Hi Steve, yes they are trigon forks off EBAY they come direct from Taiwan they weigh 500 grams i,m only 11 st and I am pleased with them and i can see no problem with the extra weight the bars are from the same dealer these are Matix one piece carbon bar and stem and weigh 288 grams they are a bit short and can make the bike a bit twitchy but are good on narrow single track ,I ordered the bar,s and forks on friday morning and they were delivered on the monday from Taiwan and I had no problems at all. Donot bid the asking price try 15% less to start with he may  accept that if not go up a bit, climbed Alp d Huez four times on it last year and coming down it was steady as a rock it took every hairpin bend like it was on rails and not one thing past me on all four decents(some commuter bike)

I just use the one bike for every thing I have climbed every major coll in the Alps and the Pyrenees plus Ventoux with the bike in this set up and it takes me half an hour to put suspension forks and off road tyres on and then do MTB marathons plus downhill in France on it, you can all say what you like it,s my perfect bike and i would not swop it for anything else

in this setup it,s weight is 9 Kg

SQ tapper BB cost £10 three years ago ,took it out the weekend and it feels as good as the day it was fitted, its a giant XTC carbon frame and I cannot see the point in buying all this expensive gear when most of it wears out in no time and very few riders can notice any difference anyway
