What Have You Fettled Today?

Whenever I try, I somehow end up with a spring, 2 washers, and a strange little metal plate that I forgot to put back in!

I am always amazed at programs like The Repair Shop when they take things apart, ie clocks. If I did that and then put it back together, even if it did work I`am sure the clock would go backwards. But then there is nothing like going back in time !

Unraveled the mystery of the TPU leakage.
Turns out that I've had overseen a second puncture and applied the patch so that the second puncture was very near to the edge of the patch. With little pressure the adhesive power was strong enough to keep the patch and the inner tube together and therefore I couldn't find the leakage. But with high pressure within the tyre the pressure from the inside was stronger than the adhesive power and the air creeped out.
Unfortunately I couldn't remove the adhesive from the first patch completely, so the subsequent attempts to patch it were unsuccessful.

On the plus side: Now I know that TPU inner tubes can handle a bit more pressure than anticipated to locate the punctures and the many tyre-off-tyre-on-tyre-off-tyre-on in the last two days were good practise for changing tyres.

Uninstalled the Shimano Tiagra brifters and hydraulical disc brakes from the Van Rysel NCR AF and shortened it's steer tube.

I decided the Black Hallett could do with a bit of tlc, bring now nearly seven years old. So a new chainset seemed in order. I had to do a bit of research to find the right middle ring - it comes with a 36 but I wanted a 38.

I also fashioned a lightweight saddlebag support for the fixed.

Ebay Mavic Cosmic Elite wheels arrived - sold with seized rear hub. Basically these wheels hadn't been used in over 10 years and the grease/oil in the Mavic FTS-L hub had gone sticky. Really easy job to strip. Then checked hub bearings, and the grease was totally clean.

Zero wear on the braking surface - the original milling hasn't worn off. Did order £40 of bearings to fix, but not needed. They will go into stock.

Don't buy Vittoria Corsa N-EXT. No wonder they were cheap.

Impossible to get on the rim. Even one side was a huge struggle and there was no way the otherside was going on. Even had to cut the tyre off the rim to remove it as it was so tight.

£20 a tyre wasted. I'll get some Rubino's or Lithion tyres instead.

Strange.
Have them (but in 32mm and 34mm, not 26mm) on several rims like DT Swiss and Rigida DP18 and it was no problem at all to get them on and off.

Seemingly your tyres either are from a monday batch or it's a problem with the 26mm model. Which rim do you use?

Mavic Cosmic elite. Could be that they are TLR and just not compatible with my rims. The 26c is mega tight.

Mavic Cosmic elite.

An older generation which isn't specified for tubeless?

Sorry - I didn't mention that I wrote about my experiences with the tube type (tubemore?) version of the Corsa next, not the tubeless.

Tubeless tyres on tubemore rims usually is... difficult - to say the least. Been there with Tufo gravel tyres and Vittoria Ridearmor. Fortunately the beads can be elongated-stretched-I-know-the-brabble-in-one-of-the-other-threads slightly ahead of the installation. Done so with the Tufos by putting them on the rim (H plus SON TB14) as far as possible and then placed two tyre levers from the opposite side of the rim so that they catch the bead of the tyre when I lever the bead over the rim. In that situation the bead has a lot of tension and (hopefully) eventually the bead backs down. The Tufos did so.
The Ridearmor were slightly less uncooperative on Remerx rims. I could put them on them eventually without damaging the inner tube. After a week or so with maximum pressure it was notably easier to get the tyre off and put it on again.

Fingers crossed that at least one of these methods works for you.

Never had an issue with MTB tubeless ready on tube rims at all, but the road in 26 are super tight on an older tubed rim. My mistake.

Ordered some 28c Lithions. Will be used on the CX bike for road and some bike packing (on road).

A little more fettling of the Cosmic rear. Appears the previous owner had tried to fix the freehub, but when I fitted it to the bike the freehub locked up. Pulled it appart again and removed the end cap on the freehub and found the spacer washer wasn't in the right place inside the hub. It was behind the endcap between that and the bearing. It shoud have been on the other side of the bearing. Removing the end cap allowed me to check the internal bearing, again totally clear grease so packed more in.
