Even in Dushanbe you can find Magura brakes or brake pads!
One our guest had a problem in Pamir with handlebar brake and reached Dushanbe with only one brake, that's amazing and very dangerous !
Fornutately he contacted us and we had both brakes and full set of Magura and reserved one of them.
Even if we don't have you can pre-order the parts.
Hope never dies !
Good luck
Cheers
