The place for fixies and other rides without gears

On my Giant Seek S, I have a Shimano Alfine 45T Octalink crankset. If you observe the pic (below), you will notice a plastic disc acting as a guard/chain channel retainer. Can I remove this, or does it physically need to be retained. It makes cleaning harder and I think it adds to chain slap.
Chainslap? Are you sure you're using the right term? If you're getting chainslap on a singlespeed, you are doing something dramatically wrong with your chain tension like having 5 or 6 link pairs too many..
As long as your chain line is straight, removal will have no performance impact.
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.
Sorry, chainslap was not the correct term. The chain is taut (enough) as it was recently serviced by my LBS. I thought I had noticed a bit of touching but I could be wrong. In any event it would a lot easier to clean if it were there. Can't catch any clothing as i wear knicks to work any, i will try and take it
Crank removal tool is required - after removing the allen key.
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.
Sorry, i don't understand what you are saying. Can you please elaborate for a noob. Specifically, how do i "just unbolt the chainring"
OK, you were looking at the central allen key bolt... around it are five more allen key sockets which you can undo. Undo those five and the chainring will come off as will the outer plastic gaurd.
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.
All of that makes sense, and yep i did know what the chainring was lol.
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
Wait... there is another issue...
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...
Yep - it will come off no probs.
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.
yep, 15 minute job for a bike shop.
