Prices are returning to normal with the fall of the pound.
Bikes, frames and bits have been getting better and better value in recent years, mainly because most are imported and a pound sterling was worth close to 2 dollars, something that wasn’t maintainable.
There can be exceptions though: looking at my main ride (Cotic Simple with Hope hubs, Middleburn cranks etc) it wouldn’t cost much more than it did a few years ago. 10% more perhaps? Not much above inflation over three years.
I think the big shock will be when current UK stocks of complete bikes start running down and the import prices for new ones start hitting the shop floor, it may be enough to put off new riders, and that’s not good in terms of getting cars off the roads on short commutes.
