product information


PIGMY IASC BB system for20mm axles. PIGMY IASC BB system for20mm axles. (retro compatible to most other similar sliding 20/19mm axle crank systems, and an optional adapter is available that allows Profile's 19mm axle to work inside the IASC system BB.) IASC - Internal Assembly Semi Cartridge BB system. Gusset looked at the common premature failure of MTB cartridge bearings on the existing 'BMX style' cranks using threaded Euro style Bottom Brackets and decided that the significant contributory factor in cartridge bearing failure was the probability of sideload being inadvertently applied by the installer. Therefore, Gusset decided to design a BB system that would make fitting SIMPLE and remove the ability to apply sideload to bearings. Thus, Gusset developed a 'semi-cartridge Unit' system that effectively 'assembles itself' inside the frame. The patent pending Gusset I.A.S.C. BB system installs easily with a UN type tool to give optimised bearing adjustment and additionally forms an effective dirt and water internal shield. The IASC system is also fully serviceable and also allows easy replacement of the individual Industrial cartridge bearings as required. IASC BB Features; Forged Cr-Mo UN style steel BB cups. Variable, sliding chainline. 4 replaceable industrial cartridge bearings. IASC System optimised bearing adjustment. Weight: 246g (inc. spacers)
