Review on 🏻 High-Performance Full Speed Ahead Bottom Bike Set 386 Mega Evo English Steel Bearing, 30mm: Enhance Your Cycling Experience by Robert Lee

Works as expected. Note, however, that in my 2019 Topstone Aluminum I have a cable guide that screws into the bottom of the bike. The shaft on this 30mm was MUCH larger than the 19mm it replaced and I couldn't get it in with the bolt because the ends of the bottom bracket spindle are larger than the middle. So I unscrewed the bolt, put in the bottom bracket and spindle, and then screwed the bolt back on. Otherwise, installation requires an FSA tool, which I also knew and bought (you can't use a traditional Shimano threaded cup tool).
