WARNING Be careful not to pay excessive attention to the computer data while riding, otherwise you might have an accident. 1.
2. Display Contents mode 1 Clock (CLK) Trip time (TIM) Trip distance (DST) ODO meter (ODO) mode 2 Current speed (VEL) Cadence (rpm) Stop watch Stop watch– trip distance (DST STW) Stop watch– average speed (AVE STW) Stop watch– maximum speed (MAX STW) Main display cadence Maximum speed Average speed Lap counter No.
3. Name and function of each part (1) Current speed (VEL) Front When main display cadence appears on top Main Display 1. Current speed (VEL) 8. Cadence 2. Gear indicator (bar) km/h, mph 0.0 (2.0) - 130.0km/h 0.0 (1.2) - 80.0mph (Range) The current speed will appear at the top of the main display.
(4) Trip distance group (TIM, DST, MAX, AVE) (5) ODO meter (ODO) 0 - 99999.9 km, mile The trip distance group includes the trip time (TIM), trip distance (DST), maximum speed during the trip (MAX) and the average speed during the trip (AVE). To activate the trip distance group, press the Mode button until “TIM” is displayed, and then press the ST/SP button. Displays the cumulative distance travelled.
(7) Cadence (rpm) (10) Digital number of gear teeth (F- R) Cadence is calculated from the F - R gear tooth numbers and current speed. Gear combinations are displayed when a shift has been made. This will show for approx 2 seconds then original screen will return. Note; Cadence always appears during bicycle movement regardless if the crankarms are rotating. (11) Low battery display (LO BAT) (8) Main display cadence (VEL) Cadence (rpm) can also be shown in main display.
4. Changing the setting data and the bicycle number Changing the setting data Changing the bicycle number 5. Viewing data after removing the computer from the bracket mount The data can still be viewed even when the computer has been removed from the handlebar bracket. Display other than CLK display mode1 mode2 CLK rpm STW TIM VEL DST, STW DST MAX AVE, STW ODO AVE MAX, STW STW CNT Switch “B” 5 seconds Bicycle number is displayed Switch “B” Tire circumference setting mode is displayed.
7. Installation to the bicycle Install the levers to the handlebars. Then connect and adjust the brake and shifting cables. Refer to the STI Lever Service Instructions for details on these procedures. (1) Installing the signal cable (SM-SC70/SM-6501) Fig.1 Install the signal cable as shown in Figure No1. Tightening torque: 0.3 - 0.5 N·m { 2 - 4 in. lbs.
[ Example 2028 - 2032mm 2033 - 2037mm 2038 - 2042mm •••••• •••••• •••••• 2030mm 2035mm 2040mm ] The display will appear as shown in fig9, Enter the value which was measured previously. Roll forward Fig.9 Check whether the front chainwheel is a single, double or triple chainwheel. Wheel circumference • • • • • Single Check whether the cassette has 7, 8, 9, or 10 sprockets.
(4) Entering the number of chainring and sprocket teeth The display will then change to that shown in fig10. Fig.10 Inner chainring Outer chainring Front chainring Rear sprocket Low gear No. of teeth for largest chainring The following tooth numbers are pre - set into the computer No.1 Switch “B”: Accept Switch “A”: Change value Top gear No.2 No.3 No.
If the cassette has seven sprockets, press switch “A” once to change the flashing “21” to “- -”, and then press switch B once. This will indicate that there is no 8th sprocket, and the operation for entering the number of sprocket teeth will be complete. If the cassette has 8 sprockets, enter the number of teeth for this position and follow the same procedure as above to enter “- -” in the 9th position otherwise enter the number of teeth for the 9th sprocket.
