But you seem to buy many things on Aliexpress which is also not local availability, can't you buy those XDR parts in Asia like you do for parts coming from Aliexpress ?

Is SRAM not available in Turkey?

The problem with the current range of Shimano groupsets its that they have now several groupsets completely incompatible with each others: 12s MTB is totally incompatible with 12s road, 10s and 11s MTB for ebike (Linkglide) are totally incompatible with previous 10s and 11s MTB and with current 12s MTB and they now have new 11s and 12s Di2 MTB that only work with Shimano new Steps ebike motor !
They have also now 3 types of freewheels on their rear hubs, the old one, one for MTB 12s only, one for road 12s only.
For road, there is now in 12s only Di2 groupset but customers are waiting since many years for a MTB 12s Di2 solution, the newly announced 12s MTB Di2 isn't a solution, it works only in combination with 2 new Steps motor (previous EP8 motor isn't even upgradable to work with those groupsets).

I previously liked a lot the excellent Shimano groupset but the latest one are a mess !
