I remember back in the earlier days when we could order a strava jersey if we completed that month's fondo or climbing challenge. For example: https://www.strava.com/challenges/gran-fondo-06
In retrospect I wish I'd ordered one before the feature disappeared. I'm guessing it must have either not been popular, or not been profitable. Yet... if you google "strava jersey" you will find literally dozens of knock-offs being sold by various retailers (I'm guessing those are all unauthorized as I doubt strava allows their trademark to be used like that, but maybe I'm wrong). The quantity and variety would indicate to me that there is a demand for it.
From a marketing standpoint, getting your users wearing your swag is ideal. So I'm wondering if maybe the cost of the small-batch jerseys made the price too prohibitive, and maybe that was the problem? If so, maybe some less-expensive items would be worth trying, as the OP mentioned. I'm personally not into stickers, but I know a lot of people are. My kids collect them for their water bottles. Then think about all the 26.2 stickers you've seen on cars. If strava could come up with something as culturally relevant as the 26.2 sticker, it could be a huge win/win from a marketing standpoint.
