Cassette alignment
This product is good because of its brand..
Me and my friends bought 5 of this(3 Tempo 1.0 and 2 Tempo 1.1) Found some scratches on the body, maybe during packaging.
One of the bicycle(Tempo 1.0 Metallic gray) had a problem on the cassette. It is not align making it to wiggle. It also causes a grinding sound while pedaling. We need to go to the bicycle shop to repair it and cause around \5000 for the alignment.
Overall this product is good.
