The unique beauty of CNC machined (actual real) carbon fiber is special. This is something that simply can’t be duplicated via mass produced molding process’ and/or by using “plastic composite” materials.

When it came time to redesign our all-new Paradigm Bottom Brackets, it was evident there were gains to be had with lubrication. Rather than try to reinvent the wheel ourselves, we simply chose to use the best grease in the industry! All Paradigm Bottom Brackets are assembled utilizing SILCA Synergetic Race Grease which provides up to 50% reduction in friction and 90% reduction in premature wear! Also now available for purchase on our website!

More detailed information to come next month upon official release and shipping of our new Paradigm Bottom Brackets.

All new, top to bottom! A few of the major updates include full disc and 100% real carbon fiber pulley wheels (no mass produced molded parts over here), increased lower pulley wheel size from 18T (previous) to now 20-Tooth, and an all-new bearing cover design. All this results in our lightest, fastest, and most durable Systems ever produced!

It’s been nearly 6-years since our last major release. What we have learned in that time and been able to implement into this upcoming Paradigm collection is immeasurable. 4.27.26.

Because 3D Printed Titanium with post-print CNC machining, that’s why 🤌.

Sometimes (maybe a lot of times) it’s just all about the looks. How rad is this bike that recently came through the shop for a matching Custom Shop painted System?!

A Bottom Bracket might not be as cool or appealing visually as our Systems but they are an integral part in creating a smooth drivetrain!

After the 2025 matching System we posted a few weeks back, we received a number of inquires to match the 2024 model. SO, which one is cooler?!
