I recently picked up longboarding. I enjoy snowboarding, but in the current pandemic + climate change it's looking less sustainable as a hobby, so I'm learning downhill longboarding.
Current setup is pictured, links for individual items:
Freebyrd Hiro complete
Larger wheels are cultron, which came with the board as a complete. These are great for cruising, but I am unable to make them slide.
Smaller wheels fitted at the moment are chronicle.
Gloves are lush freeride
Helmet is just my bike helmet, but I should upgrade to a skate helmet soon for side impact protection.
Adidas skate shoes.
I've found the longboarding subreddit very informative, and I enjoy downhill254's tutorial videos, as he includes some theory rather than just explaining how to do the moves.
