This is particularly important for racers, but I remember seeing Greg
Lemond crash in two stages of the 1979 Red Zinger when he tried to
look back at the groups he had broken away from -- it happened in both
the Vail and North Bolder Park stages.  He was still a Junior then, of
course, and probably figured out from that experience that this was an
important skill to learn.

The Dia-Compe dual-pivot brakes are closer to a sidepull than a centerpull;
like sidepulls, they rely on the cable housing for some of the actuation
of the brake arm(s).  The manufacturers claim that the dual-pivot brakes
have more leverage than conventional sidepulls.

Why does Performance spec them?  It sets the bike apart from the countless
others in that price range.  That, and it's cheaper for them; no bosses
to weld/braze/align.  You do get improved clearance for feet/calves/bags.
The brakes were designed primarily for fattish hybrid tires (they have
more clearance than regualr sidepulls).  But if one needed (or wanted)
to replace the brake, they'd be forced to get the same one (which may
be hard to find).

Personally, I'll stick to my 987 cantilevers -- or try the "sidepull"
cantilevers when they're available from Paul Component Engineering.

My experience with two recumbents has been that they are no worse to 
maintain then a tandem.  There are three areas where a recumbent poses 
more then the usual repair problem:

1) Small wheels & tires
2) Long chain runs
3) The occasional odd part

The tires and wheels problem can be overcome by using a mail order firm 
like Cyclo-Pedia which has tires, tubes, and wheels in small sizes.  The 
long chain needs to be cleaned a bit more often.  The odd parts have 
always worried me, but I've never broken something that was not a stock 
bicycle item and could be easily obtained.

I have ridden an Infinity, which is a 2 wheel, long wheel base 'bent.  It 
was as easy to maintain as I would imagine most similar designs are 
(Linear, Ryan, etc).  The 2 wheel short wheel base 'bents look equally 
easy to maintain, but perhaps one of the folks who owns one can speak up 
on his maintenance experience.

I am currently riding a Trice, which is a 3 wheeled medium wheel base 
'bent.  It has a few odd parts which would be tough to find, mostly in the 
mechanism which steers the two front wheels.  But so far it has not been a 
problem nor does it look like it will be.

BTW: My local bicycle shop, although they claim to not know very much 
about 'bents, does a terrific job fixing the things I can't figure out.  
It's just a matter of finding a shop who is willing to figure out 
something a little bit different.

>Anyone experienced similar problems, or has an idea what causes them?

Yes I've noticed it too, as well as a friend of mine. As far as I can
see, the strange behaviour starts after about 2 hrs 46 minutes (or
about ten thousand seconds)

What I saw, when I was looking for it, was that the average speed declined
gradually (when I was holding a steady speed above the displayed av. speed)
and then suddenly jumped up. Then the pattern repeated. With an average
speed of about 20 kph, the deviation was up to .5 kph.

From the documentation, it looks like the CC-7000 stores the time in a
decimal format. My guess is that there is a bug in the division operation
which kicks in when the time reaches five digits.

Just a thought: I suddenly noticed from the address that you're a European,
and presumably use metric units. Does anyone know if this problem appears
when measuring in miles as well?

The 737 (XT) pedals have more roataion than the 525 (LX).  There is about 4
degrees free, then more with some return force (XT).  The LX pedals always
have a some return force.  The release tension adjustment also adjusts
(simultaneously) how much centering force.  You can set it VERY low, so it
is VERY sloppy.  Sloppier than the Look arc cleats.  I have the tension on
mine all the way up on the road bike, very low for quick release on the
mountain bike.

They now use a metal plate to fix this.  It comes with the cleats.  The
originals had no metal plate.  I have not had a problem with either ripping
the cleat out of the shoe or undesired release.  I pull up hard sometimes
when climbing.  In contrast, I have pulled out of Looks in sprints and
climbing.

In decades of daily commuting by bicycle I was once hit by a cigar butt,

 I've had good experience with the Force 40 braking system.  Good modulation.
 Unfortunately, you have to maintain the tolerances on your wheels.  This
 wasn't a problem with my Delta V, but I have known people without suspension
 who have had bad experiences with Force 40 due to the increase in maintenance.

 My Delta V came equiped with the Ritchey levers, they offer more than enough
 travel for Force 40.  A good combonation (with the Deore XT cantilevers).

