Yeah, I've run into that air leak issue as well...suddenly completely rigid fork is...sub-optimal to say the least.I was mainly after the Avy damper, got tired of the GRIP2. The hybrid coil option was just too tempting not to try, plus my air spring weith secus developer an air leak somewhere lately. The Avy coil weights ~150g, btw.
Which Grip 2 - pre or post VVC compression?
