SECTION 5—OPERATION
Recumbent Handcycle Series 28 Part No 1114850
Hands-On Rapid Fire Shifter/Brake System: Twenty-seven Speeds
NOTE: For this procedure, refer to FIGURE 5.3 on page 29.
NOTE: This procedure applies to the Top End XLT Pro, XLT Gold, and Force ONLY.
To shift gears, you MUST turn the crank forward with the chain under some tension while
the bike is moving. DO NOT attempt to shift gears while bike is stationary.
There are two shifters installed on the handcycle. The right shifter operates the nine gears
on the lower derailleur and the manual shifter operates the three chain rings on the upper
derailleur. Nine gears X three chain rings = Twenty‐seven speeds.
Shifting the chain on the lower derailleur towards the centerline of the handcycle is for
climbing/accelerating (easier cranking) (lever A) and is called a downshift. Moving the
chain on the lower derailleur out or away from the centerline of the handcycle is for speed
(harder cranking) (lever B) and is called an upshift.
Refer to the chart below for an explanation and use of the upper derailleur chain rings in
combination with the lower derailleur gears:
Each shifter has a large lever (brake handle), a medium lever (shifter lever “A”) and a
small lever (shifter lever “B”). The right and left shifters work in an opposite manner.
CAUTION
DO NOT press both shifter levers down at the same time. Doing so may damage
the shifter and will void the warranty. The gears WILL NOT shift when both levers
are pressed simultaneously.
DO NOT use excessive force. This may damage the shifter and void the warranty.
Lower Derailleur (Right Side Shifter)
• Shifting from Harder Gears to Easier Gears (Downshift) ‐ Push shift lever “B” and
release. Repeat until the desired gear is achieved.
• Shifting from Easier Gears to Harder Gears (Upshift) ‐ Pull shift lever “A” and
release. Repeat until the desired gear is achieved.
Upper Derailleur (Manual Shifter)
• Shifting from Easier or Smaller Chainring to Harder or Larger Chainring (Upshift)
‐ Push lever up until chain runs smoothly over the chain ring teeth while the
handcycle is moving.
• Shifting from Harder or Larger Chainring to Easier or Smaller Chainring
(Downshift) ‐ Push lever down until chain runs smoothly over the chain ring teeth
while the handcycle is moving.
