By now, you may have already read about the new Enduro Maxhit headsets . Launched just before Sea Otter started, it appears that the new headsets were just the start of new things to come from Enduro. Now, that same design has been applied to bottom brackets as well which could be very, very good news for bottom bracket durability. Maxhit Design: Bigger Balls, Fewer Parts

With standard headset and bottom bracket designs, a cartridge bearing is dropped into an aluminum cup. Due to the additional material, this forces manufacturers to use smaller ball bearings which are often less durable. There’s also the chance for that bearing to cup interface to get dirty, worn, and be a source of noise.

The Maxhit design eliminates the outer race of the bearing, instead integrating it into the cup itself. This eliminates extra parts, but it also allows for more space for bigger ball bearings. The result is a headset with double the load capacity, less noise, and a wider adjustment range. Of course, it’s not easy to manufacture, with the Enduro Maxhit headset using a 440c stainless steel for the inner and outer races (which only add about 12g compared to a standard headset design with aluminum cups). That’s part of how Enduro can offer a lifetime warranty on the headsets— including a warranty against corrosion. That’s important since you can’t just replace the bearing in these headsets, since the bearing is the headset.

For now, the use of 440c stainless means the […]
