Bell’s 4Forty cycling helmet is the little brother to the Sixer model and is one of the most affordable MIPS equipped all-mountain helmets on the market right now. With the 4Forty MIPS helmet, you’re getting 15 cooling vents, a sleek in-mould Polycarbonate shell as well as a useful sweat guide. No matter where the trail takes you, the 4Forty is ready.

Boasting the comfort, protection and broadly capable features of helmets costing twice as much, the 4Forty is a bantamweight, all-conditions, all-kinds of trail champion packing a heavyweight value.
