CHAINRING SIZE LIMITATIONS
The design of the Jekyll’s swingarms limit the maximum usable chainring
size to 46 teeth. Use of any larger chainring may damage the swingarm or
result in contact between the front derailleur cage and the large chainring.
SWINGARM PROTECTOR
The swingarm on your Jekyll is made of thin wall aluminum tubing and
some CNC-machined aluminum parts. To protect the CAAD 4 swingarm
(found on some Jekyll models) from damage inflicted by the chain slap-
ping against the chainstay, we have supplied a self-adhesive vinyl pro-
tector for the swingarm. This protector should be applied to the top of the
right (drive side) chainstay, near the chain. Please inspect this protector
frequently. If the protector becomes damaged, abraded, or peels off, it
should be replaced to prevent damage to the swingarm. To obtain a new
swingarm protector, see an Authorized Cannondale Retailer. The elevated
(bonded) swingarm found on other Jekyll models doesn’t have a tradition-
al “chainstay”, but the protector can be applied to the bottom of the drive
side to protect the paint from chain slap.
ALTERNATIVE BRAKES
Hydraulic and disc brakes are a popular upgrade on many suspension
bicycles. When selecting a hydraulic brake system for your Jekyll, choose
one that mounts to the frame using only the existing cantilever brake
studs or disc brake caliper mounts. Do not attempt to modify the existing
cantilever brake studs or to clamp, weld, or to in any other way add new
or different mounts for a hydraulic brake or disc brake. Any attempt to
modify the frame, swingarm, fork, or related components will void the
warranty and may weaken or damage the frame. For installation instruc-
tions and other warnings, refer to the literature provided by the brake’s
manufacturer. The mounts on the Jekyll’s swingarm and fork are designed
to fit a CODA Compact Disc Brake caliper. Other brands of disc brakes
which conform to the international mounting standard may fit as well.
MAINTAINING THE APPEARANCE OF YOUR JEKYLL FRAME
To keep your Jekyll frame looking its best, we recommend cleaning it
regularly with mild soap and water. Regular cleaning will minimize the
chances of corrosion. Do not use abrasive cleansers or solvents. Jekyll
frames have a thin coating of clear paint over the whole frame (includ-
ing the decals.) A coating of wax can be applied if desired.
