Good morning,

I don’t seem to have much success in repairing pinch flats, where there are two holes about 1 cm apart, normal punctures are fine though. Until it was repaired recently, there was a pot hole on the road that was wide and deep, and you would often get forced into it by traffic or sometimes by forgetting that it was there.

A lot of the stuff that was replaced was the original 7 speed equipment, which is becoming very difficult to get in road ratios, although there is still plenty of mountain bike shifters and wide range cassettes.

So by changing to an 8 speed cassette, the wheels had to be changed and as I didn’t fancy non indexed 8 speed shifting I bought some indexed shifters. The original rear mech was a Shimano 6207, this was the last model made before indexing was introduced and the cable pull is wrong for indexed levers.

I have tried to attach a photo of the broken 105, this wrapped itself and the chain around the cassette causing the damage.

Bye

Ian
