The Hellbender 70 bottom bracket utilizes a bearing made of 440C stainless steel, providing exceptional ride quality and reliability. The stainless steel bearing in the Hellbender 70 strikes a perfect balance between value and lasting performance.
Chris King Fit Kits make that magical, love connection between your cranks and our legendary bearings.
Your Fit Kit extends the useful life of both your bottom bracket and your cranks, it reduces the potential for noise, and it also allows you to use one bottom bracket with a wide array of cranks, if that’s your jam.
For DUB cranks we have two fit kits to choose from, Fit Kit #1 DUB A and Fit Kit #2 DUB B.
Fit Kit #1 DUB A is going to cover all DUB mountain fitments, as well as DUB road fitments with ThreadFit™ T47 bottom brackets. Fit Kit #2 DUB B is for ThreadFit 30 with DUB road cranks. • For use with ThreadFit™ 30, ThreadFit™ T47 30i, ThreadFit™ T47 30x • 68mm, 73mm, 73mm SB+, 86.5mm, 92mm, and 92mm SB+ BB shells. • Common Cranks: DUB 28.99mm spindle Fit Kit #3 (PBB083) for ThreadFit™ 30 with 30mm spindle cranksets. • For use with ThreadFit™ 30 • 68mm, 73mm BB shells. • Common Cranks: White Industries, SRAM, Race Face Fit Kit #4 (PBB084) for cranksets with 24mm spindles.

We build bearings, so we build bottom brackets. The humble threaded bottom bracket is often the first part installed on a new frame, and the last one the rider thinks about during the life of the bike, but the bottom bracket has a direct effect on pedaling efficiency (read: speed). This is where you put your power into the bike. Having the absolute best interface between your effort and your bike’s forward momentum makes your ride better. The Threadfit™ 24 is how we make bikes that take 24mm cranks the best they can be.
ThreadFit™ 24 fits 24mm cranks in BSA bottom bracket shells. Fit Kit is needed to complete the installation.
Our ThreadFit™ 24 bottom bracket is designed and built to be durable, serviceable, and silent. Manufactured to create the most precise interface between your frame’s bottom bracket shell and your cranks, it makes your cranks spin lightly and easily, without interference, for the lifetime of your bike (with a little regular service). King’s legendary, angular-contact bearings, both steel and ceramic, are the best in the industry, and actually get faster over time, as their contact surfaces wear.
You want this bottom bracket because it offers super low drag. You want this bottom bracket, because it can be opened, cleaned and repacked for years of faithful service. You want this bottom bracket, because you don’t want to think an awful lot about your bottom bracket.
Our Threadfit™ 24 bottom brackets come in an array of beautifully anodized colors and each one includes a Fit Kits that allow our ThreadFit™ 24 to be used with a wide selection of road and mountain bike cranks.

The Threadfit™ 30 is how we make bikes that take 30mm cranks the best they can be.
ThreadFit™ 30 fits 30mm and DUB spindle cranks in BSA bottom bracket shells. Fit Kit is needed to complete the installation.
Our ThreadFit™ 30 bottom bracket is silky smooth and long-lasting thanks to our legendary, angular-contact bearings, both steel and ceramic, the best in the industry. They actually get faster over time as their contact surfaces wear, because we build them to ultra-tight aerospace tolerances, using machined, Delrin-spindle sleeves to create a perfect, and precise fit between cranks and frame. That’s where the low drag and butter smooth feel come from.

ThreadFit 30 comes with a Center Sleeve for 73mm BB shell. For 68mm shell - sleeve PBB082 is required (included in Fit Kit #2 for DUB Road cranks).
We build bearings, so we build bottom brackets. T47 is a standard we helped develop, an answer to the imprecise and often loud press fit bottom brackets that appeared on the market a few years ago. T47 offers the benefits of larger bottom bracket shells, mainly frame stiffness, with the upsides of traditional, threaded bottom brackets, precision and quietness.
ThreadFit™ T47 24i fits 86mm and 92mm shell widths with 24mm spindles. Fit Kit is needed to complete the installation.
All our bottom brackets come with King’s legendary, angular-contact bearings, either steel or ceramic. These are the best bearings in the industry, and actually get faster over time, as their contact surfaces wear.

Enduro's top of the line BB bearing kit, we couple our XD-15 Ceramic-Hybrid, ABEC-5 bearings along with all of the necessary seals and spacers to complete a precise, professional installation.
An Enduro Bearings exclusive, our XD-15 Ceramic-Hybrid bearings combine corrosion-proof, cryogenically treated nitrogen steel races with Silicon Nitride grade 5 ceramic balls in a proprietary process that results in the ultimate high performance bearing setup. The deep-groove design raceways allow for maximum sized grade 5 Silicon Nitride ceramic balls for for increased contact area and improved performance and longevity. 90% fill Kluber NBU52 grease only runs better and smoother with time and is highly resistant to being washed out. It is engineered to stick to the balls and continually be pulled back into the ball path where it is needed. The most impressive feature of XD-15 bearings is, unlike other bearings, they only get better with use. As the bearings wear-in, the balls actually make the races even smoother. So when compared to other ceramic-hybrid bearings on the market that claim speed and power advantages on day one, Enduro XD-15 bearings not only provide the same initial advantages on day one, but will get even faster and smoother with time and use. We are so confident in the performance of XD-15 Ceramic-Hybrid bearings that they carry a limited lifetime warranty against wear and corrosion.
Find out why Bike Radar reported the XD-15 "Hands down, the best bottom bracket we have ever tested". We are so sure that you will agree, that we offer an unlimited lifetime bearing and race warranty.
For the easiest removal and installation of this bearing kit, we recommend the BRT-002 30m x 42mm bearing tool. This tool allows you to quickly, remove and install bearings with a just few twists of the wrist.
The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15 with ceramic or stainless balls. Our bearings are always engineered with deepest groove races possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
Precision machined Delrin® Derailleur pulleys featuring XD-15 Ceramic-Hybrid, radial bearings for enhanced shifting performance and longevity. Designed and manufactured for performance, these pulleys feature CN (tight clearance) bearings in the upper pulley to maximize shifting accuracy and C4 (loose clearance) bearings in the lower pulley to allow for chain-line movement.
500 AF Delrin® pulley material features a high mechanical tensile strength and rigidity, natural lubricity, high resistance to moisture, caustic chemicals and UV makes these pulleys highly durable, rigid and very smooth. Delrin also machines very cleanly and precisely. The in therent lubricative qualities of this Teflon® infused material greatly reduces friction when it interfaces with the bicycle chain. When compared to other pulley materials, 500 AF Delrin® with Teflon®, offers significantly less drag than pulleys machined from aluminum or titanium.
