Aero Road Handlebars + Clip-On Aero Extensions

Searched TR forum but couldn’t find anything…

Any suggestions for an aero handlebar that supports/fits clip-on aerobars? :man_shrugging:


Selcof used to sell an aero drop bar & separate tri-bar extension kit.

They still sell the bar & it has the threaded openings to put the aero extensions on…but I don’t think Selcof sell the aero extensions sepearate from a time trial base bar anymore:

Here is their time trial cockpit:


Bontrager Elite Aero Handlebars, the carbon fiber XXX Aero is also compatible with clip-on aerobars. I have the Alu on my bike with the RedShift Sports Quick Release Aerobars.

The Profile Design DRV/AEROa (man, what a name) is an Alu aero handlebar that’s clip-on compatible.

I’m trying to find confirmation, my recollection is that the carbon fiber 3T Aeronova supports clip-on bars… but the Alu ‘Pro’ model should be fine.


The Giant SLR works with their own clip on aerobars, on the pricey side for sure.

There are also a handful of stem mount options that should work with almost any handlebar. Like the discontinued lightening strike -

I have the same question. Looking for something that will clip on to the S-Work Aerofly’s on my Venge, anyone have any suggestions?

Clip on bars for road aerobars are typically customized by the road bar manufacturers as far as I am aware of.

The venge vias handlebar has its own propriety clip on bars:

Enve have their own for their ses aerobar:

I went ahead and purchased the selcof aero dropbar/tribar extension combo mentioned in the above post. My plan is to put it on the gravel bike I’d also like to try it on the NK1K for those stage races that have a mini TT as an introductory stage…that way I could set up for the TT & then take the aerobars off, move the seat back, and use the same bike for the crit & RR.

Do you know of any stem mounted options that still exist? Can’t seem to find the Lightning Stryke anywhere.

First of all, I don’t have any connection to PlanetX & Selcof other than I have purchased these handlebars & extensions for my gravel bike.

Second of all, PlanteX just put the drop bar/aero extension combo on sale fo 99 pounds. Cable (GBPUSD) is 1.3 right now so you’re looking at about $130 for the whole thing. That’s a pretty good price for just the drop bars. And, sadly, I just paid $80 more for them!

Hi @Brennus, are you still liking your setup? So you purchased both items you provided the links to above? Do you have a photo of your set up on your gravel bike?
I can’t find the matching stem.
I am thinking without the matching stem there would be huge gaps with most stems and the selcof aero drops bars?
I am looking for an aero style drop bar as well that can be paired with aerobars for the occassional triathlon.
Thanks very much

Still got the same setup on my gravel bike unchanged! When I race I stretch some of that rubberized tape over the gap between the tops and the stem…what do they call it? Flex tape? Anyhow, that’s not as much of a kluge as it might sound. It looks pretty clean & is probably more aero than just leaving the stem exposed.

The handiest part of the setup is the ease with which the aeros can be taken on and off. Many, many times if the group ride is going over what I know will be rough roads I’ll just take the aeros off, put the 28mm tires on, and take the gravel bike road riding. It really adds a new dimension to the bike.

I’ve messed around with skinny tires and the selcof aeros vs my full blown TT bike on a couple of loops. I’m outdoors so it’s hard to say for sure but I’m guessing the TT bike is something like 5% to 8% faster same effort, same course, same conditions. So if I can do 25 miles in an hour on my tri bike I’d probably be 3, 4, 5 minutes slower on my gravel bike with aeros…but still way faster than just my gavel bike on the drops.

I have another pair of the handlebars that I plan to install on my road bike so I can take just the road bike to stage races with a time trial. The performance gap between my road bike with the Selcof’s and my TT bike is probably much, much smaller. And I’m willing to sacrifice a few seconds if it means I don’t have to pfaff around with a 2nd bike on the road.

Is it S-Works shallow carbon handlebar compatibile with clip-on aerobars? (Deda alu)?

I’m looking for an aero road bar (flat, wing shaped tops) that’s also compatible with some clip on tri bars.
I’m giving my old road bike some love, gonna upgrade the 7900 to R8000 and a few other bits, and I’d like some aero bars, for looks mostly, but I also want to be able to throw on the tri bars for the local TT, and, as usual, I don’t want to break the bank.

Does anyone have any recommendations for this very specific set of criteria?

There’s a few. Only one that immediately springs to mind is the 3T aeronova

I’ve been using the selcof drop bars with integrated threaded holes for aerobar posts on my gravel bike for a good little while now. Solid, cheap, aero. And it allows me to ride fairly aggressive drops but a fairly sky high aerobar pos’n.

I don’t know if this falls into your definition of “won’t break the bank” but Enve sells clip ons that are compatible with their aero drop bars.

Vision Metron 4D…has dedicated mounts for Vision aerobars.


Sounds interesting. What model are you running?

I use Giant’s Contact SLR bars. They make clip ons designed to go specifically for them. So a great set there!

And the clip on attachments:


I have these and whilst there is enough space for clip ons, I’m loath to fit them though as IIRC the clamping force for a set of clip ons was higher than the recommended setting for the stem.
