On a Brompton folding bike, I currently use the following setup:
  • Bottom-bracket: JIS square taper Shimano BB-UN55 68x118mm
  • Crankset: Stronglight Impact 46/34 BCD 110 mm
  • Derailleur: Shimano Tiagra
Since the 46/30T FSA Tempo isn't available with 170mm cranks and the options mentioned above are a bit pricey, I was wondering if it'd be possible to…
1. Get a 50/40/30 triple chainset
2. Remove the 50
3. Replace the 40 with a 46
?

Are there middle 46T chairings, and do you think the whole thing will be narrow enough to fit on a Brompton?

Thank you.