 I know someone with the Dia Compe SS-7 levers with the XC Pro cantilevers, this
 wasn't a good combonation.  Force 40 requires the thick the XT type cables
 to provide a good feel.

Yes, I did make some broad assumptions there, and those assumptions
are _less_ likely to hold for an individual who is at the extremes
in overall height.  However, in general, it is better to fit
someone based on their overall height (IMHO and experience).  If,
for example, and individual has a very long inseam, and you
fit him based on that inseam, you will have to use a very short
stem in order to allow him to reach the handlebars comfortably.
This may not (but may) produce the desired handling characteristics
and load balance fore/aft.

I _certainly_ agree that:
 "It is good sense to be fitted for a bike by someone with
  broad experience, & I've found very few such capabale
  individuals.  This is especially true if you have
  extraordinary height, weight, *or*
  hip-to-shoulder vs. hip-to-ankle aspect.  "Conventional" wisdoms don't
  take these things into account."
This is absolutely 100% true, and much better than advice from
_anyone_ on the net, including the humble dispenser of all
true knowledge :-), yours truly.

This is certainly the most extreme solution.  (Well, OK, so taking the
bike to a framebuilder and having him remove the existing BB shell
and braze in a new one is more extreme :-)).  Someone (Kingsbridge?
Park?)  makes a BB cup remover that fits through the axle hole and
clamps down on the inside and outside surfaces of the cup.  Friction
between the tool and these surfaces allows you to torque on the tool
and remove the cup.  Apply some heat - this will help to free things
up.  You'll want to be careful not to damage the paint.  This is
what I would try first.  Of course you'll have to find a shop
that has one of these tools.

The long skinny portion of A slides through the axle hole

I have three questions about getting a new group for my bike:

1.  (The newbie question)  I still can't figure out the
difference between a freewheel and a cassette.  Consequently,
I don't know if I should get a freewheel hubset or a cassette
hubset.  What is the difference and which is better.

2.  To what degree can I mix components.  If I get a new derailleur,
can I stay with the hub and freewheel/cassette that I have.  If
I get a new derailleur, even though it may handle a 8-speed 
freewheel/cassette, can I still use my old 6-speed freewheel/cassette.
If I can use the new derailleur with the 6-speed freewheel/cassette,
can I still use my 6-speed index shifters with the new derailleur.
Once I switch shifters, do I have to replace the front-derailleur
also.  Are uni-glide and hyperglide chains the same.

3.  Does anyone have any experience with Mavic Components.  Or,
has anyone seen any reviews of them.  I remember seeing a brief
write-up that suggested that they may be better than even 
Campy Record or Dura-Ace, but that Mavic doesn't produce them
enough to be included as stock on any factory bikes.

Geez... I just realized I forgot all my questions marks

Apologies first.  I couldn't seem to reply  to Rob Levy's request

Cycle Trax, 19 Harbor Rd
Highland Cycles, 26 Greig St.
Pedalway, 7 Lovat Rd.
Sharps Cycle Hire, Highland Rail House, Station Square
Thorton Cycles, 23 Castle Street

There are also some package tour outfits, but I have a brochure on auto 
tours hubbing out of Inverness that look ideal for cycling.  Five loops
between 35 and 75 miles.  One goes around Lock Ness (75 miles) and one
goes around the Culloden/Cawdor Castle area.  All five look great.

Speaking of suspension...has anyone tried the Allsop stem? Looks like
an interesting cheap option.
 
And speaking of the other side of the coin..I took a friend over to my
local friendly bike shop to find her a nice bike. After setting up a
Bianchi cross bike to take out for a road test, Barry grabbed a mountain
bike and said here, take this and ride along with her. It was an
interesting looking Gary Fisher with a trailing arm rear suspension.
 
Well, my friend loved the bike she was riding, but I wasn't paying much
attention as I was knocked out by the Fisher. Unbelievably great ride;
the bike just felt alive. I tried riding full-tilt into a curb, without
hopping or unloading- it just snaked right over it. Couldn't hardly feel
the rear wheel hit it. Great bike.
 
Back at the store, Barry asked what I thought of the bike- he had it on
loan from the distributor. Too cool, said I, but it's got to be around
$2500, right? No, it's *$3600*. Oog. That's a lot of money for my kind
of riding, but not for some guys around here. Since then I've heard a lot
of the local racers talking about the bike. Check one out if you can.
