TNT Bottom Bracket


TNT had Ultimate Machine make many of their parts. In 1994 TNT and Ultimate "split the sheets" and their seems to be some animus. The cause of the break-up we don't know, but Ultimate began immediately selling the same parts with the same design that they had been sub-contracted to make for TNT. TNT Performance has improved all their designs. The new TNT Sealed Cartridge Ti B/B is our choice of the finest B/B available. A review of it will be posted here soon.
