Product Information
Full details
The Hope T47 Stainless Bottom Bracket is designed for performance cyclists and mechanics seeking a reliable, creak-free interface for frames using the T47 threaded standard and 30mm axle cranksets. Its primary benefit lies in the integration of high-quality Swiss INA stainless steel bearings and advanced labyrinth seals that maximize durability in harsh riding conditions. A potential caveat for users is that it requires specific bottom bracket tools compatible with the Hope cup design, which may necessitate an additional purchase if you do not already own the correct tool interface.

FAQs
Is this bottom bracket compatible with a 24mm crank spindle?
No, this specific model is designed exclusively for 30mm crankset axles.
Does it fit both 68mm and 73mm T47 shells?
Yes, it is designed for both 68mm and 73mm shell widths.
What tools do I need for installation?
You need a T47-compatible bottom bracket tool. Refer to the Hope technical guide or your frame manufacturer's specifications to ensure a match.
Are the bearings replaceable?
Yes, the bearings are designed to be serviceable, allowing you to replace or repack them without replacing the entire cup assembly.
Do I need to use thread locker during installation?
It is generally recommended to use a small amount of waterproof grease on the threads to prevent corrosion and seizing.
Can I use this for mountain biking?
Yes, the stainless steel bearings and labyrinth seals are well-suited for the extra dirt and moisture exposure common in mountain biking.
Troubleshooting
Creaking sound while pedaling
Check that the cups are fully torqued to specification and verify that the crank axle spacers are correctly installed to eliminate side-to-side play.
Rough rotation or grit feeling
Remove the crankset, clean the external labyrinth seals, and inspect the bearing grease. If debris has entered the bearing race, flush with a degreaser and repack with high-quality waterproof bearing grease.

Setup, Compatibility & Care
Installation requires a compatible T47 bottom bracket tool. Ensure the frame shell is clean and threads are lightly greased before installation to prevent galling. The cups should be threaded in carefully to avoid cross-threading; always hand-thread the cups partially before applying torque. For maintenance, simply wipe the external seals with a clean cloth after muddy rides. If the bearings eventually lose smoothness, the seals can be carefully removed to flush the old grease and repack the bearings, significantly extending the life of the unit. Ensure that your crankset uses a 30mm spindle, as this model is not compatible with 24mm or 29mm (DUB) spindles.
