Ideally I'd like a range of 15 to 19 for track/crits to medium gear TTs.
The current chain length would just about allow 52 x 19 but 50 x 15 would be near the end of the dropouts, and I can't get 50 x 19 with one less link.
Half link in the chain?
How would 48-18 work instead of 50-19. Two chainrings and a set of cogs would give you loads of options
