Thank you both
Tourist in MSN and
fietsbob. I ordered the BB tool.
While waiting for its delivery, I need to decide what to do about the crankset, as it seems worn out, particularly the middle (which I expect to use the most) and the large one. I would like to keep the 7 speed cassette and a triple in the front, with 46-36-26 or very similar. Ebay does not seem to offer new-old stock replacements. Any ideas where to source them? Am happy to use other brands as long as they will work with the existing derailleurs. Have looked at the rene Herse triples, but they are very expensive and not sure they will work with the derailleurs. Would this
Velo Orange one work (it looks VERY tempting)?
