You may want to consider raising your bars to relive the nerve
impingement. I had similar issues with my right arm. Raising the bars
brought considerable relief. However you will get many replies to
bents on brevets. Good luck

This past summer I bought and then rode a recumbent for about 3
months due to injury. I was really happy to be able to continue
riding, but I am also happy to be back riding an upright again. The
longest ride I did on the recumbent was only about 80 miles. I would
recommend starting with a bike you feel comfortable and safe on at
first. The bike I chose, (an used rotator tiger with same size back
and front wheels) had quite a high bottom bracket. The higher bottom
bracket made starting and stopping feel less safe and I tended to get
quite stressed out about the possibility of falling, especially when
tired. You may want to consider getting a bike you feel stable and
safe on for the first few months rather than getting the perfect
randonneuring bike. It can take quite a while to get your recumbent
legs.
Due to its short wheelbase, the tiger can easily be transported in
the back seat of a sedan. Bags, fenders and all sorts of stuff can
also the added.

Weight is fairly critical on rando 'bents. The light ones are more
expensive. The most common unfaired rando-bent is a midracer like Vik's.
For a nearly bolt-upright 'bent position I would recommend an Easy Racer
TiRush, with a carbon fork, carbon hardshell seat and carbon fairing. To
make that type of bike fast you have to use a fairing. The fairing, however,
protects you from weather and makes it unnecessary to draft. Drafting normal
bikes is out of the question with most recumbents anyway (but you avoid all
paceline pile-ups of normal cyclists).
The TiRush can cause recumbent butt (because of the upright seat) during the
acclimation period (about a year). All recumbents require an acclimation
period because you use different muscles than a normal bike. I get the best
climbing results from TiRush-type bikes, because of the direct drive-side
chainline, low bottom-bracket, hardshell seat, laterally and vertically
stiff frame and reasonably light weight. Most 'bents are bad climbers so you
have to be careful when choosing.
Some 'bents (especially the faster highracers) are not designed to take
rando accessories like mudgaurds. Highracers also use 650 tires, so tire
choices are limited. One of the fastest highracers (Bacchetta CarbonAero)
just went out of production because of a shortage of the type of titanium
tubing it uses. I'm not crazy about highracers for randonneuring anyway. I
wish Bacchetta would make a CarbonAero with a 700c rear and 20" front wheel
(to bring the bottom-bracket down to a reasonable level).
Definetly. I like long-wheelbase bikes, perhaps for their high-speed
stability and traffic-friendly low bottom-bracket even though that type of
bike would not be most people's first choice for randonneuring.
I predict that the most-common 'bent of the future will be a 700 x 20
midracer with a fairly upright seat.
Definitely there are differences between LWB and SWB bikes, but I don't
think there is an easy way to answer your question. How a recumbent rider
experiences chipseal will depend on quite a few factors:
- tires & pressure
- recumbent frame design
- seat cushion
- seat angle
My recumbent is essentially a long monotube with wheels at both ends. I
find it acts like a spring and the seat cushion also absorbs a lot of
vibration. I think a LWB recumbent would act in a similar way, but I don't
have any empirical data to compare how a specific LWB and SWB might be
different.
In comparison riding my upright road bike I can unweight my saddle and stand
up, even bunny hop over things, so that is an advantage if I encounter a
short section of bad road. On my recumbent I can't really unweight the
saddle, but the impact is dampened and spread out over a bigger surface area
which is an advantage for long stretches of bad road where I couldn't stay
off my saddle on my road bike.
I have friends who bought and then sold a SWB recumbent because that
specific design transmitted the vibration from chipseal to him in a way he
couldn't stand. He now rides a SWB similar to the Fujin, but from another
manufacturer on the same roads and is quite happy.
Since I ride both recumbents and upright bikes I see occasions on every ride
where I would definitely prefer one over the other. Having had an
opportunity to ride all sorts of bikes I know what works best for me on
different rides.
I'm glad you are enjoying your Stratus. I've never had the opportunity to
really get in a proper ride on one. They look very comfortable and sort of
remind me of a chopper motorcycle...=-)
Safe riding,
Vik

As a non-recumbentist, my guess is that the vibrations from the ship
seal are just spread out over a much larger contact area. I'm just
comparing the surface area of a recumbent seat with that of a regular
saddle and bars. Also, recumbent riders are It seems like almost all
recumbents I see have much skinnier and higher pressure tires than I
use on my upright, so I doubt that's it.

