Renthal SR4 chainring review

Motocross legends Renthal have got a lot of people excited with their new mountain bike chainrings.

The SR4 is every bit as good as you’d hope too. Its drilled, machined and hard anodised looks are fantastic. It’s rock solid, feeling like a complete crank upgrade to several of our testers.

It’s showing minimal signs of wear and tear despite a weight of only 43g for our 32-tooth sample, but then it is double the price of most options.

It’s for a single-ring setup only, but if that’s what you want it’s straight in as our top-ranked ring.
