Ordered my CFR505 about two weeks ago.
Still waiting on paint samples and shipping estimates...

Thanks for all this info Metaluna. I also intend on installing di2 but I didn't know that I needed to specify the correct grommet. Aargh I hope they don't send it via slow shipping. And thank you for the info on the fenders. I was going to order some VeloOrange fenders but I wasn't sure what width to order. Like you, I went 650b with 47mm tires. WTB Byways to be exact. Looking forward to seeing your completed build!

I've got a query into Workswell to see if they sell replacements, in which case I'll just drill one of them and then keep a few spares in case I screw up
I am curious to read the response as I had asked if there would be any issues using Di2 with the frameset, but really did not get an answer. I would think it would be like my Scott Solace road disc frame which has two different inserts for the cable port, one for mechanical and a separate one for Di2.
Okay, it turns out they do have Di2-specific versions of the head tube grommet, so make sure you ask for them while ordering (I assume this applies to Carbonda as well).

It looks like the Di2 version is just a fully-drilled-out copy of the mechanical one, so once I confirm that they've shipped some spares (I don't know the price yet) I will probably just proceed with modifying the one I have rather than wait.

Also, they said the grommet for the FD cable is supposed to be removable as well. I'm trying to confirm if they have replacements for that too, since I'll probably break the one I have trying to get it out. I can get it to wiggle around, but it's in there *really* tight and, because of its location, I can't really get my fingers into the BB shell to get a good grip on the release tab. There really isn't a nice, straight path to it from the outside either, so getting needlenose pliers in there is tricky as well. I'll have to experiment a bit with various tools.

Also, I did a test fit of my 650b x 47mm wheel, and the clearance on the rear triangle is generous. At least an inch from the seatstays, seat tube, and seatstay bridge, and maybe 1/2" or more to the chainstays. IIRC, the front fork clearance was pretty good too, and there should be plenty of room for fenders with these tires. I think Workswell under-spec'ed the tire clearance. I went ahead and ordered some Planet Bike Cascadia ALX 650b x 60mm fenders. The Portland Design Works 650 Beasts are supposed to fit too, though they spec a max tire size of 46mm. They cost twice as much as the Planet Bikes but look much nicer, IMHO.

The good news so far is, even though I've been having a few glitches, I've been getting all the "right" answers from Workswell. Everything is removable and replaceable, plenty of tire clearance, the fork does have a fender mount on the fork crown, etc.

Metaluna, what length bolts did you need to bolt your rear caliper to the frame?

I forget the number off the top of my head, but the ones that came with the calipers in the Shimano Di2 ST-R8070 retail kit turned out to be the correct length for the WCB-R-146 (I think they were the ones for either 20 or 25mm chainstay width).

Cool. I checked my retail box and sure enough the screws fit as well!

I got an email from Coco from Workswell last night telling me they were out of the di2 grommet and were manufacturing more. Bah.

This is some *f##k* bullshit. The rear axle width is 12x142 however the actual axle required is longer than the shimano ax720 qr axle I have in my posession. WTF bike industry. *f##k* your *f##k* 'standards'.

I've tweaked it a bit more since this photo was taken, but this is more or less the completed bike:

Image

The front fender is a PB Cascadia ALX 650b. The pic shows a 700x35 Bontrager NCS on the rear because the Cascadia wasn't mountable at that time. The V-stays the PB ships with were way too short, so I had to order 375mm replacements (https://www.planetbike.com/store/produc ... ay-29.html). Notice how the fender mounting boss is high up on the seatstay instead of down around the dropout. This means a really long reach to the aft mounting tab on the fender (and a really short reach to the forward mounting tab, requring the stay to be cut down)

I also think the front fender might be rattling a bit over bumps, but I haven't confirmed it yet.

Anyway, if I were to do it over, I might give the VO Zeppelins a try, or some brand of 26" x 2.1" fenders, which are supposed to end up being just right for 47/48mm 650b's. Anything where the stays attach to the fender with a "hinge" (like the Bontrager, VO, and PDW 650 Beast) rather than two tabs like PB and SKS do.

Funny story: I was riding a (road) century on the Workswell a couple of weeks ago, and a guy pulls alongside me and asks if that's an electric. I'm like "well yeah, the shifting is electronic" Turns out he saw the fat tires and overall "chunkiness" of the frame (big square down tube, etc.) and thought I was on an e-bike! I said "Nope, I'm pushing those with my legs!"

SC-CX35D - new model on speeder website
flat mount + 15x100 axle + fork with bad internal routing
routing is bad, because top exit is on the rear, not front

Subscribing, as I intend to build an Open UP like bike, but I am too cheap to buy the real thing :)
