Find freedom to roam in the modern, well-ventilated Cannondale Sidestreet Bike Helmet. It's light, airy and comfortable, and it brings advanced protection to your ride, thanks to Mips® technology.

- The Evolve version of Mips is designed to bring this tech to a wide range of helmet types
- In-mold construction bonds the polycarbonate outer and foam inner layers of the helmet into 1 solid piece; it's how all Cannondale helmets are made

- IntelliVent system integrates maximum airflow into every Cannondale helmet design without compromising protection
- Inner elastic band automatically adjusts to the contours of your head as you move around, keeping the helmet stable, comfortable and in its optimal protective position
- Born from understanding that no two heads are alike, BioMap Fit was developed to ensure proper fit on nearly any head
- Cannondale designed special shaping and coverage so that their helmets feel and fit like no other, and sizing is consistent across the range

To find your size, position a tape measure just above your ears and about 1 in. above your eyebrows. Keep the tape level to measure the circumference around the largest part of your head and then find the corresponding size in the Technical specs info.

Decent helmet, horrible elastic size adjuster
Could be a nice product, but the rear size adjuster is a deal killer. The elastic rear band may be self adjusting, but it is uncomfortable, particularly if you’re wearing a buff or a winter beanie.

Great helmet :) Small buckle :/
Yes , I recommend this product
Excellent value for a MIPS bike helmet! Comfortable, lightweight, stylish and easy to adjust for a secure fit — I was between sizes and sized up to a Medium, which fit well with room for fine-tuning. My only complaint is the small buckle closure, which can be difficult to operate while wearing gloves or for riders with arthritis or limited hand dexterity. Otherwise, this is a terrific helmet and I was sorry to return it.

Nice MIPS Helment
Yes , I recommend this product
Sizing seems to be accurate. The retention piece is multi-adjustable for a very comfortable fit. Helmet looks good as well.

Great helmet :) Small buckle :/
Fit and look are exceptionally good especially in this price point for a MIPS bike helmet — 4 stars because buckle is small and difficult to remove with gloves on or if joints are stiff — very sad to return this comfortable stylish helmet — Between Size Small and Medium — went with Medium as was easily adjusted and fit well :)

No, I do not recommend this product
Unable to rate helmet, as REI sent a 3 yo product. One star is for REI selling old helmets.

Keeps your head protected!
Yes , I recommend this product
I only had this helmet for about a month before I got in a bicycle accident. Multiple bones on my body are broken, but my head is not. The helmet has several dents on it from the impact of the bike wreeck but my head suffered no damage whatsoever. I think that speaks for itself. I am now purchasing this same helmet again.
