Bell kids helmet review
Simple, and easy to use rear adjuster on the Sidetrack II
The Bell Sidetrack II helmet in use
The straps on the Sidetrack II helmet are great and the buckle is a clever design to prevent pinching.
MIPS is becoming more and more common on kids helmets and although there is a price implication.
Overall verdict on the Bell Sidetrack II helmet
With strong colours and a striking peak, it may divide opinion, but at a functional level, the Sidetrack II is hard to beat. The attention to detail in the adjustments and fit are fantastic and complete a great package.
