Hashtagg ISIS 128mm Bottom Bracket

Description The Hashtagg ISIS 128mm Bottom Bracket is a lightweight, high-performance option for trials riders running a 128mm crank setup. Designed to offer smooth rotation, strength under load, and reduced weight, it is an excellent alternative to other ISIS bottom brackets in the same category. At the core is an SCM hollow ISIS drive spindle, delivering impressive strength while keeping overall weight low. The unit features double-row 14mm sealed bearings for improved durability and smoother operation under the heavy torque loads typical in trials riding. The aluminium alloy cups and centre sleeve further reduce weight without compromising stiffness. With a standard 1.37″ × 24 TPI (BSA / Euro) thread, it fits most modern trials frames with 68mm or 73mm bottom bracket shells. This version uses M15 bolts for secure crank installation.
