I put the Fulcrum 5s that were on the Bianchi onto my OH's Trek Emonda to replace the stock Bontrager wheels. Our of interest I got the scales out as I was doing this swapping, I reckon she saved 800g and me 200g!
How did it go?

Cleaning bike and wheels ahead of reassembly. Added new cassette to rear wheel. Sanded and used some touch up paint on some paint chips. Will give paint 24 hours then I’ll start reassembling.

Nothing too interesting. My mtb had double punctures and my road commuter had a rear puncture, must've gone down in the shed over the weekend. Also patched a tube on little ones bike while I was at it, need to pick up some 20" tubes for it at some point. Fixed all after work tonight so at least I don't have to use the car tomorrow.
Best bike is currently taken apart ready for a bit of an overhaul at weekend now the nice weather is poking its head out.

Been having a tinker the afternoon with my Holdsworth. I have signed up to do the Manchester to Blackpool Christies ride in July and I think this is the bike I will be doing it on. However when I built it I built it for Gravel so it has the original 26 inch wheels and nice chunky tyres. So I have been playing around converting it to 700c to give me a little more road speed and then i can run some more appropriate tyres. Clearance is a little issue on the front, but just tested and I can fit a 25mm tyre i think 28mm will be fine.
Caliper brakes test fitted on the front fine too.
I have a suitable rear wheel for testing but the rim is damaged so need to hun around for 130mm OLD Rear wheel with a 7 speed freehub.

Rather than what have you fettled today, it's a tale of what I've been fettling continuously this last week. So my first attempt to fit the new Hope caliper failed when I snapped the little brass insert that goes into the end of the Hydraulic hose. So with a new one here it was time to start again. Like last time, it would only go a few mm before refusing to go any further, this time though, rather than resort to brute force and ignorance I mulled it over for a day. I decided to try and gently heat the hose up with a hairdryer and I was astonished when it slid in with barely any pressure at all.
With that done, it was a simple matter to bolt the hose onto the caliper. From there I attempted my first bleed and it soon became apparent that there was another problem that I'd kind of been aware of, but avoiding, namely a sticking master cylinder in the brake lever. This can be common on bikes like mine that are used off-road, year round and subject to a lot of mud being flung up. So nothing for it, but to address that issue, so off came the brake lever and I stripped down the master cylinder. I felt vindicated when the master cylinder assembly (With the spring on in the picture), was stuck in the cylinder, rather than popping free when the pushrod assembly was removed. So with that removed, I gave it a good clean and then a gentle grease with SRAM dot grease.
With that re-assembled it felt like new and it was time to go back to bleeding the brakes. Boy was that frustrating, I bled them and I bled them, it really took some doing to get the air out from behind all four pistons and from the system in general. Hope has a video about bleeding these brakes, which differs from the instructions provided, which differs again to how you would bleed SRAM brakes. Eventually after combining lots of techniques from lots of methods we arrived at today, where after bedding in the pads we're done! I now have a functioning back brake that feels bloomin brilliant and looks fantastic. Let's just see how long it continues like that.

Further to my above I have now swapped both wheels, fitted the new caliper brakes moved the cassette over to the 700 wheels.
I need to remember to order a lockring tool that doesn't have the centre pin so I can use it on my solid axel 26 inch wheels without having to remove the axel.
I am planning a 10km or so bridal path ride tomorrow using the linear pull brake levers on the calipers. I know it's not recommended but I don't want to replace the bar tape and cables untill I am sure I like the new geometry, which I know will not be massively different, but I think it's worth testing first.

New headset bearings fitted, fork inserted, stem fitted, pre load done, bars on and straight, disc brake calliper rebolted into fork. Dynamo light rebolted onto derailleur post, Idler wheels degreased, cleaned then greased, new rear derailleur fitted, rear mudguard bolted back on after all the crud scraped out, rear wheel back in, new rear bar end friction shifted fitted, cranks fitted. Bit of touch up paint applied on paint chips.
All done in increasing heavy rain, I eventually had to call it a day.
To do, fit new chain, new gear cable outer, new gear cable inner, check shifting of both front and rear derailleurs and set limit screws etc. Then test ride to check everything after post winter overhaul. Hopefully I’ll finish the rebuild tomorrow then get a test ride in Friday then fine tune anything that arises from that.
Picture taken part way through, before the rain really came in.

That looks ace, they're great brakes aren't they. Once they're set up
Funny how some of them go without a hitch and others are a real pig to bleed but worth the perserverance! My commuter frame is a very similar colour to that by I went with the opposite colourscheme for the calipers, black with blue piston caps 😊 That works really nicely though 
Looks like we've even got the same discs, but this was originally a SRAM spec'd bike too before I switched it to 105 and Hope calipers, I only kept the rotors

Blimey @JhnBssll , that is a very similar colour, I was also wavering between the black or the blue caliper, it does look nice with the black caliper though. One thing I did do though, is to retain the original SRAM mounting bolts, the heads on them are a little more svelte than the Hope ones and they are a Torx fitment as well. As you said, I had actually just recently fitted new stock SRAM rotors, or I might have been tempted by the Hope rotors.
In the end, it was the advice on the instructions, to advance a pair of pistons and then push them back in with the bleed syringe open, that got the air out from behind the pistons. It still needed to be done a couple of times though. As you say, it's unpredictable about how they will bleed and these put up a right fight, Glad it's done now though.

Fitted new rear bar end friction shifter and new outer and inner gear cables. Fitted chain. I’ve been fettling all week but yesterday’s heavy rain ended yesterdays fettling. Much easier today in sun. Completed post winter overhaul of my recumbent. Test ride tomorrow.
Chains ready to be joined with shorter chain shortened once checked for length big ring to big ring.
Amount of chain left over. Reckon I used 2 1/4 chains for the recumbent.

Fettled the front mech on the vanquish, was getting a bit of rubbing in some gears, now much better and a much smoother shift. It’s not perfect but it’ll do. Ideally I need one of the new tiagra mechs with a side pull hinge instead of a bottom pull that pulls sideways.
