Hope Stainless Steel MTB Bottom Bracket

Description

• External BSA threaded options of Hope’s stainless steel bottom brackets
• Oversized 30mm option for hope cranks. Other models are standard 24mm for Shimano cranks
• The machined aluminium cups hold full stainless steel cartridge bearings
• These custom, Swiss made bearings are double sealed, fully serviceable and removable which give much greater life span than stock units.
• The bearings are made (as all our bearings are) by INA and have been designed to run directly on the crankset axle, without the use of shims or spacers – again increasing life and reliability.
• We use a non contact, free running labyrinth seal to protect the bearing externally, and the machined aluminium centre tube is sealed internally with o-rings.
• The unit is suitable for 68, and 73mm shell width
• Standard 6 colours are available on cups – red, blue, silver, black, purple and gunmetal, with the centre tubes being black
• Weight approx. 113g
