<HTML>yello. i'm not sure if you're talking newer or older model derbis. i have a 1989 derbi variant sport and as much as i like the ped it has yielded a lot of hassle. first off it was close to impossible to get replacement sprockets for it as no dealers anywhere it seems carry anything at least for older derbis. and right after i fixed that now something else has gone wrong with it and due to cold weather blues i haven't had a chance to fix it yet. they are really nice peds and all but i think there's better choices out there.
