I bought this bottom bracket for a Genesis V2100 27.5 Mountain Bike from Walmart. The original still used the cheap bearings in cages that were susceptible to water intrusion as they weren't sealed. So far installation went smoothly. The left side cup seemed like it wanted to cross thread so be careful with that; however, I'm almost positive it would be easy to cross thread with any BB if you aren't careful. It feels nice and smooth on the bike and is decently quiet. I wanted the Shimano BB UN55, but it's currently unavailable so I took a chance in this one, and for the time being it seems more than good enough. I'm not going to be riding in any trails, but mainly around the neighborhood and maybe some gravel paths. So far I'm pleased. I will update of I have any longevity issues down the road.
