Front guides for Singlespeed

[Err]

I don't understand how the front downhill/jump style chain guides mount. Do these bikes have bolt holes round the bb? Or will i be able to fit then to a regular frame, an old gt outpost in this case.

you could use a iscg adaptor. international standard chain guide. there are various companies that do them. dmr, e-13 etc

they mount behind the fixed cup of the b\b and give you 3 holes to bolt to. then you can mount the chainguide of your choice.
