>>1891014Just buy a Specialized Align (or Giant Rev Comp) for 50 bucks. Both pretty aero thanks to minimal vents and nearly the best protection money can buy. Personally I just liked the look of the Lazer Tonic a bit more and found a deal on it so I went with that which was nearly as good. The extra vents suit me since I do long rides frequently in summer.

If you're going to buy a cheapo helmet from Ali Express may as well save on the shipping wait and head to walmart/target. Same price, same quality (being questionable for both), maybe even better.
Some people think MIPS is a marketing meme but from experience I think it works.
