Chris King's legendary in-house fabrication makes for a Press Fit Bottom Bracket that's smoother and more durable than anything else on the market. They manufacture their own stainless-steel sealed bearings for exceptional quality control, and their angular contact design lets you adjust them as they wear for precision operation and longer life. This 24 mm Press Fit Bottom Bracket fits PF24 frames only and will natively fit 24 mm spindles, but 24-22 mm step-down cranks can be adapted using Chris King's Bottom Bracket Conversion Kits.
Available in multiple colors. 5-year warranty. Claimed weight is 92.5 g.
Ordered by Most Relevant First
I tried a few bottom brackets on my cx bike (bb86) with varying levels of success. SRAM's bottom bracket would last 2-3 months (2,500 miles) and Wheels Mfg's thread together bottom bracket lasted a week (one wet ride and the bearings were toast). Chris King's bottom bracket caught my attention since they make it so easy to service the bearings. Now 6 months later it's still perfectly smooth despite rain, snow, ridiculous temperatures (-20F), etc and takes a whole 5 minutes to re-grease the bearings. OK maybe 10 minutes if the little plastic inserts don't come out right away. My non-scientific assessment says it also spins better than SRAM's bottom bracket and the Enduro bearings in the Wheels Mfg model (hard to tell with that one though since the bearings were gritty before the seals were even broken in).
I'm so pleased with this bottom bracket that I just ordered another for my fat bike.
I knocked off a star on the value rating because it's expensive by itself and then you probably need another kit depending on your crank choice, then the grease injector, special bearing press drifts, ...
