If for any reason the eccentric must be removed from the bike or replaced, it is
very important that the outer surfaces (including under the wedge) are thoroughly
coated with anti-seize compound or greased before re-installation. Also, the
eccentric MUST be re-installed with the head of the hex bolt on the right side of
the bike to assure that the bottom bracket is installed the correct direction.
Chainring bolts
: should be periodically checked for tightness, particularly the
five inside bolts that secure the two innermost chainrings. Torque these bolts to
110 In-Lbs (11Nm)
.
Front derailleur adjustment:
It is very important that the front derailleur lower
limit screw be set accurately to avoid the chain accidentally shifting from the
inner chain wheel (the third chain wheel in, also known as the “granny”) onto
the primary drive chain (which turns the fourth chainring in).
Brake set up:
Please see enclosed brake manufacturers instructions. Set up is
as on a conventional bike, with one exception. The front “V” brake guide tube,
often called the “noodle”, is a special part. This special noodle has a tight 120
degree radius, rather than the standard 90 degrees. This additional bend,
combined with precise casing length of 11-3/8 inches (29cm) and careful casing
routing prevents the front brake cable and casing from conflicting with the right
pedal or crank. The front brake casing should have minimal slack when the fork
is fully extended. See the photos inside the front cover of this booklet for a
guide to cable routing.
CARRYING STUFF
The tubing on the back of the seat back:
is 22.2mm (7/8”) outside diameter.
This is standard handlebar diameter. You can use many handlebar bags
designed to fit handlebars. Follow the bag manufacturer’s instructions.
Day packs/Back packs/Hydration packs:
fit nicely over the seat back. Be
sure both shoulder straps are inboard of the vertical frame members. Attach the
waist belt, and any sternum strap, around the seat back to keep the pack
stable. Be sure that no straps hang low enough to tangle in the rear wheel.
Panniers:
A rack will be available that attaches to the base of the seat
assembly. The seat assembly is pre drilled and tapped (standard M6) to accept
this pannier rack. This rack will accept a pair of medium panniers, one on each
chainrings and is the heart of the mid-drive system. The inner chainring is
driven by the front crankset via the front chain. The outer three chainrings are
used exactly as the chainrings on any triple crankset conventional bicycle. The
drivetrain is exactly as on any conventional bicycle.
The mid-drive crankset spins on a two special bearings pressed into a recess
on the back of the crankset. These bearings ride on a special shaft threaded
into the drive side of the mid-drive bottom bracket. The bearings are sealed and
maintenance free, but if new ones are needed they can be replaced. To do so,
remove the M6 bolt on the front of the mid-drive crankset. To replace it, torque
the bolt to
77-94 In-Lbs (8.7-10.6 Nm)
before riding.
Front chain tensioner:
The front chain is tensioned using the same patented
bottom bracket eccentric adjustment mechanism used in Cannondale tandems.
Your Easy Rider will be delivered with this mechanism properly adjusted. If you
think that the front chain seems to have excessive slack, let your retailer take a
look. A properly adjusted front chain will not bind or feel tight at any point in a
rotation of the crankset and will not have excess slack in the chain.
Adjustment: As the chain wears and stretches, use the eccentric to return the
chain to a maximum of 1/2” of vertical chain deflection between the two cranks.
1. Using a 4mm hex wrench, turn the socket head bolt on the right side of the
eccentric counter-clockwise to loosen the eccentric assembly. If the bolt has
been previously installed tightly it will be necessary to tap the head of the bolt
with a mallet to free the wedge (much like a stem wedge) assembly.
2. Once the assembly is free, use a bottom bracket pin tool such as the Park
SPA-1 (green) to rotate
the eccentric until proper
chain tension is
obtained. Secure the
assembly in its new
position, centered in the
frame, by tightening the
hex bolt clockwise to
60
In-Lbs. (6.75 Nm)
.
