Troy Lee Designs A2 MIPS

Yes, the A2 MIPS is engineered for trail and all-mountain riding, featuring a dual-density EPS foam liner that provides progressive impact absorption for both low-speed and high-speed crashes. The integration of MIPS adds rotational force management, which is increasingly considered an essential safety feature for aggressive riding styles beyond basic cross-country helmets.

The TLD A2 MIPS is certified to the CPSC bicycle helmet standard and typically carries an additional ASTM F1952 downhill rating, but it is not certified to the NTA-8776 e-bike standard. The NTA-8776 standard requires higher impact testing thresholds designed for the higher speeds of Class 3 e-bikes, so e-bike riders specifically seeking that certification should look at helmets that explicitly list it.

The TLD A2 tends to fit a slightly rounder head shape compared to the Giro Chronicle, which has a more intermediate-to-long oval profile. Both helmets offer MIPS, but the A2 uses TLD's breakaway visor system and X-Static antimicrobial padding, while Giro uses its Roc Loc fit system — trying both on is recommended if you are between sizes or have had fit issues with either brand.

Yes, the A2 MIPS visor is removable and replaceable, and Troy Lee Designs sells replacement visors in multiple colors through their website and authorized dealers. The visor attaches via a push-pin mechanism designed to break away in a crash to reduce rotational forces transferred to the head.
