I can’t really comment on what overseas prices are, but I was always lead to believe TW prices are cheaper because the base discount is 10% off. Depending on the shop, you either get discounts for future purchases or whatever you save with that 10% goes towards purchases on accessories.
One thing that surprised me the most was Shimano/Look cleats. I visited a friend who worked at a LBS back home in New Jersey and a set of cleats were 30-40USD. I can buy 2 sets for that price here in Taipei (from an authorized Shimano or Look dealer too!)
Yah, the one I have on there matched the old bike. Need to buy new ones to match the new bike. Ugh, I thought my spending had ended.
