I did ride a 26er camber expert and had a 29er hardtail a canyon, when I went for the 29er camber I will admit I tried a stumpy first but far too much travel.
Had a blast at CYB not long after getting the new bike, one of my cycling mates is always quicker than me downhill as after a big crash I have a nervous edge, but the camber 29er I beat him and not just a second a good 10 seconds. If I’m completely honest I don’t notice the difference between the 26er camber and the 29er, I did go down a frame size but other than that it feels the same bike. Same travel, good wide bars, the clatter free sram mech is a bit odd as its silent but its the bike I would happily recommend.
