Giro Cinder vs Giro Synthe: Back-to-back comparison

We are aware that they both are unique in their own perspectives. Giro has created both models with the utmost efficiency. Each rider has different needs and their experience will also be different. So we have prepared a simple comparison to help you out.

I. Comfort: 

The shape of the helmet and the MIPS liner contribute to the comfort level of the Cinder. With the help of EPS foam liner, some direct contact areas are alleviated. The padding is quite good. It is pretty comfortable for both long and short rides.

The Synthe MIPS features Giro’s full-circle adjustable Roc Loc Air fitting system designed to connect the head and retain a slight gap between the head and the EPS foam liner. This helps facilitate ventilation inside the helmet and provides greater versatility for an adaptable fit without bumping the head to the foam lining. This design provides a well-balanced fit around the head for minimizing any points of pressure from the hard foam.

Our Verdict:

Synthe beats Cinder in this aspect. Their chinstrap system and the webbing material is very comfortable as well.

II. Adjustability: 

The adjustability of Cinder is good enough, thanks to Giro’s Roc Loc 5 fit system. On the rear, it has a two-way adjustable dial for a quick adjustment even after the rain or in case you have sweaty palms.

The Synthe offers an extremely high level of adjustment. The Roc Loc internal system can be adapted to a variety of head forms and circumferences. The Y-straps are also used to secure the chinstrap below the chin.

Our Verdict:

Synthe beats Cinder in adjustability as well. Because of the Y-buckles, you can adjust the front and rear chin straps and enable them to stay at a suitable position under your jaw.

Q2. How am I supposed to clean & store my helmets properly?

Ans.: Be gentle, helmets are generally manufactured using materials which can end up being damaged, easily by some of the widely available cleaners. Petroleum-based solvents or cleaners are especially dangerous. These can end up damaging your helmet. Therefore, this can drastically decrease its defensive capability. At times, you won’t be even able to notice the damage that has been done. For ideal results, you are advised to clean your helmet by either using a soft cloth or a  sponge, usage of warm water & mild soap is suggested. Allowing the helmet to dry, fast, that too under normal air & then proceed with storing it in a cool & dry place, there it would not get damaged.

Q3. Are Giro helmets compatible with POV cameras?

Ans.: Some models of Giro have integrated the POV camera mount, which is designed to break away in the event of an impact. We do not recommend mounting cameras or other accessories to helmets since it can end up damaging the helmet or even end up reducing its effectiveness, in the event of any potential impact.
Here, you can learn some tips and tricks about integrating POV cameras on your bike helmet –

Q4. Is it alright if I paint my helmet?

Ans.: We strongly recommend not using any paints or solvents of any kind to be used on your helmets. They can end up reducing this helmet’s protective capabilities.

Q5. Will Giro be offering me a crash-replacement or any spare parts for helmets?

Ans.: Provided that your helmet gets involved in any accidents, then, you will be eligible to even get a discount on newer Giro helmets, as a replacement. For knowing whether your helmet ticks all the boxes, please make sure to email their customer service department with all the necessary details.

Q6. How often should a helmet be replaced?

Ans.: It is a general recommendation for replacing a helmet every three to five years depending on use and handling. This is totally based upon the observation that we made on the average users. A can provide protective capability beyond the 3-5 year recommended lifespan if it is kept in good condition. It is also true that they can end up getting degraded over time. This is why we recommend replacing the helmet within this regular interval.

Conclusion

The Cinder MIPS is a mid-range helmet that is not far from the high-end Synthe helmet. Yes, the Synthe is the better one. It fits better, looks better, has better airflow, and has a nicer finish. But due to its high price, not everyone can afford it. If you have the money to spend and if the helmet fits well, then definitely go for it. But if it’s pricer than the money you looked for, then the Cinder would definitely be a better choice.

I’ve been cycling from my childhood. When I was in high school, I started racing in our local competitions.

At my college life, I took a part time job in a bicycle shop and I learned how to repair and maintain bicycles professionally.

Though I love racing, mountain biking is another thing I do frequently. My friends, neighbors, and colleagues treat me as an avid rider and take my suggestions while they plan for a new bike or a bike gear.