Other than the type of tires & their pressure the main thing that affects
comfort on chipseal or any surface is simply the wheelbase of the bike. The
further away the rear axle (from the rider) the smoother the ride. That's
why long chainstays on an upright touring bike give a smoother ride and
that's why the driver on a tandem gets such a smooth ride.
The back axles on long wheelbase recumbents (like the Stiletto and the
TiRush) and midracers (like Vik's Challenge Fujin) are pretty far away from
the riders centre of mass, hence the smooth ride on those types of bikes.
Hiracers with the back axle nearly underneath the seat give a
correspondingly rougher ride (on rough surfaces).
Some frames give a smooth ride because they are as bendy as a Slinky but you
don't want that kind of smoothness because the bendiness robs power. The
kind of smoothness you do want comes from a laterally and vertically stiff
titanium frame (and steel to a more limited extent). Titanium has unique
harmonic properties that dampen high-frequency vibration, giving a
noticeably better ride over chipseal. Carbon fiber can also deaden some
high frequency vibration.
Seat foam can also absorb vibration.
For those wishing to consider a 'bent for randonneuring, you might look at
the following as well:

This company specializes in hydration and other packs for recumbents. You
will have to rethink the way you carry water and other essentials. Even
lighting or carrying a cue sheet presents very different conundrums on a
recumbent than a diamond frame.
John Schlitter of Bacchetta is planning to ride RAAM solo in 2008. He
discusses his training for this in the blog on Bacchetta's site. Also, I
believe that I read that Randy Schlitter, John's brother, of RANS, is
putting together a team to ride RAAM in 2008. The point is that recumbents
are successfully used in ultra endurance events. John Schlitter's team did
very well in RAAM last year, especially when you consider what a small
population of athletes there are with recumbent experience and training
available to ride these events.
I like my twin 26" (559) Bacchetta Corsa highracer better for randonneuring
than my 20" (406) and 26" (559) Barcroft Dakota. The twin 559 climbs better
and does better through potholes and rough roads than the 406/559. Also, I
need spares for only one size wheel. The higher position on the Corsa, I
believe, lets me see better at night also. That is not to say that David's
thoughts below about a 20" front wheel are wrong. Each style of recumbent
has its own personality and peculiarities. Even different seats make a big
difference in the personality of the same recumbent. These personalities
are so individual that they need to be experienced to know which one is best
for a particular person for a particular kind of riding.

Vyatek (the manufacturer of the CarbonAero) was apparently using the same

Absolutely. The smaller front wheel compromises top speed and so does the
less laid-back postion of a lower bottom bracket. There is an argument to
be made that the CarbonAero hiracer is the fastest non-lowracer (eg
VeloKraft NoCom) rando bike. I'm not interested in being the fastest
randonneur on earth so I prefer to make compromises to suit my tastes. I
feel more confident (at high speeds) on long-wheelbase 'bents and I like
long-wheelbase midracers with a small front wheel. I also use full
mudgaurds so that rules out a lot of no-compromise recumbents (like the
NoCom, ha, ha - note to non-'benters: that's an inside 'bent joke - "NoCom"
is the real name of the bike and it means "No Compromises").
I also like a fairly upright seat for good visibility at night.

That pretty well describes my bikes for a long time now, even before
I started riding brevets four years ago. Less of the French in those
days, and I'll admit I still incline to the British because I find
all that wacky stuff to be much fun.

Lots of those bike choices here, too. Hey, whatever works for that
rider is whatever works!
