Been quite a maintenance heavy week. I decided to change the cassette and chain, and after changing out the chain there was a terrible metallic scraping noise from the front derailleur.
I could not see where it was scraping on the derailleur, so I changed the cabling, reset the derailleur. Still the scraping. Looking at the inner chainring, there was a slight deformity to some of the teeth. Nothing major, but it was enough to keep hold of the chain on each rotation.
So, decided to replace the inner ring, as it had done nearly 3k, but finding one was harder than I thought. These things where rarer than hens teeth, Everyone was out of stock. However chain reaction sent an email the next day, they had four in Stock that day. I grabbed one while they had them, they where all sold by the end of the day…
Dismantled the drive chain, full clean and fitted the ring. All good. Bolts snugged down and ready to go.
Bike rides silently again. Back to the pleasures of silent running!
But getting used to a 12-25 cassette again..
