I spent some time last night working on this. It's a transverse mount for the XT Di2 display to enable it to fit onto aero extensions, which I can admit is a pretty niche use case. I discovered that I needed this when I went to dry fit the various relevant front end components to sketch out how things would sit relative to the steerer tube battery and found that there was not enough free space on the clamp area of the handlebars to fit the normal 31.8 mm display mount, and even if there were the screen would be directly underneath an elbow pad.
The clamp on the display can be removed and replaced with a 35 mm version because this is a mountain bike product. It's held in place with one screw, which keeps the various protrusions and recesses on either side of the interface mated to one another. I recreated the clamp side of the interface using Rhino, a pair of digital calipers, and some phone photography.
This was a relatively quick prototype, with the primary aim of getting the interface with the display right. It basically fits, although it is a little tight and I will fix that in the next iteration. On the other hand, the clamp is too thick and won't open up sufficiently to fit over the bar without removing the grip. Also, the rest of it needs a lot of work: there's a whole bunch of extraneous bulk, the connection between the display interface and the clamp is unresolved, there are no chamfers anywhere, and it is not aerodynamic in the slightest.
I currently intend to have it on the right of the right aero extension, which may be a little awkward because when I'm in the tuck my arm will be exactly on top of it, but since I don't have bar end shifters yet it's not like I'd be able to change gears anyway. The other mounting position I am considering is on top of the stem, which I think would look better than it sounds because the display would be shrouded by the aero bars.
This prototype was printed in ASA because I have a lot of ASA, but I will more than likely print the final product in carbon fibre PETG because it is my bikiest material.

Thanks! I don't, but the Cannondale was more or less stock other than the bars having been switched for drops, so it looks something like this. It also came with a pair of normal wheels (Open Pros on 105 hubs), and the seat post being a Thomson was a pleasant surprise. There are a couple of things missing - most notably the right STI - but my aim is to sell everything to make the Spinergys effectively free.

On the Spinergys, I think the risk of failure is probably not actually too bad. In addition to my being lightweight and basically pretty careful, they're a late-model X-tra Lite with serials in the 300000s, no visible damage and very light brake track wear. From what I've read, the serials place them among the last Rev-Xs that Spinergy made, by which point they'd addressed the issues that made the earlier iterations failure-prone. (I believe there was only one model after this, the Team, which had the more 2000s-looking logos and combined the titanium axle and internally drilled out rim of the X-tra Lite with the double-layered spokes of the Super Stiff.) I got these attached to a 1999 Cannondale Multisport 4000 with DA 7700 that I drove eight hours there and back to collect along with some other stuff.
As for the rest of the components, I've purchased everything and am just waiting for it all to arrive. The above pictures are a dry fit to get an idea of where the contact points will sit - I've never had a 650C bike, or a bike with risers, or a bike with aero bars before this. The silver stem is a 90 mm Kalloy destined for my Colnago; I've ordered a true chode 60 mm also Kalloy in black to try to get vertical upper arms in the TT position. In addition, the SLR Superflow, which I've had for about a decade and never found comfortable - and which is absolutely not suited for riding in the aero bars - is being replaced by a Bontrager Aeolus Elite that's en route. The slightly jaunty/unfortunate saddle angle is probably going to have to stay since it compensates for the flex in the beam when it's loaded; fingers crossed it looks less goofy with a less flat saddle.
To do next:
- Design and print steerer tube battery holder.
- Drill frame for Di2 (scary).
- Rebuild brake calipers.
- Design and print steerer tube battery holder.

After doing a bunch of research looking for a pump in this category, it came down to the Birzman Mini Apogee and the Topeak RaceRocket HP/HPC for me. I ended up picking the Birzman despite its potentially worse usability (no hose, no grip) because it's quite a bit smaller, and will just cross my fingers that my good luck with punctures continues. I'm still waiting for it to arrive so I won't be able to provide impressions for a while (hopefully ever).

I also picked up some other wheels. I remember when my plan for this bike was to just clean up the 6400 groupset that it came with.
Obviously, I have a decision to make - I can't really justify keeping two sets of luxury 650C spoks around for one 650C bike. The Hed 3s are certainly a better wheel, but there's something really nice about the Spinergys on this frameset. They speak the same language: the blades resonate in both the beam and the fork, not only in the tapering, lightweight form but also in the material and its texture. Also, the decals match.
The Hed 3s aren't chopped liver but they just don't talk to the frame in quite the same way. I can acknowledge that they're a much better wheel - and much less likely to fail catastrophically - but I'm leaning heavily towards selling them and keeping the Spinergys.
-
Until I received the tires I didn't do much to the bike itself, but I did do some things on paper. In addition to working out the rest of the build, I sold the 7800 groupset at a small profit, as well as the cassette that came with the XT Di2 since I want to start with a completely fresh drivetrain. I also picked up some wheels.

Yep, they're 650B. As far as I know, the only somewhat available modern folding 650C tires are the Vittoria Rubino Pro and the Schwalbe One. In theory there's also the Panaracer Closer Plus but nobody sells them. Also, all three are 23 mm.
The 28 mm Paselas that I ordered finally arrived, and they're not 28 mm inflated - more like 25 mm. They're clearly marked as 28 mm both printed on the label and embossed on the sidewall, so I don't think it's just a production error. I wouldn't be surprised if they just use the same casing as on the 25s; as for why they'd do this, I'm not sure.

The clearance at the chain stays with these on is safe but I think any wider might make me a little uncomfortable. A true 28 mm almost certainly would rub, so this is a blessing in disguise in a way. I was half expecting them to come up narrow because when I was searching for information on wider 650C tires, I remember reading on a recumbent forum that the 28 mm Terry Tellus (which is also made by Panaracer) is not actually 28 mm.
Do you know if the folding Schwalbe One or Vittoria Rubino come out any wider than the listed 23 mm?

Many months have passed since my last update.
I find it hard to build bikes piece by piece over time, so my projects tend to involve a lot of planning before a rapid succession of purchases. Part of the reason for this is that I like to establish a coherent vision for what the bike should become, and another part is that I like to not get destroyed on shipping from Europe so I min-max my carts to the nth degree with the aim of making fewer but larger orders. I map everything out in a spreadsheet so that I can get a clear picture of where the bottlenecks are.
Some things are only available from one retailer, which makes those decisions easy. One such thing for this build was the tires. I found a listing for 28 mm Paselas with black sidewalls at Starbike, 'ready for sending in two to four business days', and seeing as there was nothing else wider than 23 mm for 650C available anywhere else, I basically immediately purchased three along with a riser bar for my new hybrid plans. Unfortunately the quoted business days were much longer than normal days, because the order didn't arrive for another three and a half months - apparently due to supply issues from Panaracer's end.
Anyway, I have them mounted now, and as you can see, they're nowhere near 28 mm. A little disappointing, but I'll live - they're black, they're wider than 23 mm, and they're here. It may actually be for the best that they come up narrow because there's not a lot of extra clearance between the chain stays.

Looking good! I hadn't checked this thread since I added myself to the first list, so I didn't notice that I didn't get moved over to this one. Any chance I can still make it into this batch?
