The rings are the ones that came with the shimano octalink hollow cranks (22-32-44) that i'll soon replace with 26-36-48 and the cassette it's a MTB standard nine speed 11-30.

The chainguard is something i've been searching for a long time and one day we where for a walk while our holydays in the south of France and i saw a rent a bike shop, so i walked in and asked if they had chainguards that would fit a three ring drivetrain, they guy said "oui" and i bought two of them, one for me and one for my wife.

Besides that occasion i couldn't find then in any LBS but brands like SKS have them on their online catalog.

Truth is that they're really helpful when riding in street / office clothes.

Coque.

PS: BTW the chainguard is attached to the BB with a metal plate..
