The 29.8mm will refer to the seatpost diameter not the tube diameter.
I have a new Shimano LX FC-T671 with 48/36/26 rings, comes with the matching outboard bottom bracket., bought it for my audax bike but got a shiny black miche triple to match the frame..Though technically a '10 speed' c/set the rings on these work fine with 9 speed chains.
I also have a new (fitted but used on a display bike) Shimano 9 speed 12-27 cassette and also a new/fitted but not used 53 link HG53 (plus a used quick link)
£64 posted for the chainset, £13 posted on the cassette, £7 for the chain. If you take the lot then £80 including tracked courier.
