> This is the same bottom bracket that comes with the Race Face Diabolus cranks, so you know it's built to last, but what you might be unaware of is that the Diabolus cups have 100mm extra thread insertion. Not only does this reinforce the bottom bracket shell and reduce the risk of stripping, but it also gives you more scope for fitting chain devices to frames without ISCG mounts. Additionally, the Diabolus bottom bracket can be used for spacing out your BB shell so that you can run cranks designed for 83mm shell widths on standard 73mm bottom bracket shells. This improves the chainline with 150mm rear hubs without leaving your BB cups literally hanging on by a thread. Bearing life has proved reliable and you can't beat a splash of gold on the dirtiest area of the bike.
