I don’t know how base pricing ultimately works, but when the AUD was strong against NTD, I would say things are cheaper here. But now that the AUD has fallen a fair bit, almost everything is more expensive in Taiwan. Even if we take RRP out of the equation though and assume they are exactly the same after currency exchange, in Australia for a non-custom bike, you can realistically get 18-20% off the price in the form of cash, not vouchers or credit.
The only thing I’ve found cheaper in Taiwan thus far is the Shimano DA rubber brake hoods, but even then I had another shop quote me a price twice as expensive!
