| RE: seat stays about 3 inches from the seat cluster. Crossing
the seat tube a few inches below the top tube and then joining the
top tube. The reasoning for this is that the real reason for bottom
barcket flex is the weakness of the connections at the seatpost,
toptube, seatstay joint. By making that stiffer, the rider looses
some of the flex which might be apparent otherwise. That's the
reasoning that the scientifically oriented frame builders use. I
think Nashbar did it in copy-cat mode.
Try putting together some pencils using scotchtape for joint compound
and see if the result is a bit stiffer.
As for those brakes: It's aerodynamically sound, looks high tech,
and I'm sure it make the commute to work at least .0001% faster.
Check out a few bike shops, the fancy features this year are
click shifters, multi-color fade paint jobs, and aero brakes.
(It's not my bike.)

I have aero levers on my best bike because they makes brake actuation
stiffer and more positive. The cable is shorter and bound to the bike,
so it doesn't flop around like conventional lever cables do.
Admittedly, I was skeptical at first putting $30 Dia-Compe levers
on $125 Campy brakes, but after riding them for a while they grew
on me. The combination is a lot stiffer than the stock SR setup.

| 348.3 | More ? about the Nashbar frame | BOOKIE::WIEGLER | | Wed Jun 17 1987 12:49 | 6 |
| The point about the frame geometry is one I'd like to pursue further.
The only other bike I've seen with a frame design like Nashbar's
was an old Columbia steel frame that I picked up cheap at a garage
sale years ago. If it's such a good design, why don't other companies
follow the style? Is it just a matter of tradition?

| Another feature about aero levers are that the cables now do not
get in the way when your moving your hands around on the bars. This
you'll notice much more if you use a handle bar mounted computer,
water bottle, or pack. I have two bikes one with and one without
and I find it very annoying dealing with the cables on the bike
without aero levers. One detracting feature is if you have to replace
your cable covers you must remove your handle bar tape.

| re: frame geometry. I think some of it is traditionalism. More
though is quantifiable measurements. I remember a review of a
quality frame a few year back that was built doing this and there
were some measurements that indicated "stiffer." But there's also
an added cost for the frame builder. It seems that there must exist
a pair of lugs which help join the seat stays to the seat tube and
top tube. This would add to the weight of the machine.

| 348.6 | Longer stays, but no extra lugs... | MENTOR::REG | Husqvarna Sonata fur A# saw und vood | Fri Jun 19 1987 14:12 | 9 |
| re .5 I think the seat stays are just brazed to the top tube
and seat tube, i.e. no extra lugs required. Maybe the seat stays
are a bit longer, probably worth the ounce or two extra weight for
more stiffness. I would guess this would have the most benefit
on the bigger frame sizes, difficult to find seat stays a couple
of inches longer than the longest ones though.
