Hello, I was wondering if anyone can help. I am about to renovate an old FD Grubb tandem, which has been sitting in a barn for around 2 decades, maybe more. I have cleaned it and now stripped most of it down, and am looking for any guidance or advice regarding dismantling, cleaning and re-assembling the chain set and associated bearings, and the same for the headset. The serial number on the bike is 13965, and I am guessing that it dates from the 1960's but am not sure. Any advice will be gratefully received! Thank you.
