The product is OK but I do NOT recommend the seller. The pre-sale communication was VERY poor. Finally when purchased, Took MORE than 2 months to deliver. The seller split the shipment to two parcels and have sent it with different carriers. The quality seems to be OK (havn't installed it yet) but store service is very lame. The seller put a blame on me for selecting "wrong" shipment method - what a shame. Finally, the shipment (2nd part) arrived 1 day after expected day of delivery. I can't claim any delay but I'm very NOT sutisfied. Sorry
Parcell arrived in 14 days by Aliexpress Premium Delivery, in one piece and well packed. All components is genuine, and bike mechanic was very pleased with them.
