This is illusion. If you go from 400 to 440, what will wind actually see is addition of 2cm in the middle of the bar on each side which is thin and aero optimized. It is not that there is 4cm "more" bar in the wind lol. So if you run wind tunnel test for 380 vs 440 without rider, you cant even mesure 1w difference. Second thing is with rider. GCN did mesure 14W difference, but their measurement protocol is failed. You need to shorten the stem/reach by 2-4cm and add up to 4cm of stack to get the same position(same hip, torso, neck/head angle) and get proper shoulder-elbow-wrist-hoods aligement on the wide bars vs on the narrow bars.Lina wrote: ↑Mon May 01, 2023 8:58 pmEven if you have no rider on the bike wide bars aren't as aero. Between 36 cm and 44 cm bars there's 8 more cm of bar in the wind. Sure the difference without a rider won't be massive but it is there. Now throw a rider on top of the bike and you can see the difference without even a wind tunnel.Minirac wrote: ↑Mon May 01, 2023 8:31 pmIndeed, there is zero/0w difference if you set up wide bars correct.
Yes, the added frontal area from the extra bar width is marginal at best. But it does increase the frontal area of a bike.Minirac wrote: ↑Wed May 03, 2023 3:06 pmThis is illusion.

When you're measuring different bar widths you shouldn't make the positions exactly the same. Especially if the goal is to be aero. At least my natural position with narrow bars is completely different than with wide bars. The right way to measure isn't to make the exact same position with both bars. The correct way to measure is to have both bars how you'd have them in real life, even if that results in different position on the bike.
No no no no! In-accurate. Then you could just lower your stem with any bar and get different position. YOU have only ONE ideal dynamic pedaling body position (for lets say a road bike) - hip, torso, neck/head angle - that is defined by cranck length/stance width and saddle height/tilt. You can however then manipulate shoulder-elbow-wrist geometry and aligement by different handlebar shapes. But your ideal pedaling dynamic part (hip, torso, neck/head angle) should stay the same!Lina wrote: ↑Wed May 03, 2023 3:25 pmYes, the added frontal area from the extra bar width is marginal at best.

This blog needs better moderation. This handlebar stuff is so ridiculous

what needs moderating ? Not a single spy photo of anything but a box. You can't have rumors when nobody has a clue other than the new handlebar that'll likely be included. How about a rumor on what absurd price Specialized will charge for the frame only and complete builds ?mrbrown4001 wrote: ↑Wed May 03, 2023 6:27 pmThis blog needs better moderation.

Because it's off topic. They can create a separate thread for handlebr talk. It has nothing related to the SL8. It's annoying to see new comments in a thread about the SL8, then get here and it's more pointless bickering about a different topic.skinnybex wrote: ↑Wed May 03, 2023 8:21 pmwhat needs moderating ?

I disagree, I think the handlebar situation is one of the only things that even matters about the stupid thing.LanceLegstrong wrote: ↑Wed May 03, 2023 8:45 pmBecause it's off topic.

I didn't check but I do believe all this handlebar talk started because the new handlebar is pretty much the only thing we know about the SL8. And there is a well known issue of limited sizing available in integrated bars. So it's not surprising everyone is talking about literally the one thing we know about the SL8.LanceLegstrong wrote: ↑Wed May 03, 2023 8:45 pmBecause it's off topic.

Lol, you have a single picture of a bike box and the roval bars. My rumor say's the Sworks frameset will be $6,000 for Frame, fork and seatpost.LanceLegstrong wrote: ↑Wed May 03, 2023 8:45 pmBecause it's off topic.
