I’m specifically interested in knowing if anyone has had issues with the disc rubbing against the duotrap bulge in the chainstay. Also if there are any clearance issues around the brakes and fork/frame and what max tire size you are able to use.
HED customer support will neither confirm nor deny that they are compatible.
Take the duotrap out and put on the plastic cover. No risk of clearance issues. Do you really need the duotrap sensor for what I’m assuming is just for racing?
Oh, I don’t have a duotrap sensor. Just the bulge for it sticks out a bit from the chainstay. I have a disc cover on the stock wheel and the clearance is pretty minimal so it seems possible that there could be issues with a disc wheel like HED’s (lenticular spoked wheel with permanent cover) depending on its exact shape.
I have the HED jet black 60 front and rear disc combo on my 2014 gen 2 speed concept. No issues with fit. I bought mine sometime in 2018 but I don’t thing anything changed since.
Thanks. Yeah, I’ve read about lots of people with various prior HED models on Speed Concepts, but I just worry that something about them changed with this newest iteration. The width at the brake track is still 25mm though which seems to be compatible with the Speed Concept.
Clearance on the seed fin is fairly tight and the 21 mm internal width will make the tire a bit fatter. I can still get a GP5000 28 in there, but anything wider would probably require trimming the inside of the fin or using the UCI-legal cover.
A few years ago I bought a 2017 medium SC off a friend and this year got the Jet Black for it (90/disc). I then got a large 2020 SC used this year and had no issues with the wheels going right on that bike as well.
if you tell me how far the bulge on the chainstay is from the axle, I can tell you the wheel width at that location. Assuming the frame is in dish, you can measure the OA width there on the frame, half it, and at whatever amount the cover bulges out.
I suspect if it is just a cover and not that sensor sticking out then you will be OK. I can neither confirm nor deny until we measure the wheel width at the bulge location.

2016 here. Exact same combo. I’m also running 25 Contis 5k without an issue. Yes, I know I should be doing a 23 front, but I prefer the 25 front for feel.
I also know that the disc cover is far cheaper, but I wanted the matching set and didn’t want to deal with the flapping or potential flapping/taping, retaping etc.
This is more complicated to measure than I envisioned, because I did not give it enough of thought. The disc sides are asymmetrical, so I am not going to measure the width at that spot and take half the result.
However, at 222mm from the axle center, the skin is is flat, it is 29mm past the bulge, and is right on top of the spokes. We lace discs heads out, so there is more clearance there than there would be on a normally spoked wheel. Once the skin is bonded on it is at or slightly narrower than the spoke line is on a regular wheel.
If your stock wheels have clearance at this frame bulge, your new disc will also.
That description makes sense. The only reason the clearance is tight on my stock wheel + disc cover is because the cover sits significantly above the spokes. If I press it down to the spokes, there is tons of clearance.
