Quoted message said:Hey I was looking at a new road-style bike, and see two new styles of
brake levers (new compared to my Schwinn Tempo's downtubes).
What are the differences and advantages of bar-end shifters on the
downtube, vs. little fingertip shifters inside the brake levers?
If I build a bike, I hafta choose one.
Differences/advantages are more personal taste than anything else, IMO.
The old school downtube shifters were standard for racers for a long time
because they were lightweight, simple, and the shorter cable/cable housing
run made for more accurate shifting. Improvements in cables and cable
housings (teflon lined housings, more tightly wound cables) reduced the
difference between down tube mounted shifters and bar end shifters or
integrated shifter/brake lever setups. I used downtube mounted shifters
until about 3 years ago, and I liked the simplicity, especially with
friction shifters, but I didn't like the way my knees interfered with my
shifting hand if I tried to shift while pedaling. YMMV in this respect.
Bar end shifters are easier to use, you don't have to take your hands off
the bars to shift and the position of the levers gives you an indication of
what chain ring/cog you've selected. I find myself sliding my hand back on
the drops and shifting with the side of my hand or with my little finger,
which is really easy. I run friction only (no indexing) bar ends from
Rivendell (www.rivendellbicycles.com) and 8 speed cassettes on my touring
and commuting bikes. It's a very dependable setup, modern derailleurs and
cassettes shift so nicely that you don't really need indexing. 8 cogs in
back are plenty for touring/commuting, and 8 speed chains are cheaper and
more durable than 9 or 10 speed chains. There are still a lot of good
quality 8 speed cassettes on the market if you look.
Integrated shifters/brake levers (brifters) are really nice for fast,
workout type rides on a road racing bike, which is where I use them. With
modern dual pivot brakes and integrated shifters/brake levers you can ride
with your hands on the brake lever hoods and brake and shift without moving
your hands from the hoods. One drawback is that the brifters only work in
indexing mode, so if anything goes out of whack (kinked cable, cracked cable
housing, etc.), your choice of gears will be very limited until you repair
the problem. Another problem is that a combined shifter and brake lever
costs at least as much as the two separate components, so crashing is
expensive. Campagnolo makes a really nice, dependable, repairable
brake/shifting system.
