Despite trying to deny it for a while, I have two problems with this chainset:
- I can’t seem to get the perfect bottom-bracket spindle length. Using a 110 mm spindle, the chainline is farther outboard (about 45.5 mm) than I want. I have also tried 107 mm (won’t fit) and 113 mm (worse, of course)
- there is a distinct wobble (close to 1 mm) at the chainring that has persisted through different bottom brackets. I am convinced this wobble is in the chainset as opposed to the rings, because the rings are finely machined while the cranks are roughly forged.
Since I’m sick of badly documented Stronglight products, I’m thinking of getting a cheap Shimano chainset, ideally one that would take my existing 110 mm square-taper bottom bracket and my 34T and 46T chainrings (110 mm BCD). One such option seems to be the discontinued FC-2350, if I can find it.
Should I consider anything else?
Is a certain degree of wobble inevitable with square-taper and avoidable with (for example) Octalink? The Shimano FC-2450 (Claris) uses Octalink.
Thanks for your advice.
