FR-5 Cassette Lockring Tool
A cassette lockring tool is used to remove and
install the cassette lockring and cogs on the rear
wheel. The FR-5 fits Shimano, SRAM, SunRace,
and other 12-tooth cassette lockrings.
Instructions:
Lockring Removal: Fit cassette lockring tool
into splines of lockring and install quick release
skewer to prevent tool from slipping. Hold
cassette cogs with chain whip (Park Tool SR-11)
and turn cassette lockring tool counterclockwise
with adjustable wrench until lockring is removed.
Lockring Installation: Fit cassette lockring tool
into splines of lockring and turn clockwise with
wrench until tight.
Instructions:
Locate cut or tear then clean and dry surrounding
surface to promote adhesion of boot. Peel
the protective backing from TB-2 and apply,
allowing TB-2 to adequately overlap damaged
area. Note: The TB-2 is designed for emergency
use. A patched tire should be replaced as soon
as possible.
GSC-1 GearClean Brush
The GSC-1 is specially designed to remove dirt,
grit, and grime from the sprockets on the rear
wheel. Just insert the curved end of the GSC-
1 between the gears and pedal backwards.
Then use the brush end to remove the loosened
dirt and grit. Also works great for cleaning
derailleurs, brakes and anywhere grease and
dirt collect.
SR-11 Chain Whip
The SR-11 is used when removing cassette cogs
from the rear wheel. It firmly holds the cassette
cogs so a cassette lockring tool can be used to
remove the cassette lockring.
TL-6 Tire Levers
Tire levers are designed to remove and install
tires from the rim of a wheel. TL-6 Tire Levers
have a steel core that is covered with a special
composite material to prevent scratching
of carbon fiber, anodized and painted rims.
Instructions:
Deflate tire completely. Push bead of tire from
edge of rim. Insert tip of one lever under bead.
Insert tip of second lever under bead 8 - 10 cm
from first lever. Push down on both levers to pry
up bead. Slide second lever along rim until bead
is completely removed. Remove second tire bead
from rim to completely remove tire and tube.

Professional Spoke Wrenches
A wheel occasionally needs to be straightened
or “trued” in order to keep the rim running
straight as it passes between the brake pads.
A spoke wrench is required for tightening and
loosening spoke nipples when truing a wheel.
SW-0 (Black): .127 (3.23mm)
SW-2 (Red): .136 (3.45mm)
Instructions:
Detailed instructions for truing wheels can
be found in a number of books, as well as
on-line at www.parktool.com. Below are
instructions for basic lateral truing, which
can easily be performed with the wheel in
the bike (more advanced truing requires the
wheel to be removed from the bike and trued
in a truing stand, such as the Park Tool TS-2.2
or TS-8).
TB-2 Emergency Tire Boot
Designed to get you back on the road or trail, the
TB-2 Tire Boot quickly and easily installs to patch
cuts, scrapes, and tears in any size tire. The thin,
reinforced tire boot film adheres to the inside of
the tire and prevents the tube from protruding
out of the cut or tear.
