A creak-free, heavy-duty bottom bracket for T47 Asymmetrical frames running a Shimano-style 24mm crankset. Enduro builds the bearing and cup as one 440C stainless part, so there are no separate cups to work loose or make noise.

Highlights

• Maxhit design: bearing and cup are one stainless part that threads straight into the frame, with no separate aluminium cups to creak
• Room for much larger balls, giving more than double the load capacity of aluminium-cup bottom brackets
• Machined and ground entirely from 440C stainless steel
• Proprietary double-lip groove seals packed with Enduro's high-pressure grease
• A selection of seals and spacers included for installation
• Limited Lifetime Warranty, kept with an annual clean and re-grease

How Maxhit works

Most bottom brackets carry their bearings in separate aluminium cups, and every joint between cup, bearing and frame is a place for a creak to start. Maxhit merges bearing and cup into a single 440C stainless component that threads directly into your frame's bottom bracket shell. Dropping the extra cup frees up space for much larger balls, which is where the load capacity comes from.

Servicing and fitting

Enduro asks for an annual service by a qualified mechanic: clean the bearings and re-grease them with Enduro Speed Grease (GR-011) to keep the lifetime warranty.

Our Marrickville workshop can install this bottom bracket and carry out the annual service. Fitting is a separate workshop service and is not included in the price.
