Don’t think the price is too bad. If you think a BFe frame is £350, then add a custom specced carbon bladed fork on top, it’s not unreasonable. (a full carbon TRP CX fork is £380 for comparison). Bikes are expensive these days. You can thank a variety of reasons for that, not least of which is the vote the other summer…
I think the fork was driven by a variety of things and a lot of it’s to do with the availability of aftermarket forks – plenty of people wanted to fit different forks, but getting straight steerer ones is getting more and more difficult, so then you end up sticking the tapered head tube on, at which point steel forks just don’t work aesthetically. There’s also the simple fact that the carbon one weighs a fraction of the post CEN steel one and rides SO much nicer… (yes I have tried both)
The dropouts are a non-issue. The missus has had an original ‘Rat for many years now – pre built-in mech hangers. In a purely urban environment (which is where the ‘Rat is mostly at home) there’s a good chance of it being run SS, and even with gears, it takes maybe 2 mins longer to remove and refit the wheel, and how many times a year do you actually do that?
As far as outdated geometry goes – have you seen the new BFe?? I had a crack on it over the weekend. It’s really quite sorted….
