my bottom bracket is very much on the way out and needs to be replaced, this is a little disappointing as it's only been  around 900 miles- being pressfit, what are my options?

 

can I just use a adaptor to convert to threaded ?

Yup, need too get the right one though, I had a bike that I bought provided shop fitted one, had that bike for a couple years (so 3-4,000 miles) before I changed bikes.

They look a bit like this:-

yeah I was looking at that and the FSA aluminium - am I right in thinking with the (threaded) BB bearings now being on the outside, I'd need to replace my crank as it wont be long enough?

 

I didn't even think about BB when buying the bike... my old trek had a square taper which still runs smooth after at least 7K miles

I'm a bit late to this party, but wondered what you did in the end?
I had a similar dilemma, but ultimately replaced a PF30 with another, primarily because I'd need to buy the threaded conversion kit spanners too, so was not worth it on a mid level Boardman.
Encouragingly, (and possibly because of the lashings of grease) the new PF30 is thus far silent.

I pulled my old BB out which almost came out by hand it was that rubbish

 

unfortunately my bike has a strengthening bar in the middle of the BB which ruled out many options but I Installed a wheels manufacturing pressfit which has cups that screw togeather very similar to the pf30 I also used loads of assembly compound and retaining compound to reduce any possible movement and loads of grease for the dust covers and  so far it's been fine I've done about 500 miles on dusty gritty trails and no issues so.l assume all good 

 

now I've moved onto new grips/bars/saddle to get the position dialled in.
