Rennen Infinity Bolts are the latest product developed out of the new headquarters. We took one of the simplest components on a BMX bicycle "The Chainring Bolt" and we made it better.
Back in 2008 we redefined the BMX Chainring through our threaded gear innovation, we took something so simple and made it so effective.
Rennen has done it again with the Infinity Bolt. A simple but very effective shoulder just under the head of the bolt serves to distribute the load (see below) and make this the strongest 7075 Aluminium or Titanium 6AL-4V Chainring bolt on the market.
While all other bolts on the market use a 5mm internal hex we chose 4mm to provide more material and increasing their strength further by 8.5%
At Rennen we like improving things that are not obvious and we believe we have achieved that with the Infinity Chainring Bolt.
We are so confident in this design we are offering a lifetime warranty against breakage. That's right break a bolt and get a new one.
For something as simple as a chainring bolt we ran this design through 97 CAD iterations, 22 CNC G-Code variations and numerous FEA simulations.
We purchase USA made 7075-T6 and 6AL-4V Titanium and produce these on a state of the art multiaxis CNC lathe in house. We do things this way because we have full control over our designs and production, and the alternative of ordering parts out of a catalogue is unoriginal and boring.
Rennen stands by their designs and products, the quality shows.
Available Colours are Black, Red, Gold, Blue, and Raw Aluminium or Titanium
Chainring Bolts use a 4mm/8mm allen wrenches for assembly
Regular length has been optimized to work with most gear crank combinations
XL is specifically designed for thick crank spiders like Answer Accelerator cranks.
Titanium Bolts come with 1oz of Finishline Ti-Prep anti seize packet
