Information

Praxis Works Steel eRings are specifically made for e-bikes and for longer durability. They have an integrated thread for the chainring bolts, which creates more space in the tight installation space around the mid-engine.

Technology:
Praxis Works eRings feature the WaveTech tooth arrangement developed in collaboration with MRP. The teeth are alternately positioned further to the right or further to the left of the chainring center, creating the characteristic wave motion when viewed from above while the crank is rotating. The WaveTech design reduces friction in the system and ensures that the chain is held reliably even in adverse, muddy conditions, as the extra space means that dirt has less room to hold.
WaveTech also ensures less wear because the load from the chain is distributed more evenly and over a larger area.
