Bottom Bracket Conversion Kits

You may not be able to change the bottom bracket shell on your bike, but a bottom bracket conversion kit lets you adapt your bike to almost any crank and drivetrain setup you want. JensonUSA carries a wide variety of solutions including eccentric bottom brackets for single speed setups; adaptors that let you run a traditional threaded bottom bracket in a frame that has a BB30, PF30 or other press-fit BB shell; plus any kind of spacer, washer, bearing or clip you might need.

Eccentric bottom brackets help optimize the performance of a single speed drivetrain. The offset opening allows you to adjust chain tension by simply rotating the bottom bracket. We offer eccentric bottom brackets from specialist brands including Wheels Manufacturing, Niner and Orgin8.

In addition to adaptors and conversion kits, we also have a full selection of bottom bracket replacement parts. From sealed bearing kits to crank bolt assemblies, we stock everything you might need to repair or overhaul a bottom bracket without having to replace the whole unit.

So don’t give up on any mismatched frame and drivetrain setups. With our collection of bottom bracket conversion kits and adaptors from brands like SRAM, Easton, FSA, Truvativ, Wheels Manufacturing, Niner, Race Face, Surly and Origin8, there’s a good chance we can help you find a solution. If you have any questions, feel free to call one of our expert Gear Advisors today at 951-234-7554.
