I had exact same issue. Brake alignment perfect, tried new pads etc, still couldn't get rid of it. Did some online research and after a couple of other people's suggestions I taped a fishing sinker to the top of the caliber bolt. I kid you not it fixed the vibration straight away! I've tested it...
Hey Burners, I broke the rear bolt thru axle (at the quick release) on my BH Lynx 4.8 29er. Does anyone know the size of it? I'm trying to find a replacement and can't find the exact specs anywhere.
My BH Lynx 4.8.
X Fusion Trace fork; 140-110 mm travel adjust.
Chinese carbon 30mm internal wheels
Absolute Black 36T ring with Sunrace 10 speed 10-40 rear cassette
Xpedo Spry magnesium flats
