MULTIPULSE SYSTEM. The MultiPulse transmitter
ring contains 20 magnets. As it passes the receiver 20 pulses are generated
each wheel revolution. Data is on-line and not clipped or averaged. The
reed switch system used by most cyclocomputers generates only one pulse
per wheel revolution. It loses accuracy at low speeds and is sensitive to
vibration. |
|
USER-FRIENDLY INTERFACE.
Functions are grouped logically. The right button moves from function to
function, while the left button selects subfunctions. Actions of the right
and left button are consistent throughout operation and setup.
|
|
HIGH-RESOLUTION PRECISION.
Precise data from the MultiPulse system is utilized by the high-resolution
displays. Current and maximum speeds are displayed with .1 mph resolution
and average speed to .01. Trip distance reads to .01 mile.
|
|
INDIVIDUAL AND GLOBAL RESET. Maximum speed,
average speed, trip distance, and the stopwatch can all be reset independently.
There is also a global reset that zeros all these functions together |
|
POSICLICK BUTTONS. The buttons give audible
and tactile feedback when pressed so you can switch functions without watching
the display. |
|
EASY MOUNTING ON ROAD OR MOUNTAIN BIKES. The mount kit includes receivers for both mountain
and road bikes. The pivoting mountain receiver is simple to install on virtually
any mountain bike fork, suspended or rigid. An aero wheel adapter is available
separately for Spinergy and tri-spoke wheels. It moves the transmitter ring
out from the hub flange on wheels that have narrow hubs. |
|
SPEED. Low speeds are displayed down to
1 mph. The Cyclometer uses speed data to calculate distance, and in mountain
biking, good low-speed sensitivity ensures that distance will not be lost
during low speed climbing or while walking unridable trails. The speed display
is updated every second. With immediate, high-precision speed you can gauge
your performance and smoothness clearly. |
|
MAXIMUM SPEED. You can find the maximum
speed for your ride by doing a global reset at the beginning of the ride
and checking maximum speed at the end. You can reset before a descent or
a sprint to find your maximum speed for that particular part of your ride.
Maximum speed is an important performance indicator in sprint training,
and you can track your progress if you reset before each effort, then check
the maximum afterward. |
|
AVERAGE SPEED. The Cyclometer 45tt displays
true average speed. It only averages when the bicycle is moving. Its ride
timer calculates average speed independent of the stopwatch timer. Time
stopped at traffic lights or rest stops on long rides such as centuries
will not reduce your average speed. With 0.01 resolution you will immediately
see the results of speed variations on your average. If you measure your
performance by average speed on a course you regularly ride, the Cyclometer
45tt will show your progress precisely. You can measure average speed for
an entire ride; or, for training, you can reset often to check performance
on specific sections of a ride. This resets the Riding Time/Riding Distance
function and gives you a time and distance for that section. |
|
PACEARROW. The PaceArrow, displayed in
all functions when the bicycle is moving, indicates whether current speed
is above or below average speed. For training, the PaceArrow is most effective
on a rolling route. To keep the arrow pointing up, you will have to work
hard on the uphills, then use the downhills for recovery. You can adjust
the difficulty of the workout by resetting Average Speed more or less often.
The PaceArrow and Average Speed make unforgiving taskmasters for those who
like hard training. |
|
CADENCE. Cadence is the rate of pedaling
- the crank rpm. Most coaches recommend that cyclists learn to ride smoothly
while 'spinning.' Although cadence varies with speed, terrain, and riding
style, many riders tend to let cadence fall when they are inattentive. Checking
cadence will prompt you to keep your pedaling steady. |
|
GEAR SIZE. The Cyclometer
45tt displays gear size in gear-inch, the traditional method of gear measurement
in the US and Britain. When the Cyclometer is set up to read in kilometers,
it displays gear development, the distance the bicycle travels each crank
revolution. Gear-Inch will tell you if one chainwheel-cog combination produces
a gear larger, smaller, or equal to another. You can see whether you have
duplicate gears, and you can establish a logical shifting sequence. |
|
TRIP DISTANCE. Most
riders measure trip distance for an entire ride and zero the display with
a global reset before they start riding. The high resolution of the Cyclometer
45tt's Trip Distance display, and the Cyclometer's excellent low-speed sensitivity
give extremely accurate trip distances. |
TOTAL DISTANCE. This
is the Cyclometer's odometer function. It keeps a permanent record of distance
travelled. If you want to record yearly mileage, you can zero total distance
before the first ride of the new year with the Total Distance Setup feature. |
|
DESTINATION DISTANCE. In a time trial,
you can enter the course distance in advance, then activate the function
at the start line. Timing does not begin until the wheel turns. The relationship
between remaining distance and elapsed time is constantly displayed so you
can apportion your effort. At the finish, lock in the time and distance
by pressing the left button. On any touring or training ride you can enter
the distance to a town, landmark, or ride's end from a map, road sign, or
from data collected previously by your Cyclometer. |
|
STOPWATCH. You can
time parts of your ride without affecting the average speed of the entire
ride, because Average Speed is calculated from Riding Time that has its
own timer. |
|
RIDE TIME. Riding time only accumulates
when the wheel is turning. Before an event with a standing start, you can
reset Average Speed and timing will begin automatically when the wheel turns.
Also, with time and distance displayed together, you can easily ride to
a schedule. For example, if you set a goal of two hours for 40 miles, Riding
Time will show you how much ahead of schedule or behind schedule you are
as you progress through the ride. |
|
MILES/KILOMETERS. Stored speed and distance
data are automatically converted to the units chosen. You can change from
miles to kilometers for a specific ride such as a 40 km time trial or for
a trip to a country where the metric system is used. Your accumulated miles
will be converted and not lost. You can also change during a ride to see
how fast you are going in km/h and how many kilometers you have travelled. |
|
TOTAL DISTANCE SETUP. When
you install a new battery, accumulated total distance is lost. You can reenter
this distance and you can also transfer distance from another computer by
adjusting the total distance accumulated on your Cyclometer 45tt. If you
want to use the Total Distance function as a second Trip Distance function,
you can adjust total distance to zero at the beginning of a week, month,
or multi-day tour to record weekly, monthly, or tour miles. |
|
SLEEP. If you will not be riding
your bicycle for several months you can put the Cyclometer to sleep to cut
power consumption by 50%. The Cyclometer also has an energy-saver feature
that displays the Clock only after 1-2 hours of inactivity. |
