Mudguard Assembly Instructions

CAUTION
Whilst fitting these mudguards:
• Confirm they are large enough for the tyres fitted to your bicy-
cle. “38mm” mudguards are suitable for Whyte Cambridge,
Cambridge Varsity, Carnaby, Charing Cross, Cornwall, Devon,
Dorset, Kings Cross, Pimlico, Portobello, Shoreditch, Somerset,
Stirling, Suffolk, Sussex, Victoria & Whitechapel models (Rigid
forks). “46mm” mudguards are suitable for Whyte Caledonian,
Chiltern, Coniston, Malvern & Ridgeway models (Suspension
Forks) and Fairfield (Rigid forks). The Montpellier & Stowe
models have no suitable mounting points for mudguards.
• Check that there will be at least 6mm clearance aroun
d the
tyre when they are fitted correctly.
• It is recommended to apply Loctite 243 Thread-Locker or simi-
lar thread adhesive to the threads of all screws that hold the
stays to either the fork or frame. This will help to ensure they
will not come loose. Carefully follow Loctite’s own assembly
instructions.
• SAFETY CHECK – CONFIRM THE CORRECT OPERATION OF
THE BRAKES AND GEARS AFTER FITTING THE MUDGUARDS. If in doubt either consult the manufacturer’s user
instructions or contact your Whyte Bikes dealer.
Before each and every ride:
• Check that all the fasteners holding the mudguards in place are
still tight.
• If necessary, clean and dirt or road debris from the
inside of
the mudguard, since this will reduce the clearance to the tyre.

• Insert a single side-stay (4)
through the threaded sleeve
(5) and also into the end of the
stay bracket (2). Screw the
sleeve (5) into the end of the
stay bracket (2) and lightly
tighten. Repeat this process
for the other items (1, 2, 4 &
5) on the other side of the
mudguard (3). Do not firmly
tighten the sleeves (5) just yet,
as the side-stays (4) may need
to be adjusted later.
• Remove the front wheel from
the bicycle (refer to page 15 of
the Whyte General Instruction Manual on
how to do this).
• For Rigid Forks
◊ Reference figures B & C. Depending on
the thickness of the front fork crown
(see Terminology), use either an M6 x
65 capscrew or an M6 x 60 long or 50
long button head cap-screw (8), plus
two small washers with Ø6 holes (9) and
an M6 Nylock hex nut (10) to attach the

• Reference figures R & S
(showing the inside of each
rear drop-out. Q = right
side & R = left side). For
frames with two M5 threaded holes in each drop-out,
the side-stays (4) should be
mounted on the INSIDE of
rear drop-outs alongside the
M5 threaded holes. This will
allow a rear luggage carrier
(20) to be fitted to the bicycle alongside the M5 threaded holes further down the
drop-out.
Using an M5 x 16 long button head cap-screw (21) and
washer with a Ø5 hole (7),
attach the looped end of the
side-stays (4) to the threaded holes in each of the rear
drop-outs. Ensure that the
side-stays (4) are in the correct location on the mudguard (14) and then tighten
both M5 x 16 long button
head cap-screw (21) into
the drop-outs, BEFORE the rear
wheel is re-fitted.
Reference figure T. For frames with
one M5 threaded hole in each dropout, the side-stays (4) should be
mounted on the OUTSIDE of rear
drop-outs alongside the M5 threaded
holes. Also, for carbon fibre frames,
