This is the robust version of TNT’s flagship bottom bracket, the TNT Ultimate Nitro Titanium Superlight.
The extra strength is of benefit to those who are harder on their components, while still wanting to keep the weight down.
The most obvious differences being the deeper adjustable cups/lockrings on each side and a hollow titanium axle with shoulders – as this is a more traditional non-floating axle version.
Complete with high quality sealed cartridge bearings and aluminium cups and bolts.
Shell: 68mm, 73mm
