I made the upgrade this year from a 26" Ibis HD, that I really enjoyed, to the 27.5 bronson which I am even happier with! I most definitely have noticed better rolling uphill on the climb but do not feel that the agility on the decent has been compromised. The CTD switch on the rear shock and fork is AMAZING. I have a hardtail when i lock it down, a trail rider when I'm on "T" , and almost a full on downhill bike when I drop it into descend. The one part that I wasnt stoked on were the brakes. These were not my favorite; not nearly as responsive and quick as some of the other brakes ive used. The tubeless rims are awesome and have been happy with the tires as well! Tennis ball yellow is definitely the way to go in terms of color. Way cooler than the halloween scheme on the black version. Get this bike if you are looking for a do-anything, all-mountain ripper and you will not be disappointed!
