^just tried mine for peace of mind having not greased in ages. Seems fine to me. May well be quite specific to the one you purchased. IIRC yours may well be the one that was on gumtree then ebay, the seat post clamp area looked a bit rough...previous owner may have bodged and then deformed it. Track champs are reknowned for hairline cracks in the same area.
