By all standards wax is the best way to lubricate your chain.
Lowest possible friction
Least accumulatiuon of dirt
In the DINvelo formula there has even been added industrial grade teflon and molybdene disulfide.
DINvelo prefers to work with the chains from Connex. They might not be the lightest, but the best craftmanship gives the lowest friction. Add to that, that a chain will add 5 watt to the resistance from every ride without a clean. For the connex chains a propriritary connector can be added allowing dissasembly by hand, ensuring that no excuses exist for not cleaning your chain after every ride:-)
