I was going to save up for the Mosh Justice Cassete hub laced to a chrome Sun Big City rim. Would it be worth it? It runs for $139.99 on Dans comp. It is a sealed hub (four cartridge bearings) with three pawl engagement. It also has a hollow chromoly 14mm axle and a 13 tooth cog. I am also looking to get the Mosh Method sprocket 36 tooth. It is a one peice 6061 sprocket with a chain guard all the way around the chainwheel. I am also looking for a sealed headset but would like some help there too.
