Unfortunately, I have had a string of issues with the bike, which means its off road until parts arrive.
Recently, I replaced the chain and cassette, but on subsequent rides, the noise from the chainrings was a steady grind and occasional clank as the chain struggled to mount the teeth. It appears the inner chain ring is worn off the old chain. Strangly, its almost two years to the day I last replaced it. Now, removing the chainbolts, two sheared off when placing back into the crank. So not only have I to replace the worn chainring, I now have to source 4 crank bolts. Ah well.
I had been looking at getting Absolute Black chain rings, but money is very tight at the moment, so I’ll stick with the standard Shimano internal ring. ChainReaction where wanting about £20 for a ring, but as I was looking round, bike-discount.de was offering them at about €8. So that was a no brainer. The crank bolts however, are stupid expensive. EBay was the cheapest I could find, at about £25 for the 4.
As the Ultegra crankset is no longer produced, and I have no desire to install the new 8000 series, and its dérailleur, I might just go with the Absolute Black once the outer chainring wear becomes an issue.
