Does the propedal work on each of its different settings? I there any damping effect throughout the range, of adjustment or does it only make a difference on the last few clicks of the dial?
EVERY rp23 I’ve ever owned has made wheezy, sucky, gurgly noises from new. Despite what Internet forums say this is not normal – they do make some noise but not so much that you notice it when riding. If the noise is accompanied by the above symptoms then it’s cavitated and needs rebuilding – I’m no expert just very experienced in shoddy Fox Rp23’s..!
Like I said, every one I’ve owned has done this, and each time I’ve sent it away under warranty, they’re come back quiet and fully functioning.
