Plastic guard removal ok?

The outer guard helps to stop trouser legs from getting eaten by the bike. The inner guard is unlikely to do anything.
It is unlikely to do anything for chain slap. On a single speed chain slap should not be happening at all.

Crank removal tool is required - after removing the allen key.lucifuge wrote:To remove the crankset, do i just need to use an appropriate Allen key in the centre of the crankset....or is it complicated?

Such as: http://www.cyclingexpress.com/cycle/acc ... cp-44.aspx (and this is an expensive one).
EDIT - according to the Giant AUS website, your bike is running an Octalink crankset - which is why I linked the tool above.
However - to remove the plastic guards, just unbolt the chainring. You'll be able to take the guards off without removing the crank.

The inner plastic gaurd is probably just held on with some small screws to the chainring.
FYI - the chainring is the ring with the teeth the chain runs on.

But, while i can loosen the plastic guard no problem at all, i can't see how it will come off given your'e saying the crank will stay on the bike in this process. Its a closed piece of plastic, t wont simply drop off

The outer chainring is likely alloy.
The bolts holding the chainring and outer plate are sized for both of these rings.
To remove the outer plate and refit the chainring - you will also need some new chainring bolts. Known as "track chainring bolts" (for Track bikes). These are still quite cheap by the way, so not much to worry about.
Some people just use washers to space out the gap left on the original bolts. Up to you.
It will.... it will...lucifuge wrote:But, while i can loosen the plastic guard no problem at all, i can't see how it will come off given your'e saying the crank will stay on the bike in this process. Its a closed piece of plastic, t wont simply drop off

Yep - it will come off no probs.lucifuge wrote:http://www.shimano-benelux.com/media/te ... 637967.pdf
But I stress - you do have a small issue with the chainring bolts which will need to be addressed before you ride the bike with the guard removed.

Just get the shop to remove it and fit new (shorter) cahin ring bolts next time it's serviced.
