Ongoing clearout (all offers entertained) - 4600 groupset, 3TTT randonneur bars, Halo Aerorage front wheel

Have a bunch of assorted bits to get rid of which I have decided I am not ever going to use; letting them go for any reasonable offer (or forum donations for the smaller items) because I want this stuff gone:

1. Tiagra 4600 compact silver 9 speed mini-group (flightdeck shifters, 170mm cranks, front der, rear der, front brake calliper - have given the rear calliper to a friend). Can include the very worn cassette if desired. (£30)
   
2. White halo aerorage front wheel, used condition but with plenty of life left in rims, no tubes/tires (£15)
   
3. 3TTT 380mm morphe bars. These are randonneur and have an extra 'bend' and I've really liked the hand position it gives in the drops. Would keep using them but my new bike is threadless. Think the clamp dia is 25.8 or something. (£15)
   
4. Topeak cargo net (for big baskets/crates) (£5 or free with anything else)
   
5. WTB saddle (Freecycle)
   
   

Pretty centrally London based for collection, could potentially post smaller items.
