3018.0. "Fork goes bump in the night..." by SWAM2::BURDICK_JI () Thu Sep 14 1995 20:55

    I have a Pro-flex 854 with a Girvin (last year's model) fork.  The fork
    has developed creaking and clunking sounds.  I have tightened
    everything up, and so has the bike shop mechanic, but to no avail.  Has
    anyone else run into this problem?  Any suggestion on fixes?  Thanks.

3018.1Grease the MCU?MKOTS3::tcc050.mko.dec.com::larsonWed Sep 20 1995 10:0530
Jim,

I have the same fork.  The owners manual that came with it says that other 
than checking the tightness a few allen bolts, it is basically maintanance 
free.

The only other maintanance procedure is to disassemble the MCU/guide rod 
assembly and lightly grease the guide rod.  This rarely needs to be done.  
They say you should do it only if you feel the shock is overdamped.  But if 
it is time to service the shock assembly, I suppose a dry MCU on a dry 
guide rod would make some noise because of the friction.  Mine only makes 
noise when the front wheel gets airborne and the shock locks out. Just a 
minor "click".  

Also,  I'm sure it has been checked, but my front end was making a creaking 
noise and it was a loose headset.  If that's not it, call Girvin 
(401-765-0130).

I've had mine for 10 months without a hitch...except for when I smash my 
kneecap on those stupid pinchbolts on the stem.  Other than that, I love 
it.  2.5" of non-linear travel really comes in handy...especially when the 
laws of physics force me to lose my line at high speed and I slam into a 6" 
high curbstone-like rock.  I swear, there must have been at least a 
half-dozen major "yard sales" I've avoided due to the Vector.  My old 
Manitou 2 would have had me ass-over-teakettle.

Love my Vector,
Mike

    Chip,  a yard sale (maybe it's just skiers terminalogy) is when 
        one takes a fall, with bits of equipment and clothing 
        scattered everywhere! Looks like a yard sale.

    Thanks for the input, Mike.  My fork has definitely saved me from
    several "yard sales".  The looseness sounds sort of like a headset
    problem, but it has been checked.  I seems to be play in the fork
    bushings themselves.  It is most noticeable going slowly when turning
    through the straight ahead position from one side to the other.  
    
    Thanks for the phone number.

3018.6proflex has shimsSWAM1::BURDICK_JIFri Oct 06 1995 17:166
    just to close the loop - i called proflex and they said they now supply
    shims to remove looseness in the fork.  They also recommended
    inspection of the top ot the fork's steerer tube.  The shims must be
    ordered through a bicycle dealer.
