bar-end shifters
 

Hello there,

I was reading the Trek Web site, and found the 520 comes with bar-end
shifters.
What benefits do the Shimano Dura-Ace bar-end shifters offer, compared
with
modern integrated shifters? Is the 520 the only modern bicycle equipped
with
bar-end shifters?

Thanks in advance.

The Shimano bar-end shifters are much simpler than STI or Campy Ergo,
and therefore more reliable.

The bar-end in friction mode is much better at shifting between large
differences on the front chainrings than either STI or Rabid-Fire
(sic). It will easily handle a 52-42-24 combination in front (or even
54-44-24 on one bike I rode).

The friction mode will still allow for decent shifting if the rear
derailleur gets knocked out of alignment.

All three of the above reasons are beneficial for touring use.

They last more or less indefinetely whereas STI's die, sometimes fairly
abruptly. Also, the fact that the right has a friction mode and the
left is friction only makes them more reliable in a lot of other ways
that sometimes prove relevant when you're screwed if you can't shift.
And front indexing pretty much always sucks. Shi bar-ends plus the
higher end Shi aero levers (which are the most expensive I think are
made right now except for Campy) are also about the same price as Sora
STI's, which are kinda jank. Bar-ends make a lot of sense for most
bikes and riders.

It's among the only modern US-distributed touring bikes with them,
which is pretty much ridiculous and backwards. I'm not sure how true
that is elsewhere. I've always assumed the main reason why bar-ends
even exist anymore is that Tri/TT bikes use them on the ends of their
aerobars.

Thanks in advance.

There are still quite a few bar end shifter hold outs. Not that anything is
wrong with Ergo and the Shimano and soon to be SRAM equivilents, but bar end
shifters offer the following:

1. More choice in brake levers and shifters.
2. In a crash bar ends are protected and you are less likely to need to
replace them. Brake levers can be cheap to replace.
3. Actually if money isn't an issue, I think Campy 10 bar ends and their
carbon brake levers weigh less than Chorus Ergo. (Not a good reason to
choose bar ends.)
4. It can be good to lift your hands once in a while from the bar to shift.
You have to move your hands around anyway, so why not do it for a purpose
other than
to give them a break from a tiring placement.
5. Maybe bar ends are probably less likely to get gummed up with mud, and if
they are, or the indexing feature fails for some other reason you can use
them in friction mode.

There are other touring bikes and cross bikes with bar end shifters besides
the Trek 520. Cost can be a consideration when manufacturers spec bikes.
Don't think that for 'cross racing there are any advantages to bar ends, nor
for road racing. Tourists and others who like functional, simple equipment
are more likely to be bar end adherents.

One way to look at this is to ask, "Except for racing, is there a reason to
use integrated levers/shifters?"

Many points of view and it boils down to what you are comfortable with. I
run evrything from from Campy 10 Ergo to Suntour Barcons on my bikes. If I
had to live with only one technology, it would be bar ends.

Here are a few benefits of bar-end shifters :
a) should they need to be replaced, they're more economical than
brifters[1]
b) Shimano DA/Ultegra rear bar-end shifters offers both index and
friction mode. This is convenient should you bend your rear derailleur
hanger or damage the rear derailleur itself, both circumstances which
can wreak havoc with indexed shifting.
c) I find bar-end shifters are more durable, having a simpler, more
robust mechanism (less parts to break). Not sure if this is
representative of other Shimano brifters, but in heavy rain my (soaked)
Tiagras frequently skip (fail to retract cable) on the down-shift,
while the action of the bar-end shifters' indexed shifting is much more
precise and positive in all conditions.
d) The left bar-end shifter (friction only) allows for very accurate
trimming of the front derailleur.
e) On a more esoteric note, a single sweep of a bar-end shifter can
up-shift multiple gears; Shimanos brifters (my Tiagra/Shimano 600, at
least) can only up-shift one gear at time. I'm uncertain whether this
limitation applies to newer incarnations of Ultegra or DA.

In short, bar-end shifters emphasize durability, versatility (those
with indexed and friction modes) and economy; they're more suited to
the demands of touring or commuting. I'm not sure if the 520 is the
only 'modern'(?) bike equipped with bar-end shifters, but almost any
bike with drop bars is a candidate - and with the addition of Pauls
Thumbies, MTBs too can be so equipped.

In addition to the answers others have given, I'll add:

I can't stand having anything on my bike that I can't take apart and
repair with relative ease. There should be a difference between a bike
and a Swiss watch.

- with bar-ends, you have visual/tactile feedback regarding the gear
you're
in (I don't see this as an advantage either).

I forgot about this one. I find bar end shifters great at nigth as I can
feel the levers and get a sense where I'm at on the chain rings and cogs.

I, for one, would hate to see bar-end shifters to go the way of the
dodo. While not quite as slick as brifters (you do have to move your
hand to shift) they do include good things like less cost, more
resistance to damage, an ability to switch to friction shift, and
usefulness for handlebars of other than drop persuasions.

No they're not dead yet, Jim.

I use my thumbs to move the bar-end levers without moving my hands.
