Its been 1 month since I have bought my new MTB (Kross globate 1.1) with 18 gears (shimano).. Now the problem is chain has slipped twice while riding. First time my speed was around 25kph and second time it was low around 15kph.
And another point to notice is that my gears are not working properly... chain does not move to other sprocket when I change my gear from rear 6 to rear 5 or vice versa, they start changing afterwards...
What could be the problem?
