In the case of all the $300 and under bd bikes, none of them have sealed cartridge bearings anymore.
Thanks, TT!
So, in the examples that follow - the BD Gravity Attack, it reads "Formula Aluminum Track, bolt-on". The Windsor Clockwork, reads " Formula High Flange Alloy, sealed ball bearing". The Windsor Hour reads "Formula TrackSpec High Flange, sealed cage ball bearing". So this all means that the Gravity has no dust cover, while The Hour and Clockwork do have the covers? I assume that the Gravity has the lesser quality hubs, but are the Hour and Clockwork basically the same hubs? Thanks again.
