I will lose a little top end, but doubt it would be ever noticed. If my math is right, a 90rpm cadence on a 700c wheel would still have me cruising at a bit over (30mph), and since I could never cruise that fast and I’m not a sprinter, I seriously doubt I would ever miss it.
The 43/10 top gear is like a 48/11 and in between a 50/11 and 50/12. I can spin it up to 38mph at about 113rpm.
FYI, some sellers have reduced prices on the 3 piece build kits by up to $600. A complete group, with cassette, cranks, cassette, chain and brakes should be well under $2000.
