| Hi,
I have a Paramount Series 5 with the 105sc groupo. It's
only one season old but I find it smooth and reliable.
I've put about 1400 miles on it and have had no problems.
This could certainly mean at least a couple of things, one is that
my sense of smoothness is not that acute or the problem is
with the particular instance of your 105 but maybe not with
all 105s and so on.
Also your comparisons are with groupos costing signigicantly more
money. I would expect them to perform a lot better.
Sorry I can't concur with your friends problem.
Pat

| I know this sounds too simple-minded, but...
o Could the chain be too tight?
o What about the alignment of the chainrings with the rear cluster?
o Are the bottom bracket bearings good? (Crank spins freely with no
chain on it?)
Spinning in reverse is OK? (You said it had trouble moving forwards.)

| Matt,
> o Could the chain be too tight?
Could check that - it's a possibility.
> o What about the alignment of the chainrings with the rear cluster?
Looks ok - will recheck.
> o Are the bottom bracket bearings good? (Crank spins freely with no
chain on it?)
Yes, the crank spins ok without the chain.
> Spinning in reverse is OK? (You said it had trouble moving
forwards.)
Spinning in reverse exhibits same sense of friction (in both
directions this is by hand, not while riding - so it is a subtle
think, I guess). I tried "forward" to eliminate friction in the
freehub mechanism (which in fact was doing fine).
Simple minded or not, those are the only types of things that make
sense. :-) I'll look further.

| How about the rear derailleur pulleys. Maybe they are not on properly...???

RE: rear-derailleur pulleys
Thanks, Tom - they looked ok from a distance, but I'll check.

An update, of sorts...
Pat has been trying out my blue De Rosa (SLX) the last couple
of days (starting Wednesday for 30 miles and including a century
yesterday). Many of her riding difficulties have been corrected
as a result. She says she feels so much more confident on turns
and above 30mph on descents that she can really ride full out,
instead of holding back and being a nervous wreck. Ok, this has
nothing to do with the 105 components, but everything to do with
the Allez geometry, as Bat Buchanan warned in these notes a year
or two ago. The De Rosa, though heavier, is faster ... because the
geometry is right, and you can depend on the bike.
The downside is that until Pat gets a bike of this ilk for herself,
it looks like I've "lost" mine... :-)
Oh, for completeness, I'll still check out the Mystery of the 105.

PS: Her first reaction was, "This is a great *touring* bike!"
to which our cycling companion said, "Oh yes, Eddy Merckx
used it to great effect on several Tours ... de France."

| John,
How about the Jockey Pulley bolts being too tight or pullies not greased? Also
check the rear wheel cones. Are they adjusted correctly?
Good Luck,
Dave
