The bearings were shot on my powerfly 4. Bal had a look and deconstructed the rear hub eventually replacing the wheel. the whole job is on warranty with zero hassle. The service and attitude of the staff here is probably the best i have ever received anywhere for anything. They are genuinely there to help you and make the whole experience rewarding. i cant recommend this cycle shop more than that. go there! by your bike there and get it serviced there. If you get to meet Bal in service , stick with him, he's generous with his time and knowledge.
P.S highly recommend the powerfly range.
