To make rear wheel removal

easier place the chain intothe highest gear (smallest cog)

on the cassette

Well o rim

Pushing the tyre into the centre

o the rim

The tyre can be easily removed by using the Well o the rim a rim is concaved

in prole, which results in a small circumerence in the centre o the rim

compared to the edge (where the tyre will normally sit). Pushing one side into the

well reduces the tension between the tyre and rim, making tyre lever use easier.

Use one lever to start, letting the

hook section hold on to a spoke,

then using the second with

controlled orce, slowly slide

round the rest o the rim to unseatthe rest o the tyre.

Incorrect

Correct

Careully explore the tyre checking or anything that may have caused a

puncture, this could be a piece o glass, a thorn, damaged tyres or even the tube

getting pinched (aka snake bite).

Remove any object that may have caused the puncture (there may not actually be

anything!), i the tyre is badly damaged then a new one should be installed.

Reseating the tyre is easy i you ollow

the below instructions:

I. Place one side o the tyre on the rim rst

II. Inate the tube so that it holds some shape, but does not expand

III. Put the valve through the valve hole

IV. Seat the tube into the tyre rom the side that has not been placed on the rim

V. Start installing the other side o the tyre rom the valve

VI. When it starts to get tight, go back to the valve and push the tyre into the Well

VII. Then roll the last section on with your palms around the tyreDO NOT USE TYRE LEVERS

VIII. Check that the tube has not been pinched by the tyre

Align the valve

with the logo

Check the rotatingdirection is correct

Reinstall the wheel:

7

When reinstalling the wheel it is important to get the axle seated correctly in the

drop outs (orks or rame), this can be achieved by pulling the wheel up then

tightening the quick release. Once this is done, reattach the brakes, then do a spin

test to see i the wheel is located in the correct place. ie. Shouldnt rub on pads.

IX. Inate to 20psi, then check the seating

X. Once the seating is correct inate to the recommended pressure(this will be ound embossed in the rubber o the side wall, like the rotation direction)

This line should be the same distance

rom the rim all the way round the wheelNot disappearing under

the rim like this one

Clean the drive chain using a tool such as

the Park Chain Cleaner

Examine or damage/wear:

Cleaning

the drive chainin 4 simple steps

Beore using the chain cleaner you must

rst ll it with a suitable degreaser

A visual inspection is required to see i the chain rings/cassette is

worn, the at section o the tooth should look like the picture below.

The shape o the tooth on the right indicates

that it is airly worn, however there is a more

ool proo and cheap way o checking, Park

make a simple Chain Checker tool.

And not like...

Check alignment o Rear Derailleur:3

Parks Chain Checker tool in action:

A visual check o the rear derailleur alignment now needs to be completed,

the jockey wheels (small cogs on the rear derailleur) need to be in line with the

cassette when viewed rom behind:

A worn chain The tool drops in the

chain, this means that it is time or a

service at one o our stores.

An unworn chain The tool sits proud o

the chain. With cleaning and re-lubing

your chain will stay like this or longer.

Hanger

Lubrication:4Ater cleaning and checking/aligning the next step is lubricating. This is vital

to stop any rusting and reduce the wear on the chain, reducing the requency

and cost o ull servicing. You must clean the chain rst, otherwise it is a bit like

using deodorant without washing, smells ok or a bit but it really stinks quickly!

With the bike stationary, cycle the pedals backwards dripping the oil onto the

chain, complete 3 chain revolutions, then leave or 1 hour (this allows the lube to

penetrate the chain). Reapply the same amount o oil by the same method ater

the hour, then use a cloth to wipe of excess oil.

The bike is now ready to ride.

Gear

Location o Barrel adjuster:

The eect they have:

in 4 simple stepssetup

Turn the adjuster on the derailleur,shiter or down tube clockwise

and the derailleur will move to the

right (into a smaller cog) helping i

shiting up a gear is sticky.

Turn the adjuster on the derailleur,shiter or down tube anti-clockwise

and the derailleur will move to the let

(into a bigger cog) helping i shiting

down a gear i s sticky.

Barrel adjusters allow the user to increase or decrease the tension onthe gear cables, thus changing the alignment o the rear derailleur

with the cassette and changing the way it shits gear.

The barrel adjusters are on the gearing system to provide a quick and

easy way to x shiting problems.

Indexing:3

With the derailleur in this position

on the outer (largest) chain ring

the rider will be able to use thehighest gear (smallest cog) on the

cassette.

With the derailleur in this position on theouter (largest) chain ring the rider will be

able to use the lowest gear (largest cog) on

the cassette.

Trim/micro shit:4 Road bikes with double rings at the ront have an extra amount o adjustment,the ront derailleu r/shiter i s able to have two positions per chainring (a total o4 possible positions), this is to allow the rider to use all o the cassette without

incurring chain rub on the ront derailleur (see below).

Indexing is getting the shi ter to correspond with the selected gear, i.e. 1

on the shiter equals 1 on the cassette.

Using the barrel adjuster the whole o the gearing range should index

accordingly, with 1=1 2=2 3=3 4=4, and so on.The shit should also be smooth, when you change the gear rom 1 to 2 the

chain should glide efortlessly rom the largest cog to the 2nd largest cog on

the cassette.

Use the barrel adjuster to get this perect, then shit all the way up the gears,

one click at a time, and then all the way down the gears one click at a ti me

this should be smooth and exact .

Brake

Location o Barrel adjuster:

Centering brakes:

1

2

in 4 simple stepssetup

Using the screws on the brake arms

(spring tension screws) you can increasethe tension on the spring or that side,

making the arm move away rom the rim.

Barrel adjusters on brakes do the same thing as gears increaseor decrease the cable tension; this results in a change o distance

between the brake pad and the rim surace, the efect or the user will

be a change in the biting point during the brake lever stroke.

Basically the more tension you have the sooner the lever gets hard to

pull, the lower the tension the urther the lever travels beore you get

any braking power, in extreme cases this can result in the lever hitting

the bar and no braking power transerred to the wheel.

Most road

bikes

have sel-centering

calipers.

Pad placement :

You should aim or the

bite point to be here:

The barrel adjuster should be tweaked

(turned anti-clockwi se) i the bite point is here:

When you should use the barrel adjuster:

4As explained on page 12 the barrel adjuster should only be used when the lever

has excessive pull. By unscrewing the barrel adjuster the pad will hit the rim

sooner in the lever stroke making the brake tighter.

Once centred, the pad alignment needs to be

set so that when pulled the brake pads hit the rim square and do not touch the tyre,

there is a picture o this below:

bike servicing

Additional

www.evanscycles.com/servicing

We ofer two maincategories o service:Stage 1 and a stage 2...

Astage 1 service is a generala check-over or your bike

and is recommended to be

carried out every 3-9 months*.Astage 2 service is a completeoverhaul and involves

stripping your bike down to

the rame and its components.

This is recommended to

be carried out every 12-18

months*. We also carry out

suspension servicing which

we recommend every 3-12

months*. In addition we oer

a ull range o other servicing

rom wheel building to

repairing a puncture or ftting

a light set. *Recommendations

dependent on use.

14

Our workshops are ully equipped to carry out all

necessary repairs and have between two and eight

qualied mechanics per store, dependent on size. All o

our mechanics undergo regular assessment, are trained

to the highest standards in the industry and receive

ormal external recognition with Cytech qualications.

We are the only cycle retailer that has its own dedicated

ull-time mechanic trainer and in-house training

acility. This enables us to ensure that our mechanicsmaintain the high standards we set.
