Some parts of the Dales gears are a handy thing to have, but round Pately you should fine.
Depends which way you’re heading, but from Pately most do the popular Nidderdale loop (Scarhouse etc), which is fine for the SS (mind you I do run 18-32) – I regularly ride around there, and it’s just as much fun SS as with gears.
Next valley Coverdale can be more of a challenge. K.Malzeard side easier going but not that exciting, Appletreewick side good going – Greenhow hill can be circumnavigated by Bridleway (but still a fair slog), better starting nearer really.
Plenty SS friendly stuff in the Southern Dales, but further north I’d think about using them variable ratio things.
