first tri bike so take this with a grain of salt, but I really like the front end. It looks good and is comfortable. My biggest complaint though is once you go to the mono bar you limit your choices of BTA Hydration setups if you use those. I also get some clicking in mine. I took it apart, greased a few parts and torqued all the bolts; it went away and came back within a few rides.
All that being said I’d have a hard time spending $900 and I think the other poster that said selling your bike and getting a 7.5 would make more sense. Definitely try to find the parts used.
I also get some clicking in mine.
Are you positive the clicking isn’t coming from your brake cable housing rattling inside the bars. My wife’s SC does the inside the bar rattle thing that drives me crazy while riding with her but luckily she doesn’t notice it.
YMMV,

I think “super marginal” is an exaggeration. Check out the data here http://forum.slowtwitch.com/forum/Slowtwitch_Forums_C1/Triathlon_Forum_F1/Fastest_aero_road_bar_(under_$200)_and_expected_time_savings_P5252530/
That said, the OP is in a bit of a pickle. Lots of cheaper bars would gain a bit of time, but if he springs for the speed concept upgrade then he gets the fully integrated front end.

These tests have been done by a number of sites. I see 30-76 grams of drag between best and worst when looking at average weighted chart in your link. Throw out the cheap Zipp bar and the delta is around 2-30 grams. To me that’s marginal.
Well, except for that the OP’s bar is most likely worse than the alumina. http://www.220triathlon.com/news/images/75C_7435-Edit.jpg
Probably more in line with the syntace set in the old cervelo test that was 80-100 grams slower than the best bars.

The biggest single equipment change I ever did was switching from a Profile Cobra T2+ to a HED Corsair. I was faster overnight. A lot faster. Bigger than any wheel, helmet, or frame change. Almost the same position, only I did bring in my elbows about 1 cm each. Same stack/reach measured at the pads.
But since then I’ve always thought that bars are the single most important piece of equipment in TT. More than frame or wheels.

There is something about the Speed Concept front end. I just love it. Totally feels rock solid and soaks up bumps. When I had a Gen 1 SC I questioned whether I would like it but it totally blew me away.
So what would be a good alternate if I don’t want to spend the $900 on the sc aero bars?
