This
past week, I've had two bearings go out on me. Sealed cartridge units
that are supposedly impervious to the elements. Well, mostly, anyway.
The
first was on the front wheel of my mountain bike. I suppose this one
can be excused, as it's probably 16 years old (the wheel, the frame is
only a couple years old), and has spent the majority of the last few
years of its life in an outdoor bike rack at work (mercifully under a
stairway, but
not completely sheltered from the elements). This is the single speed
bike Specialized Hard Rock Sport I keep at work for lunchtime forays
onto the service roads that surround the manufacturing plant where I
reside during the normal daytime working hours. I've purposefully kept
this bike simple and cheap, as it's not locked up (it's inside a gated
secure facility), and it's kept outdoors. I've been toying with the idea
of upgrading the fork to something with more axle-to-crown height, less
rake, and disc brake compatibility, but when I think about it staying
outdoors...
ANYway...
I noticed a squeaking noise as I rode last week, and it didn't go away
when I stopped pedaling. Hm... Okay, not in the drive train. I schlepped
the bike home on my one driving day (I try to bike commute as much as I
can), and checked things out in the late evening hours. Nearest I could
trace was the front wheel -- some slight play in the axle, and a rough
bearing. I replaced that (just happened to have some even OLDER spares),
reassembled, cleaned and lubed the drive train for good measure, and I
was good to go.
The
other was a little more involved, and on my trainer bike. This is an
old Scott Waimea that I've configured as a road bike and kept on the
trainer (I used this one in the "retro division" triathlon I did last
June, so it does see SOME road use). Again, a squeak developed during a
late evening session (I hesitate to call it a "ride"), timed with the
left pedal. I added some NFS lube, and things quieted down for the
remainder of the slog. The
next time I got on, it started up again. Loud! I finished the session,
and then pulled things apart. This one will be a little more expensive
when it comes time to actually replace the parts -- fortunately I had
another bike with the same configuration that I could
cannibalize. What had happened is that the left side bearing had not
just gone rough, it had seized entirely, and the squeaking was the
spindle rubbing against the stationary inner bearing race. Yeah, metal
on metal friction. So not only did the bearing need to be replaced, but
it had worn a nice groove into the spindle. New crank time! I realize
that FSA Gossamer cranksets are a dime-a-dozen and not really
lightweight, and I've got them on several of my bikes. Now I've got them
on one less bike (the one I cannibalized to keep the trainer bike at
the ready).
Sure,
living on the trainer it could be considered to see more harsh weather
than the mountain bike that's stored outside -- not just getting rained
on when I ride it, but SALTY rain. It just happens, no way around it
really, even with a towel draped over the top tube.
So
those are my maintenance tribulations of the last little while. Luckily
it didn't take a
long time to remedy, as I've had precious little of that lately -- the
3-month-old girl seems to want to take up a lot of it...
And a final note for today -- I saw this video on BikeRumor today, and thought it just looked like an interesting, cool race.
