I’m looking to extend my aerobars by a few inches. Currently using a 2020 speed concept with the monobar fork extension.
I can find cheap extenders, typically for MTB, on Amazon but I can’t find anything that supports a Di2 cable. I can vaguely recall seeing someone offering a 3d printed version that would suit but my googlefu is coming up short.
Any ideas? Basically just trying to lengthen this:
Thanks!
Thanks - I’ve seen those and thought about that as part of my solution. In my mind, I probably have 3 solutions* that could exist
1 - cheap extensions (do these exist?) - $50-$100?
2 - Plug in version, plus reach adapter (they only have 3 bolts vs the 4 bolt that I have), plus bars and would likely require a shop to bend them for me. Probably $500-600? ($250 for the bar plus, $150 for the reach extenders, plus extra for the bars)
3- Custom front end. Probably TriRig ultimate scoops + an adapter plate and hardware to match my current position. Probably the most aero but… $1500-2000.
Trying to see if I can knock off a cheaper solution before I go more expensive. And if I’m going to spend $500+, I might as well just go for the most optimal solution anyway.
*The 4th solution is just to cut my base bar in half (cut off the grip part) and bolt on some ultimate scoops to the wing I have, but I suspect this is neither aero nor safe
With black friday sales from TriRig and this adapter from FastTT, you can probably go option 3 for closer to $1000. The Scoops Ultimate might get you as much reach as you need without any additional reach adapters, but you could always get these or these to add a few cm.
Ooh, I hadn’t thought of that and I haven’t seen that plate adapter before.
I’d still need to figure out adding height and angle against the scoops - which adds a bit of cost. Angle seems easy since TriRig parts look like they stack, but I probably would need to add stack somewhere.
But something to think about if they go on sale and/or if option #1 doesn’t exist
Thanks!
Just bumping again in case anyone knows of a solution for this which isn’t redoing my front end. With the black Friday sales, I might well redo the front end, but checking to see if if there’s a cheaper option before I go spend money
I am not following what you mean by number 1? You need number 2 (the mono plug in) to run any round extension on the SC gen 2.
What do you mean by supporting di2 wiring? Are you using the older 2 button tt shifters where the cable is routed externally? Most extensions have a slot cut open near the tip to route the cable inside the extension.
For #2, what do you mean by bending the bars? You don’t need any fancy bars. You could easily pick up some used carbon extensions or even some cheap aluminum ones.
I’m basically looking to extend the tops of the current bar by a few inches. Right now I’m running TriRig scoops but with an additional angle relative to what the Speed Concept can do. On the picture below, I’m basically grabbing air and would benefit from a few more inches of aerobar. I can find cheapo options on Amazon which add a few inches to the aerobar, but I’d need a hole through the centre to run the Di2 wiring.
For option #2 - Because I’m looking for more angle than the SC will give me, I’d need to marry whatever bars I’m running with where my hand lands virtually. Though at this point, I might as well just replace the whole front end since I’m halfway there on cost.
Is the pad wing mounted on the 4th hole (furthest reach)? Have you slid the mono extension all the way forward? How is the pad oriented (are the pads more forward than where the pad wing mounts to the mono extension)? There are 2 different ways to mount the pad wing and one adds reach but reduces relative extension length. The other way does the opposite.
If you have a picture of your front end looking down on it… that would be helpful.
Wing is mounted to the furthest hole, the mono extension is as far as it can go for both reach and tilt, and the wings are positioned in the forward position. I’m as far forward as I can get on all settings, except for one bolt on the pad (pads can come forward one more spacing).
If you know of any other solutions, I’m all ears - thanks!
Do you have the ergo short or long extensions?
If you have the long, I’m out of ideas with the current setup. I tell most people to go with the mono plug in (I ran it for several years). The mounting holes on the extensions are spaced 22.5mm apart (had to go back and look my notes to find this). So if you use the 3rd mounting hole on the mono plug in and move your cups/pads one slot forward, you could make up for most of the reach. You would be short by 2.5mm.
Personally, I’m not a fan of any of the aftermarket solutions. I can understand the desire to want to use the ultimate sl scoops (I run them on my gen 3 sc and they are fantastic) but I’m not sure how you would run them on a gen 2. You would have to get a plate that covers the mono risers and has the ability to mount the scoops with your desired positions (width, height, and reach). If you go aftermarket, you typically end up spending A LOT more… ask me how i know 
I’m on the long extensions, so I guess I’m out of options.
The drawback on the plug-in is that I’m then at the absolute end of both stack and reach that’s available, and I’d need to redo the front-end if I wanted to gain either. I could buy some wingspan extenders. which would buy me some reach, but now I’m dumping money into it anyway…
For the front end, be looking at the previous edition of the Ultimate Scoops, as they’re on sale this week. I haven’t quite sold myself, but short of a $50 solution that I started this thread looking for, I’m kinda out of options.
If you are on the edge of being maxed out both stack and reach, I’d be seriously considering sizing up a frame. At least to give you better flexibility for any adjustments down the road.
Wish I had a better solution for you.
Not just frame, but also wheels as well, as my race wheels are caliper brake and anything new is bound to be disc brake
Yeah the rim brake to disc brake switch is a tough one to swallow. I went through it a few years ago. I would be hesitant to spend any significant money on your current setup if you think you might get a new disc brake bike in the near future.
I see it almost the other way. For a smaller sum, I can extend the life of this bike (and wheels) for another 5-10 years. By that time, hopefully the industry has been responded to the need for more reach that we’re starting to see now.
Plus, I might actually be able to reuse whatever front end I end up buying vs the stock solution from the new bike
Send me a PM, I might have something for you.
(Less than $50)
That’s fair. But I question your 5-10 year estimate. Spare parts for these bikes aren’t going to be around for another 5-10 years. The bb90 bearings, rd hanger, and seat post clamp are specifically for the gen 2 sc. They could be hard to find in a year or 2. The bearings/bb are a known issue and the saddle clamp is known for corrosion. Any of the front end components are proprietary and won’t always be available. I had to warranty a fork a while back because one of the threaded inserts stripped where it attaches to the stem.

Good point. I hadn’t thought of end of life wear and tear. More to consider. Thanks!
