Initially I top up the sealant in my Gravel bike tyres. I bought the thicker Stan race sealant this time so I used an old 60ml sealant bottle squeeze it through the valve stem (core removed), rather than wasting the syringe. Given it was the thicker stuff it wasn't fast.

Whilst I was at it I decided to top up the tubeless TT disk in ample time before my next TT and use up the last of the thinner sealant. It went in OK but I think the core was jamming so I had to use a CO2 cannister in the end to force enough air in.

Cleaned and lubed the chains on the 4 bikes used most over the past couple of weeks - those fitted with mudguards!
While doing the Spa Elan I discovered the reason for the occasional chain skipping which I'd put down to a stiff link caused by not re-lubing directly after a wet commute...

This has been replaced with a quick link rather than replacing the whole chain in view of the impeding drivetrain refresh on this bike.
The brake pads were also replaced on the Ventus commuter as the pad holder was getting quite close to the rim.

Puzzle game procrastinator!
IS-to-PM disc brake adapters are not the same size front and rear! I bought one for a 160 mm disc and found that it would not allow me to fit the calliper to a 160 mm rear disc. It turns out to be for a 160 mm FRONT disc. I think it would be good for a 140 mm REAR disc. I now have a 160 mm REAR adapter on order!
The new adapter arrived today and is the right size this time, so now I have finally...




... discovered that the damn brake needs bleeding! :cursing:

I have ordered a bleed kit, which should be delivered on Monday. Hopefully, that will be the last problem with the bike for now! This has become quite an expensive extended fettle though I have clawed back about £40 from a cheaper-than-expected dental appointment.

At the end of this I should have my very nice retro 853 steel hardtail in the best shape that it has been for over 5 years.

Do the sums its about the same weight as about 7 750 ml water bottles . That about the amount of water we carry every day here in Morocco and its quite hilly.😂

Yeah and your bikes are as heavy as dumpster trucks, as agile as a milk float, and slow as molasses. I will not be on a heavy touring bike made from girders. I don’t think so 😂

The turbo was sounding rough recently so I investigated further, one bearing in the freehub was causing the problem, it broke up trying to remove it, so had to heat the freehub with the blowtorch then tap it down hard on the open end and it came out.
Amazon for new bearings delivered next day along with a Wednesday Adams dress for the gran-daughter :eek:
Fitted and back in service, under a tenner for two bearings £60+ for a new freehub,

This bike has been giving me trouble. I'd changed the rear wheel and hub already with no problem, other than having to put in two spacers.

After much deliberation I changed the 7 spd chain and cassette, then the problems started. The new chain jumped in the smallest gear when under load.

I straightened the gear hanger, which had no effect.

Investigations revealed the chain always jumped one link after the joining link. The chain is a new 6-8spd chain. This particular design has a rather bulky looking link piece, so I swapped it for a KMC chain.

It still jumped.

I swapped the cassette.

Still jumps.

How Specific are KMC chains? I'm using a theoretical 8 speed but I'd expect that to have a little more leeway on a 7 spd system, not less. I have a Shimano 6-8spd chain as a last resort.

Other than that I can only think that the spacers are causing problems, these being the only thing I haven't changed. Has anyone else found something similar? How did you solve it?

It is depressingly similar to the unsolvable jumping I experienced on a 9 spd cassette a few weeks ago. In that case I changed the whole thing to an 8 speed and all was well.

Just so you know ,l'm not the first to have the cables on show ^_^
https://www.leboncoin.fr/velos/2256880217.htm

You have shifters where both cables enter from the back designed so they can be hidden nicely under the bar tape. The bike in your link has the brake cables hidden under the tape but the shifters have side entry gear cables which can’t be run under the tape.

My bike below is the same;
