|Ksyrium freehub problem .. need help/advice||12x23|
Sep 8, 2002 4:50 PM
|My freehub skips, just for an instant and intermittently, with a bit of slip as if it's about to give way, on short, steep rollers under max effort. It is a very brief, gear-mesh-then-engage with a little slip, sort of noise. It has just become a problem the last couple of weeks, and I'm losing confidence in my K's when I have to stand and climb.
I know for certain it isn't chain skip .. der stops/cable tension are correct, and chain and cassette are recently replaced. Shifting is perfect.
Is this a Mavic freehub problem that is easily remedied? I've experienced this with my Classic Pros a very few times when engaging the freehub under light or moderate effort after coasting, but I've never had the $&*! scared out of me like I have with the K freehub recently.

|I recently purchased a set K's and experienced a very similar problem. Rode it for a couple of hundred miles before I convinced the LBS into checking out the freehub. Turns out that one of the pawl springs was missing (never installed). The LBS wrench modified a spring from something else that works real good except for the fact that it's a bit stronger and therefore the freewheel noise is pretty loud. I should be getting the replacement spring from Mavic next week.

|I'm gonna have it checked to see. I feel like the problem is in the freehub.|

|The problem I had was when under pressure, i.e. steep hills and low gears, there would be an occasional pop and slip of maybe an 1/8 of an inch that was transmitted through the crank. Oddly enough it also did it occasionally with soft pedalling and high cadence. The bottom line is that since a spring was installed, it hasn't happened a single time and that was about 800 miles ago.

|Sounds like you were riding my wheel. Thanks.|
|Shimano or Campy? If shimano, are you using the spacer???||Paul|

|Souns like your cassette isn't tightening up. This has happen to me with other wheels, I just cleaned and re-tighten the cassette lock ring.|
|Nope. The cassette is tight and||12x23|

|I'm using the spacer per instructions with Shimano cassette. It does sound like pawls failing (or slipping) to engage. I gotta get this fixed, these wheels have been perfect otherwise.|
