Name of bit to stop trousers meeting chain

edited July 2010 in The workshop
I want to buy something that fixes to the frame to shield my flapping trouser leg from the chain and front rings.
It's for a hybrid type bike with a front derailleur (triple ring). It would have the extra advantage (I hope) of stopping the front ring from chewing my shoes laces as well. I have seem them in smoked black plastic and they looked okay.
The trouble is that I don't know what they are called. I have typed in chain guard in cycle websites and it doesn't work. So what are they called ? And do you know who sells them ?

    Me again. It isn't just the chainrings it covers but the top run of the chain as well. I cannot find a picture unfortunately.
  • cheaper alternative for your trousers :)

    You could try tying your laces shorter in a double knot as well

    On motorcycles they are called chain guards. I don't know how to paste a picture though.

    Have a look at a Hebie Triple Chainguard (not the Chainglider, I think). Havn't tried it myself, so I'd be interested to hear your thoughts...

    Look up a picture of a Trek District. This comes with a grey chainguard. If this looks like it would fit your steed then pm me as I have one spare (took it off my bike) in unused perfect condition. Very light painted aluminium.

    The telephone lines are now closed. Thank you very much for all your replies.

    The Hebie chainguard (no idea how to pronounce Hebie - German company - did French at school) looks good to me. I noticed that the Trek District is a single speed bike so the chain guard wouldn't fit (sorry, but thank you) because I need it for a triple ring (48t). Another company (SKS - also German I believe) do a chainguard but it looks a bit agricultural (in photos).

    You will have to wait a while for the user review as (a) I need to summon up the courage to meddle with the bottom bracket and (b) my bicycle is in Denmark.

    I have got trouser bands which I do use but I wanted the cycle to be more hop on, hop off. The laces on my trainers are double knotted but they still catch in the teeth.

    A lbs would fit it for you so you would not need to remove bottom bracket.

    I think that's called "lower leg"...

    If & when you set this up, I'd be interested to hear whether you think it would work with a 52T chainring. They specify 48, I know, but it's only an extra 4mm... :-)

    I can't help thinking that a chainguard would make a big difference to drivetrain life on the winter hack, but I'm currently running a 52T steel ring.

    Yes, I wondered if that would be another side effect. It seems to me that the chainrings are directly in the path of road spray from the front tyre and consequently they and the chain would be nicely 'washed' after a ride in the rain. I have got fairly good mudguards anyway which help.
    As I say the bike is residing in Copenhagen. Their cycle culture is very much more advanced than ours and they would sooner ride the bike than drive in most situations for travel around the city e.g. shopping, visiting friends, going out. That's why I wanted to make my cycle as easy to use as possible so nothing round the trousers, not putting shorts on, not riding one legged.

    If it were washed I'd be less concerned...'cos that implies clean.

    Offhand, I can't think of a better way to accelerate wear in a drivetrain than to spray it with a fine mist of salt water and sand during operation under load...
