It's been all Bauer, CCM, Warrior etc. since around 2006 or something. I think around the time Koho and Jofa were bought out, Tackla dropped off too. So yea it's a niche, maybe even a struggling brand right now. Nobody buys new Tackla equipment anymore and it's sold only marginally. Teams in finnish national league SM Liiga are sponsored and equipped either by Bauer, CCM or Warrior.
My perception of Tackla for the last 10+ years has been that they've concentrated more on rink ball and ice bandy and those sports are dying right now. Obviously concentrating on those sports was a mistake.
