I have bought from campyoldy, not the cheapest but the kit I got was brand new from the 70's and I have never heard a bad word about him. Any chance of getting a smaller chainring ?

I am running a 41 on a record chainset, so no smaller and the rear mech is super record and my homework said it should shift upto 28 teeth
or 39T and 28 rear even better 37" gear which I use on all but stupid silly 20% hills where I use a compact ( 34T front )
On old 144mm BCD Record it's 41T minimum.
To the OP a 28T cog with a Super record rear mech didn't work for me. The top jockey wheel crashed into the cog as it shifted onto it and I didn't fancy risking damage to the rear mech. I know others say they run the combination OK but no amount of chain length alteration and moving the wheel to different positions in the dropouts got it working smoothly.
