I do feel bad for the smaller operators about the situation, but I always get my tyres/chains & sprockets/bike parts from the local guy. In a lot of these cases, you're not going to get it cheaper by importing it.
On the other side of the coin, I firmly believe companies like Monza have been overpricing some of the more popular brands for a long time.
There's two ways all this could go:
1. The manufacturers will recognise the distributor's problems & place sanctions on exporting the gear to locations where there is a local distributor.
2. The manufacturers won't care, because 'a sale's a sale'. It makes no difference to them.
I've seen evidence of it already with Leatt braces, some US distributors have 'US only' shipping on them. I also know of some helmet/clothing manufacturers putting notices on their websites warning about buying from other countries, stating 'sizing variations' (which is load of horse shit).
On the upside for true bike shops, bikes are getting much harder to fix at home. I wouldn't even attempt to open up my CRF, and there would be a healthy amount of road bike riders who wouldn't consider servicing their own bikes.
Looks like the 'services' are where it's at these days. Whether or not that's enough to sustain a business, plus a reduced retail trade, I don't know....
