HI, can you confirm it is compatible with Giant Rev Comp helmet? I see no plastic holder in the back of the Giant Rev Comp helmet, and it looks like the manufacturer made an error in product description as on newer Giant Rev Comp helmets I cant see in shop that it would fit.
•
Hello, Giant claims it as well on their website: https://www.giant-bicycles.com/sk/numen-alumbra-tl
•
Yes, but I did a deep dive into this, and because the previous version had the same name, it is only compatible with the older version of the Giant Rev Comp which is not produced anymore.
•
Hello, I bought a helmet from you. Could I order a flashing light for it, which you currently do not sell? Giant NUMEN ALUMBRA helmet light (or alternative) Thank you.
