Self-labelled as a ‘classy all-rounder’, that feels about right when talking about the Bell Formula Mips. Best suited to wider heads, it’s relatively light (275g), offers MIPS appeal and a hint of aerodynamics at the helmet’s tail.
Like many here, the Formula bonds the outer shell to the EPS foam to produce a sturdier, slicker and more durable finish. The 19 ventilation channels and internal padding are effective enough, as are the functional retention system and straps, which stayed twist-free throughout (though had to be cut down).
The MIPS is neatly integrated into the retention system, keeping the weight and profile down. We’d choose their eye-catching yellow and black option for added visibility and excitement, though.
Verdict: Ticks nearly every box, but we’d go for the yellow.
