There are basebars that you could use your same extensions combo's that will save you 2-4w over the Zipp Vuka basebar.

Think thin

Gains from new clipons or basebar will be very minor. Two items you might want to look at:

1. Get a BTA cage and bottle to fill in the gap behind you hands.



2. Get an aero bento to clean up the airflow behind the stem/steerer.

I just replaced my vuka bull base bar after near 8 years of service and while I found a few downsides with the bar I am not sure I would be quick to replace them. The biggest potential aero issue with the Vuka is often cable routing, but you have managed to make it look incredibly clean. I did find that the brake cables tended to wear out quickly due to the tight bend required to cable through the bar. A related issue is the bar ends which very narrow so you will never be able to maximize the bar using your current brake levers.

I ended up replacing the bar because it cracked at the junction of base bar and brake levers which might also be a function of the thin narrow nature of the bar ends. The cracking was more likely due to overtightening the brake levers and using the bike on a static trainer (where the bars are put under higher stress), but is happened underneath where you currently have bar tape. I was a bit lucky to catch the cracking early on when I was re-taping the bars as the bar would have likely have failed in a catastrophic manner on the road if it was continued to be used.

 On the older bikes bentos are almost a shoo in to be faster. On the newer bikes, flip of the coin...at best.
On the other side of that coin though, you need to storage. (shrugs shoulders..what are you going to do?)

Agreed. If the stem is already aero (see below), little to be gained. If (like the OP) you have a standard stem and steerer/spacers (typically lower end or older bikes) then there is def. a benefit.

I would wait at least until there's some data from the MorfTech bar. If it's definitively faster then you'll want to at least consider it.

Dragging up the dead here-

What base bar would you recommend? Eyeing Vuka Bull or Profile Svet R.

thanks much.
