I ride the One-one 456 with Fox Vanilla R 140mm Coil Sprung fork. As the others say not the lightest but a comfortable all day ride, I find it wanders on steep climbs as my fork doesn’t lock down, I run a Hope 90mm Stem which may be a tad long, my previous hardtails have all been 100mm forks so it may also be my climbing technique! Downhill it really flies, I think the fork makes the difference here. I built mine up following a review against the Orange P7 (which won the test but only due to the Fox Vanilla Fork), the On-One on the test had a RockShox fork fitted. I run mine with a 9sp XT drivetrain, which is faultless. I have just upgraded to a Hope BB, when my XT gave up the ghost after 18 months of riding. The paint is pretty good, a few wear points showing but not excessive rust. I waxoyled the inside of the frame, no signs of rust when the BB was changed.
