Long term review. Very capable bike.

This is my 2021 Rocky Mountain Thunderbolt A10 purple/black edition. She has been my ride ever since it came out, I have ridden Kicking Horse Mountain Resort, Mount 7, Fernie Alpine Resort, British Columbia, Cypress Hills/Elkwater and Bragg Creek Alberta throughout the years. I recently upgraded the fork and I freaking love it even more!! This bike handles everything, very effecient on the climb, when it comes down to descending oh man its ready for anything!

Got me into the sport in the best way

It’s been about a year since i’ve got this bike and I’m honestly blown away by how much it can take. From DH trails to mild trail riding, it just performs flawlessly. Lots of travel for a sub 3000$ CAD bike, makes for a stable plush ride while still being very nimble. It’s versatile and packs a lot in a low price. No complaints!
